Current turnout gear insulates the fire fighter to such an extent, encapsulating his/her entire body, that it is difficult for each individual fire fighter to understand how hazardous or hot the thermal environment is. Therefore, the natural heat-sensing mechanism of the body is incapable of sensing the ambient temperature, possibly putting firefighters at risk. A thermal sensing device that attaches to the visor of the head gear is designed to restore situational awareness of the firefighter by showing varying heat intensity through different colored warning indicators in the firefighter s line of sight. Human factors evaluation of the performance of the warnings in the thermal sensing device was conducted in laboratory-scale (i.e., climatic chamber experiments) and in full-scale (i.e. fire experiments in ISO room) environments. This report describes the laboratory-scale experiments and a second report describes the fullscale fire experiments. A static oven, representing the conductive type of heat; a fire equipment evaluator, with high speed convective flow loop, and a radiant panel, with intense heat flux were used to conduct laboratory-scale experiments.Thermal exposure sensor for fire fighters Fire fightersSafety measuresFire extinctionFire fightersSafety measures.Fire extinction.Deshmukh Atul1387634Bryner Nelson P1387635Casali John G1387636Deshmukh Atul1387634Lancaster Jeff A1387637McLane Roy A1387638National Institute of Standards and Technology (U.S.).Engineering Laboratory.NBSNBSGPONBSBOOK9910711380003321Thermal exposure sensor for fire fighters3437716UNINA
