Report of a diver making a rapid ascent to the surface after his drysuit direct feed jammed open. Preliminary incident report only. No further details. B.
Following a charity swim of approximately half a mile the participants were posing for a group photo when two divers felt dizzy and nauseous. One of the divers then became unconscious. In both cases it was found that the cause of the problem was too tight a neck seal. Both divers recovered quickly once their neck seals had been removed. B.
During a holiday in the Red Sea a diver felt ill in the evenings after diving, with shaking and chest pains on breathing. He recalls noticing water spray in his mouth during dives but did not connect this with the problem until his return to the U.K. where he was diagnosed as having suffered Salt Water Aspiration Syndrome. His regulator, which was of the side mounted exhaust valve type, was only a few months old. B.
Whilst performing a navigation exercise at 10m, a novice diver sank to 20m because air was leaking from the dump valve of her stab jacket. The leak was sufficiently large that the direct feed was effectively useless. She was assisted to the surface by her buddy, using the emergency cylinder. The jacket was returned to the dealer who found a piece of the exhaust valve was missing. B.
A diver using a twin hose demand valve was practising mask and mouthpiece clearing. His demand valve freeflowed on removal as expected, but offered him no air on replacement in his mouth. He tried to clear it twice without effect and then made an assisted ascent to the surface using his buddy's octopus. B.
Whilst on a dive to 32m a diver's recently serviced demand valve failed. Neither the second stage or the octopus gave sufficient air and an assisted ascent was made to the surface with his buddy. B.
A trainee connected his drysuit direct feed hose to the high pressure port of a club DV by mistake. When he turned his air on the hose ruptured with a loud bang. There were no injuries or other damage. B.
During a dive to 30m in the Lake District a diver's DV began to freeflow. He was able to make a normal ascent, but had run out of air by the time he reached the surface. B.
During a dive in a freshwater lake a diver's demand valve began to freeflow at a depth of 50m. He ascended normally as far as 30m whereupon an assisted ascent was made to the surface due to his air supply having been exhausted. B.
A diver made a free ascent to the surface from a depth of about 7m when the mouthpiece from her regulator became detached from the second stage. Her buddy offered to share but she preferred to make a free ascent. Subsequent examination showed the demand valve mouthpiece was a push fit only and was not secure. B.
Report of an SMB becoming detached from its line due to a broken connection. The cover boat noticed the buoy was moving more quickly and shortly afterwards the divers surfaced without problem. Attempts to recall the divers were unsuccessful. B.
Whilst attempting to adjust her buoyancy a diver's ABLJ failed at depth. The ABLJ mouthpiece fell off causing the jacket to deflate. She gained buoyancy by releasing her weightbelt and ascended to the surface without further problems. B.
During ascent from a dive to 39m a diver's regulator failed and suddenly began to let in large amounts of water. He switched to his Air II and ascended normally. On inspection afterwards, it was found that the second stage cover was slightly unscrewed and that the diaphragm had distorted allowing water in. There appears to be a design weakness with this regulator. B.
During a fresh water dive to 24m a diver's second stage began to freeflow. He switched to his octopus and made a normal ascent to the surface with his buddy. No other problems were experienced but his cylinder was empty on arrival at the surface. B.
During a dive to 30m a diver's demand valve started to freeflow. He and his buddy made a normal ascent to the surface by which time his air supply was almost exhausted. On inspection, the valve was found to have a faulty first stage seat. B.
