Common Carbon Monoxide Alarm Going Off questions

What should I do if my CO alarm goes off?

Open doors and windows, turn off gas appliances if safe, get outside and ring 0800 111 999.

Why is my carbon monoxide alarm beeping?

A short chirp every minute or so is usually a low battery or the alarm reaching the end of its life.

What are the symptoms of carbon monoxide poisoning?

Headache, dizziness, nausea, tiredness and breathlessness, often easing when you go outside.

How long do CO alarms last?

Most last around seven to ten years. Check the replacement date on the back.

Can my boiler cause carbon monoxide?

Yes, if it is not burning properly or the flue is blocked or damaged. An annual service checks this.

Do you check gas appliances after an alarm?

Yes, once the supply has been made safe, across Birmingham.

If your carbon monoxide alarm goes off, treat it as real until it is proven otherwise. Open doors and windows, turn off gas appliances if it is safe to, get everyone outside into fresh air, and ring the National Gas Emergency line on 0800 111 999. If anyone feels unwell, with headache, dizziness, sickness or drowsiness, get medical help. Carbon monoxide has no smell or colour, which is why the alarm matters.

Carbon monoxide comes from fuel that is not burning properly. In Birmingham homes the usual sources are a boiler with a blocked or damaged flue, an old gas fire in a front room chimney, a back boiler behind a fire in an older terrace, or a cooker used to heat a room. Blocked chimneys and flues in the Victorian terraces of Handsworth, Sparkhill and Moseley are a known risk, especially where a fire has not been swept or checked for years.

An alarm that beeps briefly every minute or so is usually a low battery or the end-of-life warning, not an alarm. Check the label: most alarms last around seven to ten years and show a replacement date. A continuous loud alarm is the real warning and needs the steps above.

Once the emergency service has made the supply safe, the appliance that caused it must be checked and repaired by a Gas Safe registered engineer before it is used again. We check flues, combustion and ventilation and tell you plainly what we find.

If a carbon monoxide alarm sounds, open doors and windows, turn off gas appliances if it is safe to, get everyone outside and ring the National Gas Emergency line on 0800 111 999.
