Long Term Storage of gasoline

Gasoline is an item that more people are starting to store, due to the rapid increases in price.  This post is to give you some safety tips to keep you from burning your home down or killing yourself.  Most of the information in mere common sense, but every year homes burn down, and people die from lack of it.

  • Do not store gasoline in your house, this includes attached garages.
  • Gasoline should be stored in a separate well ventilated area.
  • It should not be stored near electrical equipment or open flame. Remember a pilot light is an open flame.
  • A secure metal storage cabinet or box located a safe distance from your home is preferred method.
  • Gasoline should be stored in UL or State Fire Marshal approved containers.
  • Currently there are both metal and plastic approved cans on the market.
  • Cans should only be filled to 95% capacity to allow for expansion in hot weather.
  • Check with your local fire department to see how many gallons you may store legally.  Stay within your local fire regulations.

If you plan to store the gasoline for more than a few months you should add a preservative such as Sta-Bil or Pri-G.  Add the preservative to the fresh gasoline when the container is filled. The makers of Pri-G claim that with periodic pretreatments fuel can be stored indefinitely.

Remember that gasoline is a highly flammable liquid and that the vapors are heavier than air and will spread on the ground.  Do not under estimate it’s potential to hurt you.

In a few days I will do a post on military Jerry cans for the storage of flammable liquids.

    I have used Pri-G very successfully storing fuel for 3+ years. It seems to lose some of the btu’s so engines do not quite run at full power but they start quickly and run efficiently. I use abut 1 teaspoon per gallon of gasoline and usually add a teaspoon of a very light lubricant like the Lucas fuel treatment.

    …Really? I’d say that 100% of everybody already does that. Every vehicle has an attached gas tank which is sealed with a rubber gasket, just like gas cans utilize. Therefore, not storing gasoline inside your attached car garage is impossible — at least, if you’re using the garage for its intended primary purpose (storing vehicles when you’re not using them).

    The gasoline tank in your car is a much safer place to store gas than in misc cans. It won’t get knocked over, is much less likely to leak and is sealed better than most gas cans.

    Attached garages are not a great place to store fuel cans either. While building and fire codes vary, I would not be comfortable in a bedroom over an enclosed garage. Recommended practice is that an attached garage have not less than 1 hour fire separation from the rest of the dwelling. In general terms, that requires 4 inches of solid masonry or 1-1/2″ of gypsum board. Your local building official or fire marshall is the best source for current code information for your state.
