and CO Detector Safety
In the United
States, 15 of every 16 homes (94%) 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. Smoke alarms most often fail because
of missing, dead or disconnected batteries.
Install, Test and Battery Replacement of Smoke Alarms
1. Install at least one smoke alarm on every floor of your
home (including the basement)
and outside each
Because smoke rises,
alarms should be mounted high on walls or ceilings.
3. Smoke alarms should not be installed near a window, door
or forced-air register where
drafts could interfere
with their operation.
4. Test smoke alarms at least once a month.
5. Install new batteries in all smoke alarms at least once a
year, for example, on your birthday.
6. Replace all smoke alarm batteries immediately upon moving
into a new home.
7. Keep batteries in smoke alarms; do not borrow them for other
8. Replace smoke alarms every 10 years.
