Abstract: Employees #1 through #6 were attempting to extinguish a fire in a one-story masonry structure and to rescue a restaurant patron. Employees #3 and #4 entered the building to rescue the customer. Employee #5 entered the approximately 42 ft by 30 ft structure with a hose line, followed by Employees #1 and #2. The fire became so intense that a flashover occurred and the fire fighters were trapped. Employees #2 through #4 managed to escape through a blown-out window. Employee #6 was injured while assisting Employee #3. Employee #1 was overcome with smoke and heat and never made it through the window. He was found dead approximately five minutes later. Employee #5 was overcome with smoke after he came out through the door and had started to assist Employee #6 at the window. Employees #2 through #4 were hospitalized.
