What are some ways to reduce the risk of heat stress?

• A. Drink fluids
• B. Install ventilation
• C. Monitor temperature and humidity
• D. All of the above

Answer: (D)

The safest and most effective way to reduce heat stress is to combine hydration, environmental controls, and monitoring. Drinking fluids keeps workers hydrated, supports the body's cooling system through sweat, and reduces the risk of dehydration that worsens heat illness. Installing ventilation lowers the surrounding heat load and improves air movement, helping sweat evaporate and the body to cool more efficiently. Monitoring temperature and humidity lets you spot when conditions become risky, so you can adjust work pace, schedule breaks, provide cooling or shade, and ensure fluids are available. Together, these approaches address hydration, airflow, and real-time conditions, giving the strongest protection against heat stress.
