THE OSHA LABORATORY STANDARD
The basis for this standard (29 CFR 1910.1450) is a determination by the Occupational Safety and Health Administration (OSHA), after careful review of the complete rulemaking record, that laboratories typically differ from industrial operations in their use and handling of hazardous chemicals and that a different approach than that found in OSHA’s substance specific health standards is warranted to protect workers. The final standard applies to all laboratories that use hazardous chemicals in accordance with the definitions of laboratory use and laboratory scale provided in the standard. Generally, where this standard applies it supersedes the provisions of all standards in 29 CFR, part 1910, subpart Z, except in specific instances identified by this standard. For laboratories covered by this standard, the obligation to maintain employee exposures at or below the permissible limits (PELs) specified in 29 CFR, part 1910, subpart Z is retained. However, the manner in which this obligation is achieved will be determined by each employer through the formulation and implementation of a Chemical Hygiene Plan (CHP). The CHP must include the necessary work practices, procedures, and policies to ensure that employees are protected from all potentially hazardous chemicals in use in their work area. Hazardous chemicals as defined by the final standard include not only chemicals regulated in 29 CFR part 1910, subpart Z, but also any chemical meeting the definition of hazardous chemical with respect to health hazards as defined in OSHA’s Hazard Communication Standard, 29 CFR 1910.1200©.
Among other requirements, the final standard provides for employee training, medical consultation and examination (for over exposures), hazard identification, respirator use and record-keeping. To the extent possible, the standard allows a large measure of flexibility in compliance methods. (See Appendix A)
Effective Date: May 1, 1990
Compliance Date: Employers shall have completed an appropriate Chemical Hygiene Plan and commenced carrying out its provisions by January 31, 1991.
EMPLOYEES RIGHTS AND RESPONSIBILITIES
Employees have the right to be informed about the known physical and health hazards of the chemical substances in their work area and to be trained to work safely with these substances.
Employees have the right to file a complaint with OSHA if they feel they are being exposed to unsafe or unhealthful work conditions. Employees cannot be discharged, suspended, or otherwise discriminated against by their employer because of filing a complaint, or exercising their rights under the law.
Employees have the responsibility to attend training seminars on the Laboratory Safety Standard and Chemical Hygiene Plan and to stay informed about the chemicals in their work areas. They have the responsibility to use work practices and protective equipment required for safe performance of their job. Finally, they have the responsibility to inform their supervisors of conditions or work practices they believe to be a hazard to their health or to the health of others. Accidents must be reported to the supervisor.
HAZARDOUS CHEMICALS
The Laboratory Standard defines a hazardous chemical as any element, chemical compound, or mixture of elements and/or compounds which is a physical or health hazard.
A chemical is a physical hazard if there is scientifically valid evidence that it is a combustible liquid, a compressed gas, an explosive, a flammable, an organic peroxide, an oxidizer, pyrophoric, unstable material (reactive), or water reactive.
A chemical is a health hazard if there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees. Included are:
§ carcinogens
§ irritants
§ reproductive toxins
§ corrosives
§ sensitizers
§ radioactive material
§ neurotoxin (nerve)
§ biohazard
§ hepatotoxins (liver)
§ nephrotoxins (kidney)
§ agents that act on the hematopoietic system (blood)
§ agents that damage the lungs, skin, eyes, mucous membrances
A chemical is considered a carcinogen or potential carcinogen if it is so identified in any of the following:
§ National Toxicology Program, “Annual Report of Carcinogens” (latest edition)
§ International Agency for Research on Cancer, “Monographs” (latest edition)
§ OSHA, 29 CFR 1910, Subpart Z, Toxic and Hazardous Substances
A chemical is considered hazardous if it is listed in any of the following:
§ OSHA, 29 CFR 1910, Subpart Z, Toxic and Hazardous Substances
§ “Threshold Limit Values for Chemical Substances and Physical Agents in the Work Environment, “ ACGIH (latest edition)
§ The Registry of Toxic Effects of Chemical Substances,” NIOSH (latest edition)
In most cases, the label will indicate if the chemical is hazardous. Look for key words like caution, hazardous, toxic, dangerous, corrosive, irritant, carcinogen, etc. Old containers of hazardous chemicals (before 1985) may not contain hazard warnings.
If you are not sure a chemical you are using is hazardous, review the Material Safety Data Sheet (MSDS) or contact your supervisor, instructor, or the Office of Environmental Safety and Health (ESH).
MATERIAL SAFETY DATA SHEETS (MSDSs)
A Material Safety Data Sheet (MSDS) is a document containing chemical hazard and safe handling information and is prepared in accordance with the OSHA Hazard Communication Standard. An MSDS should be obtained for each chemical used in the laboratory.
Chemical manufacturers and distributors must provide the purchasers of hazardous chemicals an appropriate MSDS for each hazardous chemical/product purchased.
If an MSDS was not provided with the shipment of a hazardous chemical, one should be requested from the manufacturer or distributor in a timely manner. (See the “MSU Hazard Communication Program Summary and Compliance Manual” for a sample MSDS request letter).
The Office of Environmental Safety and Health (ESH), Facilities Management Building, extension 3481 is a central repository for MSDSs. If you want to review an MSDS, contact your supervisor, instructor, the chemical supplier, or ESH.
If your department does not have a copy of the “MSU Hazard Communication Program Summary and Compliance Manual” contact ESH at extension 3481.
