THUNDER BAY - A carbon monoxide detector at a Winnipeg Avenue home alerted residents to a potentially dangerous situation early Saturday morning.
Thunder Bay Fire Rescue crews responded to reports of a carbon monoxide alarm sounding at a home on the 100 block of Winnipeg Avenue at approximately 6 a.m. Saturday morning.
Arriving crews discovered a carbon monoxide level of 961 parts per million inside the home, as well as the presence of natural gas. A carbon monoxide level of just nine parts per million is considered acceptable for short-term exposure.
Those inside the home had already evacuated and Union Gas shut off the natural gas supply to the home.
A faulty water boiler was determined to be the cause of the leak. The home was cleared of carbon monoxide and natural gas.
The residents were checked for carbon monoxide exposure but no signs were found. There were no reports of injuries as a result of the leak.
Thunder Bay Fire Rescue is reminding all homeowners and business owners to ensure they have properly working carbon monoxide detectors and smoke alarms. As in this situation, the residents were alerted to a potentially lethal situation from an odorless toxic gas by a working carbon monoxide detector.
