Smoke Detectors Approved-type properly installed and maintained smoke detectors are critical life saving devices. While a smoke detector won't prevent or extinguish a fire, it can save one's life. Smoke detectors are designed to warn of fire danger in time to allow for escape or call for help. The ear-piercing alarm of the smoke detector may provide you and your family with the precious extra minutes that you need to escape, especially at night (when most fires occur).
When installing smoke detectors, the fire chief advises you to take the following steps:
Install at least one smoke detector in the hall leading to the bedrooms
Consider installing additional smoke detectors, especially if your home has more than one level
Make sure smoke detectors are of a type approved by Underwriters' Laboratories of Canada or other recognized testing laboratory
If your detectors are battery operated, check the batteries often to make sure the units are operational.