CHEMICAL INVENTORIES
The OSHA Laboratory Standard does not require chemical inventories; however, the OSHA Hazard Communication Standard requires an inventory of all hazardous chemicals. An annual inventory maintained by each department or area can reduce the number of unknowns and the tendency to stockpile chemicals.

Murray State University
Chemical Hygiene Plan
The Chemical Hygiene Plan is a written plan to assist all laboratories at Murray State University using chemicals.
SCOPE AND APPLICATION
The CHP applies to all personnel at Murray State University and related facilities engaged in research activities and operations involving laboratory use of hazardous chemicals.
The CHP does not apply to:
1. Use of laboratory chemicals that do not meet the criterion of laboratory use.
2. Laboratory use of hazardous chemicals that provide no potential for employee exposure. Examples of such conditions might include:
a. Procedures using chemically-impregnated test media such as dip-and-read tests where a reagent strip is dipped into the specimen to be tested and the results are interpreted by comparing the color reaction to a color chart by the manufacturer of the test strip; and
b. Commercially prepared kits such as those used in performing pregnancy test in which all of the reagents needed to conduct the test are contained in the kit.
Laboratory uses of chemicals not covered by the CHP are subject to the full provisions of the OSHA Hazard Communication Standard and the Murray State University Right-to-Know Program. Contact the Office of Environmental Safety and Health within the Facilities Management Department for additional information.
RESPONSIBILITY
The Murray State University Office of Environmental Safety and Health within the Facilities Management Department and the Chemical Hygiene Officer will develop the provisions of the CHP.
The overall responsibility for all University operations lies with the President and their administrative staff. The president has designated the Office of Environmental Safety and Health as the operational subunit for overseeing compliance with all federal, state, and local regulations relating to chemical management.
The primary responsibility of the Office of Environmental Safety and Health (ESH) is to promote safe and proper chemical management at Murray State University. Chemical management includes, but is not limited to, the procurement and the safe handling, storage, use, and disposal of chemicals. The specific duties and responsibilities of ESH shall include, but are not limited to, the following:
§ Serve as consultant to administration, faculty, and staff (University Community) on matters related to chemical management.
§ Be cognizant of all applicable government and University policies, procedures, guidelines, laws, and regulations related to chemical management and transmit this information in appropriate form to the University Community.
§ Develop, review, and/or recommend procedures and guidelines, and to comply with applicable regulations.
§ Develop, review, and recommend programs of training in chemical management for the University Community.
§ Review conditions for compliance with government and/or University policies, procedures, guidelines, and regulations, and recommend appropriate corrective actions. In extreme circumstances, this may include suspension of the activity in question.
§ Keep a written record of activities, actions, decisions, and recommendations of ESH.
The Chemical Hygiene Officer (CHO) is responsible for developing generic Standard Operating Procedures (SOPs) when laboratory work requires the use of hazardous chemicals. The CHO may assign areas of responsibility to departments, department safety and health committees, laboratory supervisors, Designated Trained Individuals (DTIs), and other individuals as necessary, to implement and carry out the provisions of the CHP.
Department Heads are responsible for implementing and maintaining the CHP in their respective work areas. For more efficient implementation of the CHP, department heads should select one of more individuals to serve as coordinators. These coordinators are referred to as Designated Trained Individuals (DTIs). Department safety and health committees can also assume these responsibilities.
The Laboratory Supervisors are responsible for chemical hygiene in the laboratories. Their responsibilities include, but are not limited to the following:
§ Develop specific SOPs for each laboratory experiment requiring the use of hazardous chemicals.
§ Ensure that workers know and follow the chemical hygiene rules.
§ Ensure that appropriate training has been provided for specific hazards associated with the hazardous chemicals used.
§ Ensure that facilities are adequate for material being used.
§ Provide regular and formal chemical hygiene inspections of their facilities and equipment.
§ Determine the appropriate level of protective apparel and equipment; ensure that it is available and in working order; insure that training has been provided.
§ Inform all laboratory personnel of safety hazards and safety guidelines applicable to that laboratory.
§ Require adherence to guidelines relating to safe usage of approved apparatus and the acquisition, storage, and disposal of hazardous materials.
§ Be alert to and informed of all University, federal, state, and local regulations and policies relating to each particular laboratory operation.
§ Provide instructional opportunities in techniques and safety attitudes to new laboratory personnel, as well as to more experienced lab workers.
Laboratory workers are responsible for planning and conducting each operation in accordance with University chemical hygiene procedures and for developing good personal chemical hygiene habits. The most important rule for laboratory safety is that everyone involved in the operations, from the highest administrative level to the individual worker, must be aware of his or her individual safety responsibilities. All have a basic responsibility to themselves and to their co-workers to plan and execute all laboratory operations in a manner that will not be a hazard.
Students are not covered under the provisions of the OSHA Laboratory Standard. However, students should be made aware of chemical health and safety hazards in classroom situations and should be provided with information and equipment to protect themselves from those hazards. Departments should provide student training at the beginning of each course in which hazardous chemicals are used. Specific safety instructions should be provided at the beginning of each class period.
EXPOSURE LIMITS
For laboratory uses of hazardous substances, departments must assure that laboratory employees’ exposures to such substances do not exceed the permissible exposure limits (PELs) specified in 29 CFR 1910, subpart Z, or the published exposure limits, whichever is lower. If conditions create the possibility of an over exposure, contact ESH for technical assistance and evaluation to determine if monitoring is necessary. Monitoring will be done in accordance with ACGIH approved analytical methods.
