I do not normally think about how easy it is to ignite gasoline. I know that flame (as from a match) or a single spark can ignite gasoline. Anyway, as I was standing at a gas pump, I started to contemplate the combustibility of gasoline. I do not smoke, but if I did, I would be smart enough not to smoke near the gas pumps. I know from experience that entering and exiting my vehicle generates static electricity. I always stay outside my vehicle when filling and dissipate the stored charge before I get close to my gas tank.
