Class 2: Gases

Classification of hazardous goods

Class 2.1 Flammable Gas

They are - 454 kg (1001 lb) of any material that are gaseous at 20 ° C (68 ° F) or less and 101.3 kPa (14.7 psi) of pressure (a material which has a boiling point of 20 ° C (68 ° F) or less in the 101.3 kPa (14.7 psi)), which is:

1. Fuel to 101.3 kPa (14.7 psi) when in a mixture of 13 percent or less of air or
2. Has a flammable range at 101.3 kPa (14.7 psi) with a view of at least 12 percent regardless of the lower limit.

Division 2.2 Non-flammable, Gas Non-poisonous

This division includes compressed gas, liquefied gas, pressurized cryogenic gas, compressed gas, asphyxiate gas and oxidizing gas. Non-flammable, non-poisonous compressed gas (Division 2.2) includes any material (or mixture) which:

1. Manifested in a package of absolute pressure 280 kPa (40.6 psia) or greater in 20 ° C (68 ° F), and
2. Does not apply to the definition of Division 2.1 or 2.3.

Division 2.3 Oxygen gas

This is a - an additional subclass of 2.2 and a non-flammable gases of Division for compressed oxygen in gas or liquid state. Oxygen is considered a non-flammable, because he does not burn. High concentrations of oxygen greatly increase the rate and intensity of combustion.

Gas Division 2.4 poison gas

Poisonous by inhalation, means a material which is a gas at 20 ° C or less and the pressure of 101.3 kPa (material that has a boiling point of 20 ° C or less in 101.3kPa (14.7 psi)), and which:

1. Known to be so poisonous for people in order to prevent danger of the disease during transport, or
2. In the absence of adequate data on human toxicity, is presumed to be toxic to people, because during laboratory testing in animals was found to contain LC50, but not more than 5000 ml/m3.
