Flame traps allowing passage of gas but not of flame or explosion wave
Definition statement
This subclass/group covers:
Devices which stop the expansion of pressure waves or fires by their constructional features, e.g. by cooling down the passing gas, thus suffocating the flame.

Special rules of classification within this group
Since most devices for collecting fire hoses do this by ensuring that the fire hose is empty (thus dry), devices for collecting hoses are in A62C 33/02.

Special rules of classification within this group
If devices use certain methods which are represented by a subgroup in A62B 99/00, they will be classified in the respective device group and in the respective method group. For example, devices to inert luggage compartments of airplanes will be classified in A62C 3/08 and A62C 99/0018.
