In the United States, the OSHA standard 29 CFR 1910.119 Process Safety Management of Highly Hazardous Chemicals requires that a hazard analysis must be carried out for any process involving certain listed chemicals (see Appendix A of the standard) or involving more than 10,0001b (4535.9 kg) of flammable gas or liquid. Employers must involve employees in the hazard analysis, and it must be made available to employees and updated at least every 5 years. Employees and contractors must be trained in safe work practices associated with the identified process hazards. Eull details of these and other legal requirements as well as descriptions of the information that must be included in the analysis can be found in the standard. The most recent version of this standard and all other OSHA regulations are available at www.osha.gov. 

This appendix shows how the major elements of process safety management are reflected in API s RP 750, OSHA PSM Rule, and Environmental Protection Agency (EPA) regulations. The common points of each of the three documents are listed.

Process Safety Management (PSM) Standard (29 CFR 1910.119) PSM is for the prevention or minimization of the consequences of catastrophic releases of toxic, reactive, flammable, or explosive chemicals. This regulation applies to all processes that involve one or more of 137 listed chemicals (29 CFR 1910.119, Appendix A) above their threshold quantities or have 10,000 lbs. or more of a flammable liquid or gas, as defined by the U.S. OSHA HCS [29 CFR 1910.1200(c)], This includes n-hexane, hexane isomers, and all solvents listed in Table 14.10.3.

On July 17,1990, OSHA issued a proposed rule for the management of hazards associated with processes using highly hazardous chemicals. The agency finalized this rule, called the Process Safety Management Standard, on February 24, 1992. In an appendix to the proposed rule, OSHA discussed several methods of process hazard analysis. That discussion, which may be helpful for those doing job hazard analyses, follows ...

Like OSHA s Process Safety Management (PSM) Program, which is designed to protect workers from accidental releases of hazardous substances, the RMP rule addresses specific chemicals/materials (compounds) RMP addresses the accidental release of over 100 chemical substances that are listed in an appendix to the rule. The RMP chemicals listed include 77 acutely toxic chemical compounds, 63 flammable gases, and others. Threshold quantity levels range from 500 pounds to 20,000 pounds. EPA estimates that over 140,000 sources are covered by the rule. The universe includes chemical and most other manufacturers, certain wholesalers and retailers, drinking water systems, wastewater treatment works, ammonia refrigeration systems, chemical wholesalers and end users, utilities, propane retailers, and federal facilities.
