SASKATOON --
Residents of an apartment building in the city's Greystone Heights neighbourhood were evacuated Thursday evening after an emergency room doctor's hunch led to the discovery of potentially lethal levels of carbon monoxide (CO).
Around 6 p.m., an emergency room physician reported the potential issue, asking for a check on the building located on Bateman Crescent after observing symptoms in a patient.
After firefighters arrived and took readings, high levels of CO were detected, especially in the building's boiler room.
"When you have a reading such as we had in this building when it's over 400 parts per million (in the boiler room), people can die within two to three hours of exposure," said Saskatoon Fire Department Chief Morgan Hackl during a virtual news conference Friday morning.
