Re: Petrol or LPG - Which one is more explosive?
We use LPG at work with our forklifts, because its far cleaner and safer. If a tank or fuel line of LPG were to rupture, it will NOT flash instantly into vapor. You'd have a big pool of very cold steaming LPG on the floor. These tanks have a large relief valve to help prevent rupture of the tank. If you did manage to rupture and tank and want an explosion, the vapor would have to be between the lower explosive limit of 1.8% and the upper explosive limit of 9.5%. If there's no ventilation, the vapor will build and may seek an ignition source for an explosion. If the liquid finds a igntion source immediately, you'd just have a big fireball just like gasoline.
