Davis Submerged Escape Apparatus
Davis Submerged Escape Apparatus (DSEA) is a type of underwater breathing apparatus that was designed for escape from sunken submarines. The apparatus was invented by Sir Robert H. Davis, head of Siebe Gorman, a British company that developed diving and submarine escape equipment.
History[edit | edit source]
The Davis Submerged Escape Apparatus was first introduced in 1927. It was adopted by the Royal Navy and was used extensively during the World War II period. The DSEA was the standard issue escape gear in British submarines from the 1930s until it was replaced by the Steinke hood in the 1960s.
Design and Function[edit | edit source]
The DSEA consists of a rebreather bag containing oxygen and a mouthpiece with a nose clip. The bag is filled with pure oxygen from a small cylinder. The user exhales into the bag, where the exhaled air is scrubbed of carbon dioxide by a chemical reaction and then re-inhaled. The apparatus is designed to be used at depths of up to 30 metres.
The DSEA is designed to be simple to use, even in the stressful and potentially disorienting situation of a submarine escape. The user simply has to put the mouthpiece in their mouth, clip their nose shut, and breathe normally. The apparatus provides a constant supply of oxygen, allowing the user to ascend to the surface at a controlled rate to avoid decompression sickness.
Legacy[edit | edit source]
The Davis Submerged Escape Apparatus played a significant role in the history of submarine escape technology. It was the first apparatus of its kind to be adopted by a major navy, and its design principles have influenced subsequent developments in the field. Today, the DSEA is remembered as a pioneering piece of equipment that contributed to the safety and survival of submarine crews.
