The territory's first study on manual work in restaurants found that 90 per cent of workers have at some time complained of injuries. The study, by the Polytechnic University, showed that half those questioned had suffered injured hands, a quarter had damaged fingers, and another nine per cent complained of aching backs. Some 40 per cent of injuries were cuts, and nearly a third were burns and scalds. Rehabilitation sciences assistant professor at the Polytechnic, Simon Yeung Sai-mo, said most kitchen workers lacked any concept of safety and 'almost seem to think that injuries are inevitable'. Most of the slashes, scalds and aches could be avoided, he said. A total of 110 kitchen workers from six restaurants were interviewed.
