The Occupational Safety and Health Administration (OSHA) was established within the Department of Labor in 1971. Its mission is "to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance" (OSHA web site).
Government Documents holds a partial collection of OSHA publications, including the following series:
Bulletins (L 35.3:)
Job safety and health quarterly (L 35.9/3:)
We also have a variety of general publications, pamphlets, and other OSHA materials, as well as laws, regulations, guidelines, training material, Congressional hearings, documents, and reports about occupational safety and health in the U.S.
