HM Coastguard responded to 66 decompression illness and 32 rapid ascent incidents in 2010 according to the MCA’s newly published diving report. Medical emergencies accounted for 32 incidents. The total number of incidents has increased in the last two years, sadly, including 12 fatalities.
Buoyancy remains a problem with many incidents of divers losing control of buoyancy, whilst at depth, on ascent and on the surface. The deployment of delayed marker buoys at depth and loss of buoyancy control whilst wearing a dry suit were significant causes of loss of buoyancy control. The report advises that divers familiarise themselves with new or different gear before planning deep dives and that they always dive within their limits.
