Enclosures are divided into the following main groups -
Group I
For use underground in mines i.e. for use in the presence of methane (fire damp);
Group II
For use above ground and subdivided according to their suitability for use in atmospheres containing specific gases
and vapours as shown in the following table.

and not more than 16% (v/v) of carbon monoxide, the
remainder being a mixture of paraffin hydrocarbons and
inert gas.
