A construction crew is working in 89°F temperature with high humidity. According to Cal/OSHA heat illness prevention requirements, what must be provided?
Correct Answer
B) Water and shade readily available
Cal/OSHA Section 3395 requires that when temperatures reach 80°F or above, employers must provide water and shade that are readily accessible to all employees at all times.
Why This Is the Correct Answer
Cal/OSHA Section 3395 mandates that when temperatures reach 80°F or above, employers must provide both water and shade that are readily accessible to all employees at all times. At 89°F with high humidity, this requirement is clearly triggered. The regulation emphasizes 'readily available' meaning immediate access without having to request it, ensuring worker safety during heat exposure conditions.
Why the Other Options Are Wrong
Option A: Shade only when requested
This violates Cal/OSHA requirements because shade must be readily available at all times when temperatures reach 80°F or above, not just when requested. Workers shouldn't have to ask for basic heat illness prevention measures.
Option C: Mandatory 15-minute breaks every hour
While breaks are important for heat illness prevention, Cal/OSHA doesn't mandate specific 15-minute hourly breaks. The primary requirements are water and shade availability, with additional measures like rest periods being situational based on conditions.
Option D: Air conditioning in work areas
Cal/OSHA doesn't require air conditioning in outdoor work areas. The regulation focuses on practical measures like water and shade that can be implemented in construction environments where air conditioning isn't feasible.
