9. LIMITATIONS OF CARBON MONOXIDE ALARMS

Carbon monoxide alarms are devices that can provide an early warning of the
presence of CO gas at a reasonable cost. However alarms have sensing limitations
and may not always sound a warning in the presence of CO. The alarm will not operate
if the battery power is low or dead. CO alarms must be tested regularly to ensure that
they are receiving power and operating properly. Carbon monoxide alarms cannot
sense CO that does not reach the alarm, and therefore CO alarms may not detect CO
which is in another area of the home. Furthermore if the alarm is located on a different
level of the home or on the other side of a closed door it may not waken a sound
sleeper. The use of drugs and alcohol may impair ones ability to hear the alarm. If you
have a multi-level home, install CO alarms on each level of the home. If the alarm is
installed in a hallway and the bedroom doors are kept closed at night, install a CO alarm
in each bedroom.
Although CO alarms can help save lives by providing an early warning to the
presence of carbon monoxide, they are not a substitute for an insurance policy.
Homeowners and renters should have adequate insurance to protect their lives and
property.
DO NOT RE-ENTER YOUR HOME FOR ANY REASON UNTIL
CLEANING YOUR ALARM
