What is Compressed Gas?
A compressed gas is any gas stored under pressure in a cylinder or container. Compressed gases include oxygen, nitrogen, hydrogen, acetylene, and carbon dioxide cylinders used in laboratories and industry. They require careful handling due to hazards of high pressure, potential toxicity or flammability, and the risk of cryogenic injury from liquefied gases.

Frequently Asked Questions
A compressed gas is any gas stored under pressure in a cylinder or container. Compressed gases include oxygen, nitrogen, hydrogen, acetylene, and carbon dioxide cylinders used in laboratories and industry. They require careful handling due to hazards of high pressure, potential toxicity or flammability, and the risk of cryogenic injury from liquefied gases.
Compressed gases are used as fuel (acetylene, propane), oxidisers (oxygen), inert atmospheres (N₂, Ar), refrigerants (CO₂, NH₃), analytical carrier gases (He, H₂ in GC), medical gases (O₂, N₂O), and industrial feedstocks (H₂, Cl₂, CO).
Compressed gas cylinders must be secured upright (chain/strap to wall) to prevent tipping and valve damage. Never store fuel gases with oxidising gases. Check for leaks using soapy water. Use regulators rated for the specific gas. Transport only with valve caps fitted.
The formula or notation for Compressed Gas is: PV = nRT
