Make the right call when carbon monoxide is detected

(NC)-Carbon monoxide (CO) is a tasteless, colourless and odourless poisonous gas often referred to as the "silent killer". It is produced when fuels such as natural gas, oil, wood, propane and kerosene do not get enough air to burn up completely. Damaged or blocked venting inside heating systems, as well as inadequate air flow can allow CO to build up inside the home.

The Heating, Refrigeration and Air Conditioning Contractors of Canada (HRAC) recommends that homeowners follow these measures if you have concerns about carbon monoxide:

• Proper maintenance of fuel-burning appliances, such as furnaces, and their venting systems is an absolute priority and should be your first call. Schedule an annual inspection with a qualified heating contractor at 1-877-411-HRAC (4722).

• If you are exhibiting symptoms of carbon monoxide poisoning, such as nausea, headache, burning eyes, confusion and drowsiness, leave the home and seek medical attention immediately. Call 911 or your local emergency service.

• If you have a carbon monoxide concern due to a specific condition but have no symptoms of poisoning, leave the home and call a qualified heating contractor at 1-877-411-HRAC (4722) to assess the situation.

• If you smell the odour of natural gas call your local natural gas utility.

Keep in mind, fumes from automobiles and gas-powered lawn mowers also contain carbon monoxide and can enter a home through walls or doorways if an engine is left running in an attached garage.

Quite often, homeowners instinctively call their local natural gas utility thinking that the utility also services and sells home heating and cooling systems. This is not the case. Only a qualified HVAC contractor can provide this service so keep these numbers on hand at all times. It could end up saving you valuable time.
