This publication is intended to present general information regarding the characteristics and use of compressed air. To accomplish its purpose of supplying the answers to as broad a cross-section of inquiries as possible, it covers material of a general nature only. CGA has additional publications on compressed air, which can be found at www.cganet.com. In Canada, CSA Z180.1, Compressed Breathing Air and Systems and CSA Z7396.1, Medical Gas Pipeline Systems - Part 1: Pipelines for Medical Gases, Medical Vacuum, Medical Support Gases, and Anaesthetic Gas Scavenging Systems, should be consulted.
This publication provides information relative to the preparation, transportation, handling, storage, and use of compressed air. While it deals with compressed air used for human respiration, much of the information is equally applicable to compressed air for other purposes. It should be used in conjunction with CGA G-7.1, Commodity Specification for Air, which describes the specification requirements and lists the grades for air and prescribes methods of sampling and analysis.
