8.3.4. The type of PPE required must be based on a completed risk assessment of the hazards, exposure and the controls in place to protect lab workers during experiments or procedures. The Laboratory Hazard Assessment Tool (LHAT) can be used or workers can contact EHS at 330-672-4347 for assistance.

8.3.5. The Principal Investigator is responsible for ensuring that the appropriate PPE is used at all times.

8.3.6. Each laboratory is responsible for providing a sufficient supply of personal protective equipment for all workers.

8.3.7. All personal protective equipment should be inspected and cleaned on a routine basis to assess if there are any defects or potential problems. Each lab should outline in their laboratory chemical hygiene plan a description of PPE maintenance.

8.3.8. Never launder PPE at home, always use the facilities on campus if accessible or a commercial laundromat or contracted laundering service

8.3.9. Eye Protection

8.3.9.1. Safety glasses with side shields must be used to provide the minimum protection for regular use to minimize the risk of eye injury.

8.3.9.2. Eye protection is required in any laboratory irrespective of whether the individual is performing a “chemical operation,”.

8.3.9.3. Regular prescription glasses and contact lenses do not provide adequate protection against eye injury. Safety glasses should be worn over prescription glasses. Prescription safety glasses can also be purchased to perform your work.

8.3.9.4. Eye protection should be cleaned on a routine basis with water, lens cleaning towelettes or microfiber cloths. Appropriate storage of glasses in pouches is recommended to protect glasses from damage (e.g. scratches)

8.3.10. Skin Protection

8.3.10.1. Skin protection must always be used when working with substances, chemicals or materials that are corrosive or easily absorbed by the skin.

8.3.10.2. Skin protection includes protective clothing, shields, gloves, aprons, lab coats and other protective equipment that shield or provide a barrier between the hazard and the body.

8.3.10.3.   Skin protection should be selected based on the type of work. Selection of the appropriate protection can be determined using the Ansell Guardian Protection Guide at or . Contact EHS at 2-4347 if assistance is needed.

8.3.11. Respirators

8.3.11.1. Work that may generate dust, fumes, mists, gases, vapors, or aerosols, and /or expose workers to extreme temperatures or oxygen deficient environments may require the use of a respirator.

8.3.11.2. If a half mask, full mask or air supplied respirator is needed you must contact EHS at 2-4347 to get enrolled into the �鶹��ý Respiratory Protection Program before using the respirator. For more information contact EHS at 2-4347 or visit the EHS website.

8.3.12. Hearing Protection

8.3.12.1. If the noise or sound level in the work environment exceeds 85 decibels (dB) over an 8 hour day then hearing protection is required. The worker must be enrolled in the �鶹��ý Hearing Protection Program. For more information contact EHS at 2-4347 or visit the EHS website.

8.3.12.2. Examples of hearing protection may include earmuffs, earplugs or semi-insert earplugs.

8.3.12.3.  Headphones and earbuds are not sufficient protection for these environments and should not be used.

9.  Chemical Hazard Classification

9.1.Chemicals can be divided into several different hazard classes.  The hazard class will determine how a chemical should be stored and handled and what special equipment and procedures are needed to use them safely.

9.2.Each chemical container, whether supplied by a vendor or produced in the laboratory, must include labels that clearly identify the hazards associated with that chemical. In addition to specific chemical labels, hazard information for specific chemicals can be found by referencing the Safety Data Sheet (SDS) for that chemical.

9.2.1. All secondary containers must be labeled with the chemical name (in English), signal word, hazard statement, pictograms and date of transfer or preparation.

9.2.2.  Secondary containers are one to which a chemical or chemical product is transferred or the container in which a new chemical product/reagent is made and stored.

9.2.3.Immediate Use containers are containers which are only expected to last one work shift and are not intended to leave the control of the person who filled them.

9.3 It is essential that all laboratory workers understand the types of hazards, recognize the routes of exposure, and are familiar with the major hazard classes of chemicals. In many cases, the specific hazards associated with new compounds and mixtures will not be known, so it is recommended that all chemical compounds be treated as if they were potentially harmful and to use appropriate eye, inhalation and body protection equipment.

9.4.   Corrosives

9.4.1 A corrosive substance is defined by OSHA as a chemical that can destroy skin tissue.

9.4.2. Acids and bases are the most commonly used corrosive materials in the laboratory.

9.4.3. When working with concentrated corrosive solutions, a full-length lab coat, splash goggles, and chemical resistant gloves must be worn. The use of a face shield over the goggles or glasses protects the entire face in the event of a splash.

9.4.4. These materials must always be used in the chemical fume hood to avoid the inhalation of the vapors.

9.4.5. Acid should always be added to water slowly to avoid splatter.

9.4.6. All labs using corrosive materials must install an eyewash and emergency shower that meets ANSI Z358.1 standard (See Eyewash Station and Emergency Shower Section for requirements).

9.4.7.Hydrofluoric Acid is a particularly hazardous corrosive substance and requires a SOP, with associated training. The antidote, calgonate, should also be placed in the first aid kit in each lab using hyrofluoric acid.

9.4.8. Perchloric acid is a powerful oxidizing agent that may react explosively with organic compounds and other reducing agents. It shall be used only in a perchloric-acid, water-wash-down fume hood of noncombustible construction.

9.4.9. Strong bases are all corrosive and can cause serious chemical burns. Bases generally have good warning properties: they typically have a slippery feeling on the skin. However, if it is not completely removed by rinsing, a solution of a strong base may not cause pain until the corrosive damage is quite severe.

9.4.10. Formaldehyde, formalin, paraformaldehyde, and phenol are corrosives that do not fall into the acid and bases categories discussed above. Formaldehyde is a colorless gas with a pungent odor and is most commonly used as a saturated aqueous solution called formalin. Formaldehyde is a suspected carcinogen.

9.4.11. Phenol is a colorless or pink crystalline solid or viscous liquid with a characteristic sweet, medicinal odor. It is corrosive and considered moderately toxic. Phenol is capable of rapidly penetrating the skin and causing severe burns. It is toxic and even fatal amounts of phenol can be absorbed through relatively small areas of skin.

9.4.12. Care should be taken when storing corrosive materials.   The following protocol should be followed.               

• Nitric acid should be stored separately or in secondary containment from other acids.
• Acids and bases shall be stored separately.
• Perchloric acid shall be stored separately from other acids.
• Glacial acetic acid, even though corrosive shall be stored with the flammable substances.

Table 1: Corrosives

9.5 Flammable and Combustible

           9.5.1.   A flammable liquid is a liquid with a flash point below 100 °F and a vapor pressure not exceeding 40 psi (absolute) at 100 °F. These are categorized as Class I liquids. A liquid with a flash point of 100 °F or greater is classified as a combustible liquid and may be referred to as a Class II or Class III liquid.

Table 2: Flammable Substances

9.5.2. Flammable solids often encountered in the laboratory include alkali metals, magnesium metal, metallic hydrides, some organometallic compounds, elemental phosphorus, sulfur, and powdered metals. Many flammable solids are also considered highly reactive chemicals.

9.5.3. Flammable aerosols as a category are flammable gases compressed, liquefied, or dissolved under pressure, and fitted with a release device allowing the contents to be ejected as particles in suspension in a gas, or as a foam, paste, powder, liquid, or gas. They present multiple hazards including the flammability of the compressed material and hazards associated with compressed gases.

9.5.4. An oxidizing agent is a chemical that has the ability to oxidize other substances, in other words, to cause them to lose electrons. Some oxidizers can spontaneously evolve oxygen at room or slightly elevated temperatures, and can explode violently when shocked or heated. Because they possess varying degrees of chemical instability, oxidizing agents can be explosively unpredictable and, therefore, can be particularly hazardous. Examples of oxidizing agents includes peroxides, hyper peroxides, and peroxyesters.

9.5.5.  Explosive and reactive (unstable) chemicals can be identified a few different ways. The label or SDS may include the pictograms  above, the SDS may include the H codes and statements discussed below, or they may fall into one of the categories discussed further in this section. Some common examples are listed in the table below.

Table 3: Explosive and Reactive Chemicals

9.6 Irritants

9.6.1.. Irritants are defined as non-corrosive chemicals that cause reversible inflammatory effects on living tissue by chemical action at the site of contact.

9.6.2. A wide variety of organic and inorganic compounds, including many chemicals that are in a powder or crystalline form, are irritants. The most common example of an irritant may be ordinary smoke which can irritate the nasal passages and respiratory system.

9.6.3. Consequently, eye and skin contact with all laboratory chemicals should always be avoided.  Symptoms of exposure can include reddening or discomfort of the skin and irritation to respiratory systems.

9.7 Sensitizers

9.7.1. A sensitizer (allergen) is a substance that causes exposed people to develop an allergic reaction in normal tissue after repeated exposure to the substance.

9.7.2. Examples of sensitizers include diazomethane, chromium, nickel, formaldehyde, isocyanates, arylhydrazines, benzylic and allylic halides, and many phenol derivatives. Sensitizer exposure can lead to all of the symptoms associated with allergic reactions, or can increase an individual’s existing allergies.

9.8 Reactivity Hazards

9.8.1. Reactive and explosive substances are materials that decompose under conditions of mechanical shock, elevated temperature, or chemical action, and release large volumes of gases and heat.

9.8.2. Some materials, such as peroxide formers, may not be explosive, but may form explosive substances over time. These substances pose an immediate potential hazard and procedures which use them must be carefully reviewed.  

9.8.3. These materials must also be stored in a separate flame-resistant storage cabinet or, in many cases, in a separate laboratory grade refrigerator or freezer that is designed for flammable/ reactive chemicals.  

9.8.4. Peroxide formers can only be stored in refrigerators when unopened. Once used, they must be stored in a dry environment. Peroxide formers, such as diethyl ether, should also be dated when received and again when opened.

9.8.5. Pyrophoric chemicals are a special classification of reactive materials that spontaneously combust when in contact with air and require laboratory-specific training.

9.8.6.  Flame-resistant laboratory coats or other appropriate flame-resistant protection must always be worn when working with pyrophoric chemicals, along with flame-resistant gloves and training.

9.7.7.  When ordering picric acid, the PI must inform EHS.   This substance should be stored separately and should be disposed of within two years of purchase.

9.9 Hazardous Substances with toxic effects on specific organs

9.9.1.  Substances included in this category include items in Table 4.

Table 4: Specific Organ Toxicity

9.9.2. Symptoms of exposure to these materials vary.  Personnel working with these materials should review the SDS for the specific material being used, take special note of the associated symptoms of exposure, and contact EHS for assistance.

