Carbon monoxide is known as the “silent” killer. The poisonous gas cannot be seen, smelled, or tasted, making it difficult to detect. It’s produced by fossil fuels such as wood, propane, natural gas, and heating oil during combustion.
“Fossil fuel appliances that are not functioning properly can quickly build up dangerous and even deadly toxic levels of carbon monoxide,” said Fire Prevention Officer Kevin McKelvey of the Gravenhurst Fire Department. “Being aware of the symptoms can also potentially lead to a successful outcome of someone affected by the abundance of carbon monoxide leaking into the home,” he added. Flu-like symptoms such as headaches, nausea, dizziness, and drowsiness are often experienced as the effects of carbon monoxide poisoning take over the body. Anyone who suspects they have symptoms of carbon monoxide poisoning should immediately go outside and call 9-1-1.
An annual inspection of your fuel-fired appliances by a competent, qualified technician can potentially save you and your family. “Early detection and repairs to a faulty piece of equipment can most definitely save lives,” says McKelvey, while also emphasizing the need to have working carbon monoxide alarms.
Even though carbon monoxide alarms have been required in Ontario homes and residential buildings since 2001, approximately 60% of Canadians do not have working carbon monoxide alarms in their homes. Each year, over 50 people die from carbon monoxide poisoning in Canada while many others are left severely affected by CO poisoning.
Carbon monoxide alarms should be located adjacent to sleeping areas and at least 15 inches from fuel-fired appliances. These alarms should be tested once a month to ensure the audible device is working. As dust often migrates to ceilings and walls, be sure to vacuum them once a month as well. If the alarm is 7-10 years old, it should be replaced.
Here are some potential dangers that the Canadian Gas Association recommends you watch out for:
Yellow Flames: Check the flame on all natural gas appliances regularly (it should be blue – a yellow burner flame can be a sign of carbon monoxide).
Furnaces: Remember to check and replace your furnace filter at least every three months. To be sure that your furnace exhaust system is working properly, it should also be inspected routinely by a licensed professional.
Blocked Vents or Chimneys: A blocked or restricted vent/chimney will reduce flue performance, increasing the chances of CO or other fumes spilling into the home. Be sure to clean your vents/chimneys regularly.
Car Exhaust: Despite having properly maintained exhaust systems, it is still possible that CO could get into your vehicle. Also, if you are idling in cold weather with poor ventilation the heating system can draw CO into the vehicle.
