4. What is carbon monoxide?
Carbon monoxide is a colourless, odourless and tasteless gas which can barely be
perceived by the human senses. It is generated during the incomplete oxidation
of substances containing carbon, such as wood, charcoal, fuel oil, petrol or gas.
Carbon monoxide kills or harms hundreds of people every year. It binds the
haemoglobin in the blood and reduces the amount of oxygen in the body. In high
concentrations, carbon monoxide can poison a person within minutes.
