This booklet 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 chemicals, transportation equipment,
and fabricated metal products. Other affected sectors include natural
gas liquids; farm product warehousing; electric, gas, 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.
In each industry, PSM applies to those companies that deal with
any of more than 130 specific toxic and reactive chemicals in listed
quantities; it also includes flammable liquids and gases in quantities
of 10,000 pounds (4,535.9 Kg) or more.