9.10 Particularly Hazardous Chemicals

9.10.1. OSHA recognizes that some classes of chemical substances pose a greater health and safety risk than others. To differentiate this different risk characteristic, OSHA identifies two categories of hazardous chemicals.

• Hazardous chemicals.
• Particularly hazardous substances.

9.10.2. Substances that pose such significant threats to human health are classified as "particularly hazardous substances" (PHSs).  The OSHA Laboratory Standard regulation require that special provisions be established to prevent the harmful exposure of researchers to PHSs, including the establishment of designated areas for their use.

• Use of containment devices such as fume hoods or glove boxes;
• Procedures for safe removal of contaminated waste; and
• Decontamination procedures.

9.10.3. Particularly hazardous substances are divided into three primary types:

9.10.3.1. Acute Toxins

Substances that have a high degree of acute toxicity are interpreted by OSHA as being substances that "may be fatal or cause damage to target organs as the result of a single exposure or exposures of short duration.” These chemicals, associated chemical waste, and storage containers must be handled with care to prevent cross contamination of work areas and unexpected contact.  These chemicals must be labeled as “Toxic.”  Empty containers of these substances must be packaged and disposed of as hazardous waste without rinsing trace amounts into the sanitary sewer system.

9.10.3.2. Reproductive Toxins

Reproductive toxins include any chemical that may affect the reproductive capabilities, including chromosomal damage (mutations) and effects on fetuses (teratogenesis).

Reproductive toxins can affect the reproductive health of both men and women if proper procedures and controls are not used. For women, exposure to reproductive toxins during pregnancy can cause adverse effects on the fetus; these effects include embryo lethality (death of the fertilized egg, embryo or fetus), malformations (teratogenic effects), and postnatal functional defects.  For men, exposure can lead to sterility.

Examples of embryo toxins include thalidomide and certain antibiotics such as tetracycline.  Women of childbearing potential should note that embryo toxins have the greatest impact during the first trimester of pregnancy.  Because a woman often does not know that she is pregnant during this period of high susceptibility, special caution is advised when working with all chemicals, especially those rapidly absorbed through the skin (e.g., formamide).  Pregnant women and women intending to become pregnant should consult with their laboratory supervisor and EHS before working with substances that are suspected to be reproductive toxins.

9.10.3.3. Carcinogens

Carcinogens are chemical or physical agents that cause cancer.  Generally they are chronically toxic substances; that is, they cause damage after repeated or long-duration exposure, and their effects may only become evident after a long latency period.  Chronic toxins are particularly insidious because they may have no immediately apparent harmful effects. These materials are separated into two classes: 

 

Select carcinogens are materials which have met certain criteria established by the National Toxicology Program (NTP) or the International Agency for Research on Cancer (IARC) regarding the risk of cancer via certain exposure routes. It is important to recognize that some substances involved in research laboratories are new compounds and have not been subjected to testing for carcinogenicity.  The following references that can be used to determine which substances are select carcinogens.

•  published by the National Toxicology Program (NTP), including all of the substances listed as "known to be carcinogens" and some substances listed as "reasonably anticipated to be carcinogens" based on the below standard
• , including all of Group 1 "carcinogen to humans," and some in Group 2A “probably carcinogenic to humans” or 2B, "possibly carcinogenic to humans" based on the below standard
• For substances listed in either Group 2A or 2B by IARC or under the category “reasonably anticipated to be carcinogens” by NTP, to be considered a “select carcinogen” by OSHA, it must also cause statistically significant tumor incidence in experimental animals in accordance with any of the following criteria:
  • after inhalation exposure of 6-7 hours per day, 5 days per week, for a significant portion of a lifetime to dosages of less than 10 mg/m3;
  • after repeated skin application of less than 300 mg/kg of body weight per week;
  • after oral dosages of less than 50 mg/kg of body weight per day  

Regulated Carcinogens fall into a higher hazard class and have extensive additional requirements associated with them. The use of these agents may require personal exposure sampling based on usage. When working with Regulated Carcinogens, it is particularly important to review and effectively apply engineering and administrative safety controls as the regulatory requirements for laboratories that may exceed long term (8 hour) or short term (15 minutes) threshold values for these chemicals are very extensive.

9.11 Nanomaterials

9.11.1. Nanomaterials: Exposure standards have been proposed for only a limited number of engineered nanomaterials (e.g. carbon nanofiber, silver, titanium dioxide) in the US. However, none have been adopted as regulatory standards.  See  Table 5  for types of nanomaterials.

9.11.2. Until more definitive standards are developed based on the understanding of nanomaterial toxicology, and the potential health risks associated with handling nanomaterials, researchers should take a conservative approach when planning to work with nanomaterials, and where applicable, implement a combination of advisory engineering controls, work practices, and PPE to minimize potential workplace exposures.

9.11.3. A detailed Standard Operating Procedure (SOP) for working with nanomaterials should be written to provide guidance on appropriate work practices, engineering controls, personal protective equipment (PPE), and waste disposal practices depending on the risk level of a particular nanomaterial or process involving a nanomaterial.

9.11.4. For further information, see the “Nanotool kit: Working Safely with Engineered Nanomaterials in Academic Research Setting”, the National Institute of Occupational Safety & Health’s (NIOSH) “General Safe Practices for Working with Engineered Nanomaterials in Research Laboratories" and the NIOSH “Current Strategies for Engineering Controls in Nanomaterial Production and Downstream Handling Processes.”

Table 6:  Nanomaterial Risk Category

10.  Chemical Storage and Inventory.

10.1 Regulatory Requirements

Implementation of the necessary work practices, procedures, and policies outlined in this chapter is required by the following: 

 

10.2 Chemical Inventories

10.2.1. Faculty members and other supervisors with chemicals are required to use the campus inventory system to maintain a current, accurate and complete chemical inventory that includes the hazardous materials, solids, liquids, gases, and gels used and stored in the rooms to which they are assigned.  The information maintained in the inventory includes the name of the chemical, the concentration, the chemical abstracts number, the size of the container, the amount on hand, the physical state, the type of the container, whether it is pure or a mixture and both the storage pressure and temperature. Chemical inventories are used to provide the required information to the fire department, ensure compliance with fire code storage limits, and homeland security reporting thresholds. The chemical inventory can also be used in an emergency to identify potential hazards for emergency response operations and more.

10.2.2. The chemical inventory list should be reviewed prior to ordering new chemicals and only the minimum quantities of chemicals necessary for the research should be purchased.  As new chemicals are added to the inventory, each laboratory group can confirm that they have access to the Safety Data Sheet (SDS) for that chemical through  .  Where practical, each chemical should be dated so that expired chemicals can be easily identified for disposal.  Inventory the materials in your laboratory at least annually to avoid overcrowding with materials that are no longer useful and note the items that should be replaced, have deteriorated, or show container deterioration. The Department of Homeland Security (DHS) maintains a list of “,” and requires a report to be submitted within 60 days if specific chemicals on that list exceed set threshold aggregate amounts.  Unneeded items should be given to EHS and should be discarded as chemical waste.  If substances are usable, these may be added to the CEMS database as surplus.   Attributes that may indicate the materials need to be disposed are cloudiness in liquids, a change in color, evidence of liquids in solids, or solids in liquids, “puddling" of material around outside of containers, pressure build-up within containers and obvious deterioration of containers in addition to exceeding a manufacturer’s expiration date.

10.2.3. Access to hazardous chemicals, including toxic and corrosive substances, should always be restricted.  These materials must be stored in laboratories or storerooms that are kept locked when laboratory personnel are not present.  Locked storage cabinets or other precautions are always recommended, and in some cases may be required in the case of unusually toxic or hazardous chemicals. Unusually toxic chemicals may include those that are immediately dangerous to life or health (IDLH).  

10.2.4. On termination or transfer of laboratory personnel, all related hazardous materials should be properly disposed of, or transferred to the laboratory supervisor or a designee.  

10.2.5. To facilitate improved inventory management and reporting, Kent State has implemented a systemwide(program for maintaining inventory. Information on how to use the Kent State Chemical Database system is available on the EHS page. This program allows Kent State to comply with both long more easily-standing and new regulations requiring chemical inventory maintenance and reporting. OSHA’s “Hazard Communication” standard requires that employers develop and maintain a list of hazardous chemicals known to the workplace. This is a long-standing regulatory requirement and is an important component of  lab safety evaluations. Maintenance of the chemical inventory by individual labs allows for accurate compliance with this mandate.” requires that employers develop and maintain a list of hazardous chemicals known to the workplace.

10.3 Chemical Labeling

10.3.1. All containers (including diluted chemical solutions and those with abbreviations) of hazardous materials must be labeled with the identity of the hazardous substance and all applicable hazard warning statements or abbreviations. If abbreviations are used, a list of the abbreviations used, the full chemical names and the hazards warning statement associated with each, must be prominently displayed in each room.  In either case, all containers not actively being used, in transfer, or a reaction must be labeled. New synthesized compounds must be labeled, to the best of your knowledge,  with the appropriate hazard warnings based on the knowledge of the chemical and physical properties of that substance.   Unlabeled compounds should be assumed as highly hazardous chemicals, until proved otherwise.

10.3.2. Labels must be legible, in English, and clearly displayed.  Label the containers as thoroughly as possible.   Lewis structure should be used if no other information is available. Secondary containers (such as spray bottles) must be labeled with the identity of the substance and appropriate GHS hazard warnings.

10.3.3. Symbols and/or other languages may be provided for non-English speaking employees. Use the symbols in the . 
 
10.3.4. Peroxide forming chemicals (e.g., ethers) must be labeled with a date on receipt and the date when the bottle is first opened. Any unopened chemicals that are listed in Classes A through D that have been listed in the chemical inventory for a minimum of one year must be opened and tested for peroxides.   See appendix for a guide to peroxide formers.  These chemicals can degrade to form shock sensitive, highly reactive compounds and should be stored and labeled very carefully.

10.3.5. Particularly Hazardous Substances require additional labeling to identify the specific hazard associated with each of these chemicals (carcinogen, reproductive toxin, acutely toxicant). In addition, the storage area where they are kept must be labeled with the type of hazard. These chemicals should be segregated from less hazardous chemicals to help with proper access control and hazard identification.

10.4.  Chemical Storage & Segregation

Establish and follow safe chemical storage & segregation procedures for your laboratory. 
10.4.1. Storage and segregation guidelines are included for materials that are flammable, oxidizing, corrosive, water reactive, explosive, and highly toxic.

