Flammable Liquid Storage

Fuels and solvents are part of daily farm work, and they are also a major fire risk. This guide covers storage in general terms and sends you to the fire marshal and official sources for the specific rules.

Why do flammable liquids need special storage?

Fuels and many solvents give off vapors that can ignite from a spark, a hot surface or a flame. The vapors can travel along the ground to a source of ignition some distance away.

That is why safety guidance focuses on keeping vapors, ignition sources and people apart. The details differ by liquid, so read the label and safety data sheet for each one. Write down what you decide and share it with everyone who works on the place.

What kinds of containers should be used?

Use containers and tanks that are made for the liquid and are in good condition. Keep them labeled, closed and upright, and replace any that are damaged, rusted or leaking.

Do not store fuel in food or drink containers, and never use a container that once held another chemical unless a qualified source says it is suitable. Child-safe, clearly labeled containers matter in a home with young people.

Mixing the wrong fuel into a container, a tank or a piece of equipment can damage the machine and create unsafe conditions. Label every container with what it holds, and follow the equipment manual for the type of fuel to use. When a container has been sitting for a long time, ask your supplier about safe disposal instead of pouring it out or mixing it with fresh fuel.

• Use approved, labeled containers in good condition.
• Keep lids closed and containers upright.
• Never reuse food or drink containers for fuel.

Where should flammable liquids be kept?

Storage belongs away from the house, away from ignition sources and away from places where people sleep, cook or work with heat. A separate building or a purpose-built cabinet often makes more sense than a corner of the shop.

Rules about distances, tank placement and cabinets are set by fire codes and local authorities. Contact your fire marshal or state agency before you buy or move a tank, and do not rely on advice from memory.

How can ignition sources be kept away?

Keep welding, grinding, smoking and open flame away from fuel storage and away from places where fuel is handled. Static electricity, hot engines and electrical equipment can also ignite vapors.

Turn engines off before fueling, take your time, and avoid filling containers in places where vapors cannot spread out. Manufacturer manuals describe the proper way to handle each piece of equipment.

What housekeeping steps help?

Wipe up small drips, keep rags in an approved way as your fire department advises, and clear away clutter, dry grass and trash around storage. Do not allow oily rags to pile up.

Walk through the area regularly and check for leaks, damaged hoses and fittings, and signs of tampering. Keep an extinguisher nearby, and make sure people know where it is and that it is serviced as its maker directs.

What if there is a spill or fire?

This site does not give firefighting instructions. If there is a fire, a large spill or anyone is hurt, get everyone away and call 911.

Afterward, talk with your fire department and your insurance agent. Review what happened, change what needs changing and write it down.

Make sure every adult on the farm knows where the nearest phone signal is strong, and keep the farm address posted near fuel storage so a caller can give it quickly.

How should fuel be handled around children and workers?

Keep fuel locked away from children, and teach everyone who works on the farm that fuel is for engines only. It should never be used to start fires, clean hands or clean tools.

Show new workers where fuel is stored, how it is handled, and who to ask if they are unsure. A short walk-through at the start of the season takes only minutes and prevents many mistakes. Insurance companies and fire departments often have practical advice on tank placement, containers and signage, and many will offer it for free. Ask before you install anything new, because moving a tank later costs far more than a phone call now.

• Lock storage and keep keys with trained people.
• Never use gasoline for cleaning or to start fires.
• Cover fueling habits in every worker orientation.
