How Diving Helmets are made?

Diving helmets are worn mainly by professional divers engaged in surface supplied diving, though many models can be adapted for use with scuba equipment.

The helmet seals the whole of the diver’s head from the water, allows the diver to see clearly underwater, provides the diver with breathing gas, protects the diver’s head when doing heavy or dangerous work, and usually provides voice communications with the surface (and possibly other divers). If a helmeted diver becomes unconscious but is still breathing, the helmet will remain in place and continue to deliver breathing gas until the diver can be rescued. In contrast, the scuba regulator typically used by recreational divers must be held in the mouth, otherwise it can fall out of an unconscious diver’s mouth and result in drowning (this does not apply to a full face mask which also continues to serve air if the diver is unconscious).
