Abstract This article summarizes research projects aimed at defining safe work limits for firefighters wearing protective clothing and working in warm environments. It examines strategies for reducing the thermal burden and extending operational effectiveness. Subjects wore their protective ensemble and carried their self-contained breathing apparatus and performed very light, light, moderate or heavy work at 25░C, 30░C and 35░C. Predicted continuous work times were then generated using a heat strain model that established limits for increases in body temperature to 38.0░C, 38.5░C and 39.0░C. The study revealed that replacing the duty uniform pants with shorts reduced the thermal strain for activities that lasted longer than 60 min. Adequate fluid replacement and forearm and hand immersion, increased exposure time (and work productivity) by 100%.
