Carbon Monoxide Poisoning

Many people are unaware of the devastating effects of carbon monoxide poisoning. Carbon Monoxide has no colour, smell or taste and cannot be detected by the human senses. It is extremely dangerous, binding itself to the haemoglobin in red blood cells and preventing them from transporting oxygen around the body.


Estimated Number of Deaths Every Year

According to statistics released by the Office for National Statistics, throughout England and Wales, there are an average of over 60 deaths every year due to accidental exposure to carbon monoxide - up to 45% of which occur in the home.
