Abstract

Human responses and safe work time limits for persons wearing the US Army's Self-Contained Toxic Environment Protective Outfit (STEPO) with personal CO2 scrubber, O2 supply, and upper body cooling system were determined from human tests and human simulation modeling. STEPO is the Army's highest-level protective system. A rational thermal physiological model was assembled to simulate the responses and extend the human test results to other conditions. Comparisons between human and simulated responses include core and skin temperature, heart rate, thermal sensation, and water loss. Safe work time limits were until core temperature and heart rate exceeded 38.3°C (101°F) and 150 bpm.
