I was told that when a car is catching fire, it is much more dangerous with an empty gasoline tank, than a full tank. The car with the full tank will burn. The car with the empty tank will go:Contrary to what we’ve all assumed (including me)…..studies show it is not easy to the point of being unlikely (not impossible) for a cigarette to ignite gasoline. In fact outdoors it’s nearly impossible. It’s a combination of the narrow flammable range, an ignition temp around 500 f, and how quickly the temperature of that glowing end of the cigarette drops below the ignition temp of gasoline if the cigarette is not being inhaled or drawn in. Notice how when someone pulls on the cigarette the tip brightens and how quickly it darkens. Gasoline is much more dangerous as an accelerant than as the primary ignition source.
This is contrary to everything we’ve “learned” and assumed over the years including my industry. I guarantee you 9 out of 10 firefighters will tell you a cigarette is likely to ignite gasoline.
Is that true?
