Carbon Monoxide Safety






Carbon monoxide (CO), often dubbed the “Silent Killer”, is an odourless, colourless gas that can be poisonous even in small amounts.

Symptoms of CO poisoning are similar to that of a flu, just without the fever. Exposure to CO can cause:

  • nausea
  • headache
  • burning eyes
  • confusion
  • drowsiness
  • loss of consciousness
  • even death.

Children, the elderly, pregnant women and pets can be especially vulnerable.

According to TSSA, more than 65 per cent of injuries and deaths related to carbon monoxide poisoning occur within the home. Ontario homes have, on average, four to six fuel-burning appliances that are potential sources of carbon monoxide. These include:

  • furnaces
  • water heaters
  • boilers
  • clothes dryers
  • fireplaces
  • stoves
  • barbecue
  • portable generators
  • space heaters.

Poor installation or maintenance of these appliances, the use of appliances not designed for indoor use, damaged or blocked venting, or inadequate airflow can cause dangerous levels of CO to build up inside your home, garage, cottage – virtually any enclosed space under certain conditions. The good news is that injuries and deaths from carbon monoxide poisoning can be averted with some simple precautionary measures.
