4. What to do if the alarm sounds:
WARNING! – Actuaon of your CO alarm indicates the presence of
Carbon Monoxide (CO) which can KILL YOU. WARNING! – Acon of this
device indicates the presence of dangerous levels of CO! CO can be
fatal! If the alarm sounds:
4.1 Keep calm and open all doors and windows to increase
the rate of ventilation. Stop using all fuel-burning
appliances and ensure, if possible, that they are turned off,
e.g. for gas appliances, isolate the emergency control
valve;
4.2 If the alarm continues to be activated, then evacuate the
premises. Leave the doors and windows open, and only
reenter the building when the alarm has stopped. In multi-
occupancy and multi-storey premises, ensure that all the
occupants are alerted to the risk;
4.3 Get medical help for anyone suffering the effects of
carbon monoxide poisoning, and advise that carbon
monoxide inhalation is suspected;
4.4 Telephone the appropriate appliance servicing and/or
maintenance agency or, when necessary, the relevant fuel
supplier on their emergency number or the national Gas
Emergency Service Provider, if appropriate, so that the
source of carbon monoxide emissions can be identified
and corrected. Unless the reason for the alarm is
obviously spurious, do not use the fuel-burning appliances
again, until they have been checked and cleared for use by
a competent person according to national regulations.