10.4.2. For general guidelines on segregation and storage, EHS has developed a Chemical Segregation Guidance Sheet  to assist with developing storage plans for hazardous chemicals. The specific Safety Data Sheet (SDS) should always be consulted when doubts arise concerning chemical properties and associated hazards.

10.4.3. All procedures employed must comply with, OSHA, Fire Code and building code regulations.  

10.4.4. Always wear appropriate personal protective equipment (e.g., laboratory coat, safety glasses, gloves, safety goggles, apron) when handling hazardous chemicals.

10.4.5. Be aware of the locations of the safety showers and emergency eyewash stations.  Each laboratory is required to provide appropriate laboratory-specific training on how to use this equipment prior to working with hazardous chemicals.  

10.5. Safe Chemical Storage Priorities

Keep in mind that most chemicals have multiple hazards, and a decision must be made as to which storage area would be most appropriate for each specific chemical. First you must determine your priorities:

1. Flammability. When establishing a storage scheme, the number one consideration should be the flammability characteristics of the material. If the material is flammable, it should be stored in a flammable cabinet or, if necessary an explosion proof refrigerator.
2. Isolate. If the material will contribute significantly to a fire (e.g., oxidizers), it should be isolated from the flammables. If there were a fire in the laboratory and response to the fire with water would exaggerate the situation, isolate the water reactive material away from contact with water.
3. Corrosivity. Next look at the corrosivity of the material, and store accordingly.
4. Toxicity.  Finally, consider the toxicity of the material, with particular attention paid to regulated materials. In some cases, this may mean that certain chemicals will be isolated within a storage area. For example, a material that is an extreme poison but is also flammable, should be locked away in the flammable storage cabinet to protect it against accidental release.
5.  There will always be some chemicals that will not fit neatly in one category or another, but with careful consideration of the hazards involved, most of these cases can be handled in a reasonable fashion.

10.6. General Recommendations for Safe Storage of Chemicals

10.6.1. Each chemical in the laboratory should be stored in a specific location and returned there after each use.

10.6.2. Acceptable chemical storage locations may include corrosive cabinets, desiccators, flammable cabinets, laboratory shelves, or appropriate refrigerators or freezers. In general, fume hoods should not be used as permanent storage areas for chemicals, as this may seriously impair the ventilating capacity of the hood.  

10.6.3. Chemicals should not be routinely stored on bench tops or stored on the floor.  Additionally, bulk quantities of chemicals should be stored in a separate storage area, such as a flammable cabinet or stockroom or supply room.

10.6.4. Laboratory shelves should have a raised lip along the outer edge to prevent containers from falling. Hazardous liquids, toxic or corrosive chemicals should not be stored on shelves above eye-level and chemicals which are highly toxic, or corrosive should be in unbreakable secondary containers. 

10.6.5. Chemicals must be stored at an appropriate temperature and humidity level and should never be stored in direct sunlight or near heat sources, such as laboratory ovens.  

10.6.6. Incompatible materials should be stored in separate cabinets, whenever possible.  If these chemicals must be stored in one cabinet, due to space limitations, adequate segregation and secondary containment must be ensured to prevent adverse reactions.  

10.6.7. All stored containers and research samples must be appropriately labeled and tightly capped to prevent vapor interactions and to alleviate nuisance odors.  Caution should be used with flasks with only septa, cork, rubber or glass stoppers.

10.6.8. Laboratory refrigerators and freezers must be labeled appropriately with “No Food/Drink” and must never be used for the storage of food or drinks intended for human consumption.  Freezers should be defrosted periodically so that chemicals do not become trapped in ice formations. Never store flammables in a refrigerator not specifically designed for storage of flammable liquids. 

10.7. Flammable and Combustible Liquids

10.7.1. In general, flammables should not be stored alongside combustible materials like paper and packaging plastic bags.

10.7.2. Large quantities of flammable or combustible materials should not be stored in the laboratory. The Fire Code limits specific volume of flammable materials or other classes of hazardous chemicals depending on the original design and construction of the facility and varies from building to building.

10.7.3. In most labs, the maximum total quantity of class 1A, 1B and 1C flammable liquids must not exceed 60 gallons, which must all be stored in a flammable storage cabinet.

10.7.4. The maximum quantity allowed to be kept outside a flammable storage cabinet, safety can, or approved refrigerator/freezer is 10 gallons per room. Class 1A solvents, such as ethyl ether, should be purchased only in one gallon (4 liter) or smaller containers.

10.7.5. Because of the extreme flammability of the Class 1 liquids, only quantities needed for immediate use should be present in the work area.  The rest should be stored.    Examples of equipment that can be used for storage include flammable storage cabinets, flammable storage refrigerators or freezers that are designed and UL approved for the storage of flammable substances, or approved safety cans or drums that are grounded.

10.7.6.  Always segregate flammable or combustible liquids from oxidizing acids and oxidizers.  Flammable materials must never be stored in domestic-type refrigerators/freezers.

10.7.7.  Flammable or combustible liquids must not be stored on the floor or in any exit access.

10.7.8. Handle flammable and combustible substances only in areas free of ignition sources and use the chemical in a fume hood whenever practical.  Only the amount of material required for the experiment or procedure should be stored in the work area.

10.7.9.  Always transfer flammable and combustible chemicals from glass containers to glassware or from glass container/glassware to plastic. Transferring these types of chemicals between plastic containers may lead to a fire hazard due to static electricity. The transfer of flammable liquid from 5 gallon or larger metal containers should not be done unless the container is grounded and bonded.

Table 1:  Classification of Flammables.

10.8 Pyrophoric & Water Reactive Substances

10.8.1. The basic requirements for pyrophoric material usage are as follows:

The laboratory space must meet the requirements for safe use and storage of pyrophoric material.

• Ideally, material should be used and stored in a fully sprinklered lab, as approved by the Fire Marshal, and appropriate storage must be available and used.  Use caution if labs are not sprinklered.
• Inventory must be regularly managed, and annually certified, using the CEMS system.
• Review of the Kent State SOP on pyrophorics.
• Users of pyrophoric materials are required to take the Pyrophoric training course in Flashtrain.
• Users must use flame resistant gloves based on the PPE section of the SDS.

10.8.2. Because pyrophoric substances can spontaneously ignite on contact with air and/or water, they must be handled under an inert atmosphere and in such a way that rigorously excludes air and moisture. Some pyrophoric materials are also toxic and many are dissolved or immersed in a flammable solvent. Other common hazards include corrosivity, teratogenicity, or peroxide formation.

10.8.3. Only minimal amounts of reactive chemicals should be used in experiments or stored in the laboratory. These chemicals must be stored as recommended in the SDS. Reactive materials containers must be clearly labeled with the correct chemical name, in English, along with a hazard warning.

10.8.4. Suitable storage locations may include inert gas-filled desiccators or glove boxes; however, some pyrophoric materials must be stored in a flammable substance approved freezer.  If pyrophoric or water reactive reagents are received in a specially designed shipping, storage or dispensing container (such as the Aldrich Sure/Seal packaging system), ensure that the integrity of that container is maintained.  Ensure that sufficient protective solvent, oil, kerosene, or inert gas remains in the container while pyrophoric materials are stored.  Never store reactive chemicals with flammable materials or in a flammable liquid's storage cabinet.

10.8.5. Storage of pyrophoric gases

Gas cabinets, with remote sensors and fire suppression equipment, are required.  Gas flow, purge and exhaust systems should have redundant controls to prevent pyrophoric gas from igniting or exploding. Emergency back-up power should be provided for all electrical controls, alarms and safeguards associated with the pyrophoric gas storage and process systems.

10.8.6. Never return excess reactive chemical to the original container. Small amounts of impurities introduced into the container may cause a fire or explosion.  For storage of excess chemical, prepare a storage vessel in the following manner:

a. Dry any new empty containers thoroughly.

b. Insert the septum into the neck in a way that prevents atmosphere from entering the clean  dry (or reagent filled) flask;

c. Insert a needle to vent the flask and quickly inject inert gas through a second needle to  maintain a blanket of dry inert gas above the reagent;

d. Once the vessel is fully purged with inert gas, remove the vent needle then the gas line. To introduce the excess chemical, use the procedure described in the handling section of the SOP;

e. For long-term storage, the septum should be secured with a copper wire or hose clamp

f. For extra protection a second same-sized septa (sans holes) can be placed over the first; and

g. Use “Parafilm M®” or equivalent around the outer septa and remove the Parafilm M® and      outer septum before accessing the reagent through the primary septum.

Oxidizers (e.g., oxygen, ozone, hydrogen peroxide, and other inorganic peroxides; fluorine, chlorine, and other halogens; nitric acid and nitrate compounds; persulfuric acids; chlorite, chlorate, perchlorate, and other analogous halogen compounds; hypochlorite and other hypohalite compounds, including household bleach; hexavalent chromium compounds such as chromic and dichromic acids and chromium trioxide, pyridinium chlorochromate, and chromate/dichromate compounds; permanganate compounds; sodium perborate; nitrous oxide; silver oxide; osmium tetroxide; Tollens' reagent; 2,2'-dipyridyldisulfide) should be stored in a cool, dry place and kept away from flammable and combustible materials (e.g., wood, paper, Styrofoam^TM, most plastics), flammable organic chemicals, and reducing agents (e.g. zinc, alkaline metals, and formic acid).

10.10. Peroxide Forming Chemicals

10.10.1.  Peroxide forming chemicals are able to form shock sensitive peroxide crystals. Peroxide crystals can be explosive when concentrated or as solids, which can occur if peroxide forming material is allowed to dry on the outside of a container. Many organic solvents are peroxide formers to some degree.

• Ethers, acetals, and ketals, especially cyclic ethers and those with primary and/or secondary alkyl groups
• Aldehydes, including acetaldehyde and benzaldehyde
• Compounds containing benzylic hydrogens, and
• Compounds containing allylic hydrogens, including most alkenes, vinyl, and vinyl diene compounds and dienes.

10.10.2. Some of the more common peroxide forming chemicals used in research laboratories are tetrahydrofuran (THF), dioxane, diethyl ether, and isopropyl ether. All peroxide forming chemicals should be stored in airtight containers in a dark, cool, and dry place and must be segregated from other classes of chemicals that could create a serious hazard to life or property should an accident occur (e.g., acids, bases, oxidizers, highly toxic materials).  The containers should be labeled with the date received and the date opened. This information, along with the chemical identity should face forward to minimize container handling during inspection. These chemicals must also be tested and documented for the presence of peroxides annually. Minimize the quantity of peroxide forming chemicals stored in the laboratory and dispose of peroxide forming chemicals before peroxide formation.

