Several things can go awry when you're exploring a dark cave underwater, such as equipment failure, losing your way, or trying to deal with close to zero visibility while making your way to the exit. In spite of being heavily reliant on their buoyancy compensators, many divers also misused them. You need cave training and cave equipment to cave dive. Do Not Sell/Share My Personal Information. The tragedy led Young to declare the caves too unsafe for future diving explorations, going so far as to tell Gauna they should be sealed for good. Factors cited as causes of fatigue include excessive drag due to over-weighting, drag due to over-inflation of the BCD, and long surface swims in adverse sea conditions, and it was not restricted to unfit divers. Evidence of panic is derived from behavioural reports from eyewitnesses. Disabling agents associated with asphyxia cases included: (62%) insufficient gas, triggered by entrapment, equipment problems, or high gas consumption due to heavy exercise in rough conditions. Mutual Fund and ETF data provided by Refinitiv Lipper.
