Compressed Gas Association

The Compressed Gas Association (CGA) is an American trade association for the industrial and medical gas supply industries.

The CGA publishes standards and practices that codify industry practices. In cases where government regulation is inspecific, CGA documents are considered authoritative. CGA falls into a group of trade associations whose publications are relied on by government. These groups include the National Fire Protection Association (NFPA) and ASTM International. For example, the state of Montana, the U.S. Army, and OSHA point to CGA documents for regulatory guidance. Provided by Wikipedia
