Does OSHA have a standard that covers working in hot environments?

No. However, under the OSHA Act, employers have a duty to protect workers from recognized serious hazards in the workplace, including heat-related hazards. Warmer and more humid weather can increase the risk to workers both outdoors and in indoor workplaces with hot conditions. Ways to reduce heat exposure and the risk of heat-related illness include engineering controls (such as fans, air conditioning, and increased ventilation), and work practices such as work/rest cycles, drinking water often, and providing an opportunity for workers to build up a level of tolerance to working in the heat. Employees need to be trained in heat illness signs and prevention steps via toolbox talks or training.
