Abstract: A refinery hydrofluoric acid pump repressured during motor replacement operations. Employee's confusion due to lack of lockout procedures and training resulted in the unbolting of a pressurized hydrofluoric acid pump that was supposed to be depressured. The pump containment failed, releasing several hundred pounds of hydrofluoric acid almost instantaneously onto the unprotected employees. Employees #1 and #2 were killed and Employees #3 through #7 were hospitalized.
