What makes fuels and solvents dangerous?
Gasoline and many solvents give off vapors that can ignite from a spark, a pilot light or hot equipment, often some distance from the container. The vapors can also make people dizzy or ill when breathed in a closed space.
Diesel is less volatile but still burns. Treat all of them with respect.
Vapors are often heavier than air and can collect low to the ground, in pits and in corners. A pilot light or an electric spark far from the source can ignite them.
- Fire and explosion from vapors
- Dizziness and headaches from fumes
- Skin irritation
- Soil and water contamination
How should fuel be stored?
Use containers made for fuel and labeled for the type, kept closed and away from living spaces, heat and ignition sources. Store small amounts outdoors or in a separate, ventilated building. Local fire codes can limit how much you may store, so ask your fire department or county for current rules.
Keep fuel away from children, and never use food or drink bottles.
Check with your local fire department about how much fuel you may keep and where. Rules differ by place and are sometimes stricter than people expect.
How do you transfer fuel safely?
Turn engines off and let hot equipment cool before refueling. Do not smoke or work near open flame. Fill containers on the ground rather than in a truck bed so static does not build up, and avoid overfilling.
Wipe up small spills at once and keep rags in a covered metal container while they dry, since oily rags can heat up and ignite.
Static electricity can ignite fuel vapors during filling. Setting portable containers on the ground, keeping the nozzle in contact with the opening and filling slowly all reduce the risk.
- Engine off and cooled
- No smoking or sparks
- Fill portable cans on the ground
- Do not overfill
How do you use solvents safely?
Work outdoors or with strong ventilation. Wear chemical-resistant gloves and eye protection, and check the label for any respirator guidance. Keep solvent away from heaters and welding.
Never use gasoline to clean parts or start fires. It is far more dangerous than products designed for those jobs.
Keep solvent containers tightly closed and away from sunlight. Label any transferred product, and discard rags in the way the label or your fire department recommends.
What if there is a fire or spill?
For any fire you cannot put out right away, get everyone out and call 911. Keep a suitable fire extinguisher near the shop and fuel areas, and ask your fire department which type fits your setup and how to use it.
For a spill, remove ignition sources, ventilate, absorb with suitable material and do not wash it into drains. Call your local emergency office for large spills.
An extinguisher helps only if you know how to use it and you are not too close. Get everyone out first, call 911, and fight a fire only when it is small and your exit is clear.
What about fuel tanks and old fuel?
Bulk tanks may be covered by state or local rules on placement, spill containment and registration. Check with your state environmental or agriculture agency before installing one.
Old fuel and used solvent cannot just be poured out. Ask your county solid waste office or a local collection program how to dispose of them.
Fuel in the wrong place can reach groundwater. Keep tanks and containers away from wells, ditches and streams, and ask your state agency about rules for containment.
How do you respond to fume exposure?
Move the person to fresh air right away. If they feel dizzy, confused, short of breath or faint, call 911 or poison control. Do not go into an enclosed space where someone has collapsed unless you can do so safely, since you could be overcome too.
Afterward, find and fix what caused the exposure.
Headaches, dizziness or nausea during solvent work mean you need more air. Stop, step outside and fix the ventilation before you go back.
- Get to fresh air
- Call 911 for severe symptoms
- Do not enter a fume-filled space alone
- Ventilate before returning
Key takeaways
- Fuel vapors ignite easily and fumes harm health.
- Use approved containers, store away from ignition sources and living areas.
- Shut off, cool down and ground containers when fueling.
- Ventilate when using solvents and never use gasoline for cleaning.
- Ask your fire department and county about storage rules and disposal.
