Open the doors and windows to
ventilate the area.
Turn off all fuel appliances where
possible and stop using them. The alarm
can be silenced immediately by pushing
the test/hush button provided the CO
level is <150ppm.
Evacuate the property leaving the doors
and windows open.
Get medical help immediately for
anyone suffering the effects of carbon
monoxide poisoning (headache,
nausea), and advise that carbon
monoxide poisoning is suspected.
Do not re-enter the property until the
alarm has stopped. If the alarm has
been silenced by pressing the test/hush
button, wait at least 5 minutes so the
alarm can check that the CO has cleared.
Do not use the fuel appliances again
until they have been checked by a
registered installer or equivalent expert.
If there is any question as to the cause
of the alarm it should be assumed that
the alarm is due to dangerous levels
of carbon monoxide and the dwelling
should be evacuated.
When ventilation is provided by leaving
the window and doors open, the CO build
up may have dissipated by the time help
arrives and the alarm may have stopped
sounding. Although your problem may
appear temporarily solved it is crucial that
the source of the CO is determined and
that appropriate repairs are made.
Ring your gas or other fuel supplier
on their emergency number. Keep the
number in a prominent place.
Know and look out for tell-tale signs that
carbon monoxide may be present.
These include:
The CO alarm warning of abnormal levels.
Staining or discolouration on or around
appliances.
A pilot light frequently going out.
A strange smell when an appliance is
operating.
A naked gas flame which is yellow or
orange, instead of the normal blue.
Family members (including pets) exhibit-
ing the “flu-like” symptoms of CO poison-
ing described above. If any of these signs
are present, get the appliance checked out
by an expert before further use. If family
members are ill, get medical help.
Choose all appliances and vehicles
which burn fossil fuels such as coal, oil,
natural/bottled gas, paraffin, wood,
petrol, diesel, charcoal etc. with care and
have them professionally installed and
regularly maintained.
These appliances must “breathe in” air
to burn the fuel properly. Know where
the air comes from and ensure vents/air
bricks etc. remain unobstructed (particu-
larly after building work).
The appliances must also “breathe out”
the waste gases (including the CO) –
usually through a flue or chimney. Ensure
chimneys and flues are not blocked or
leaking and get them checked every year.
Check for excessive rust or cracks on
appliances and pipe work.
Never use a gas cooker for home heating.
Never leave your car, motor bike or lawn-
mower engine running in the garage with
the garage door closed. Never leave the
door from the house to the garage open
if the car is running.
Never adjust your own gas pilot lights.
Children should be warned of the
dangers of CO poisoning and instructed
never to touch or interfere with the CO
alarm. Do not allow small children to
press the test/hush button as they could
be subjected to excessive noise when
the CO alarm sounds.
Never use a barbecue grill indoors.
Leaving windows or doors slightly
open (even a few inches) will signifi-
cantly reduce the risk of high levels of
CO occurring.
The high levels of draught-proofing in
modern houses reduces ventilation and
can allow dangerous gases to build up.
Install CO alarms in all the areas recom-
mended in this booklet.

Follow these guidelines to reduce the risk of carbon monoxide poisoning.
