Concerns have been raised over safety procedures inside WestConnex motorway tunnels after more than 300 workers were told to leave sections of the project.
A broken water pipe and power generator issue prompted a mass evacuation of workers from both ends of the tunnels at Haberfield and Homebush on Thursday morning, the Electrical Trade Union says.
The incident came after more than 200 workers downed tools on Tuesday when raw sewage overflowed from a portable toilet into the tunnel.
“Following both incidents, workers have reported concerns to the union about problems with the evacuation procedures, along with a lack of effective communication from management, which they fear could have deadly consequences if the evacuation was for a life-threatening emergency,” ETU secretary Justin Page said in a statement on Thursday.
“One incident might be bad luck, but when each day seems to bring another serious issue, it raises valid questions about how the NSW government is managing this project.”
WestConnex denied there was an evacuation of the tunnels.
“Following a power outage in a section of the New M4 Tunnels this morning some workers were redeployed to other areas of the tunnel, and some were sent home,” a statement to AAP said.
“There was no evacuation. Work is expected to recommence on the affected section of the project tonight.
“Safety of our workforce is always our first priority.”
Roads and Maritime Services said the number one priority during the WestConnex construction was the health and safety of workers.
