Carbon monoxide (CO) is a particularly dangerous toxic gas, not only because it has no colour, no taste and no odour but because it is common in populated areas as a result of the burning of fossil fuels in vehicles and heating systems. Despite advances in detection, CO, or ‘the silent killer’ as it is often referred to, is still responsible for tens of thousands of deaths each year.
