Currently, when a new home is built it must have carbon monoxide alarms installed, and many municipalities (Orillia for one, as of April 2nd 2013), have passed bylaws so older homes must now be equipped with these crucial safety devices as well. The bylaw applies to all homes that use any flammable fuel like natural gas, propane, heating oil, kerosene, coal, gasoline, wood or charcoal (heat, appliances, fireplaces) or have an attached garage. Carbon Monoxide Alarm – Effective April 2 2013
Just like smoke alarms, carbon monoxide alarms should be within 16 feet of every sleeping area.
When assessing your existing alarms remember — just like your milk in the fridge – if it’s outdated, don’t count on it. Smoke alarms have a “replace by” date. It is usually 10 years (some just 5 years) after it is installed. Even if the test button still emits sound it only checks that the noise maker works, it does not guarantee the alarm can still detect smoke. CO alarms have a 5 or 7 year “replace by” date (depending on the manufacturer). Chemicals used to detect the carbon monoxide deteriorate with age and cannot be relied on past their stated lifespan.
