Which is a typical heat stress management practice during extended operations?

• A. Continuous work without breaks.
• B. Hydration, rest and rotation, and rehab cooling and medical assessment.
• C. High caffeine while ignoring cooling.
• D. No hydration during rehab.

Answer: (B)

Heat stress management during extended operations relies on hydration, rest and rotation, and rehab cooling with medical assessment. Hydration helps maintain fluid balance and supports sweating, which cools the body and prevents dehydration. Rest and rotation give workers time to cool down and recover cardiovascular strain by spreading workload across crews. Rehab cooling creates a controlled transition from hot zones to cooler environments, allowing PPE to be doffed safely and enabling ongoing medical monitoring to catch early signs of heat-related illness. Pushing to work continuously without breaks, relying on caffeine to counter fatigue, or skipping hydration during rehab all increase heat illness risk and reduce performance.
