Carbon Monoxide has no colour, smell or taste and cannot be detected by the human senses.
It is also extremely dangerous, binding itself to the haemoglobin in red blood cells and preventing them from transporting oxygen around the body.
The immediate reaction to anyone experiencing the potential symptoms of Carbon Monoxide poisoning should be to get them outside and into fresh, clean air.
Stay out of the building, warn neighbours and call for help.
Fitting Carbon Monoxide detectors in your house ensures that you are warned if the deadly gas is present. A detector should be placed in rooms where CO could be produced.
So, you've fitted a detector near your boiler, you've had your appliances checked by an engineer, you're safe right? Wrong.
Carbon Monoxide can seep through walls making it essential that your neighbours also understand the risks.
