Why do these things always group different fuel types into the same law? The hazards associated with gasoline and gasoil are very different, the flashpoint is no where near the same, and so the risk is not the same. A blanket law to cover all fuels it seems. Cooking oil, by the way, has a much lower flashpoint, and auto-ignition temperature than gasoil, and while maybe not used widely in residential properties, is easily bought in 50l drums. Not as tasty to eat though, diesel isn't.
