Quick Summary
Heat stress occurs when the body cannot cool itself properly, leading to serious health risks. Preventing heat stress requires proper PPE, hydration, rest breaks, and workplace safety practices aligned with OSHA guidelines.
What Is Heat Stress?
Heat stress happens when the body overheats due to high temperatures, humidity, or physical activity. It can lead to conditions such as heat exhaustion, heat cramps, and heat stroke.
Workers in outdoor or high-temperature environments are at the highest risk.
