What to Do If Gasoline Spills on You

Strip off any gasoline-soaked clothing right away and flush the affected skin with large amounts of water, then wash thoroughly with soap. Those two steps, done quickly, prevent the vast majority of serious outcomes from a gasoline spill. But gasoline is not just smelly and unpleasant; it is a complex mixture of hydrocarbons that can dissolve the skin’s natural oils, cause chemical burns with prolonged contact, and deliver toxic compounds like benzene directly into your bloodstream through your skin. The urgency of cleanup goes well beyond comfort.

Get the Contaminated Clothing Off First

This is the single most important thing you can do, and it is the step people most often skip or delay. Gasoline trapped against your skin by fabric stays in contact far longer than a splash that hits bare skin and begins evaporating. Clinical reports of serious hydrocarbon contact injuries describe patients who developed full-thickness skin loss, comparable to deep burns, after gasoline-soaked clothing remained against their bodies for extended periods.¹ “Extended” here does not necessarily mean hours. Even twenty or thirty minutes of continuous contact with saturated fabric can cause painful irritation and begin damaging deeper layers of skin.

If your pants leg, shirt, or shoes are soaked, pull them off before you do anything else. Do not try to blot or wipe the clothing first. If you are outdoors, move away from any ignition source before undressing, since gasoline vapors are heavier than air and pool near the ground. Put the contaminated clothing in a plastic bag or leave it outside, away from heat sources, until you can deal with it later. Do not throw gasoline-soaked rags or clothing into a washing machine immediately; the fumes inside the drum can ignite.

How to Wash Gasoline Off Your Skin

Once the clothing is off, flush the exposed area with cool or lukewarm running water for at least several minutes. The initial water rinse does the heavy lifting by physically carrying away the bulk of the fuel and diluting what remains. After flushing, wash the area with a generous amount of mild soap or dish soap and water. Clinical guidance for hydrocarbon skin exposure calls for extensive lavage or soaking with water, followed by wound care similar to partial-thickness burn treatment if the skin is visibly damaged.¹

Laboratory testing of various cleansers on petroleum-contaminated skin found that specialized formulations can remove over 99% of crude oil, grease, and tar from skin surfaces.² Most people will not have a specialized industrial skin cleanser on hand at the moment of a spill, but ordinary dish soap works well for casual exposures. Its surfactants are designed to cut through grease and oil, which is essentially what gasoline residue is. Avoid using hot water, which opens pores and can increase absorption of the chemicals still on your skin. Do not scrub aggressively with abrasive materials; gasoline may have already irritated the skin, and harsh scrubbing can break the surface and worsen damage.

After washing, pat the skin dry gently and apply a fragrance-free moisturizer. Gasoline strips the skin’s natural lipid barrier, leaving it dry, cracked, and more vulnerable to infection. If the skin looks red, blistered, or feels numb, skip the moisturizer and head to a doctor.

Why Gasoline Damages Skin

Gasoline is an effective solvent, which is exactly what makes it dangerous to living tissue. It dissolves the lipids that hold your outer skin layers together. A brief splash that gets washed off within a few minutes usually causes nothing more than mild irritation and dryness. But with longer contact, the solvent action strips away the skin’s protective barrier, leading to a chemical burn that looks and behaves much like a thermal burn. In documented clinical cases, patients exposed to gasoline for prolonged periods developed injuries ranging from superficial irritation to full-thickness skin loss requiring surgical treatment.¹

One case in the clinical literature involved a patient who developed severe systemic complications, not just local skin damage, after contact with a hydrocarbon-based solvent. This is unusual for a momentary spill at the gas pump, but it illustrates why the advice to remove clothing and wash immediately is not overcautious. The skin barrier, once compromised, lets the toxic components of gasoline pass through into the bloodstream.

