Definition & Explanation

A freight forwarder receiving pressurised gas cylinders, cryogenic liquid oxygen, or propane cartridges for loading is handling Class 2 dangerous goods – substances that are gaseous under standard conditions but transported in compressed, liquefied, or refrigerated form. The class breaks down into three divisions: flammable gases (2.1, e.g. propane, hydrogen), non-flammable and non-toxic gases (2.2, e.g. nitrogen, compressed air), and toxic gases (2.3, e.g. chlorine, ammonia). Pressure vessels must be tested and certified to applicable standards; cryogenic containers for liquefied gases additionally require thermal insulation. The designation 'Class II' is not current regulatory terminology – the authoritative label is 'Class 2' under ADR, the IMDG Code, and IATA-DGR.
