Types of Diving Helmets - Thursday, April 28, 2016

There's a lot of history to diving helmets and masks.

The Deane brothers, who also penned the first diving manual, invented the first diving helmet in the 1820s. With their partner, Augustus Siebe, they also created a helmet with a valve that could attach to a full length canvas suit.

Throughout the years, a variety of different helmets have been invented, many of which are still in use today.

The Standard Commercial Diving Helmet

The standard commercial diving helmet was first produced in the mid-19th century and is still in production today. The helmet is heavy, as it is expected to be used extensively, sometimes in tough environments. Many commercial diving helmets have a large window in the front and two smaller side windows. In addition, they typically contain a twelve bolt breast plate and are made with copper and brass.

The Lightweight Helmet

A lightweight helmet, also known as the Sponge Helmet, was developed for divers who spent many hours underwater to prevent fatigue, and is typically cheaper than a heavyweight helmet. There are many types of lightwater helmets that are popular today. Here are a couple of options that are commonly used for commercial diving projects:

The SuperLite Helmet (The Open Circuit Helmet)

The SuperLite Helmet, produced by Kirby Morgan, is a type of open circuit helmet, which means that airflow is controlled by the diver.

Free-flow Helmets

In free-flow helmets, air is not controlled by the diver, but instead flows continuously throughout the dive. These helmets are often used for shallow water diving and hazardous materials diving. Free-flow helmets typically have a very simple design concept.

Full Face Diving Masks

Often used by commercial diving companies (although not considered a heavyweight helmet) full face diving masks have all of the components of the typical modern diving mask, including protection for the entire head from the water, breathing gas, and a means to communicate with other divers and those at the surface. However, as an added benefit, the diver is protected should he or she fall unconscious for any reason while diving. While many masks include a mouthpiece that the diver has to hold between the teeth at all times, full face masks do not require performing this conscious action in order to continue to breathe.

Most full face masks have defogging systems so that the faceplate does not fog up when the diver descends. They should also include an emergency gas source, in case there is a problem with the primary supply. The full face mask should be fitted last, around the other diving materials.
