Compressed Gas Association Standards

Compressed Gas Association Standards FAQ

What are hazards associated with compressed gases?

Hazards associated with compressed gases include oxygen displacement, fires, explosions, and toxic gas exposures, as well as the physical hazards associated with high pressure systems. Special storage, use, and handling precautions are necessary in order to control these hazards.

What is the standard pressure for gas?

The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atm pressure. This is the freezing point of pure water at sea level atmospheric pressure. At STP, one mole of gas occupies 22.4 L of volume (molar volume).

What is an example of compressed gas?

Common liquefied gasses include ammonia, chloride, propane and nitrous oxide. Non-liquefied gasses are also known as compressed, pressurized or permanent gasses. Oxygen, nitrogen, helium and argon are all examples of non-liquefied gasses. Acetylene is the only common dissolved gas and is very unstable chemically.

What are compressed gases?

Compressed gasses are gasses that are stored under pressure in cylinders. The three major types of compressed gasses are liquefied gasses, non-liquefied gasses and dissolved gasses. The pressure of the gas in a cylinder is usually recorded as pounds per square inch gauge (psig) or kilopascals.
