Almost all fuels emit carbon monoxide gas while burning. However, the concentration of carbon monoxide emitted varies from place to place and depends on the oxygen level in the air. Carbon monoxide is a colorless, odorless, and tasteless gas and is often referred to as the silent killer. It has 200 times more affinity to hemoglobin than oxygen and can potentially kill you if inhaled for a prolonged time. Using a camping stove inside tents or enclosed spaces can increase the carbon monoxide concentration leading to carbon monoxide poisoning. It is crucial to light any kind of fire in the open or build a snow wall around to limit emissions to the environment.
