Carbon monoxide – what do you need to know?

September 15, 2021

This year's Gas Safety Week is running from 13 - 19 September


What is carbon monoxide?

Carbon monoxide (CO) is a poisonous gas that has no taste, colour or smell. It can make you feel
seriously ill and can kill quickly without warning.

What are the signs of a carbon monoxide leak?

Carbon monoxide can be produced when poorly maintained, incorrectly fitted or badly repaired appliances do not burn gas completely.

Look out for the following signs that could indicate that a gas appliance is not working correctly, and CO may be present in the house:

• Floppy yellow or orange flame on your gas hob, rather than a crisp blue flame
• Dark, sooty staining on or around gas appliances
• Pilot lights that frequently blow out
• Increased condensation inside windows

What are the physical symptoms of carbon monoxide poisoning?

If you're suffering from any of the symptoms and feel better when you leave the house, it could be
CO poisoning. If you're concerned you or someone in your household may be suffering from carbon
monoxide poisoning, make sure you do the following:

✓ Get fresh air immediately
✓ Open all doors and windows, switch off gas appliances and leave the house
✓ Contact your GP, who can check and advise if you need treatment for carbon monoxide
poisoning
✓ If you're concerned there is immediate danger, call the gas emergency helpline on 0800 111
999 (mainland GB), 0800 002 001 (Northern Ireland) or look up the number for your UK
region at http://bit.ly/gasemergency.

How to stay gas safe

• Ensure your gas appliances are checked annually by a qualified Gas Safe registered engineer
• Fit an audible carbon monoxide alarm marked EN 50291 which carries the British Standards
Kitemark
