Make sure detectors are placed either on the ceiling or 15 to 30 cm below the ceiling on the wall. Locate smoke detectors away from air vents or registers; high airflow or “dead” spots should be avoided.

Smoke alarms are not suggested for kitchens, bathrooms or garages where there are fumes, steam or exhaust that could set them off unnecessarily.

Make sure the detectors in your place are in good operating condition. Test them once a month by pushing the test button.

Once a year, hold a lit cigarette, incense or a candle that you’ve just blown out, near the detector until the alarm sounds. If the alarm is battery-powered and doesn't sound, replace the battery and try again. If it's electrically connected to household circuits and doesn't sound, check the fuse and try again. It should sound within 20 seconds.

If your battery-powered detector begins to emit its low-power warning, such as a chirping sound, replace the battery immediately with a fresh one. Make the replacement of batteries a seasonal task; change the battery, for instance, when resetting your clocks in the fall or spring. Make sure the detectors are installed according to the manufacturer’s instructions. Do not use rechargeable batteries.

Replace detectors that are more than 10 years old, or err on the side of caution and replace them every five years.

Clean the device according to the instructions. Remove and wipe the cover with a damp cloth. Gently vacuum the inside of the alarm. Replace the cover and test the alarm.

Install detectors on each level of your home, including the basement. You might want to install both types of detectors on each floor of the house. The most important location is near the bedrooms to provide early warning when people are asleep.

Develop and practise an escape route to be used in the event of a house fire.

Call the manufacturer’s toll-free number if you have any concerns about your detector.
