Abstract: Employees #1 through #3 and a coworker were working on the #4 press. As they were observing the hydraulic fluid levels, a connection on the hydraulic system ruptured and oil mist sprayed onto a hot aluminum billet. The oil flashed, creating a fire cloud. The sprinkler system immediately extinguished the fire; however, Employees #1 and #2 sustained burns from the flash fire. Employee #3 injured his knee when he leaped over the conveyor to flee the fire cloud. All three were transported to the local hospital, where Employees #2 and #3 were treated and released. Employee #1 was admitted for treatment of second- and third-degree burns.
