What is a compressed gas?
In the United States, thousands of products are used, handled, and transported every day containing gases and mixtures of gases stored under pressure in cylinders. Most of these gases are classified as compressed gases.
OSHA defines a compressed gas as a gas or mixture of gases having, in a container, an absolute pressure exceeding 40 psi at 70° F (21.1° C). Also, a gas or mixture of gases having, in a container, an absolute pressure exceeding 104 psi at 130° F (54.4° C) regardless of the pressure at 70° F (21.1° C); or a liquid having a vapor pressure exceeding 40 psi at 100° F (37.8° C) as determined by ASTM D-323-72.
All compressed gases present physical hazards due to their high pressure. Compressed gases stored in cylinders can be classified as toxic, flammable, oxidizing, corrosive, inert, or non-flammable. Inert gases can displace air, causing an oxygen-deficient atmosphere. Corrosive, reactive, and toxic gases pose chemical hazards, while flammable or reactive gases can result in fire and exploding cylinders. A gas cylinder may have multiple hazards and represent a danger to employees. It is important to identify the potential hazards and communicate the means to avoid injuries and even death.OSHA 29 CFR 1910.101 - Compressed gases (general requirements)
