At approximately 8:00 p.m. on July 16, 1994, Employee #1, an operator in the alk y unit of an oil refinery, was between the acid regeneration system and the neut ralization system.

A line break at a T jus t past this control valve occurred while Employee #1 was trying to remove a bull plug from a 3/4 in. bleeder pipe.

Another bull plug was also on th e end of the bleeder. The P and IDs did not show this configuration for this ble eder. Employee #1 was exposed to acid-soluble oil or ASO, which contains 5 to 20 percent HF. He suffered chemical burns and was killed.
