Builder fined $180,000, Subby fined $180,000 and Supervisor fined $18,000 after a trainee was pinned by a elevated work platform causing his death. The killed worker was tightening bolts over the joints of the metal roof purlins. The task was carried out from the platform of the boom lift at a height of 7.7 meters above ground level. The killed worker was noticed not to be wearing a harness and had been warned earlier. Later on the day he was found pinned between the platform and purlins. He did not respond when the supervisor called out to him. As the supervisor tried to lower the boom, the worker tumbled to the ground.
