Fires produce carbon dioxide (CO2) as one of their primary gases. When organic materials combust, they undergo a chemical reaction that includes the release of heat, light, water vapor, and carbon dioxide. The amount of CO2 produced can vary depending on the type of material burning and the conditions of the fire, such as oxygen availability. In addition to carbon dioxide, fires may also generate other gases such as carbon monoxide, volatile organic compounds, and particulate matter. Understanding these emissions is crucial for both environmental science and fire safety management.
