A police internal risk analysis shows high-speed boat chases by marine officers are the most dangerous type of police work.
By evaluating the likelihood of injuries and their probable severity, the analysis also identified motorcycle patrols, responding to 999 calls and patrols in rural areas as more risky than other tasks.
One of the worst injuries suffered by police last year was sustained by Constable Chu Chun-kwok, who almost lost his life when he was stabbed in the neck during a routine stop-and-search in Cheung Sha Wan in July.
But police figures show the majority of injuries sustained by officers are relatively minor. The police categorise injuries that require less than three days of sick leave as level one, and they make up about 80 per cent of cases.
Another 19 per cent are level two, which need more than three days' rest. The other 1 per cent are the most serious at level three.
Police investigate each level two and three accident, identifying its cause and look for preventive measures, said Superintendent Rod Mason, responsible for the force's occupational safety.
