No injured cavers recorded.
While on a trip to dive the first and second sumps, a crew was in the first sump when a faulty buoyancy compensator (BC) inflated, forcing a diver to the roof of the passage. Debris had lodged in the mechanism. Almost simultaneously one of his regulators began to free-flow (uncontrolled release of air). While getting the regulator under control, the mouthpiece slipped out of his mouth and replacement was difficult with the BC pushing into his face.
A diver encountered equipment failure with a buoyancy compensator and regulator while diving in Tyson Spring Cave.