10.10.3. Carefully review all cautionary material supplied by the manufacturer prior to use. Avoid evaporation or distillation, as distillation defeats the stabilizer added to the solvents.  Ensure that containers are tightly sealed to avoid evaporation and that they are free of exterior contamination or crystallization. Never return unused quantities back to the original container and clean all spills immediately.

10.10.4.  If old containers of peroxide forming chemicals are discovered in the laboratory, (greater than two years past the expiration date or if the date of the container is unknown), do not handle the container. If crystallization is present in or on the exterior of a container, do not handle the container. Secure it and contact EHS for pick-up and disposal.

10.11. Corrosives

10.11.1. Corrosive materials cause irreversible damage to skin or metals. Store corrosive chemicals (i.e., acids, bases) below eye level and in secondary containers that are large enough to contain at least 10% of the total volume of liquid stored or the volume of the largest container, whichever is greater.  Acids must always be segregated from bases and from active metals (e.g., sodium, potassium, magnesium) at all times and must also be segregated from chemicals which could generate toxic gases upon contact (e.g., sodium cyanide, iron sulfide).

10.11.2.  Specific types of acids require additional segregation. Mineral acids must be kept away from organic acids and oxidizing acids must be segregated from flammable and combustible substances.  Perchloric acid should be stored by itself, away from other chemicals.  Picric acid is reactive with metals or metal salts and explosive when dry and must contain at least 10% water to inhibit explosion.   Glacial acetic acid shall be stored in a flammable cabinet.

10.12. Special Storage Requirements

10.12.1. Compressed Gas Cylinders

Correct storage of compressed gas cylinders

10.12.2. Compressed gas cylinders that are stored in the laboratory must be chained or strapped to the wall or other stable building member, with the safety cap in place. The cylinders must be restrained by a chain, two chains preferred; one chain should be placed at one third from the top of the cylinder, and the other placed at one third from the bottom of the cylinder. If this is not practical, contact EHS for guidance. Bolted “clam shells” may be used in instances where gas cylinders must be stored or used away from the wall.  Store liquefied fuel-gas cylinders securely in the upright position.

Cylinders are not to be stored in a horizontal position. Do not expose cylinders to excessive dampness, corrosive chemicals, or fumes.

10.12.3. Certain gas cylinders require additional precautions. Flammable gas cylinders must use only flame-resistant gas lines and hoses which carry flammable or toxic gases from cylinders and must have all connections wired. Compressed oxygen gas cylinders must be stored at least 20 feet away from combustible materials and flammable gases.

10.12.4. Gas cylinder connections must be inspected frequently for deterioration and must never be used without a regulator. Never use a leaking, corroded or damaged cylinder and never refill compressed gas cylinders. When stopping a leak between cylinder and regulator, always close the valve before tightening the union nut. The regulator must be replaced with a safety cap when the cylinder is not in use. Move gas cylinders with the safety cap in place using carts designed for this purpose, and do not use carts for storage of cylinders. Please refer to the gas cylinder procedures on the  EHS website for more details.

10.12.5. Liquid Nitrogen.  Protection considerations should be addressed when storing liquid nitrogen in a laboratory.  The primary risk to laboratory personnel from liquid nitrogen is skin or eye thermal damage caused by contact with the material.  In addition, nitrogen expands 696:1 when changing from a cryogenic liquid to a room temperature gas.  The gases usually are not toxic, but if too much oxygen is displaced, asphyxiation is a possibility.  Consider an oxygen sensor in a small space.   Always use appropriate thermally insulated gloves when handling liquid nitrogen. Face shields may be needed in cases where splashing can occur.   A diffuser is recommended for dispensing liquid nitrogen.

10.13. Laboratory Security

10.13.1. Recently regulatory agencies have been implementing rules to ensure chemical security. While many of these rules are for large manufacturing facilities, it is critical that chemicals be secured to prevent theft from campus laboratories. Numerous federal agencies are involved in the maintenance of laboratory security, including the Drug Enforcement Agency, Federal Bureau of Investigations, and Department of Homeland Security. It is each laboratory’s responsibility to prevent and report any theft of chemicals from their laboratory.

10.13.2. Laboratories can increase their security by simply keeping lab doors closed and locked when unoccupied, maintaining a current and accurate chemical inventory, training personnel on security procedures, and controlling access to keys. Labs should report any suspicious activity to the Kent State Police department and EHS.

10.14. On-Campus Distribution of Hazardous Chemicals

10.14.1 Precautions must be taken when transporting hazardous substances between laboratories. Chemicals must be transported between stockrooms and laboratories in break-resistant, secondary containers such as commercially available bottle carriers made of rubber, metal, or plastic, that include carrying handle(s) and which are large enough to hold the contents of the chemical container in the event of breakage. A cart is also recommended when transporting chemicals.   Wear PPE, eg., safety glasses and gloves).

10.14.2. When transporting cylinders of compressed gases, always secure the cylinder with straps or chains onto a suitable hand truck and protect the valve with a cover cap. Avoid dragging, sliding, or rolling cylinders and use a freight elevator when possible. The figure below illustrates correct cylinder transport.   Do not ride elevators with liquified gases.

Gas cylinder cart

Liquified Gas Cart

10.14.3. The transportation of hazardous chemicals and compressed gases over public roads, or by air, is strictly governed by international, federal, and state regulatory agencies, including the U.S. Department of Transportation (DOT) and the International Air Transport Association (IATA).  Any person who prepares and/or ships these types of materials must ensure compliance with pertinent regulations regarding training, quantity, packaging, and labeling.  Without proper training and packaging, it is illegal to ship hazardous materials.  Those who violate the hazardous materials shipment regulations are subject to criminal investigation and penalties. Individuals who wish to ship hazardous materials off-campus must contact EHS.

5.  Training

5.1. Environmental Health and Safety Department Training (EHS)

5.1.1. All lab personnel are required to complete the initial laboratory safety training provided by EHS before beginning any work in the laboratory. Contact EHS at 2-1944 or visit the EHS website �鶹��ý EHS Website for training information.

5.1.2. The EHS training will cover general safety topics and �鶹��ý specific procedures. Training topics will include �鶹��ý Laboratory Chemical Hygiene and Safety Plan, chemical storage and segregation, emergency planning, chemical fume hoods, personal protective equipment, chemical transport, spill control, hazardous waste, safety data sheets (SDS), flammable and combustible liquids, compressed gas cylinders, hazard identification, risk assessment, and chemical security.

5.1.3. Additional general safety training modules can be assigned to specific laboratories based on the hazards present in the laboratory.

5.1.4. The EHS training must be taken every three years] a refresher by all laboratory workers (Principal Investigators, faculty, staff, students, graduate assistants, teaching assisting, visiting scholars and volunteers etc.).

5.2. Fire Extinguisher Training

11.   Chemical Exposure Assessment

11.1. Regulatory Requirements

11.1.1. It is University policy to comply with all applicable health, safety and environmental protection laws, regulations and requirements. PERRP(Public Employee Risk Reduction Program) requires that all employers “measure an employee’s exposure to any substance regulated by a standard which requires monitoring if there is reason to believe that exposure levels for that substance exceed the action level (or in the absence of an action level, the exposure limit).” Repeated monitoring may be required if initial monitoring identifies employee exposure over the action level or exposure limit. 

11.1.2. OSHA regulates Permissible Exposure Limits (PELs) for airborne contaminants to which “nearly all workers may be exposed daily during a 40-hour workweek for a working lifetime (of 40 years) without adverse effect”, are based upon an 8-hour Time-Weighted Average (TWA) exposure. Thus, the PELs are the maximum permitted 8-hour TWA concentration of an airborne contaminant without respiratory protection. OSHA has also defined Short Term Exposure Limits (STELs) as the maximum TWA exposure during any 15-minute period, provided the daily PEL is not exceeded and Ceiling (C) exposures that shall not be exceeded at any time.

11.1.3. OSHA has listed established PELs, STELs and Ceiling exposures for chemical contaminants in the .  In the absence of a published Ceiling limit, OSHA requires employee exposure to concentrations above the PEL be controlled to prevent harmful effects. Further, OSHA has promulgated specific standards covering several regulated carcinogens, which may include an Action Level (AL), triggering medical surveillance requirements or the imposition of a specific Excursion Limit (such as for asbestos) with a unique measurement of the duration of an exposure.

11.2. Exposure Assessment Overview

11.2.1. All Kent State employees require protection from exposure to hazardous chemicals above PELs, STELs and Ceiling concentrations. The profession with expertise in exposure assessment monitoring is Industrial Hygiene. At Kent State, the person supervising, directing, or evaluating the exposure assessment monitoring must be competent in the practice of industrial hygiene. EHS employs personnel with this expertise or will use a consultant. General questions regarding exposure assessment can be directed to EHS.

11.2.2. Minimizing exposure may be accomplished using a combination of engineering controls, administrative controls and personal protective equipment, listed in order of priority. Assessing exposure to hazardous chemicals may be accomplished through several methods performed by EHS, including employee interviews, visual observation of chemical use, evaluation of engineering controls, use of direct reading instrumentation, or the collection of analytical samples from the employee’s breathing zone.

11.2.3. Personal exposure assessment will be performed under either of the following situations:

11.2.3.1 Based on chemical inventories, review of Standard Operating Procedures (SOPs), types of engineering controls present, laboratory inspection results and/or review of the Laboratory Hazard Assessment Tool or other reasoning, EHS determines whether an exposure assessment is warranted; or user of a hazardous chemical has concern or reason to believe exposure is not minimized or eliminated through use of engineering controls or administrative practices and the potential for exposure exists. The user should then inform his or her PI/Laboratory Supervisor, who will in turn contact EHS.  EHS will then determine the best course of action in assessing employee exposure, including visual assessment, air monitoring, medical evaluation, examination, or medical surveillance.

11.2.3.2. In the event of any serious injury or exposure, including chemical splash involving dermal or eye contact, immediately call 911 and obtain medical treatment immediately. Do not wait for an exposure assessment to be performed before seeking medical care.  For minor injuries, such as a localized, small burn from hydrochloric acid, first aid in the lab may be sufficient. If you believe a call to 911 is necessary, do not hesitate.  Seek immediate care if there are any concerns.

11.3. Exposure Assessment Protocol

11.3.1. EHS, or their delegate, can conduct exposure assessments for members of the campus community.

11.3.2. Employees have a right to observe testing, sampling, monitoring or measuring of employee exposure. They are also allowed access to the records and reports related to the exposure assessment.

