Smoke and Carbon Monoxide
(CO) Alarms for Homes
Home Dangers every year nearly
4,000 Americans die in home
fires and approximately 25,000
are injured. Children and the
elderly are especially at risk
in home fires because they are
less able to escape when fire
strikes.
There are a few hundred CO
fatalities annually, and many
more persons suffer flu-like
symptoms from CO exposure. You
can improve the chances that
your family will survive a home
fire or CO leak by installing
smoke and CO alarm s and knowing
what to do if they sound.
Alert your family to danger The
primary fire safety strategy for
any home is to warn the
occupants early and get everyone
out as quickly as possible.
The best way to get the earliest
warning
of danger is by installing
enough smoke
alarms. Homes should have a
smoke
alarm near the bedrooms, but not
so
close to the kitchen that you
have
problems with alarms from
cooking. It’s a
good idea to have a smoke alarm
in
each bedroom, especially if you
sleep
with the door closed.
CO usually comes from faulty
heating
appliances but may also come
from fireplaces or cars running
in attached
garages. CO cannot be seen,
tasted or
smelled, so the only way to
detect a CO
problem is to have a CO alarm.
CO
alarms should be located near
the
bedrooms.
If your smoke or CO alarm
sounds, get
everyone outside.
What kinds are there?
There are two kinds of smoke
alarms --ionization and photoelectric.
The
ionization smoke detectors
activate
quicker for fast, flaming fires
and the
photoelectric type is quicker
for slow,
smoldering fires. Either one
will provide
you enough time to get out, but
having a
mix of the two types is a good
idea.
Models with both sensors are
better than
single sensor units, but of
course they
cost more.
Smoke alarms are powered either
by
household current (ac), a
battery, or ac
with a battery that keeps it
operating
during power outages. The
battery type
is easy to install in existing
homes but
the battery must be changed
annually.
Building codes for new homes
require ac
powered alarms with battery
backup. For
greater safety, older ac only
smoke
alarms should be replaced with
ac/battery alarm, and new codes
requires
any smoke alarm older than 10
years to
be replaced.
Many local building codes now
require
CO alarms when a home uses gas
or oil,
or has a fireplace. CO alarms
are also
powered either by household
current
(ac), a battery, or ac with a
battery. Most
CO comes from equipment that
will not
be working during a power outage so
plug-in units are good. But if
you might
heat your home with a fireplace,
wood
stove, or kerosene heater when
the
power is out, you may want to
use a
battery-powered alarm. The
sensor
element in some CO alarms must
be replaced regularly. Consider
the cost of
the replacement element in
making your
selection.
