Health risk management in the Tasmanian abalone diving industry.

Risk management is a systematic process applied to all aspects of diving operations. The process aims to reduce accidents and adverse outcomes to a minimum. Risk results from a combination of probability and consequence, and where this combination has major or extreme impact, the risk should not be tolerated. Over the four years 2001-2004, the incidence of decompression illness amongst abalone divers in Tasmania was 1.4 cases per 100 divers per year. Risk management in diving encompasses medical fitness, education and training, dive planning, equipment and maintenance, emergency procedures and equipment, and continual vigilance to remedy new risks as they are identified. There is still much to achieve in the Tasmanian abalone diving industry in all areas of risk management.
