A lift worker died after falling down a shaft between a side wall and a lift in Quarry Bay yesterday. The 50-year-old man was making a routine inspection of the lift in Ling Pak Mansion at Parkvale in Greig Road at about 10.30am when he fell. The man was working on top of the lift, which was halted between the first and second floors, while another man was inside. Police say it appeared that he lost his balance when the lift suddenly moved. Firemen and a medical team, including a doctor, were called in, and rescuers took more than an hour to free him. The man suffered head injuries and lost consciousness as he was being taken from the shaft. He was declared dead at Pamela Youde Nethersole Eastern Hospital less than two hours later. Im Kit-hung, vice-chairman of the Hong Kong General Union of Lift and Escalator Employees, said such accidents were rare. 'In every inspection, there should be two lift technicians who work closely together to ensure safety,' he said. 'And there are buttons on the top of any lift that give a worker full control over the movement of the lift.' However, Im said it was hard to know what inspection work the technicians were carrying out, and workers might allow a lift to move intentionally. 'It is not necessary for a lift to be stopped all the time during an inspection. For some checking, workers have to move the lift up and down,' he said. The Labour Department and the Electrical and Mechanical Services Department are investigating the cause of the accident. The latter department requires contractors to ensure workers have relevant qualification and training. It will soon introduce a registration system requiring the 5,000 lift and escalator workers in the city to undergo retraining every five years.
