I would love for anyone that is conversant with science and logic to detail a method that produces a scenario that is dangerous when refueling that does not include dysfunctional logic. It took several years after Nixon was impeached for the government to ban smoking while refueling. Which horse was in what place in what position regarding which cart at that time? This was long after good science recommended grounding containers, filling small tanks on the ground and not using glass containers. There can be significant static charge developed when pumping fuel. I will continue to operate my fridge while traveling unless directed otherwise while on-board vessels or transiting tunnels.
Well written but maybe not so accurate. Gasoline is a very volatile fast moving gas once released from a container. Air touching the surface naturally rises and carries surrounding gases with it. You cannot detect where It's collecting, or its concentration. If you had an explosimeter handy, by time you had a bad reading, it would be too late.
Diesel oil is nearly as bad, plenty of Internet videos prove this. Just sayin stay safe
