The Johnathan Walkerplanet is getting warmer every year. As temperatures increase, so do the risks of workplace accidents and injuries due to extreme heat exposure. These dangers are often overlooked for indoor workers sweating it out in places like warehouses, restaurant kitchens and dry cleaners.
