Abstract: At approximately 3:30 p.m. on November 2, 2013, Employee #1, a fire fighter, who was also a Captain, with Los Angeles County Fire Department, Station 68, was fighting a structure fire. In order to extinguish this second story structural fire inside of a condominium unit, Employee #1 had dropped down in position from Captain to fire fighter. Employee #1 had donned all of his required Personal Protective Equipment (ppe) and was engaged in full fire suppression, using a 1.75 water line. Employee #1 was carrying a metal cutting tool in a pocket on his left forearm. The "knock down" event took approximately four minutes. During the overhaul event, which lasted approximately three minutes, Employee #1 felt burning on his arm. The tool in the pocket of his arm heated up, and as a result, Employee #1 sustained third degree burns to his forearms and knuckles. Employee #1's supervisor was outside of the building, and there were no direct witnesses to the incident. Employee #1 was hospitalized with burns on his arm and hand.
