Investigation Summary
On March 25, 1989, Employee #1 was operating a vacuum truck that was emptying a 5,682-liter lube oil reservoir for the compressor on an alkalization unit. Due to a mechanical failure of the compressor, isobutane mixed with seal oil and approximately 1135 liters of contaminated oil was pumped into the lube oil reservoir. The flash point of the oil was lowered from 198 degrees to 23 degrees Celsius. Employee #1 had not grounded or bonded the truck to control static electricity, and the flammable vapors ignited. The resulting explosion killed Employee #1, and caused first-, second-, and third-degree burns over the face, head, hands, and arms of Employee #2. Employee #2 was hospitalized for his injuries.
