All fuel should be treated as if it were very volatile.
Store fuel in an isolated area that is downhill and down wind from other buildings.
Liquefied petroleum (LP) gas tanks should be left out in the open (no enclosure).
Liquid fuel tanks should be stored in a well-ventilated building.
A fire extinguisher should always be near the stored fuel area.
Electrical fixtures should be sealed from the fuel vapors.
Always shut down the machine before fueling it.
Clean up any fuel spills.
Only use the approved fuel types for your appliances and storage containers.
If you are going to store gasoline, it needs to be treated with a butylated hydroxytoluene (BHT) additive like Sta-Bil and shielded from moisture.
For #2 diesel, you need to add 10% gasoline or 20% kerosene in order to prevent “fuel freezing”—the precipitation of the paraffin at low temperatures.
Ethanol should be stored in a sealed container to prevent moisture contamination.
A general rule of thumb is to monitor your fuel usage for 90 days and keep a supply large enough to last you this period of time.
Kerosene burning appliances are safer than LP gas appliances.
If you are storing diesel fuel, it needs to be treated with a biocide such as methanol or diesel Sta-Bil right after delivery. It should also be filtered before use.
