Rahman said the task was carried out without a written work permit from the main contractor, according to findings from an initial investigation by the department of occupational safety and health (DOSH).

A work prohibition notice had since been issued to the contractor involved.

“We want a fair investigation for all parties. That is why we stopped the work first and issued a work prohibition notice to the contractor.

“An investigation needs to be carried out before we can determine the real cause,” Bernama quoted him as saying during a site inspection today.

Rahman said the public works department and DOSH are carrying out the investigation under Section 15(1) of the Occupational Safety and Health Act 1994.

He also said that two other similar temporary structures in the area had had work halted pending safety confirmation.

“I have instructed the public works department and DOSH to simultaneously look at all similar work structures. If it is true that it involved a skylift, we will look into that aspect. If not, we have to find the exact cause,” he said.

The collapse narrowly missed a woman whose car was crushed. She was rescued by the public before fire and rescue personnel arrived.

Malaysia Rail Link Sdn Bhd, the project owner, said it would provide immediate financial assistance to the affected vehicle owner, while investigations were ongoing and claims were being processed.
