See the full class list

A flammable gas (Division 2.1) is any material which is a gas at 20°C (68°F) or less and 101.3 kPa (14.7 psia) of pressure that is ignitable at 13 percent or less by volume with air, or has a flammable range with air of at least 12 percent regardless of the lower limit.

Division 2.2 — Non-Flammable, Non-Poisonous Gas

See the full class list

A non-flammable, nonpoisonous compressed gas (Division 2.2) exerts a gauge pressure of 200 kPa (29.0 psig) or greater at 20°C (68°F), is a liquefied gas or a cryogenic liquid, and does not meet the definition of Division 2.1 or 2.3.
