The U.S. Occupational Safety and Health Administration (OSHA) passed its general industry lead regulations in 1978, but studies determined that workers, particularly in the construction industry, were still being overexposed to lead. In 1993, OSHA passed stricter regulations for the construction industry. Since then, several states, including California, have implemented their own OSHA-approved state regulations regarding lead exposure in the workplace. In California, this plan is commonly referred to as “Cal/OSHA,” and is administered by the California Department of Industrial Relations through the Division of Occupational Safety and Health (DOSH). Cal/OSHA covers all private sector workplaces, state government, and local government workplaces in the state. The Cal/OSHA lead regulations for the construction industry can be found in the California Code of Regulations, Title 8, 1532.1, or “8 CCR 1532.1” for short. This course focuses on the Cal/OSHA regulations for lead rather than on the federal regulations.
