Carbon monoxide (CO) is produced when fossil fuels fail to burn properly, usually because gas appliances are faulty or badly fitted.
According to the Health and Safety Executive (HSE), every year about 36 people die from carbon monoxide poisoning, caused by gas appliances and flues that have not been properly installed or maintained. Many others also suffer ill health. Carbon monoxide is an invisible and highly toxic gas that slowly poisons its victims without them even knowing it – but it can be avoided.
What releases carbon monoxide?
There are a number of ways for carbon monoxide to be released into the home:
- badly fitted, maintained or damaged appliances, e.g. gas boilers, cookers, or water heaters
- poorly ventilated rooms
- blocked chimneys or flues.
Are there any warning signs that carbon monoxide may be present?
Yes, and they include:
- flames in gas appliances burning orange or yellow instead of the usual blue
- sooty stains appearing on or above appliances
- coal or wood fires being difficult to light, burning slowly or going out.
How does carbon monoxide poison you?
Inhaling carbon monoxide allows it to enter your bloodstream through your lungs. Because carbon monoxide is odourless and colourless you won’t even know you’re breathing it in.
What are the symptoms?
The symptoms of carbon monoxide poisoning are easy to mistake for other illnesses such as flu. Be on the lookout for recurring headaches, nausea, dizziness, drowsiness and chest pains.
Who is at risk?
Anyone who is exposed to carbon monoxide is at risk. However, those suffering from health problems, the elderly, children and expectant mothers are likely to be affected much sooner than others.
What to do?
If you are concerned about carbon monoxide, or have found a gas leak, you should call the National Grid Gas Emergency Service on 0800 111 999.
