Follow our six-point plan to keep your family safe when your carbon monoxide detector’s alarm goes off.
When your carbon monoxide alarm goes off, there are key steps to take to make your home safe, and to protect yourself and your family fast.
Open all doors and windows
The first task is to open all of the doors and windows in the house to try to clear some of the deadly gas.
Turn off all fuel-burning appliances and leave the house
Once you’ve done what you can to ventilate your home, turn off all of your fuel-burning appliances, such as boilers and fires, and leave the house. Regardless of whether you feel ill or well, remain outside until you’ve spoken to a doctor or called the emergency advice line.
Don’t switch on the lights, smoke or strike a match
Once the alarm has sounded, if there are gas appliances in your home you should avoid switching on the lights, smoking or striking a match (to light a candle for example).
Seek medical advice
If you feel ill or exhibit any of the symptoms of carbon monoxide poisoning after your alarm goes off, contact your doctor immediately or call 999 for an ambulance.
Call the emergency advice line
If you believe your carbon monoxide emergency was caused by a gas appliance, call the Gas Emergency Service on 0800 111 999. If you use oil to heat your home, call Oftec on 01473 626 298.
Arrange to have your appliances serviced
If your boiler, heater, stove or fire is producing dangerous levels of carbon monoxide, there’s something wrong with it, and it will need to be serviced by a professional.
