29 CFR 1910.1450 - Occupational Exposure to Hazardous Chemicals in Laboratories

Who is covered:

The Laboratory Safety Standard applies to all laboratory employees working with chemicals (there is no "technically qualified individual" exemption under this standard). Laboratory employees may also need training according to other standards(e.g. MERTKA, Bloodborne Pathogens, NRC, etc.) if there are non-chemical hazards in the laboratory.

What training is required:

The Laboratory Safety Standard requires that laboratory employeesworking with chemicals receive training and information on the following topics:

  • The contents, location and availability of the Laboratory Safety Standard and its appendices;
  • The contents, location and availability of the Chemical Hygiene Plan;
  • Permissible Exposure Limits;
  • Signs and symptoms associated with exposures to the chemicals in the laboratory;
  • The location and availability of known reference materials (e.g. MSDSs etc.);
  • Methods and observations to detect the presence or release of chemicals in the laboratory;
  • The physical and health hazards of chemicals in the laboratory;
  • Measures employees can take to protect themselves from exposure to chemicals in the laboratory; and
  • Applicable details of the Chemical Hygiene Plan (including general and laboratory-specific Standard Operating Procedures).

When training is required:

Employees must be trained when hired, prior to assignments with new exposure potential, and at refresher intervals.

Record keeping:

Departments must establish and maintain records of training for at least five years from the date of training.
