Cal/OSHA Extreme Heat Notice

California’s Occupational Safety and Health Administration (Cal/OSHA) is urging all employers to protect workers from heat illness as high temperatures (exceeding 110°F) are forecast for the early part of July across California. 

When working in hotter conditions, workers must be closely observed for any signs of heat illness. In indoor workplaces, employers must correct unsafe conditions for workers created by heat as part of their Injury and Illness Prevention Program. Employers in California must take steps to protect outdoor workers from heat illness by providing water, rest, shade and training. 

Cal/OSHA’s heat illness prevention standard applies to all outdoor worksites. The agency’s Heat Illness Prevention in Indoor Places of Employment was approved on June 20, 2024 and is pending review by the Office of Administrative Law (OAL) which has 30 working days to review the proposal.  

See our discussion here for additional information on the proposed Indoor Heat Standard.
