In Ontario, over 65% of carbon monoxide deaths and injuries occur in homes. Most people have heard of carbon monoxide and know that it's dangerous. However, it's often a mystery of where it comes from, how it's produced and what precautions can be taken to ensure it doesn't endanger you or your family.
What is Carbon Monoxide? |
Carbon Monoxide (CO) is a colourless, odourless, tasteless and toxic gas and is often referred to as the "silent killer". Carbon monoxide poisoning is a leading cause of accidental poisoning deaths in North America. Exposure to CO can cause flu-like symptoms such as headaches, nausea, dizziness, burning eyes, confusion, drowsiness and even loss of consciousness, without the elevated temperature associated with the flu. In severe cases, CO poisoning can cause brain damage and death. The elderly, children and people with heart or respiratory conditions may be particularly sensitive to CO. |
How is CO produced? |
Carbon monoxide is commonly produced as a by-product of combustion when common fuel-burning appliances and equipment that use natural gas, oil, wood, propane and kerosene, don't get enough air to burn up completely. When this happens, carbon monoxide can build up, especially in a confined room or space. This can lead to toxic effects on humans and pets. |

Install Carbon Monoxide Alarms, it's the law! |
A properly installed and maintained CO alarm can alert you to when the poisonous gas is present. They usually have a life expectancy of approximately 5-7 years or as indicated by the manufactures requirements. If the alarm sounds, evacuate your home quickly. Call the fire department from outside and ask them to check your home for the presence of carbon monoxide. Single Family Dwellings

In rental properties the landlord is responsible for the installation and maintenance of CO alarms. The landlord is also responsible for providing the tenant with CO alarm maintenance instructions. Tenants are responsible for notifying the landlord as soon as they become aware that a CO alarm in their unit is disconnected, not operating, or its operation is impaired. Also, tenants shall not disable their CO alarms. In condominiums, the owner of the suite is responsible for the installation and maintenance of CO alarms in the suite. Often, there are agreements between the owner and the condominium corporation in which the corporation takes on this responsibility on behalf of the owner. In a situation where the condominium owner rents out the suite to a tenant, the owner takes on the role of the landlord and is responsible for the installation and maintenance of the CO alarms. |
