Abstract：Objective To evaluate the workers' performance in high temperature and airtight chambers by measuring environmental heat stress and personal physical and mental ability in order to provide guideline for intervention for health and performance.Methods Environmental heat stress was measured using portable Temp QUES 36 thermal environment monitor. Cardiac function index as the physical ability was measured according to the military standard "Measurement and evaluation of physical fitness for soldiers (JB 1337-92)". Cognitive ability was assessed by basic cognitive ability test (BCAT).Results According to the standard "Occupational exposure limits for hazardous agents in the workplace (GBZ2.2-2007)", there were two kinds of chambers, normal and high temperature by measurement of the environment hot stress. The Wet-bulb globe temperatures (WBGT) were 22.72±1.85℃ in the normal and 28.86±3.93℃ in the high chamber respectively. The cardiac function index and the basic cognitive ability score of workers were 6.58±1.80 and 62.14±10.19 in normal temperature chamber, 10.78±2.55 and 53.29± 14.28 in high temperature chamber, indicating the physical fitness in the medium level in the normal and the low level in the high chamber. The difference of the data between the normal and the high was significant(P<0.05). No apparent change of the basic cognitive ability score was detected in the same chamber before and after 20 days works.Conclusion There are significant negative effects on the personal performance in the high temperature and airtight environment, which may be the result of long exposure.
