Four dead in British Columbia mine accident - CTV.ca
On Wednesday morning, an employee of mine-owner Teck Cominco Ltd. discovered the man floating in the well of the pumping station, which is above ground.
The employee phoned 911 and then tried to rescue the man, but the fumes overcame him, Ogilvie said.
Two B.C. Ambulance Service paramedics went to the call, but were themselves overcome by the fumes.
They were found by members of the Kimberley fire department that followed up on them.
