With a nod to the Propane thread, I am good with the 20lb propane
tanks and never bring them inside- but in my well ventilated and
unheated, but electrified garage I have;
in the winter a car with 12gallons of gasoline-
a generator with 10gallons of gas
a 5gallon and two 2 gallon cans of gas
two 1 gallon cans of mixed gas [40:1 & 50:1]
5 gallons of kerosene
5 gallons of diesel

I have toyed with the idea of a dedicated fuel shed/box out back but
it isn't something I've ever gotten around to. What are some
thoughts on safe storage of all this crap?
