Carbon monoxide (CO) is a colourless, odourless, tasteless, poisonous gas produced by incomplete burning of carbon-based fuels, including gas, oil, wood and coal.
Although carbon-based fuels are safe to use, excess CO is produced when the fuel does not burn properly.
When CO enters the body, it prevents the blood from delivering oxygen to cells, tissues, and organs.
You can’t see it, taste it or smell it but CO can kill quickly without warning. Every year around 15 people in the uk die from CO poisoning caused by gas appliances and flues that have not been properly installed, maintained or that are poorly ventilated. Levels that do not kill can cause serious harm to health if inhaled over a long period. In extreme cases paralysis and brain damage can be caused as a result of prolonged exposure to CO.
Early signs of CO poisoning mimic flu like symptoms and include:

Fit Carbon Monoxide alarms in any room in which there is an appliance. A good sweep will be able offer advice on this.
