This requires a portable life support system connected to the chamber during transit. Types of hyperbaric evacuation units include: A self-propelled hyperbaric lifeboat (SPHL) is an enclosed, motorised, survival vessel fitted with a hyperbaric chamber to transport divers under pressure, with a life support system and a crew to operate it. The ...

Once free, the sea turtle turns and begins to swim away. But then, an incredible thing happens. As Sutton continues to capture the scene with his go-pro camera, the turtle circles back.
Before a dive the equipment must be thoroughly checked that it is suitable for the dive and in good working order, particularly those components which are part of the life-support system – the breathing apparatus, which includes: [2]: 171–2 Non-return valve test (safety critical). Main air supply. Bailout check. Comms check.

NOAA also publish a Diving Standards and Safety Manual (NDSSM), which describes the minimum safety standards for their diving operations. Several editions of the diving manual have been published, and several editors and authors have contributed over the years. The book is widely used as a reference work by professional and recreational divers.
The life support system of a surface saturation accommodation facility provides breathing gas and other services to support life for the personnel under pressure. It includes the following components: [12] Underwater habitats differ in that the ambient external pressure is the same as internal pressure, so some engineering problems are simplified.
The Diving Certification model originated at Scripps Institution of Oceanography (SIO) in 1952 after two divers died whilst using university-owned equipment. [3] The then President of the University of California, Robert Gordon Sproul, restricted diving to those who had been trained through the program at SIO and thus "certification" was born.
