Abstract: On January 13, 2009, Employee #1, of Diamond Insulation, was cold and had gone into the mechanical room to get warm. Employee #2, a sheetrock taper, was in the mechanical room too. Employee #1 backed up near a "pot" style heater. He was walking away from the heater when he noticed the left side of his pants on fire. Employee #1 attempted to pat the back of his pants but he stated he could not control the flame. He then dropped on the ground and attempted to extinguish the flames. Employee #2 and another coworker noticed that Employee #1 pants were engulfed in flames and went to a nearby reverse flow backflow which had a hose attached for potable water use. Employee #2 and the other coworker held Employee #1 down and extinguished the flames with the water hose. Employee #1 was hospitalized for treatment of the burns he sustained from the fire. .