What Absorbs Through Your Skin and How Fast

Gasoline is not a single chemical. It is a blend of hundreds of hydrocarbons, and several of them can cross intact human skin. The one that gets the most attention from toxicologists is benzene, a known carcinogen. In vitro studies measuring benzene penetration through human skin found that it passes through more rapidly than many other small organic molecules, and that gasoline as a solvent vehicle is one of the routes by which benzene enters the body.³

A study that specifically tested how benzene, toluene, and xylenes in commercial gasoline penetrate human abdominal skin found that benzene had the highest permeability of the three. The lag time before benzene began appearing on the other side of the skin was about one hour, with toluene and xylenes taking roughly two hours.⁴ That one-hour lag time is important practically: it means that if you wash gasoline off your skin within the first thirty to sixty minutes, you substantially reduce the amount of benzene that actually makes it into your body. Delay much longer, and measurable quantities begin reaching your blood.

The total amounts absorbed from a single brief exposure are small. The same study found that less than half a percent of the benzene dose applied to skin ended up in the receptor fluid, and toluene and xylenes were absorbed in even smaller fractions.⁴ A single accidental spill at a gas station is unlikely to deliver a dangerous dose. The real concern is for people who get gasoline on their skin repeatedly, such as mechanics, fuel handlers, and others with occupational exposure. Research modeling dermal benzene absorption during regular solvent use found that even at benzene contamination levels below 0.1%, prolonged and repeated skin contact over time can meaningfully increase the risk of leukemia.⁵

Gasoline also contains fuel additives like MTBE (methyl tertiary butyl ether), which absorbs through the skin quickly. In a study where volunteers had diluted MTBE applied to their skin for one hour, blood levels of the chemical peaked roughly five minutes after the exposure ended, and a metabolite called TBA was still detectable in blood 24 hours later.⁶ Again, a single accidental spill is not the main worry here. But the speed of absorption underlines why fast cleanup matters.

The Fire Risk on Your Body

Most people know gasoline is flammable, but fewer appreciate just how easily gasoline vapor ignites, especially when it is evaporating off warm skin and clothing. Gasoline has a very low flash point, meaning the vapors can catch fire at temperatures well below what you would encounter on a warm day. The ignition source does not need to be an open flame. Static electricity generated by something as routine as sliding across a car seat or pulling a sweater over your head can produce a spark sufficient to ignite a gasoline vapor-air mixture.⁷

If gasoline has spilled on your clothing, you are essentially wearing a wick. The vapors form an invisible cloud around your body, concentrated near the ground because they are denser than air. Walking into a house, getting into a car, or approaching any heat source while wearing gasoline-soaked clothing is genuinely dangerous. This is one more reason why removing the contaminated clothing outdoors, before moving to an enclosed space, is the correct first step. If a significant amount has soaked your clothes and you cannot safely remove them outdoors, stay in an open, well-ventilated area and have someone bring you water and a change of clothes.

If Gasoline Gets in Your Eyes

A splash to the face can send gasoline into your eyes, which is acutely painful and can damage the surface of the eye. The response is the same as for any chemical splash: flush the affected eye immediately with clean, lukewarm water for at least fifteen to twenty minutes. Hold the eyelid open and let the water run across the eye from the inner corner outward. Do not rub the eye. If you wear contact lenses, try to remove them during or after the initial flush. After thorough irrigation, seek medical evaluation, because hydrocarbon solvents can cause corneal damage that is not always obvious immediately.

Breathing the Fumes

While you are dealing with gasoline on your skin, you are also inhaling its vapors, and this can cause symptoms on its own. In a poorly ventilated space like a garage, gasoline fumes can quickly reach concentrations that cause headache, dizziness, nausea, and lightheadedness. Higher exposures can cause confusion or loss of consciousness. If you feel dizzy while cleaning up after a spill, move to fresh air immediately. The fumes are the reason emergency guidance consistently advises handling gasoline spills in open or well-ventilated areas.

