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. 517 $aThermal exposure sensor for fire fighters 606 $aFire fighters$xSafety measures 606 $aFire extinction 615 0$aFire fighters$xSafety measures. 615 0$aFire extinction. 700 $aDeshmukh$b Atul$01387634 701 $aBryner$b Nelson P$01387635 701 $aCasali$b John G$01387636 701 $aDeshmukh$b Atul$01387634 701 $aLancaster$b Jeff A$01387637 701 $aMcLane$b Roy A$01387638 712 02$aNational Institute of Standards and Technology (U.S.).$bEngineering Laboratory. 801 0$bNBS 801 1$bNBS 801 2$bGPO 801 2$bNBS 906 $aBOOK 912 $a9910711380003321 996 $aThermal exposure sensor for fire fighters$93437716 997 $aUNINA
