Summer is officially here, which means that it’s a good time to talk about the importance of heat stress prevention. Overheating is a dangerous possibility for outdoor workers, but the good news is that heat stress is preventable.
Understanding how heat affects the human body is a big first step to heat stress prevention. Learn more at our Heat Stress FAQs page on eSafetyStore. Plenty of rest, hydration and cooling apparel are all part of the solution.
The Cooling Vest is help prevent workers from overheating. The most frequently used Cooling Vests work either through evaporative cooling or phase change.
Phase Change Cooling Vests. The phase change vest uses chilled phase change inserts to maintain a comfortable cooling temperature (around 58 degrees F) for up to four hours. These inserts absorb body heat, which keeps the wearer cool.
Evaporative Cooling Vests. The evaporative cooling vest works the same way that sweat does, without the smelly side effects. Evaporative cooling vests are extremely absorbent. Just soak in cold water, and in a couple of minutes cooling polymers or cooling crystals in the vest absorb water and are able to hold it for hours. As the water evaporates it takes heat with it, keeping the wearer cool.
Cooling Vests aren’t just for keeping wearers from overheating either. Ergodyne is just one of many manufacturers that produces hi vis safety vests with cooling properties. These are perfect for road workers and others who need to stay cool and be seen.