If the spill happened indoors, such as in a garage or laundry room, open all available doors and windows before you start cleaning. If the space has a ventilation fan that does not produce sparks, turn it on. Do not turn on or off light switches or appliances in a room with heavy gasoline fumes; the electrical arc can ignite the vapors.

When You Need a Doctor

A small splash that you wash off within a few minutes rarely requires medical attention. You should seek care if any of the following apply:

• Visible skin damage: Redness that worsens after washing, blistering, peeling, or skin that feels numb or waxy.
• Large area of contact: If gasoline soaked a large portion of your body or stayed in contact with your skin for more than fifteen to twenty minutes.
• Systemic symptoms: Dizziness, confusion, headache that does not resolve in fresh air, chest tightness, or difficulty breathing.
• Eye exposure: Persistent pain, redness, blurred vision, or tearing after flushing.
• Swallowed gasoline: Even a small amount in the mouth warrants a call to poison control, because the primary danger from swallowed gasoline is aspiration into the lungs, which can cause a severe form of pneumonia.⁸

If someone has swallowed gasoline, do not induce vomiting. Vomiting dramatically increases the chance that gasoline will be aspirated into the airways, which is the most dangerous outcome of ingestion. Call poison control or emergency services instead.

Getting Rid of the Smell

Even after thorough washing, gasoline odor can linger on skin for hours. This is not necessarily a sign that harmful levels of chemical remain; trace volatile compounds trapped in the skin’s outer layers produce a strong smell at concentrations far below any toxic threshold. A second wash with dish soap, followed by rubbing a paste of baking soda and water on the area, can help. Some people find that white vinegar or a citrus-based hand cleaner is effective. Mechanics’ hand cleaners containing pumice are designed for this purpose, though go easy on irritated skin.

For contaminated clothing, washing alone may not remove the odor or the flammability risk. If the item was thoroughly soaked, it is generally safer to discard it. For lightly splashed clothing, air it outdoors for a full day before machine washing. When you do wash it, run the load separately from your other laundry, use a degreasing detergent, and do not put it in the dryer until you are certain the smell is gone. Dryer heat plus residual gasoline is an avoidable fire risk.

Children and Accidental Exposure

Children are more vulnerable to gasoline exposure than adults for several reasons. They have a higher skin surface area relative to their body weight, which means the same skin dose delivers a proportionally larger systemic exposure. They are also more likely to accidentally swallow gasoline, whether from a cup left within reach or by putting gasoline-contaminated hands in their mouths. The primary danger from ingestion in children is aspiration pneumonia, which occurs when gasoline enters the lungs either during swallowing or during vomiting afterward.⁸

If a child gets gasoline on their skin, the cleanup steps are the same as for an adult: remove clothing, flush with water, wash with soap. Be thorough about washing hands, since children are likely to touch their faces and mouths. If a child swallows any amount of gasoline, call poison control immediately and do not try to make them vomit. Even if the child seems fine, the onset of aspiration pneumonia can be delayed, so medical evaluation is warranted.

Occupational Exposure and Repeated Contact

A one-time accidental spill at the pump is a very different situation from daily gasoline contact on the job. For mechanics, fuel station attendants, and industrial workers who handle hydrocarbons routinely, the cumulative effect of repeated dermal absorption matters. Research on dermal benzene absorption found that even with benzene contamination levels below 0.1% in cleaning solvents, the quantity absorbed through the skin over extended periods of regular exposure is enough to significantly raise leukemia risk.⁵ This finding has practical implications: wearing chemical-resistant gloves (nitrile, not latex) when handling fuel, using tools rather than bare hands to clean parts, and washing hands promptly after any skin contact are not excessive precautions. They are directly supported by the toxicology.

The same research noted that the skin should be considered a genuine portal of entry for benzene, not just a secondary route behind inhalation.³ Workplace safety guidelines have historically focused on airborne benzene limits, but dermal exposure can contribute a meaningful additional dose that is not captured by air monitoring. If you work with gasoline or hydrocarbon solvents regularly, protecting your skin is just as important as ventilation.
