Test Your Smoke Detector
A working smoke detector cuts the risk of dying in a home fire by nearly 50%. Yet during actual house fires almost 1/3 of the smoke detectors installed in homes failed to operate because of weak or missing batteries. Protect your safety by checking your detector at least once a month.
Have Battery Backup for Hard Wired Smoke Detectors
If your home has smoke detectors wired into the house's electrical system, they should also be tested monthly. Because you'll still need a working smoke detector when the power is out, your house should have battery-operated units as well.
Change The Batteries
Change the batteries in your smoke detectors at least once a year. Choose a date that is easy to remember, such as the day you change your clocks back in the Fall. And, remember that the entire smoke detector must be replaced after 10 years.
Dust Your Detector
Just as you can't smell when your nose is plugged, the smoke detector can't do it's job when clogged with dust particles. Vacuum the face of your smoke detector at least once a year.
