Can a cigarette butt ignite petrol?

Answer 1

no. it cannot.

they had this question in Mythbusters, because, in the movies are often gas stations that explode through a cigarette thrown in petrol. It simply would be extinguished. whats dangerous with petrol are the gasses, they can be ignitet really fast.

Answer 2

Not an experiment to try lightly, but usually a cigarette will not ignite gasoline as you see in the movies. An open flame is usually required. This doesn't mean that you should smoke and handle gas at the same time since sometime a cigarette will ignite gasoline.

Answer 3

Anything hot can ignite gasoline, but only the vapor form will combust. So in most cases, a lit cigarette thrown into a pool of gasoline will be extinguished by the liquid. However, ignition of the vapors can occur far from the actual liquid, so for this reason smoking around gasoline is extremely hazardous.

Answer 4

You're on the right tracks, but not quite. Carbon Monoxide is the gas that comes out of a vehicle's exhaust (Which of course you need fuel for this to happen). This gas is also added to many known cigarette products.

Answer 5

If the cigarette is just burning normally, no. But if there is an impurity that causes a tiny spark, there could easily be ignition if the mixture of gasoline vapor and air is just right.

Answer 6

If they're still burning they can catch other things on fire.

Answer 7

No
