If the power goes out or mother nature forces you to evacuate you may need an emergency supply of gasoline. Extra gas will keep your generator running or keep your vehicle running when the gas stations go dry. The following will discuss how to safely store an extra supply of gasoline.
For safe storage you will need an UL listed and FM approved gasoline safety can. These cans will be made from heavy galvanized steel. Important features include:
- galvanized steel construction resistant to physical abuse
- full handle allow easy pouring and carrying heavy load
- positive pressure relief cap vents automatically to prevent rupture or explosion in case of fire
- spring loaded self closing lid prevents spills and controls vapor
- internal flame arrestor prevents flashback ignition
Choose between the type 1 and type 2 safety cans. Type 1 cans have one opening for pouring/filling. Type 2 cans have one spout with a flexible metal hose for filling and a separate opening for filling. Type 1 cans will be less expensive.
Cans should be filled to 95% of capacity. This will allow room for the gasoline to expand due to higher temperatures.
If you plan to store the gasoline for more than a few months you should add a preservative such as Sta-Bil. Add the preservative to the fresh gasoline when the tank is filled. The makers of Sta-Bil state their product will preserve gasoline for 12 months or, if you double the dose, two years. Preservatives will NOT restore spoiled gasoline.
Do not store gasoline in or near the house. The gasoline should be stored in a separate well ventilated area with no electrical equipment or open flames.
