The high level ,of protection, required by ,protective clothing, (PPC) severely impedes ,heat, exchange by sweat evaporation. As a result work associated with wearing PPC, particularly in hot environments, implies considerable physiological strain and may render workers exhausted in a short time.
“Environmental risk factors for heat illness” means working conditions that create the possibility that heat illness could occur, including air temperature, relative humidity, radiant heat from the sun and other sources, conductive heat sources such as the ground, air movement, workload severity and duration, protective clothing and personal protective equipment worn by employees.
Based on the risk assessment, the selection of protective clothing with the appropriate level of protection for workplaces with heat and flames should be carried out. It is required to take measurements of intensity of hazardous and dangerous factors present in the work …
April 1 – Employers must ensure the outer layer of clothing worn by an employee is flame-resistant when estimated incident heat energy exceeds 2.0 cal/cm². April 1 – The employer must ensure employees with exposure to electric arc hazards wear protective clothing and other protective equipment with an arc rating greater than or equal to the estimated heat energy whenever it exceeds 2.0 cal/cm².

The heat from an arc flash can melt clothing from several feet away, especially if the clothing is made of a synthetic blend, raising the potential for health complications beyond the burn itself. Wearing thermally resistant arc flash protective clothing outlined under the requirements of NFPA 70E makes sense.
Abstract. There is little doubt that ,heat, stress affects many workers adversely and that ,protective clothing, generally adds to the burden. The ACGIH threshold limit value for ,heat, stress is the guiding document for evaluation of ,heat, stress in the United States.
