CO – The Silent Killer

Carbon Monoxide (CO) is a chemical compound of carbon and oxygen. It is a colourless, odourless gas, and is poisonous to all warm-blooded animals and to many other forms of life.

While the products of complete combustion are not toxic, they will rapidly cause asphyxia if allowed to build up in an enclosed space as they replace the breathable oxygen. This should be taken into account when investigating reports of “fumes”, as products of complete combustion will not generally show up on a single cell analyser designed to detect CO only.

Fire Facts (UK Fire Service Resources)

Every year the Fire Service are called to over 600,000 fires which result in over 800 deaths and over 17,000 injuries.

About 50,000 (140 a day) of these are in the home and kill nearly 500 and injure over 11,000, many which could have been prevented if people had an early warning and were able to get out in time.
