A full-face diving mask is a type of diving mask that seals the whole of the diver's face from the water and contains a mouthpiece, demand valve or constant flow gas supply that provides the diver with breathing gas.

The legal constraints commonly only allow the use of surface supplied diving equipment – scuba equipment is generally not permitted for hazmat diving. [3] One of the features common to hazmat diving equipment is breathing gas exhaust systems that minimise the risk of backflow of contamination through the exhaust valves into the helmet.
The usual meaning of diving helmet is a piece of diving equipment that encases the user's head and delivers breathing gas to the diver, but the term "diving helmet", or "cave diving helmet" may also refer to a safety helmet like a climbing helmet or caving helmet that covers the top and back of the head, but is not sealed. These may be worn ...
Diving safety is the aspect of underwater diving operations and activities concerned with the safety of the participants. The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team.
The scuba mask (half-mask) is equalised during descent by periodically exhaling through the nose. During ascent it will automatically equalise by leaking excess air round the edges. A helmet or full face mask will automatically equalise as any pressure differential will either vent through the exhaust valve or open the demand valve and release ...
