Smoke Alarms - Facts and
Advice
Smoke
alarms are the residential fire safety success story of the past quarter
century. Smoke alarm technology has been around since the 1960s. But
the single-station, battery-powered smoke alarm we know today became
available to consumers in the 1970s, and since then, the home fire death
rate has been reduced by half. NFPA estimates that 94% of U.S. homes
have at least one smoke alarm today, and most states have laws requiring
them in residential dwellings.
Facts
& Figures
- 15 of every 16
homes (94%) in the U.S. have at least one smoke alarm.
- One-half of home
fire deaths occur in the 6% of homes with no smoke alarms.
- Homes with smoke
alarms (whether or not they are operational) typically have a death
rate that is 40-50% less than the rate for homes without alarms.
- In three of every
10 reported fires in homes equipped with smoke alarms, the devices did
not work. Households with non-working smoke alarms now outnumber those
with no smoke alarms.
- Why do smoke alarms
fail? Most often because of missing, dead or disconnected batteries.

Install
at least one smoke alarm on every floor of your home (including the
basement) and outside each sleeping area. If you sleep with the door
closed, NFPA recommends installing smoke alarms inside the room. In
new homes, smoke alarms are required in all sleeping rooms, according
to the NFPA 72, National Fire Alarm Code®.
-
Mount
the smoke alarms high on ceilings or walls remember, smoke
rises. Ceiling-mounted alarms should be installed at least four inches
away from the nearest wall; wall-mounted alarms should be installed
four to 12 inches away from the ceiling. On vaulted ceilings, be sure
to mount the alarm at the highest point of the ceiling.
-
Don't
install smoke alarms near windows, outside doors, or ducts where drafts
might interfere with their operation.
-
Don't
paint your smoke alarms; paint or other decorations could keep them
from working when you most need it.
Maintenance
Tips
- Test smoke alarms
at least once a month by using the alarm's "test button" or
an approved smoke substitute, and clean the units in accordance with
the manufacturer's instructions.
- Replace the batteries
in your smoke alarms once a year, or as soon as the alarm "chirps,"
warning that the battery is low. Hint: schedule battery replacements
for the same day you change your clock from daylight to standard time
in the fall.
- Regularly vacuuming
or dusting your smoke alarm following manufacturer's instructions can
help keep it working properly.
Replace your smoke alarms once every 10 years.
- Never "borrow"
a battery from a smoke alarm.
- Make sure that
everyone in your home can hear and recognize the sound of the alarm
and knows how to react immediately.
- NFPA recommends
that people with hearing impairments install smoke alarms with louder
alarm signals and/or strobe lights to alert them to a fire.
- Be sure that the
smoke alarm you buy carries the label of an independent testing lab.
For a list of manufacturers that distribute smoke alarms for the hearing
impaired, please call NFPA´s Center for High-Risk Outreach at
+1 617 984-7826.
- Alarms that are
hard-wired to the home's electrical system should be installed by a
qualified electrician.