11.3.3.  Exposure assessments may be performed for hazardous chemicals, as well as for physical hazards including noise and heat stress to determine if exposures are within PELs or other appropriate exposure limits that are considered safe for routine occupational exposure.

11.3.4. The costs of exposure monitoring are the responsibility of the lab, department and organization in which the personnel are employed. 

11.3.5. General protocol in conducting an exposure assessment may include any of the following:

• Employee interviews;
• Visual observation of chemical usage and/or laboratory operations;
• Evaluation of simultaneous exposure to multiple chemicals;
• Evaluation of potential for absorption through the skin, mucus membranes or eyes;
• Evaluating existing engineering controls (such as measuring face velocity of a fume hood);
• Use of direct reading instrumentation; and
• Collection of analytical samples of concentrations of hazardous chemicals taken from the employees breathing zone, or noise dosimetry collected from an employee’s shirt collar or various forms of radiation dosimetry.

11.3.6. If exposure monitoring determines an employee's exposure to be over the action level (or the PEL) for a hazard for which OSHA has developed a specific standard (e.g., lead), the medical surveillance provisions of that standard shall be followed.

11.3.7. It is the responsibility of the PI/Laboratory Supervisor to ensure that any necessary medical surveillance requirements are met.  When necessary, EHS will make recommendations regarding adjustments to engineering controls or administrative procedures to maintain exposure below any applicable PEL. Where the use of respirators is necessary to maintain exposure below permissible exposure limits, Kent State will provide, at no cost to the employee, the proper respiratory equipment and training.

11.3.7.1. Respirators will be selected and used in accordance with the requirements of the    University’s Respiratory Protection Program.

11.3.7.2. In assessing exposure to hazardous chemicals for which OSHA has not published a PEL, STEL or Ceiling exposure, EHS defers to the Threshold Limit Values (TLVs) established by the           American Conference of Governmental Industrial Hygienists (ACGIH) or the Recommended      Exposure Limits (RELs) established by the National Institute of Occupational Safety & Health     (NIOSH). Please contact EHS for more information regarding these chemicals.

11.37.7.3.  If a mask is worn for nuisance dust, or any contaminant below the PEL, a voluntary use form must be signed by the user.

11.4. Notification

11.4.1. EHS will promptly notify the employee and his/her PI/Laboratory Supervisor of the results in writing) after the receipt of any monitoring results. EHS will establish and maintain an accurate record of any measurements taken to monitor exposures for each employee. Records, including monitoring provided by qualified vendors, will be managed in accordance with OSHA guidelines.

11.5. Exposure Assessment Use to Determine and Implement Controls

11.5.1 EHS will use any of the following criteria to determine required control measures to reduce employee’s occupational exposure:

• Verbal information obtained from employees regarding chemical usage;
• Visual observations of chemical use or laboratory operations;
• Evaluation of existing engineering control measures or administrative practices;
• Recommendations expressed in Safety Data Sheets;
• Regulatory requirements of OSHA;
• Recommendations from professional industrial hygiene organizations;
• Direct reading instrumentation results;
• Employee exposure monitoring results; and/or
• Medical evaluation, examination and/or surveillance findings.

11.5.2.  Particular attention shall be given to the selection of safety control measures for chemicals that are known to be extremely hazardous. Per OSHA, the control of harmful exposures shall be prevented by implementation of control measures in the following order:

• Engineering controls, whenever feasible;
• Administrative controls whenever engineering controls are not feasible or do not achieve full compliance and administrative controls are practical; and
• Personal protective equipment, including respiratory protection, during:
  • The time necessary to install or implement feasible engineering controls
  • When engineering and administrative controls fail to achieve full compliance
  • In emergencies
  • As an extra precaution/option for employees

11.6. Medical Evaluation

11.6.1. All employees, including laboratory personnel, who work with hazardous chemicals shall have an opportunity to receive a free medical evaluation, including supplemental examinations which the evaluating physician determines necessary, under the following circumstances:

• Whenever an employee develops signs or symptoms associated with a hazardous chemical to which an employee may have been exposed in a laboratory;
• Where personal monitoring indicates exposure to a hazardous chemical is above an OSHA Action Level (AL) or Permissible Exposure Limit (PEL) or recommended exposure levels established by the National Institute for Occupational Safety & Health (NIOSH) or the American Conference of Governmental Industrial Hygienists (ACGIH) in the event OSHA has not established an AL or PEL for a particular hazardous chemical;
• Whenever an uncontrolled event takes place in the work area such as a spill, leak, explosion, fire, etc., resulting in the likelihood of exposure to a hazardous chemical; or
• Upon reasonable request of the employee to discuss medical issues and health concerns regarding work-related exposure to hazardous chemicals.

11.6.2. All work-related medical evaluations and examinations will be performed by Deweese Health Clinic during the normal work hours of 8 am until 5 pm.   Employees may seek a medical evaluation elsewhere.   Evaluations and examinations will be provided without cost to the employee, without loss of pay, and at a reasonable time and place.

11.6.3. Any laboratory employee or student worker who exhibits signs and symptoms of adverse health effects from work-related exposure should file a Report of Injury  to EHS.   At the sign or symptoms of exposure, the student should seek medical treatment from the Deweese Health Clinic or University Hospitals in Ravenna.

11.6.4. Information to Provide to the Clinician

At the time of the medical evaluation, the following information shall be provided:

• Personal information such as age, weight and University employee ID number;
• Common and/or IUPAC name of the hazardous chemicals to which the individual may have been exposed;
• A description of the conditions under which the exposure occurred;
• Quantitative exposure data, if available;
• A description of the signs and symptoms of exposure that the employee is experiencing, if any;
• A copy of the Safety Data Sheet (SDS) of the hazardous chemical in question;
• History of exposure including previous employment and non-occupational (recreational) hobbies; and
• Any additional information helpful in assessing or treating an exposure or injury such as a biological component of exposure or existence of an antitoxin.

11.6.5. Physician’s Written Opinion

For evaluation or examinations required by OSHA, the employer shall receive a written opinion from the examining physician which shall include the following:

• Recommendation for further medical follow-up;
• Results of the medical examination and any associated tests, if requested by the employee;
• Any medical condition which may be revealed during the examination which may place the employee at increased risk because of exposure to a hazardous chemical found in the workplace; and
• A statement that the employee has been informed by the physician of the results of the consultation or medical examination and any medical condition that may require further examination or treatment.
• Confidentiality & Individual’s Access to Personal Medical Records

11.6.6. All patient medical information is protected by Ohio and federal law and is considered strictly confidential. The medical facility is prohibited from disclosing any patient medical information not directly related to the work-related exposure under evaluation and should not reveal any diagnosis unrelated to exposure. Any patient information disclosed by the medical facility to the employee’s supervisor will be limited to information necessary in assessing an employee’s return to work, including recommended restrictions in work activities, if any. Any patient information disclosed by the medical facility to EHS will be limited to information necessary to develop a course of exposure monitoring, or perform hazard assessments and incident investigations, if appropriate, the medical facility will otherwise disclose patient medical information only as required by Ohio and Federal law, such as for Worker’s Compensation Insurance claims. Each employee has the right to access their own personal medical and exposure records. The medical facility will provide an employee with a copy of their medical records upon written request.

11.7. Medical Surveillance

11.7.1. Medical surveillance is the process of using medical examinations, questionnaires and/or biological monitoring to determine potential changes in health because of exposure to a hazardous chemical or other hazards. Certain OSHA standards require clinical examination as part of medical surveillance when exposure monitoring exceeds an established Action Level or PEL.

11.7.2. Kent State uses the Deweese Health Clinic for medical surveillance. Medical surveillance is required of employees routinely exposed to certain hazards as part of their job description (such as silica) and may be offered to other employees based on quantifiable or measured exposure.  Examples of hazards that are monitored through the medical surveillance program may include: Asbestos, Beryllium, Formaldehyde, Lead, Methylene Chloride, Noise (Hearing Conservation Program), Radioactive Chemicals (Bioassay Program), Respirator Use (Respirator Protection Program), Silica (Respirable Silica Program), and other particularly hazardous substances. Individuals with questions regarding work-related medical surveillance are encouraged to contact EHS for more information.

Section 12:  Hazardous Waste Management

12.1 Regulatory Requirements

12.1.1. In Ohio, hazardous waste is regulated by the Ohio EPA.

12.1.2.  Federal EPA regulations also govern certain aspects of hazardous waste management, since some of our waste is treated and disposed of out of state.

12.1.3.  These hazardous waste regulations are part of the Resource Conservation and Recovery Act, or RCRA. Local enforcement authority is administered by the Kent City Health Department.

12.2 Hazardous Waste Program

12.2.1. The EHS Hazardous Waste Program manages the shipment and disposal of all hazardous waste generated on campus. 

12.2.2.  Each laboratory employee must comply with the campus Hazardous Waste Management Program requirements and all applicable regulations. Hazardous waste pick up service is provided to all hazardous waste generators in research buildings on campus, as well as to regional campuses. 

12.2.3.Laboratory personnel are responsible for identifying hazardous waste, segregating, labeling, and storing it properly in the laboratory. 

12.2.4. Laboratory clean-outs and disposal of high hazard compounds must be scheduled at least 4 weeks in advance.  The PI/Laboratory Supervisor is responsible for coordinating the disposal of all hazardous materials from his/her/their laboratories prior to closing down laboratory operations.  Review the Laboratory  Clearance document for more information.  This can be found in the Appendix.

