Smoke Detectors
Smoke Detectors Save Lives
The
majority of fatal home fires happen at night, when people are asleep. Contrary to
popular belief, the smell of smoke may not wake a sleeping person. The poisonous
gasses and smoke produced by a fire can numb the senses and put you into a deeper sleep.
Inexpensive household smoke detectors sound an alarm, alerting you to a fire. By
giving you time to escape, smoke detectors cut your risk of dying in a home fire nearly in
half. Smoke detectors save so many lives most states have laws requiring them in
private homes.
Choosing a Detector
Be
sure that the smoke detectors you buy carry the label of an independent testing
laboratory.
Several types of detectors are available. Some run on batteries, others on household
current. Some detect smoke using an "ionization" sensor, others use a
"photoelectric" detection system. All approved smoke detectors,
regardless of the type, will offer adequate protection provided they are installed and
maintained.
Is One Enough?
Every
home should have a smoke detector outside each sleeping area and on every level of the
home, including the basement. The National Fire Alarm Code, developed by NFPA
requires a smoke detector in each sleeping room for new construction. On floors
without bedrooms, detectors should be installed in or near living areas, such as dens,
living rooms, or family rooms.
Be
sure everyone sleeping in your home can hear your smoke detector's alarms. If any
residents are hearing impaired or sleep with bedroom doors closed, install additional
detectors inside sleeping areas as well. There are special smoke detectors for the
hearing impaired; these flash a light in addition to sounding an audible alarm.
For
extra protection, NFPA suggests installing detectors in dining rooms, furnace rooms,
utility rooms, and hallways. Smoke detectors are not recommended for kitchens,
bathrooms, or garages - where cooking fumes, steam or exhaust fumes could set off false
alarms - or for attics and other unheated spaces where humidity and temperature changes
might affect a detector's operation.
Where To Install
Because smoke rises, mount detectors high on a wall or on the ceiling. Wall-mounted
units should be mounted so that the top of the detector is 4 to 12 inches (10 to 30 cm)
from the ceiling. A ceiling mounted detector should be attached at least four inches
(10 cm) from the nearest wall. In a room with a pitched ceiling, mount the detector
at or near the ceiling's highest point.
In
stairways with no doors at the top or bottom, position smoke detectors anywhere in the
path of smoke moving up the stairs. But always position smoke detectors at the
bottom of closed stairways, such as those leading to the basement, because dead air
trapped near the door at the top of a stairway could prevent smoke from reaching a
detector located at the top.
Don't
install a smoke detector too near a window, door, or forced-air register where drafts
could interfere with the detector's operation.
Installation
Most
battery-powered smoke detectors and detectors that plug into wall outlets can be installed
using only a drill and a screwdriver, by following the manufacturer's instructions.
Plug-in detectors must have restraining devices so they cannot be unplugged by
accident. Detectors can also be hard-wired into a building's electrical system.
Hard-wired detectors should be installed by a qualified electrician. Never
connect a smoke detector to a circuit that can be turned off by a wall switch.
False Alarms
Cooking vapors and steam sometimes set off a smoke detector. To correct this, try
moving the detector away from the kitchen or bathroom, or install an exhaust fan.
Cleaning your detector regularly, according to the manufacturer's instructions, may also
help.
If
"nuisance alarms" persist, do not disable the detector. Replace the
detector.
Maintenance
Only a
functional smoke detector can protect you.
Never
disable a detector by "borrowing" its battery for another use.
Following the manufacturer's instructions, test all your smoke detectors monthly and
install new batteries at least once a year. A good reminder is when you change your
clocks in the spring or fall: change your clock, change your battery.
Clean
your smoke detectors using a vacuum cleaner without removing the detector's cover.
Never
paint a smoke detector.
Smoke
detectors don't last forever. Replace any smoke detector that is more than 10 years
old.
Plan And Practice
Make
sure everyone is familiar with the sound of the detectors alarm.
Plan
escape routes. Know at least two ways out of each room. Agree on a meeting
place outside your home where all residents will gather after they escape. Practice
your escape plan at least twice a year.
Remove
obstructions from doors and windows needed for escape.
Make
sure everyone in the household can unlock doors and windows quickly, even in the dark.
Windows or doors with security bars should be equipped with quick-release devices
and everyone in the household should know how to use them.
When
an alarm sounds, leave immediately. Go directly to your outside meeting place and
call the fire department.
Once
your out, stay out. Never return to a burning building.
