Abstract: At approximately 11:25 a.m. on August 5, 1994, Employee #1, an aluminum smelting furnace operator for Timco Standard Tandem, loaded the #1 reverberatory furnace with a bale of scrap aluminum that was to be melted and recycled. He closed the heavy steel furnace door and was removing a length of steel wire that had been used to bind together the compressed aluminum scrap when an explosion occurred inside the furnace. The steel door blew open and struck Employee #1 in the head. He was killed. At the time of the accident, Employee #1 was using the prescribed personal protective equipment. There are no safety orders in T8CCR that address industrial aluminum smelting. The employer is being cited for a violation of T8CCR 3328(e) because the furnace door was not designed or secured to minimize hazards caused by the release of mechanical energy or by loosening (swinging out).
