Calculate the minimum shade area required for 8 construction workers during a heat illness prevention cool-down period in California:
Correct Answer
C) 40 square feet
Cal/OSHA Section 3395 requires a minimum of 5 square feet of shade per person. For 8 workers: 8 × 5 = 40 square feet minimum.
Why This Is the Correct Answer
Cal/OSHA Section 3395 mandates a minimum of 5 square feet of shade per person during heat illness prevention cool-down periods. For 8 construction workers, the calculation is straightforward: 8 workers × 5 square feet per worker = 40 square feet. This regulation ensures adequate space for workers to rest and cool down effectively during hot weather conditions, preventing heat-related illnesses on construction sites.
Why the Other Options Are Wrong
Option A: 48 square feet
48 square feet exceeds the minimum requirement, providing 6 square feet per worker (48 ÷ 8 = 6). While this would be acceptable and even beneficial, it's not the minimum required amount specified in the regulation, making it an incorrect answer for this specific question.
Option B: 32 square feet
32 square feet provides only 4 square feet per worker (32 ÷ 8 = 4), which is 1 square foot less than the required 5 square feet per person under Cal/OSHA Section 3395. This deficiency could compromise worker safety during heat exposure.
Memory Technique
Remember 'High Five for Shade' - Cal/OSHA requires 5 square feet of shade per worker for heat illness prevention. Just multiply workers by 5!
