Install smoke detectors. WORKING SMOKE DETECTORS can alert
you to a fire in your home in time for you to escape, even if you're sleeping. Install
smoke detectors on every level of your home, including the basement, and outside
each sleeping area. If you sleep with the door closed, install one inside your sleeping
area as well.
Test detectors every month, following the manufacturer's directions, and replace
batteries once a year, or whenever a detector "chirps" to signal low battery power.
Never "borrow" a smoke detector's battery for another use - a disabled detector
can't save your life. Replace detectors that are more than 10 years old.
