Heat Stress Prevention: Elevate Worker Safety with Tennessee Chill Box

Why Heat Stress is a Workplace Emergency

As temperatures rise, heat-related illnesses become a silent but deadly threat to workers in high-heat environments. Whether in construction, manufacturing, industrial maintenance, or fire safety, prolonged exposure to extreme heat can cause heat exhaustion, heat stroke, and severe dehydration—putting lives at risk and reducing productivity.

According to the Occupational Safety and Health Administration (OSHA), heat stress impacts thousands of workers annually, leading to lost labor hours, costly medical incidents, and even fatalities.

How Heat Affects the Body

The heat stress index measures how temperature and humidity affect the human body. Here’s what happens as heat levels rise:

Heat Index (°F)	Effects on the Body	Precautions
80 – 90	Fatigue, mild discomfort	Hydration and rest breaks
91 – 103	Heat cramps, exhaustion risk	Frequent water intake, shaded areas
104 – 124	Heat exhaustion likely, heat stroke possible	Cooling systems, adjusted work schedules
125+	Heat stroke highly likely	Emergency cooling measures, work stoppage

When a worker is exerting energy in extreme heat, the body reacts by redirecting blood flow to the skin, increasing sweating, and accelerating heart rate. But as temperatures climb past safe thresholds, dehydration, dizziness, confusion, and muscle cramps set in—leading to heat-related injuries, fatigue, and lost productivity.

Heat Safety Month & Why Prevention Matters

May 30th is National Heat Awareness Day and makes a good segue for June’s Heat Stress Awareness Month, a crucial time to educate teams on preventative measures for extreme heat exposure. Investing in cooling solutions isn't just about comfort, it’s about worker safety, operational efficiency, and business success.

One of the best heat stress prevention tools is the OSHA-NIOSH Heat Safety App, which provides real-time heat index updates and actionable safety recommendations.
