Will Burning Candles Produce Carbon Monoxide?

Burning Candles
Do candles produce carbon monoxide when burning?

Is it dangerous to have like 5 candles burning for hours and hours in a room that has closed windows and doors?



Yes, the amount of Oxygen that can take part the combustion process is limited by the large size of the molecules of the wax vapor and the flame size.
And, due to the small flame, the amount of CO is extremely small and poses no hazard in normal use of a candle.
(Carbon (as ‘Soot’) in the smokey flame is also produced).

If you are in a tightly closed room with 5 candles burning over a long period of time, not only will the CO build up, CO2 will also accumulate at the floor level and the Oxygen content of the room will be depleted.
