Introduction -- What is a Chemical Hygiene Plan?

A chemical hygiene plan (CHP) is a written program stating the policies, procedures, and responsibilities that serve to protect employees from the physical and health hazards associated with the hazardous chemicals used in the laboratory.

Chemical Hygiene Plan Required Elements

  1. Defined standard operating procedures relevant to safety and health considerations for each activity involving the use of hazardous chemicals.
  2. Criteria to use to determine and implement control measures to reduce exposure to hazardous materials (i.e., engineering controls, the use of personal protective equipment, administrative controls, and hygiene practices) with particular attention given to the selection of control measures for extremely hazardous materials.
  3. A requirement to ensure laboratory chemical hoods and other protective equipment are installed and functioning properly.
  4. Information for persons working with hazardous substances specifying the hazards of the chemicals in the work area, the location of the CHP, signs and symptoms associated with hazardous chemical exposures, the permissible or recommended exposure limits of the chemicals, and the location and availability of information on the hazards, safe handling, storage, and disposal of hazardous chemicals [not limited to Material Safety Data Sheets (MSDSs)].
  5. Training for persons working with hazardous substances that includes methods and observations to detect the presence or release of a hazardous chemical, the physical and health hazards of the chemicals used, the measures to be taken to protect against these hazards (i.e., personal protective equipment, appropriate work practices, emergency response actions), and applicable details of the CHP.
  6. The circumstances under which a particular laboratory operation or procedure requires prior approval from the appropriate administrator.
  7. Requirements for medical consultation and medical examination whenever (1) a person develops signs or symptoms associated with a hazardous chemical, (2) exposure monitoring reveals an exposure level routinely above the action level, or (3) an event takes place in the work area such as a spill, leak, explosion or other occurrence resulting in the likelihood of a hazardous exposure.
  8. Designation of personnel responsible for the implementation of the CHP, including the assignment of a Chemical Hygiene Officer.
  9. Requirements for additional protection when working with particularly hazardous substances including "select carcinogens," reproductive toxins, and substances with a high degree of acute toxicity.
  10. Provisions for yearly re-evaluation of the CHP.

Other Suggested Elements of a Chemical Hygiene Plan

  1. Hazard identification including proper labeling of containers of hazardous chemicals and maintaining MSDSs in a readily accessible location.
  2. Requirements to establish and maintain accurate records monitoring employee exposures and any medical consultation and/or examinations, and to assure the confidentiality of these records.
