Safety Guidelines for Compressed Gases and Cryogenic Liquids

Safety Guidelines for Compressed Gases and Cryogenic Liquids 

The very properties that make compressed gases, liquefied compressed gases, and cryogenic liquids useful in almost every area of modern life can also make them dangerous when mishandled. Some of these gases are stored in containers at high pressure, others at very low cryogenic temperatures (e.g., temperatures below -130°F or —90°C). Some are flammable, some are inert (which can pose hazards of asphyxiation due to displacement of air), others are oxidizers, while still others are corrosive or toxic. 

This chapter describes in general some of the potential hazards associated with com-

There is a great deal of information available on the physical and chemical properties of compressed gases and cryogenic liquids and the precautions to follow for their safe storage, transport, handling, and use. Years of experience with these products have resulted in numerous safety regulations, standards, guidelines, product and equipment specifications, and recommended practices and procedures.
