Abstract
High temperatures encountered by mine rescue teams during emergency situations may cause severe physiological strain, hindering the men from carrying out rescue and recovery missions. A prototype ice- cooling garment (icg) was developed by the Bureau of Mines to alleviate physiological strain due to heat stress. The effectiveness of the garment was tested with acclimatized and unacclimatized subjects at a typical work rate (1,200 btu/hr) expected during rescue operations and at various hot environments (97 deg to 113 deg f dry bulb and 80 deg to 89 deg f wet bulb). During exposures with the ice-cooling garment, the subjects were able to maintain a safe deep body temperature of 100.4 Deg f or below. Without the garment, the deep body temperature rose beyond values of 100.4 Deg f, a condition considered unsafe for continuous work in hot conditions. Both heart rate and skin temperature values were lower while wearing the icg. Subjective observation also indicated a marked benefit by wearing the icg.
