Carbon Monoxide Risks

What is carbon monoxide?


Sweeping helps prevent carbon monoxide problems

You can’t see it, taste it or smell it , but it can kill quickly and with no warning.


Carbon monoxide (CO) is a highly poisonous substance produced by the incomplete burning of gas and Liquid Petroleum Gas (LPG).

This happens when a gas appliance has been incorrectly fitted, badly repaired or poorly maintained. It can also occur if flues, chimneys or vents are blocked.

Oil and solid fuels such as coal, wood, petrol and oil can also produce carbon monoxide.


Remember the six main symptoms to look out for:

    1. headaches

    2. dizziness

    3. nausea

    4. breathlessness

    5. collapse

    6. loss of consciousness

Being aware of the symptoms could save your life.

Carbon monoxide symptoms are similar to flu, food poisoning, viral infections and simply tiredness. That’s why it’s quite common for people to mistake this very dangerous poisoning for something else.

Other signs that could point to carbon monoxide poisoning:

    • Your symptoms only occur when you are at home

    • Your symptoms disappear or get better when you leave home and come back when you return

    • Others in your household are experiencing symptoms (including your pets) and they appear at a similar time

What should I do if I experience any symptoms of carbon monoxide poisoning?

    • Get fresh air immediately. Open doors and windows, turn off gas appliances and leave the house

    • See your doctor immediately or go to hospital - let them know that you suspect carbon monoxide poisoning. They can do a blood or breath test to check

    • If you think there is immediate danger, call the Gas Emergency Helpline

    • Get a Gas Safe registered engineer to inspect your gas appliances and flues to see if there is a dangerous problem
