Heat Stress, as defined in the program, is the net heat load to which a worker may be exposed from which contributions?

• A. The total heat energy produced by a workload
• B. The heat load from environmental factors alone
• C. The net heat load to which a worker may be exposed from combined contributions of metabolic heat, environmental factors, and clothing requirements
• D. The amount of heat energy stored in buildings

Answer: (C)

Heat stress is the net heat load a worker may experience from the combined contributions of metabolic heat, environmental factors, and clothing. This means everything the body has to deal with heat-wise—the heat generated by the workload (metabolic), the heat coming from the surroundings (temperature, humidity, radiant heat, air movement), and the added resistance to heat loss from clothing. Together, these sources determine how much heat the body must dissipate to keep safe core temperature. That’s why the option that includes all three contributions is the best fit. It isn’t just the heat from the job itself, nor environmental factors alone, nor heat stored in buildings.
