When we think of safety vests, we usually think of the bright neon colors and reflective stripes. The amount and quality of the striping is regulated by OSHA, in the USA. Here, at Zentek Clothing, we think of the health of the worker wearing the vest. In studying heat in the human body, you have to be amazed at how well designed we are. But if our normal body temperatures of 97.7 F to 99.5 F drop to 95 F, we have hypothermia. On the other side, if our core temperature rises, to100.9 F it is considered hyperthermia. 104 F + is a medical emergency. Long before this temperature the body heat regulating mechanisms, get overwhelmed and the body core raises dramatically. This can result in confusion , endangering the worker and those he/she is working with. Our body temperatures vary throughout the day, but only by 1 degree.
The Zentek vests, are equipped with a two layered, heat regulating process. In extreme heat , over 90-100 F the worker can add temperature set cold packs ( 58 F ), and remove them, when the heat emergency is over, then the vest temperature will return to its all season comfortable state.
