Carbon monoxide (CO)

Advice and guidance on carbon monoxide (CO), and the prevention, diagnosis and treatment of CO poisoning.

Carbon monoxide (CO) is a colourless, odourless and tasteless gas, produced when fossil fuels such as gas, coal, coke and oil and other fuels burn without enough air.

Exposure to high indoor levels can be fatal, while exposure to lower levels can result in symptoms that resemble flu, viral infections or food poisoning.
