Process Safety Management

Unexpected releases of toxic, reactive, or flammable liquids and es in processes involving highly hazardous s have been reported for many years. Incidents continue to occur in various industries that use highly hazardous s which may be toxic, reactive, flammable, or explosive, or may exhibit a combination of these properties. Regardless of the industry that uses these highly hazardous s, there is a potential for an accidental release any time they are not properly controlled. This, in turn, creates the possibility of disaster. Recent major disasters include the 1984 Bhopal, India, incident resulting in more than 2,000 deaths; the October 1989 Phillips Petroleum Company, Pasadena, TX, incident resulting in 23 deaths and 132 injuries; the July 1990 BASF, Cincinnati, OH, incident resulting in 2 deaths, and the May 1991 IMC, Sterlington, LA, incident resulting in 8 deaths and 128 injuries. Although these major disasters involving highly hazardous s drew national attention to the potential for major catastrophes, the public record is replete with information concerning many other less notable releases of highly hazardous s. Hazardous releases continue to pose a significant threat to employees and provide impetus, internationally and nationally, for authorities to develop or consider developing legislation and regulations to eliminate or minimize the potential for such events. This booklet, OSHA 3123, Process Safety Management, summarizes the OSHA final process safety management (PSM) standard. Employers and employees may prefer to read this booklet and a companion one entitled, “Process Safety Management - Guidelines for Compliance” (OSHA 3133), before studying the rule itself. The standard mainly applies to manufacturing industries—particularly, those pertaining to s, transportation equipment, and fabricated metal products. Other affected sectors include natural liquids; farm product warehousing; electric, , and sanitary services; and wholesale trade. It also applies to pyrotechnics and explosives manufacturers covered under other OSHA rules and has special provisions for contractors working in covered facilities.
