Heat Is More Than Discomfort—It’s a Profit Killer

Protect Workers While Boosting Productivity This Summer

According to OSHA, heat stress sidelines thousands of U.S. workers every year—costing companies labor hours, medical expenses, and, in the worst cases, lives. Below is a quick guide to what heat does to the body, key national awareness dates, and how the Tennessee Chill Box® CB8000 closes the safety and productivity gap.


What Is the Heat-Stress Index?

The heat index blends air temperature and humidity into a single “feels-like” value. As it climbs, risk escalates fast:

Heat Index (°F) Effects on the Body Precautions
80 – 90 Mild fatigue Hydration & periodic shade
91 – 103 Heat cramps, exhaustion risk Frequent water breaks, shaded rest
104 – 124 Heat exhaustion likely; heat-stroke possible Cooling systems, lighter schedules
125 + Heat stroke highly likely Emergency cooling, consider work stoppage

June Heat Stress Awareness Month (all month) Prime time to audit PPE and cooling plans
