Classification of Gases Oxidizers, Inert and Flammable gases

Compressed gases can be classified as

Oxidizers are not flammable by them self, but will contribute to combustion as an oxidant. Fat or oil is not acceptable in combination with oxidizers.

Some common oxidizers:

Inert gases do not take part in combustion processes and they do not react with other materials. An inert gas supplied to a room or limited space will reduce the amount of oxygen and limit a combustion process of a fire. Inert gases are used in extinguishing systems where it is important to avoid water damage - rooms with electronic devices etc.

Some inert gases:

Flammable gases together with air or oxygen in the right concentration burns or explodes if ignited.

If the mixture is to lean or to rich the mixture will not ignite.

Some flammable gases:
