Stuck Direct Feed - Over-inflated Drysuit

Incident Date


Incident Description

1979 Keld Head Kingsdale: Diver A wearing a new drysuit had reached the jump line which goes up into the airbell at 213m. Proceeding up the main line he decided to inflate his suit to compensate for a slight increase in depth. The direct feed button stuck open causing the suit to over-inflate so that the diver went up to the roof. The direct feed had then become free but when he tried to fin downwards all the air from the chest went unto his legs so that he was stuck against the roof upside down. Bt bending his legs he was able to resume an upright position and so could dump some air out of his suit.
