Sub Class 2.2 Non-Flammable, Non-Toxic Gases
With the risk of explosion (scattering, dispersion, etc.), not directly, but in a connected way, this class includes pressurized gases, liquefied gases, pressurized cryogenic gases, compressed gases in a solution, and oxidizing gases. Flammable and non-toxic gases are gases not included in 2.1 and 2.3 classes with a pressure content of 280 kPa (40.6 psia) at 20 ° C (68 ° F). They do not contain a high risk of explosion.
