7. Recommended actions when CO alarm warning has been activated
If your CO alarm is in ALARM, keep calm, and carry out the following actions in the following order:
Open all doors and windows to increase the rate of ventilation.
Stop using all fuel-burning appliances and turn them off where possible.
If the CO alarm continues, then evacuate the premises. Leave the doors and windows open, and only re-
enter the building when the alarm has stopped.
Get medical help for anyone suffering the effects of Carbon Monoxide poisoning, such as headache or
nausea, and advise that Carbon Monoxide inhalation is suspected.
Telephone the gas or other fuel supplier on their emergency number, so that the source of carbon
monoxide emissions can be identified and corrected.
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.
Note: There may be another source of carbon monoxide emission apart from fuel-burning appliances, for
example a large amount of tobacco smoke, town gas or emission from a smouldering fire. Do not use any
combustion appliances until they have been checked by a qualified person.
