Carbon Monoxide Poisoning - What is it and what are the symptoms to look out for?
Carbon Monoxide (CO) is a highly poisonous substance produced by the incomplete burning of gas and Liquid Petroleum Gas (LPG). This is usually produced when a gas appliance has been incorrectly fitted, poorly maintained. It can also occur if flues, chimmneys or vents are blocked. You can’t see it, taste it or smell it but it can kill quickly and with no warning. Unsafe gas appliances produce a highly poisonous gas called carbon monoxide (CO). It can cause death as well as serious long term health problems such as brain damage
Remember the six main symptoms to look out for:
- headaches
- dizziness
- nausea
- breathlessness
- collapse
- 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
Don’t assume your gas appliances are safe: get a Gas Safe registered gas engineer to do a check. This is the only safe way to prevent yourself and those around you from incurring serious illness or death due to carbon monoxide exposure.
What is carbon monoxide poisoning?
Carbon monoxide poisoning occurs when you breathe in even small amounts of the gas.
When you breathe in carbon monoxide, it gets into your blood stream and prevents your red blood cells from carrying oxygen. Without oxygen, your body tissue and cells die.
Levels that do not kill can cause serious harm to health when breathed in over a long period of time. Long term effects of carbon monoxide poisoning include Paralysis and brain damage. Such long term effects occur because many people are unaware of unsafe gas appliances and subsequent gas leaks.
How do I avoid a carbon monoxide leak in my home?
Your home may show signs of carbon monoxide. Any one of the following could be a sign that there is carbon monoxide in your home. Get your gas appliances checked to avoid carbon monoxide poisoning.
- The flame on your cooker should be crisp and blue. Lazy yellow or orange flames mean you need to get your cooker checked
- Soot or yellow/brown staining around or on appliances
- Pilot lights that frequently blow out
- Increased condensation inside windows
If you have a faulty appliance in your home, it could lead to carbon monoxide poisoning. Get it checked as soon as possible by a Gas Safe registered engineer.
How do I avoid a carbon monoxide leak in my home?
Because carbon monoxide has no taste, smell or colour. Gas Safe Register strongly recommends you fit an audible carbon monoxide alarm in your home.
A carbon monoxide alarm looks similar to a smoke alarm and is very easy to fit by following the manufacturer’s instructions. You can purchase a carbon monoxide alarm for under £20 at your local DIY store, supermarket or from your energy supplier.
Before purchasing a carbon monoxide alarm, always make sure it is officially approved to EN 50291. It must have a British or European approval mark on it, such as a Kitemark.
You are particularly at risk from carbon monoxide poisoning while sleeping, as you may not be aware of early carbon monoxide symptoms until it’s too late. Do not use the ‘black spot’ detectors that change colour when carbon monoxide is present. These will not make a sound to wake you up if the poisonous gas is present while you are sleeping.
Flues, chimneys and air vents
Flues, chimneys and air vents play a vital role in the safe operating of gas appliances. Flues and chimneys allow products of combustion to escape from your home. Air vents ensure there is a good supply of combustion air (ventilation) to appliances. For this reason you must keep all flues, chimneys and air vents clear.
Shared flues
Do you live in a block of flats or terraced housing? It is also possible for carbon monoxide to seep into properties through shared flues and chimneys. If you live in a property with a shared flue or chimney, share responsibility to get them checked every year to make sure they are allowing gas to escape safely.
