According to Cal/OSHA Section 3395, at what temperature threshold must employers implement their heat illness prevention procedures?
Correct Answer
A) 95°F
Cal/OSHA Section 3395 requires heat illness prevention procedures to be implemented when the temperature equals or exceeds 95°F.
Why This Is the Correct Answer
Option A is correct. Cal/OSHA Section 3395 mandates that employers activate their Heat Illness Prevention Plan procedures when the ambient temperature equals or exceeds 95°F. At this threshold, additional protective measures kick in including mandatory buddy systems, more frequent water and shade access, and enhanced supervisor monitoring.
Why the Other Options Are Wrong
Option B: 90°F
Option B is incorrect. 90°F is not the Cal/OSHA Section 3395 trigger for enhanced heat illness prevention procedures. At 90°F, general heat illness prevention practices (water, shade, rest) remain in effect, but the heightened 95°F procedures are not yet required.
Option C: 80°F
Option C is incorrect. 80°F is not a regulatory threshold under Section 3395 for implementing heat illness prevention procedures. While employers should always be mindful of worker comfort at 80°F, this temperature does not trigger the formal procedural requirements of Section 3395.
Option D: 85°F
Option D is incorrect. 85°F is not the Cal/OSHA trigger temperature. This value has no specific regulatory significance under Section 3395. The exam often includes plausible-sounding temperatures just below the correct threshold to test precise knowledge.
Memory Technique
Associate 95°F with 'High Heat' — '95 is where Cal/OSHA gets serious.' You can also remember it as: 95°F is the temperature where shade and water alone are not enough — you need a buddy system and supervisor oversight. Think '95 = Full Protocol.'
