So did anyone at the pumps start up their vehicle and drive away before ALL of the spilled fuel was allowed to evaporate or was soaked up and removed? If so, how is this any less dangerous than leaving the fridge on?
The vapor density is defined as the ratio of density of the vapor of a substance to the density of air. Air has a density of one. Substances with a vapor density of less than one are lighter than air and tend to dissipate easily. Substances with a vapor density greater than one are heavier than air and tend to accumulate in low places. Gasoline has a vapor density of 3 to 4. At normal temperatures, liquid gasoline is producing vapors that can catch fire, and which accumulate in low places. These vapors can travel considerable distances from the spill point. If you spill gasoline in the basement or in the garage, the flammable vapors can travel considerable distances and ignite from the pilot light of a hot water heater or furnace. Many building codes require that garage mounted hot water heaters be elevated 18 or more inches above floor level for this reason.
How high off the ground is the pilot light on a RV fridge?
