Diving-related deaths in Hong Kong waters, 2006-2009.

Diving is a popular recreational activity in Hong Kong, and there is an associated incidence of mortality. This individual case review of reported diving-related deaths occurring in Hong Kong waters between 2006-2009 inclusive, was conducted as part of the ongoing DAN Asia-Pacific dive fatality reporting project. The eight reported deaths involved one snorkeler and seven scuba divers. Six of the victims were male and two were female. The disabling injury in at least one death, possibly two, appeared to have been cardiac-related; two involved trauma from impact with boats; and asphyxia was believed to be the disabling injury in four or five fatalities. Two of the deaths occurred during open-water diver training and one during advanced diver training. Inexperience, pre-existing medical conditions, poor supervision, solo diving and poor sea conditions were key factors in these deaths. It is hoped that this review provides a suitable model for others to emulate in reporting dive fatalities.
