A burning pan, especially one that is overheating or has food burning in it, can potentially produce carbon monoxide (CO). However, the amount of CO produced from a burning pan is generally low compared to other sources, such as a malfunctioning gas stove or a vehicle exhaust. The primary concern with a burning pan is the production of smoke, which may contain other harmful compounds.
If you had windows and doors open while the pan was burning, it is likely that sufficient ventilation was provided. Adequate ventilation helps disperse any smoke and potentially reduce the concentration of CO and other byproducts. Opening windows and doors is a good precautionary measure to improve air circulation and remove any smoke or fumes from your living space.
However, it is important to note that even with ventilation, it is still advisable to exercise caution and take steps to prevent burning or overheating pans. Unattended or excessively overheated pans can lead to fire hazards and the release of smoke and potentially toxic substances. It is best to monitor your cooking closely and take immediate action if you notice a pan starting to burn or produce excessive smoke.
If you have any concerns about the air quality or potential exposure to CO or other harmful substances, it is recommended to consult a local authority or a professional who can assess the situation based on the specifics of your situation. They can provide you with appropriate guidance and ensure your safety.
