OSHA PSM Standard
Process Safety Management of Highly Hazardous Chemicals
The objective of 29 CFR 1910.119, the Process Safety
Management (PSM) Standard, is to prevent the release of highly
hazardous chemicals that could lead to a catastrophe in the workplace
or the surrounding community.
The PSM Standard applies to any process where highly
hazardous chemicals are used, stored, moved, handled, processed,
or manufactured. These chemicals include:
Designated toxic or reactive chemicals listed
by OSHA at or above their designated threshold quantity. Chemicals
such as chlorine, sulfur dioxide, ammonia, nitric acid, hydrochloric
acid, and hydrofluoric acid are included.
Flammable liquids or gases in quantities of
10,000 pounds or more in one location except for hydrocarbon
used as workplace fuels.
The PSM Standard requires employers to develop a
comprehensive program to identify and evaluate the potential hazards
associated with the use of these chemicals, and to identify and
implement measures for prevention of chemical releases that could
occur as a result of failure in process, procedure or equipment.
The PSM Standard is "performance based," and provides
guidelines on what must be done, but does not specify how it must
The PSM Standard consists of 14 elements that affected
facilities must address. The elements are integral to a complete
program and therefore exhibit some interdependency. They are:
The PSM Standard is the required prevention program
for the Environmental Protection Agency's "Risk Management
Program Rule" for Program 2 (modified) or Program 3 processes.
Although the primary focus of the PSM Standard is
to prevent or minimize the consequences of releases of toxic,
flammable, or explosive chemicals, the standard may exhibit other
benefits. Integrated into operating and production schemes, potential
benefits could include:
Written operating procedures to address productivity,
quality and other aspects in addition to the required safety
Formal maintenance programs, addressing perhaps
predictive as well as preventive maintenance.
Training programs addressing safety, productivity,
quality and other process consideration
