Laboratory Chemical Safety

The Laboratory Standard, 1910.1450, protects employees who may be exposed during laboratory use of hazardous chemicals. A room called a lab does not automatically meet its scope. The employer must examine the actual work. Laboratory scale means containers can be safely handled by one person; it does not mean any small production batch qualifies.

The definition of laboratory use has four conditions. Work is on a laboratory scale, multiple chemicals or procedures are used, the procedures are not part of or simulations of production, and protective laboratory practices and equipment are available and commonly used. Production work in a laboratory may instead fall under the relevant chemical-specific standards. Uses with no potential employee exposure are also outside this rule’s scope.

Where the standard applies, its relationship to other Subpart Z health standards has exceptions. Applicable exposure limits remain in force, as do specified prohibitions on eye and skin contact. Certain monitoring and medical-surveillance duties apply when the stated conditions are met. Other applicable safety requirements are not erased by calling the work laboratory research.

This course provides general chemical-safety knowledge. It does not qualify a person for every experiment, designate a Chemical Hygiene Officer or provide biosafety, radiation, shipping or emergency-response qualifications. Appendix A offers non-mandatory guidance; it does not add duties by itself. The employer must provide training and controls for the actual lab, chemicals and tasks.
