About 3,500 Americans die each year in fires and about 18,300 are injured. Many of them might be alive today if they had only learned what to do if there is a fire. It is very important to have a working smoke alarm with a working battery in your home. If you have that, it greatly lowers your chances of dying in a fire.
Change Your Batteries Yearly
Most smoke alarms need a new battery at least once a year. A good time to change the battery in your smoke alarm is this time of year when you change your clock from daylight saving time to standard time. Doing this will help you remember to change your battery every year at this same time.
Even if you rent, you still need a new battery in your smoke alarm once a year. Talk to your landlord about who is responsible for installing and maintaining your smoke alarm. If you are disabled or an older adult, ask family or friends to help change batteries each year. If you notice that your smoke alarm is 10 years old or older, replace the smoke alarm with a new one.
