Fuel Storage Safety

Why does fuel storage need extra care on a farm?

Gasoline gives off vapor that is heavier than air and can travel along the floor to a pilot light, a spark from a switch or a hot engine. Diesel is harder to ignite but still burns, and a spill of either fuel can soak into soil and reach a well or stream.

Farms add other risks: fuel kept near hay, dust and old rags, containers left in the sun, children and visitors who wander through the shop, and equipment that is refueled while still hot. Knowing these hazards helps you set up storage that fits the way you actually work.

Keep a short written plan for the whole household. It should say where fuel is kept, where extinguishers are and who calls whom. A plan that everyone knows makes a quick, calm response far more likely.

What kind of containers should I use?

Use containers made and labeled for the specific fuel, with tight caps and a design that suits the fuel you are storing. Do not reuse milk jugs, drink bottles or food containers, which are not built for fuel and can be mistaken for something safe to drink.

Label every container with the contents, and keep gasoline and diesel clearly apart so nobody puts the wrong one in an engine. Replace containers that are cracked, swollen, rusted or leaking, and keep caps and spouts in good condition.

• Approved container for each fuel type
• Clear label on every container
• Tight, undamaged caps and seals
• Separate storage for gasoline and diesel

Where should fuel be stored?

Keep fuel in a detached, ventilated, shaded building or shed away from the house, barn, hay, vehicles and anything that makes sparks or flame. Do not store it in living spaces, attached garages with water heaters or furnaces, or the cab of a truck.

Place containers on a stable, level surface off bare soil, ideally with something to catch drips. Keep the area clear of dry grass and clutter, and keep it locked if children or visitors are around.

Think about what is stored near the fuel. Fertilizer, pesticides, propane cylinders, oily rags and hay all add risk. Keep fuel at a distance from them, and ask your fire department what separation they recommend.

How much fuel can I keep, and do rules apply?

Limits on quantities, container types, distances from buildings and property lines, and permits for larger tanks vary by state, county and town. Insurance companies may have requirements of their own.

Call your local fire department or fire marshal and your county zoning or building office and ask what applies to your property. If you plan an above-ground or underground tank, also ask which environmental agency regulates it and what spill protection is required.

Fuel goes stale. Old gasoline can gum up an engine, and water collects in tanks with condensation. Buy amounts you will use in a reasonable time, rotate your stock and ask a mechanic or the engine maker how long fuel can sit before it causes trouble.

How do I refuel safely?

Shut the engine off and let hot equipment cool before refueling. Fill outdoors, on the ground or a stable surface, not in the bed of a truck with a plastic liner or in a trailer, where static can build up. Keep the nozzle or spout in contact with the tank opening and avoid overfilling.

Wipe up small spills and let the vapor clear before starting the engine. Do not smoke or use phones or open flames nearby. Keep a fire extinguisher rated for fuel fires within reach and know how to use it.

What if there is a spill or fire?

For a small spill, stop the flow if safe, keep ignition sources away, and use an absorbent material, then dispose of it as your local waste or hazardous waste program directs. Do not wash fuel into drains, ditches or the soil.

For a larger spill or any fire that is not tiny and contained, get people and animals away and call emergency services. Report significant spills to the agency your state names. Never store rags soaked in fuel or solvent in a pile, because they can heat and ignite.

What mistakes do farms make with fuel?

Common errors include storing gasoline in the barn next to hay, leaving containers in a hot truck bed, filling a hot engine and keeping old, unlabeled cans. Each is easy to fix with a short weekend of cleanup.

Another is forgetting about children and visitors. Keep fuel locked, tell everyone who works on the place where it is, and what not to do. When you clean out an old can, ask your county waste or hazardous waste office how to dispose of old fuel. Do not pour it on the ground, down a drain or into a ditch.
