Regulatory
Heat Illness Prevention: What Changed in 2025
Safety People LLC·July 15, 2025·4 min read
The indoor heat illness standard (Cal/OSHA §3396) is now enforced alongside the long-standing outdoor standard (§3395). If your indoor work areas regularly exceed 82°F, the new rule applies.
Required elements: access to cool-down areas, drinking water, acclimatization for new workers, emergency response, and training in a language employees understand.
Don't forget the written plan. A verbal program is not compliant — Cal/OSHA inspectors will ask for the document.
Bilingual training is critical in California. We offer all heat illness training in English and Spanish, on-site or online.
