alarms. It should be marked to EN 50291 and also have the
British Standards' Kitemark or another European approval
organisation's mark on it. CO alarms usually have a battery life of
up to 5 years.
Fit an alarm in each room with a gas appliance. Always follow
the alarm manufacturer’s instructions on siting, testing and
replacing the alarm.
Do not use the ‘black spot’ detectors that change colour when
carbon monoxide is present, they don’t make a sound. It is

asleep, or you may not be aware of early CO
symptoms until it is too late.
