SINGAPORE: A contractor tasked with carrying out tank cleaning operations at a PUB site was charged on Thursday (Jul 16) over alleged workplace safety lapses after two workers died in 2024.
The contractor, Stargroup, had been engaged by the national water agency for what was described as "routine" tank cleaning operations at Choa Chu Kang Waterworks.
On May 23, 2024, four workers from Stargroup and its subcontractor were cleaning a water treatment process tank.
Three of them later collapsed after entering an enclosed passage beneath the tank to close hand valves that had been opened earlier to drain water from the tank, the Ministry of Manpower (MOM) said in a press release on Thursday.
