Well, I like to keep them in a nice sunny spot with a protective magnifying glass overhead (don't want those cans rusting....)
:P
If you're going to have more than a couple of gallons of fuel in your camp BM has some rules.

-Any collection of 20 gallons or more of flammable liquid must be kept within a secondary containment area. The containment method can be as simple as a petroleum resistant tarp rolled up to provide a berm.
-A supply of cat litter or fuel absorbent should be kept on hand near any spills basin.
-All containers for liquid fuels must be clearly labeled identifying contents and hazards. Original labels are preferred.
-A safety perimeter of 30 feet must be maintained between liquid fuel containers and any camping area, and clear access must be provided for the BRCFD in case of fire.
-A sufficient amount of dry chemical fire extinguishers must be kept visible and available near the storage location of any liquid fuel.
