Abstract: On July 30, 1990, Employee #1 and coworkers turned on the gas to relight the pilots. On July 25, 1990, 460 gallons had been delivered and the gas had been turned off. A gas leak was reported to the gas company the same day, and on July 26, 1990, a serviceman had responded and reported that the 600 gallon system was out of gas. When the gas was relighted, smokehouses #1 and #2 were lighted without incident, but smokehouse #3 exploded. Employee #1 suffered second-degree burns on his arms and chest. The gas company returned on July 31, 1990, to pressure check the systems. The safety valve for pilot #3 was removed and a replacement was ordered. The employer had been under the impression that the gas leak had been repaired.
