GOVERNMENT factory inspectors today will check every work site using passenger hoists similar to the one which plunged 17 floors in Quarry Bay yesterday, killing 12 workers.
It is the biggest toll from an accident on a Hongkong construction site. The worst industrial disaster occurred in October 1986, when a fireball swept through a fur factory at Kwai Chung, after which 14 workers died of their burns.
Labour unionists inspecting the Java Road site yesterday called for licensing of hoist operators to prevent further tragedy.
Initial investigations by the Labour Department pointed to overloading as the cause of the accident at the new Towngas operations centre.
A sign had been attached to the lift after a breakdown yesterday limiting the load to 1,000 kilograms or eight occupants.
There are two freight elevators and only one passenger lift, utilising the system in which a cog, driven by an electric motor, engages a tooth rail, virtually climbing the building.
But yesterday, 14 men - including the operator - rode the passenger lift to the 20th floor, where two got off.
