The audiences for this guideline are the practitioner at a hot work site who is responsible for the heat management program, as well as the individual who is working in the heat. Environmental heat is a commonly occurring working environment; it is found at outdoor worksites, at indoor worksites with natural ventilation, at heat producing operations, and even in air-conditioned work areas where mechanical failure occurs in the cooling system or where the total heat load exceeds the capability of the cooling system. This guideline includes information on the way the human body stores heat, on potential illnesses from overexposure, methods for measuring and estimating the various components of heat exposure, limiting values of thermal exposure and work times in the heat, how these limits are affected by levels of acclimatization and clothing, and means of controlling heat exposure and heat stress. |
