Chemical Safety in Laboratories

The Laboratory Standard (Occupational Exposure to Hazardous Chemicals in Laboratories) is found in the Washington Administrative Code, Part 296-62-400.

This regulation is designed to protect laboratory employees from over-exposure to chemicals. It requires the employer to:

  • Monitor laboratories for indications of over-exposure.
  • Provide medical consultation and examination for workers who may have been over-exposed.
  • Develop a written Chemical Hygiene Plan and appoint a chemical hygiene officer.
  • Designate specific laboratory areas for work with carcinogens, mutagens, teratogens or highly toxic substances.
  • Provide training programs.
  • Ensure that labels on chemicals are maintained.
  • Ensure that Material Safety Data Sheets (MSDSs) are readily accessible.
