Diving helmet

From WikiMD's Wellnesspedia

Diving helmet is a rigid head enclosure with a breathing gas supply used in underwater diving. They are worn mainly by professional divers engaged in surface-supplied diving, though many models can be used with scuba equipment.

History[edit | edit source]

The history of the diving helmet dates back to the early 19th century, when inventors began to develop designs that would allow humans to breathe underwater. The first successful diving helmet was reportedly created by Augustus Siebe, a German-born British engineer, in 1837.

Design[edit | edit source]

The design of a diving helmet includes a rigid shell that covers the diver's head and a seal that prevents water from entering at the neck. The helmet is usually constructed from a durable material such as copper or brass, and is often coated with a layer of tin to resist corrosion.

The helmet is connected to a surface-supplied air pump, which provides a continuous flow of breathing gas. The gas is delivered to the diver through a hose, and excess gas is vented through an exhaust valve.

Use[edit | edit source]

Diving helmets are used in a variety of underwater work, including salvage operations, underwater construction, and marine archaeology. They are also used in commercial and naval diving.

Safety[edit | edit source]

Safety is a major concern in the use of diving helmets. Divers must be trained to use the equipment properly, and the equipment must be maintained in good condition to ensure its reliability. Risks associated with diving helmet use include oxygen toxicity, nitrogen narcosis, and decompression sickness.
