Singapore, Dec 17 (PTI) The death of an Indian worker at a construction site in Singapore last year has been ruled a misadventure, according to a media report.
Muthaiyan Velmurugan, 28, was working at a construction site in Jalan Tan Tock Seng on November 4 last year when he was hit by falling material after a tower crane failed.
There is no basis to suspect foul play, said State Coroner Kamala Ponnampalam in her findings dated December 15, The Straits Times reported on Thursday.
Velmurugan was struck by a falling hook block from a tower crane after its horizontal beam, called a jib, buckled while lifting scaffolding material.
He was later pronounced dead by paramedics at the accident scene.
Another worker was injured by the chain slings of the crane and subsequently taken to the hospital.
The State Coroner said in her findings that the worksite accident was caused primarily by the entanglement of the right erection rope with the frame of the crane.
Erection ropes are used to hold and balance the jib in position for it to be installed and secured onto the head of the crane frame.
But they play no further role in the function and operation of the crane after the crane's luffing system -- which is used to raise or lower the jib -- has been installed, according to Ministry of Manpower reports cited by the state coroner.
Coroner Ponnampalam said the entanglement caused the rope to support the weight of the jib and the load which the crane was carrying. The rope eventually broke, with the jib jerking downwards in free fall.
The hook block and load also fell towards the ground, hitting Velmurugan and his colleague who were working in the vicinity.
The state coroner said the crane was not overloaded at the time of the accident.
She also noted that the MOM had identified several learning points and prevention opportunities arising from the incident, including recommending that the erection ropes be removed or disconnected and stowed away on the crane after the jib installation, if possible.
Ponnampalam said the ministry had checked with industry stakeholders and was not able to find any reports of a similar incident of tower crane failure involving erection ropes across the world.
'It would appear that this was the first such incident and the entanglement of the erection ropes was an unexpected and unanticipated behaviour,' she said. PTI GS SCY SCY
