A foreman notices an employee showing signs of heat exhaustion at 2 PM when the temperature is 102°F. According to Cal/OSHA, what is the minimum rest period required in shade?
Correct Answer
D) 5 minutes every hour
Cal/OSHA Section 3395 requires a minimum 5-minute rest period in shade every hour when temperatures exceed 95°F, with additional breaks as needed.
Why This Is the Correct Answer
Cal/OSHA Section 3395 (Heat Illness Prevention) requires a minimum 5-minute rest period in the shade for every hour of work when temperatures exceed 95°F. This is the baseline minimum; additional rest may be provided as needed based on conditions.
Why the Other Options Are Wrong
Option A: 10 minutes every 2 hours
10 minutes every 2 hours is less frequent than required. At 102°F — well above the 95°F threshold — the regulation mandates a rest opportunity every hour, not every two hours.
Option B: Employee must be sent home immediately
Sending the employee home immediately is not the regulatory minimum requirement specified by Section 3395 for rest periods. While the employee showing signs of heat exhaustion may require additional first aid response, the question asks about the minimum shade rest requirement under the regulation.
Option C: 15 minutes every hour
15 minutes every hour exceeds the minimum required by the regulation. While more rest is always encouraged in extreme heat, the legal minimum specified in Section 3395 is 5 minutes per hour.
Memory Technique
Remember '5-at-95': when temperature hits 95°F, workers get 5 minutes of shade every hour. The number 5 appears twice — 95°F and 5 minutes — making it easy to pair.