12.3. Definition of Hazardous Waste

12.3.1. Federal and State regulations define hazardous waste as a substance which poses a hazard to human health or the environment when improperly managed. A chemical waste is considered hazardous if it is either listed on one of the lists found in Federal or State regulations or if it exhibits one or more of the four following characteristics:

1. Ignitable - ignitable wastes generally are liquids with a flash point below 60°C or 140°F (however, just because a material has a higher flash point, it still cannot be drain disposed).
2. Corrosive - corrosive wastes are generally aqueous wastes with a pH less than or equal to two (2) or greater than or equal to (12.5). Solutions with a pH out of this range can be hazardous. Please contact EHS for clarification.
3. Reactive - reactive wastes are those wastes that are unstable, explosive, and capable of detonation or react violently with water.
4. Toxic - a chemical that poses a hazard to health or the environment
   • Has an acute oral LD50 less than 2,500 mg/kg
   • Has an acute dermal LD50 less than 4,300 mg/kg
   • Has an acute inhalation LC50 less than 10,000 ppm as a gas or vapor
   • Has an acute aquatic 96-hour LC50 less than 500 mg/L
   • Has been shown through experience or testing to pose a hazard to human health or environment because of its ability to cause cancer or mutation (carcinogen, mutagen, teratogen), acute toxicity, chronic toxicity, bio-accumulative properties, or persistence in the environment

12.3.2. The EPA definition of hazardous waste also extends to the following items:

• Abandoned chemicals
• Unused or unwanted chemicals
• Chemicals in deteriorating containers
• Empty containers that have visible residues
• Containers with conflicting labels
• Unlabeled or unknown chemicals

12.3.3. Chemicals not in frequent use must be carefully managed to prevent them from being considered a hazardous waste.  This is especially true for certain compounds that degrade and destabilize over time and require careful management so that they do not become a safety hazard.  Be cautious of substances that are corrosive or reactive.  If there is any degradation of the bottle, disposal should occur.

12.4. Extremely Hazardous Waste

Certain compounds meet an additional definition known as “extremely hazardous waste”. This list of compounds includes carcinogens, pesticides, and reactive compounds, among others (e.g., formaldehyde, chloroform, and hydrofluoric acid). The Federal EPA refers to this waste as “acutely hazardous waste”, but EPA has published a more detailed list of extremely hazardous waste. Both the State and the Federal lists are included in the EHS list of extremely hazardous waste. NOTE: While there is some overlap with the list of Particularly Hazardous Substances, the extremely hazardous waste list is specific to hazardous waste management.

12.5 Proper Hazardous Waste Management

12.5. Training

All personnel who handle, manage, or dispose of hazardous waste must complete training prior to working with these materials. The EHS online Hazardous Materials and Waste Management training course covers the hazardous waste program requirements and includes training on container labeling. To complete the Waste Management training, log into. This training is required every three years.

12.6. Waste Identification

All the chemical constituents in each hazardous waste stream must be accurately identified by knowledgeable laboratory personnel. This is a critical safety issue for both laboratory employees that handle the waste once it is turned over to EHS. Mixing of incompatible waste streams has the potential to create violent reactions and is a common cause of laboratory accidents.  If there is uncertainty about the composition of a waste stream resulting from an experimental process, laboratory workers must consult the PI/Laboratory Supervisor or the Chemical Hygiene Officer.  In most cases, careful documentation and review of all chemical products used in the experimental protocol will result in accurate waste stream characterization.
   
The manufacturer’s SDS provides detailed information on each hazardous ingredient in laboratory reagents and other chemical products, and also the chemical, physical, and toxicological properties of that ingredient.  The SDS library provides an extensive library of research chemicals.  Waste streams that have a large percentage of ingredients listed as proprietary information should be discussed with EHS.

12.7. Labeling

Hazardous waste labels must be placed on the hazardous waste container upon the start of accumulation. �鶹��ý utilizes the CEMS system for submitting hazardous waste pickup requests.  Each label must be completed accurately and updated as the contents of the waste container change. Product names or abbreviations for waste container ingredients should not be used. Information on how to use CEMS is available on the EHS website under .

12.8. Waste Tracking System UNH CEMS

1. Go to . Select Login button under the Welcome Guest Profile.
2. Select KSU Single Sign On and Login with KSU Flashline Credentials.
3. Select Hazardous Waste Dashboard and then select request waste removal
4. Fill in the department, location, waste name, storage state,  quantity and comments (optional). Save the request.  If you want an email confirmation of the submission (select the box).

12.9. Storage

Waste generated from Smith, Science Research Building (SRB) and Williams Hall labs are to be stored in the hazardous waste storage room in the basement of Williams Hall near the loading dock.

Waste generated from Cunningham Hall and Cunningham Annex labs are to be stored in the Waste Storage Room in the Cunningham Annex (A013) basement.

Wastes from the Liquid Crystal Institute (LCI) building, Centennial Park, Lowry Hall, McGilvrey Hall and the Aeronautics and Technology Building (ATB), Center for the visual Arts (CVA) and Art Building are to be kept in the generating lab until picked up by the waste hauler.

Unknown waste presents a significant hazard due to the unknown composition and characteristics. They also cost the University additional monies to dispose of because they must be analyzed to determine their contents which is why the university emphasizes labeling of all containers with the name of the substances to avoid this situation.

12.10. Satellite Accumulation Area Requirements

A satellite accumulation area (SAA) is a term that refers to the storage location of hazardous waste at another location that is either at or near the point of hazardous waste generation which is owned and operated by the generator of the hazardous waste. Satellite accumulation areas are regulated under the Environmental Protection Agency (EPA) and the Resource Conservation and Recovery Act (RCRA) hazardous waste management program.

Satellite Accumulation Area Rules and Responsibilities

1. All waste must be labeled with the designation “HAZARDOUS WASTE”.
2. The Accumulation Date Field on the label must be filled in as soon as any waste is added to the container.
3. All containers must be labeled with contents.
4. Do not mix incompatible materials in containers. Storage containers must be separated by a partition or wall.
5. There should never be more than 55 gallons of hazardous waste allowed to accumulate in any satellite accumulation area.
6. Hazardous waste should never be poured down drains or sinks.
7. Hazardous waste should never be stored over drains or in sinks.
8. Hazardous waste must be stored in the immediate vicinity of the laboratory or work area . The hazardous waste storage location should always be clean and inspected on a routine basis.
9. Hazardous waste should not be stored with facility chemicals. Only compatible hazardous waste is permitted to be stored together in the same containers as waste accumulates.
10. Transfer full hazardous waste containers to permanent waste storage room.
11. Waste from discontinued projects, experiments, cleanouts and storage areas should always be transferred to the permanent waste storage area. Note: For large scale cleanouts (ex. laboratories) prior arrangements must be made with the EHS.

The hazardous waste storage area in each laboratory is considered a Satellite Accumulation Area (SAA). According to EPA requirements, this area must remain under the control of the persons producing the waste.  This means that it should be in an area that is supervised and is not accessible to the public.  Other SAA requirements include:

• Hazardous waste containers must be always labeled with a Waste tag.
• Waste must be collected and stored at or near the point of generation.
• The maximum amount of waste that can be stored in a SAA is 55 gallons of a hazardous waste or 1 quart of acutely/extremely hazardous waste. If you reach these volumes for acutely/extremely hazardous waste, you must have the waste removed within 3 days of reaching these set volumes.
• All hazardous waste containers in the laboratory must be kept closed when not in use, unless temporary venting of a container is necessary or to prevent dangerous situations, for instance buildup of extreme pressure.       Self venting caps can also be used in this case.
• Hazardous waste streams must have compatible constituents and must be compatible with the containers in which they are stored.
• Hazardous waste containers should be stored in secondary containment.
• Containers must be in good condition with leakproof lids.
• Containers should have 1 to 2 inches of headspace in each container.   Do not overfill.
• Dry wastes must be double-bagged in clear, 3-mil plastic bags
• Do not dispose of chemicals by pouring them down the drain or placing them in the trash.

12.11. Segregation

All hazardous materials must be managed in a manner that prevents spills and uncontrolled reactions. Stored chemicals and waste should be segregated by hazard class. Examples of proper segregation are:

• Segregate acids from bases
• Segregate oxidizers from organics
• Segregate cyanides from acids
• Segregate solids from liquids

Segregation of waste streams should be conducted in a similar manner to segregation of chemical products.

12.12. Incompatible Waste Streams

Mixing incompatible waste streams or selecting a container that is not compatible with its contents, is a common cause of accidents in laboratories and waste storage facilities.  Reactive mixtures can rupture containers and explode, resulting in serious injury and property damage.  All chemical constituents and their waste byproducts must be compatible for each waste container generated.  Waste tags must be immediately updated when a new constituent is added to a mixed waste container, so that others in the laboratory will be aware and manage it accordingly.

Some common incompatible waste streams include:

• Oxidizers added to any fuel can create an exothermic reaction and explode.  The most frequent is acids oxidizing flammable liquids.  For this reason, all flammable liquids are pH tested before they are consolidated.
• Piranha etch solution is a specific waste stream that contains sulfuric acid and hydrogen peroxide, which form a reactive mixture that is often still fuming during disposal.  For this waste stream, and other reactive mixtures like it, vented caps are mandatory.
  • Use poly-coated bottles for these types of waste streams

12.13. Wastes That Require Special Handling

Unlabeled chemical containers and unknown/unlabeled wastes are considered unknowns, and additional fees must be paid to have these materials analyzed and identified.  These containers must be labeled with the word “unknown”.  To help prevent this, label all your products and use a Waste label as soon as one drop of waste is placed into a container.

Peroxide Forming Chemicals 
Peroxide forming chemicals, or PFCs, include substances that can react with air, moisture or product impurities and undergo a change in their chemical composition during normal storage.  The peroxides that form are highly reactive and can explode upon shock or spark.  Peroxides are not particularly volatile and thus tend to precipitate out of liquid solutions. It is dangerous to allow a container of these materials to evaporate to dryness, leaving peroxide crystals on the container's surfaces.

Each container of peroxide forming chemicals should be dated with the date received and the date first opened. There are three classes of peroxide forming chemicals, with each class having different management guidelines. A review of the safety information provided by the manufacturer can be used as a guide to managing PFCs.

Ensure containers of PFCs are kept tightly sealed to avoid unnecessary evaporation, as this inhibits the stabilizers that are sometimes added.  Visually inspect containers periodically to ensure that they are free of exterior contamination or crystallization. PFC containers must be disposed of prior to expiration date. If old containers of peroxide forming chemicals are discovered in the laboratory, (greater than two years past the expiration date or if the date of the container is unknown), do not handle the container.  If crystallization is present in or on the exterior of a container, do not handle the container. Secure it and contact the EHS.

Dry Picric Acid 
Picric acid (also known as trinitrophenol) must be kept hydrated at all times, as it becomes increasingly unstable as it loses water content.  When dehydrated, it is not only explosive but also sensitive to shock, heat and friction. Picric acid is highly reactive with a wide variety of compounds (including many metals) and is extremely susceptible to the formation of picrate salts.  Be sure to label all containers that contain picric acid with the date received, and then monitor the water content every 6 months.  Add distilled water as needed to maintain a consistent liquid volume.  
If old or previously unaccounted for bottles of picric acid are discovered, do not touch the container. Depending on how long the bottle has been abandoned and the state of the product inside, even a minor disturbance could be dangerous.  Visually inspect the contents of the bottle without moving it to evaluate its water content and look for signs of crystallization inside the bottle and around the lid.  If there is even the slightest indication of crystallization, signs of evaporation, or the formation of solids in the bottle, do not handle the container and contact EHS immediately.  Secure the area and restrict access to the container until it can be evaluated by EHS personnel.  

