Compressed Gas and Equipment
Hazards associated with compressed gases include oxygen displacement, fires, explosions, and toxic gas exposures, as well as the physical hazards associated with high pressure systems. Special storage, use, and handling precautions are necessary in order to control these hazards.
Compressed gas and equipment is addressed in specific standards for the general industry, shipyard employment, marine terminals, and the construction industry.
This section highlights OSHA standards, directives (instructions for compliance officers), and standard interpretations (official letters of interpretation of the standards) related to compressed gas and equipment.
Twenty-five states, Puerto Rico and the Virgin Islands have
State Plans and have adopted their own standards and enforcement
policies. For the most part, these States adopt standards that are
identical to Federal OSHA. However, some States have adopted different
standards applicable to this topic or may have different enforcement
