API 751:1999

Outlines an 11-step procedure for managing the hazards found in refining process units. The OSHA regulation "Process Safety Management of Highly Hazardous Chemicals" (29CFR Part 1910.119) and the EPA's "Risk Management Program" (RMP) rule (40CFR Part 68) also have a significant impact on hazards management for facilities in the United States. Process hazards management has excellent application to hydrofluoric acid (HF) alkylation units. These units handle liquefied petroleum gas (LPG) and hydrofluoric acid (HF) which, if released in quantity, may cause significant fire and toxic hazards. Each operating HF alkylation unit should have a process hazards management plan. Process hazards management plans used for HF alkylation units must comply with federal, state, and local regulations.