Explosives and Compounds with Shipping Restrictions

A variety of other compounds that are classified as explosives or are water or air reactive are used in research laboratories. These compounds often have shipping restrictions and special packaging requirements.  When disposing of these compounds, employees must ensure that they are stored appropriately for transport.  Flammable metals must be completely submerged in oil before they are brought to a waste pick-up. Many pyrophoric and reactive compounds can be stabilized using a quenching procedure prior to disposal.  Chemicals classified by the Department of Transportation (DOT) as explosives (e.g., many nitro- and azo- compounds) will require special packaging and shipping and may require stabilization prior to disposal.  Consult EHS at for disposal considerations of these compounds.

12.14. Managing Empty Containers

Empty containers that held Extremely Hazardous waste must be managed as hazardous waste.  Do not rinse or reuse these containers.

All other hazardous waste containers must be empty as much as possible before disposal.   The containers can be reused or discarded as appropriate.    The labels should be completely defaced (remove it or mark it out completely).   EHS has developed a fact sheet as guidance for the handling of empty containers.

12.15. Transportation

It is a violation of DOT regulations to transport hazardous waste in personal vehicles, or to carry hazardous waste across campus streets that are open to the public.  There are two accumulation points on campus.  One is in Williams Hall and the other Cunningham Annex.  Waste can be transported on a cart to these locations.

The transportation of hazardous waste between buildings, rooms on campus or through hallways and other public spaces always poses a risk of accidental release or exposure. To minimize the risk of harm to faculty, staff, students, visitors and the environment the following guidelines listed below will be used for transporting hazardous waste by University personnel, visitors or students. Contact EHS if there are any questions.

• ALL waste containers have a proper "HAZARDOUS WASTE".  Label with Initial Accumulation Date.
• ALL contents are listed. List the pH on the disposal tag.
• The bottle or jar has a cap that fits tightly.
• There are no old or extraneous labels on the container.
• There is at least 1" to 2" of head space in liquid containers to allow for expansion and reduce the potential for spillage.
• The outside of the bottle is clean and dry.
• Use secondary containers or utility service carts to transport waste to designated areas.

Note: If transporting individual waste bottles outside of the laboratory always use secondary containment (Ex. Plastic Paint or Nalgene Buckets with secure lids, Rubber Bottle Carrier or Original Shipping Containers).

If transporting multiple, large or heavy containers use a utility service cart with large wheels that are 4 to 6 inches in diameter and have a chemical resistant tray or surface and 3-inch lips on all sides to keep chemicals from sliding off the cart.

Always wear the appropriate personal protective equipment (PPE) for the chemicals being transported in the event of a spill or splash to the skin or eyes.

12.17. Accumulation and Disposal

Frequent disposal will ensure that hazardous waste accumulation areas in labs are managed properly, and that accumulation limits are not exceeded.   Hazardous chemical waste can be stored in a laboratory for up to 180 days.  Once a waste container is 80% full or it is near the 180-day time limit, it should be transported to the waste rooms in Williams Hall or Cunningham Annex.  

12.18. Hazardous Waste Minimization

�鶹��ý is a small  quantity generator of hazardous waste. To reduce the amount of chemicals that become waste, administrative and operational waste minimization controls can be implemented. Usage of chemicals in laboratory areas should be reviewed to identify practices which can be modified to reduce the amount of hazardous waste generated. To minimize the costs, health hazards, and environmental impacts associated with the disposal of hazardous waste, below are some guidelines regarding waste minimization:

Purchasing Control: Check the inventory UNH CEMS before new products are ordered.  When      ordering chemicals, be aware of any properties that may preclude long term storage, and order only exact volumes to be used. Using suppliers who can provide quick delivery of small   quantities can assist with reducing surplus chemical inventory.

Inventory Control: Rotate chemical stock to keep chemicals from becoming outdated. Identify surplus/unused chemicals and attempt to redistribute these to other users.

Operational Controls: Review your experimental protocol to ensure that chemical usage is  minimized. Reduce total volumes used in experiments; employ small scale procedures when  possible.  Instead of wet chemical techniques, use instrumental methods, as these generally  require smaller quantities of chemicals.  Evaluate the costs and benefits of off-site analytical services. Avoid mixing hazardous and non-hazardous waste streams.  Use less hazardous or non-hazardous substitutes when feasible.  Some examples include:

• Specialty detergents can be substituted for sulfuric acid/chromic acid cleaning solutions  
• Gel Green and Gel Red are recommended in place of ethidium bromide

12.19. Drain Disposal

Kent State does not permit drain disposal of chemical wastes, unless a specific dilution and/or neutralization method for a consistent waste stream has been reviewed and approved by EHS.  Drain disposal of properly disinfected infectious or biohazardous liquids is acceptable, if disinfection is conducted as specified by the EHS Biosafety Program, and the liquids disposed contain no other hazardous constituents.

12.20. Bench Top Treatment

EPA regulations allow some limited bench top treatment of certain chemical waste streams in laboratories, provided that specific procedures are followed. Due to the stringent nature of these requirements, any treatment of hazardous waste in labs must be reviewed and approved by EHS.  

13.  Accidents, Emergencies, and Chemical Spills

13.1 Overview

Laboratory emergencies may result from a variety of factors, including serious injuries, fires and explosions, spills and exposures, and natural disasters. All laboratory employees should be familiar with and aware of the location of their laboratory’s emergency response plans and safety manuals. Before beginning any laboratory task, know what to do in the event of an emergency situation. Identify the location of safety equipment, including first aid kits, eye washes, safety showers, fire extinguishers, fire alarm pull stations, and spill kits. Plan ahead and know the location of the closest fire alarms, exits, and telephones in your laboratory.

For all incidents requiring emergency response, call the police at 911.

13.2 Medical Emergencies

13.2.1 In the event of any medical emergency:

Check the scene to see that it is safe and that you and the victim are not in danger.

Call the Kent State Police by dialing 9-1-1 from a campus phone and give the following information:

• The location of the incident
• The type of injury or incident
• If the victim is conscious or unconscious
• If an ambulance is needed

13.2.2 If the injury is severe enough to be an emergency, do not leave the scene or attempt to move the injured person from the scene. Moving the injured person from where Kent State PD knows the person to be can delay care and worsen outcomes.

13.2.3 Get first aid kit and use as directed or to the level of your first aid training.

13.2.4 If injury came from chemical exposure or there is a potential for chemical exposure, wear appropriate PPE and do not expose yourself while assisting.

13.2.5 Do not move the victim if unsure about a head or neck injury.

13.2.6 If someone has a foreign object lodged in them, do not remove it.

13.2.7 If there is a chemical exposure as well as an injury, if the person can move themselves to wash the area at the sink or eyewash, have them do so.

13.2.8 Remain calm and reassure the victim while waiting for emergency personnel.

13.2.9 Once the area is secured and the scene/victim has been transferred to emergency responder care, notify the PI/Supervisor and report the injury to EHS using the “Report an Incident or Safety Concern” tool on the EHS main page. The campus has a requirement to report work related serious injuries to PERRP within 8 hours of the incident occurring, so the prompt reporting of the incident and relevant details is vital for EHS to follow up.

13.2.10 Accidents/Injuries that are not Medical Emergencies

PI/Laboratory Supervisors are responsible for ensuring that their employees receive appropriate medical attention in the event of an occupational injury or illness. Local medical treatment facilities can be found at the Deweese Health Clinic or UH in Ravenna. All accidents and near misses must be reported to the supervisor and EHS. An injury, incident or safety concern can also be reported to EHS online.  EHS will conduct an accident investigation and develop recommendations and corrective actions to prevent future accidents.  At a minimum, each laboratory must have the following preparations in place:

• Fully stocked first aid kit
• Posting of emergency telephone numbers and locations of emergency treatment facilities
• Training of staff to accompany injured personnel to medical treatment site and to provide medical personnel with copies of SDS(s) for the chemical(s) involved in the incident

13.3. Laboratory Safety Rules

13.3.1  Familiarize yourself with the lab, location and operation of the safety features (exits, fire extinguishers, safety showers, eye wash facility, and first aid and spill kits).

13.3.2 Complete training  in Flashtrain on all aspects of lab safety relevant to your work prior to beginning potentially hazardous activities and when changes are made to the procedures.

13.3.3 Wear appropriate Personal Protective Equipment (PPE), such as: approved gloves, safety glasses or goggles, lab coat or apron, long pants that cover your ankles, and closed-toe shoes that cover your entire foot. PPE requirements will be designated by the hazards associated with the lab space.

13.3.4 Work in properly-ventilated areas and in a safe manner according to any relevant Standard Operating Procedures.

13.3.5 Do not eat, drink, chew gum, smoke, or apply makeup while working in laboratory spaces where chemical, radioactive, or biological hazards are present.

13.3.6 Store all chemicals and other hazardous materials according to prudent practices  and Kent State  policy. Know your chemical compatibilities/incompatibilities, stability, shelf life and recommended storage conditions.

13.3.6 Dispose of all waste in the correct manner in accordance with Kent State policy. There are specific protocols for chemicals, contaminated and broken glass and plastic, sharps, radioactive isotopes and biological agents. Refer to Lab Safety Manuals for additional information on working with hazardous materials in the lab.

13.3.7 Know how to respond properly in an emergency. Clean up all spills safely and promptly, and report them to the Lab supervisor. If unsure how to safely clean up a spill, ask PI/ Lab Supervisor or EHS for assistance.

13.3.8 Report to Lab Supervisor and EHS of all incidents (spills, splashes, fires, etc.), injuries, and accidents, right away, even if the incident seems small or unimportant.

13.3.9  Report to PI/Lab Supervisor of any unsafe conditions in the laboratory as soon as possible.

13.3.10 If an employee has a severe or life threatening injury, call for emergency response at 911. Employees with minor injuries should be treated with first aid kits as appropriate(by those with proper training), and sent to the appropriate facility for further evaluation and treatment. The Deweese Health Clinic is open during normal business hours from 8AM until 5 PM.   After normal business hours, treatment can be obtained at UH Hospitals in Ravenna.

