The Compressed Gas Association (CGA) is modernizing the CGA Handbook of Compressed Gases by making it a virtual tool. The gas monographs are now available in electronic format and can be accessed online.

The gas monographs provide information on the properties, uses, emergency response, safety and special handling considerations for 58 of the most common compressed gases. Each gas monograph opens with basic identifying information: chemical name of the gas, its chemical symbol, synonyms, American Chemical Society Chemical Abstracts Service registry number, U.S. Department of Transportation and Transport Canada proper shipping name, classification, labels, assigned UN number, and Globally Harmonized System of Classification and Labeling of Chemicals (GHS) classification.

The text of each monograph is divided into the following sections:

  • Identifying information
  • GHS classification
  • Physical constants
  • Vapor pressure curve (if applicable)
  • Description
  • Uses
  • Physiological effects
  • Materials of construction
  • Safe storage, handling and use
  • Emergency response/handling leaks and emergencies
  • Disposal
  • Containers
  • Cylinder valve outlet connections
  • Pressure relief devices
  • References

The monographs are arranged in alphabetical order for easy reference with the ability to search for a key word and mark a monograph as a “favorite."
