Investigation Summary
On March 15, 1973, working in an oil refining operation, Employees #1 through #4 were starting to bring a coker on line when a 2 in. diameter by 6 in. long pipe nipple, which is attached to the heater, developed a leak. The leak, which was approximately 2 1/2 in. long and 1 in. wide, allowed hot gas-oil to flow onto hot metal and the vapors to flow to the gas-fired heaters. A large fire with heavy smoke resulted and was put out in approximately 20 minutes. Employees #1 through #4 were hospitalized for smoke inhalation. A pressure gauge or the attached piping was the initial source of the fire.