13.3.11 Serious occupational injuries, illnesses, and exposures to hazardous substances must be reported to the supervisor and EHS within 8 hours. EHS will report the event to PERPP, investigate the accident, and complete exposure monitoring, if necessary. Serious injuries include those that result in permanent impairment or disfigurement, or require hospitalization. Examples include amputations, lacerations with severe bleeding, burns, concussions, fractures and crush injuries. As soon as Faculty/ Laboratory Supervisors are aware of a potentially serious incident, they must contact EHS.   

13.4. Fire-Related Emergencies

If you encounter a fire, or a fire-related emergency (e.g., abnormal heating, smoke, burning odor), immediately follow these instructions:

1. Pull the fire alarm pull station and call 911 to notify the �鶹��ý Police Department.
2. Evacuate and isolate the area
3. Use portable fire extinguishers to facilitate evacuation and/or control a small fire (i.e., size of a small trash can), if safe to do so.
4. If possible, shut off equipment before leaving
5. Close doors and/or fume hood sash
6. Remain safely outside the affected area to provide details to emergency responders; and
7. Evacuate the building when the alarm sounds.  It is against state law to remain in the building when the alarm is sounding.  If the alarm sounds due to a false alarm or drill, you will be allowed to re-enter the building as soon as the Fire Department determines that it is safe to do so. Do not go back into the building until the alarm stops and you are cleared to reenter.
8. If your clothing catches on fire, go to the nearest emergency shower immediately.  If a shower is not immediately available, then stop, drop, and roll. A fire extinguisher may be used to extinguish a fire on someone’s person as last resort. Report any burn injuries to the supervisor immediately and seek medical treatment.  Report to EHS within 8 hours every time a fire extinguisher is discharged. The fire extinguisher will also need to be replaced.

13.5 Chemical Spills

Chemical spills can result in chemical exposures and contaminations. Chemical spills become emergencies when:

13.5.1. The spill results in a release to the environment (e.g., sink or floor drain)

13.5.2 The material or its hazards are unknown

13.5.3 Laboratory staff cannot safety manage the hazard because the material is too hazardous or the quantity is too large

13.5.6 Effective emergency response to these situations is imperative to mitigate or minimize adverse reactions when chemical incidents occur.

13.5.7 Factors to Consider before Spill Clean-Up

• Size of spill area
• Quantity of chemical
• Toxicity
• Volatility
• Clean up materials available
• Training of responders

13.5.8 In the event of a significant chemical exposure or contamination, immediately try to remove or isolate the chemical if safe to do so. When skin or eye exposures occur, remove contaminated clothing and flush the affected area using an eye wash or shower for at least 15 minutes. If a chemical is ingested, follow the instructions on the SDS. Obtain medical assistance as indicated. Remember to wear appropriate PPE before helping others. Faculty/Laboratory Supervisors must review all exposure situations, make sure affected employees receive appropriate medical treatment and/or assessment, and arrange for containment and clean-up of the chemical as appropriate.

13.5.9 Small chemical spills can be cleaned up by laboratory personnel who have been trained in spill clean-up and with the appropriate materials.  A small spill is generally defined as < 1 liter of chemical that is not highly toxic, does not present a significant fire or environmental hazard, and is not in a public area such as a common hallway.  Large chemical spills include spills of larger quantities, spills of any quantity of highly toxic chemicals, or chemicals in public areas or adjacent to drains. Large spills require emergency response. Call 911 for assistance.

13.6. What to do with a Small Chemical Spill (<1 Liter)

1. Evacuate all non-essential persons from the spill area
2. If needed, call for medical assistance by dialing 911
3. Help anyone who may have been contaminated. Use emergency eyewashes/showers to flush the skin or eyes for at least 15 minutes
4. Post someone just outside the spill area to keep people from entering. Avoid walking through contaminated areas
5. You must have the proper protective equipment and clean-up materials to clean-up spills. Check the chemical's Safety Data Sheet (SDS) in your laboratory or online in the CEMS database.
6. Turn off sources of flames, electrical heaters, and other electrical apparatus, and close valves on gas cylinders if the chemical is flammable (stop ongoing processes if necessary)
7. Confine the spill to a small area. Do not let it spread
8. Avoid breathing vapors from the spill. If the spill is in a non-ventilated area (confined space), do not attempt to clean it up. Call for emergency personnel to respond and clean up the spill
9. Wear personal protective equipment, including safety goggles, gloves, and a laboratory coat or other protective garment to clean-up the spill (consult with SDS)
10. Work with another person to clean-up the spill. Do not clean-up a spill alone
11. DO NOT ADD WATER TO THE SPILL
12. Replenish supplies after a spill.

13.6.12 Use an appropriate kit to neutralize and absorb inorganic acids and bases. For other chemicals, use the appropriate kit or absorb the spill with sorbent pads, paper towels, vermiculite, dry sand, or diatomaceous earth. For mercury spills and for all other spills requiring specialized clean-up procedures, contact EHS. Collect the residue and place it in a clear plastic bag. Double bag the waste and label the bag with the contents and label it to be picked up as chemical waste.

13.7.  What to do with a Large Chemical Spill (>1 Liter)

Large chemical spills require emergency response. Call 911.  If the spill presents a situation that is immediately dangerous to life or health (IDLH) or presents a significant fire risk, activate a fire alarm, evacuate the area, and wait for emergency response to arrive.

1. Remove the injured and/or contaminated person(s) and provide first aid
2. Call for emergency medical response/medical assistance by dialing 911
3. Help anyone who may have been contaminated. User emergency eyewash/showers by flushing the skin or eyes for at least 15 minutes
4. As you evacuate the laboratory, close the door behind you, and:
5. Post someone safely outside and away from the spill area to keep people from entering
6. Confine the spill area if possible and safe to do so                   
7. Leave on exhaust ventilation
8. If possible, turn off all sources of flames, electrical heaters, and other electrical equipment if  the spilled material is flammable
9. Avoid walking through contaminated areas or breathing vapors of the spilled material
10. Any employee with known contact with a particularly hazardous chemical must shower, including washing of the hair as soon as possible unless contraindicated by physical injuries
11. Replenish supplies after a spill.

13.8.  Highly Toxic Chemical Spills

Do not clean up by yourself! All spills of these chemicals require emergency response:

• Aromatic amines
• Hydrazine
• Bromines
• Nitriles
• Carbon disulfide
• Nitro-compounds
• Cyanides
• Organic halides

13.9.  Other hazards from spills

• Biological hazard
• Radioactive hazard(See radiation safety plan)
• Consult EHS in the event of either of these issues.   Please also refer to the Radiation safety manual and biosafety manual.

14. Lab Audits and Compliance

14.1 Regulatory Requirements

14.1.1 Implementation of the necessary work practices, procedures, and policies outlined in this chapter is required by the following:

14.1.2 Applicable regulations include those promulgated by the U.S. Department of Labor including 29 CFR 1910.1450 “” (the “Laboratory Standard”).

14.2 Laboratory Safety Audits

14.2.1 EHS has a comprehensive laboratory safety audit program to assist laboratories and other facilities that use, handle or store hazardous chemicals to maintain a safe work environment. This program helps to ensure compliance with regulations and to fulfill Kent State’s commitment to protecting the health and safety of the campus community.

14.2.2 As part of this laboratory safety program, EHS conducts periodic inspections of laboratories and other facilities with hazardous chemicals to ensure the laboratory is operating in a safe manner and to ensure compliance with all federal, state and university safety requirements. The primary goal of lab audits is to identify both existing and potential accident-causing hazards, actions, faulty operations and procedures that can be corrected before an accident occurs.  EHS will work with the Department Chair, Divisional Dean and University Administration to suspend or restrict any operation that “presents a significant imminent hazard associated with life safety, or the health and welfare of campus personnel or the public” until that hazardous condition or activity is abated.

14.2.3 The laboratory safety audit is comprehensive in nature and investigates all key aspects of working with hazardous chemicals.  While audits are a snapshot in time and cannot identify every accident-causing mistake, they do provide important information on the overall operation of a particular laboratory.   Laboratory audits categories include:

• Documentation and Training;
• Emergency and Safety Information;  
• Fire Safety;
• General Safety;
• Use of personal protective equipment (PPE);
• Housekeeping;
• Chemical Storage;
• Fume Hoods;  
• Chemical Waste Disposal and Transport;
• Mechanical and Electrical Safety.  

14.2.4. Once the audits are completed, EHS issues a Laboratory Audit Report via Flashtrain. The report identifies deficiencies in the laboratory, both critical and non-critical. Critical deficiencies are those that have the potential to lead to serious injuries or be of critical importance in the event of an emergency. These deficiencies must be immediately corrected. Non-critical deficiencies must be corrected within 30-days. Any deficiency that requires a “UFM Work Order” for completion should  be added to the Facilities Services Work Order system so that it can be expedited by University Facility Services(UFM). Lab personnel should know how to obtain a copy of the most recent Laboratory Audit Report.   For guidance on setting up a safe and successful lab, reference the PI and  Lab Supervisors Checklist.

14.3 Notification and Accountability

The laboratory audit program requires that Faculty/ Laboratory Supervisors and other responsible parties take appropriate and effective corrective action upon receipt of written notification of audit findings. Critical deficiencies are required to be corrected within 48 hours; non-critical deficiencies should be corrected within 30 days. Failure to take corrective actions within the required timeframe may result in an escalation of the notification to the Department Chair , Dean and Provost.  Depending on the severity of the deficiency, the EHS Director, in consultation with the Department Chair, Divisional Dean, and Provost, may temporarily suspend research activities until the violation is corrected. In some cases, the PI may be required to provide a corrective action plan to the EHS Director prior to resumption of research activities.  

14.4. Recordkeeping Requirements

Accurate recordkeeping demonstrates a commitment to the safety and health of the Kent State community, integrity of research, and protection of the environment. EHS is responsible for maintaining records of inspections, accident investigations, and training conducted by EHS staff.  Documentation of training conducted by EHS staff can be accessed via Flashtrain.  Departments or laboratories must document lab specific health and safety training, including safety meetings, one-on-one training, and classroom and online training.  Additionally, the following records must be retained in accordance with the requirements of state and federal regulations:

• Accident records – 30 years past the date of last employment
• Laboratory audit reports – 5 years
• Measurements taken to monitor employee exposures  over the Permissible exposure limit– 30 years past the date of last employment
• Chemical Hygiene Plan records should document that the facilities and precautions were compatible with current knowledge and regulations
• Inventory for Chemical substances
• Medical records must be retained in accordance with the requirements of state and federal regulations – duration of employment plus 30 year(Maintained by Deweese and Human Resources)
