As global temperatures rise, outdoor workers are increasingly at risk of heat stress, a condition that can lead to heat stroke, heat exhaustion, heat cramps, or heat rashes. At T. Harris Environmental Management Inc., we understand the importance of protecting our employees from the dangers of heat stress. Here’s a comprehensive guide on recognizing, preventing, and managing heat stress in the workplace.
The Impact of Heat Stress
Heat stress can significantly affect both employees and employers. The risk of accidents increases by 7-15%, decreases productivity by 1-3% per every degree over 25°C, and raises costs from potential illness, injury, and high turnover rates due to heat-related illnesses1. Recognizing the symptoms and implementing preventive measures are crucial to ensuring a safe work environment.
Symptoms of Heat Stress
- Heat Exhaustion: Heavy sweating, weakness, dizziness, nausea, and headache.
- Heat Cramps: Painful muscle cramps, often in the abdomen, arms, or legs.
- Heat Stroke: High body temperature (above 104°F), confusion, loss of consciousness. This is a medical emergency and requires immediate attention.
Heat Stress Management Program
For Employers
- Implement a Heat Stress Management Program
- Measure workplace temperatures using Wet Bulb Globe Temperature (WBGT) or Heat Index (HI).
