Gasoline SDS: Hazards, Exposure Limits, and Employer Duties

A gasoline Safety Data Sheet is the OSHA-required document that lists every hazard, exposure limit, first aid step, spill procedure, and storage rule for gasoline in the workplace. It follows a fixed 16-section format under OSHA’s Hazard Communication Standard, and employers must keep a current copy accessible to every worker who may be exposed to fuel during their shift.¹ Gasoline qualifies as a hazardous chemical on multiple fronts: it is extremely flammable, contains cancer-causing benzene, and produces vapors that can overwhelm a person in an enclosed space within minutes.

What the 16 Sections Cover

OSHA’s Appendix D to the Hazard Communication Standard locks in the order and content of every SDS, so a gasoline sheet from one supplier reads the same way as one from another.² The consistent layout matters when a worker or a first responder needs an answer fast.

Sections 1 through 3 identify the product and supplier, state the hazard classifications and signal word, and list every hazardous ingredient with its CAS number and concentration range.
Sections 4 through 6 cover first aid, fire-fighting techniques, and spill response.
Sections 7 and 8 give handling and storage practices along with exposure limits and required personal protective equipment.
Sections 9 through 11 describe physical and chemical properties, stability and reactivity, and toxicological effects.
Sections 12 through 16 address ecological impact, disposal, transport, regulatory status, and other data. OSHA treats 12 through 15 as non-mandatory because other agencies regulate them, but most gasoline SDS documents include them.³

Gasoline’s Hazard Classifications

Gasoline carries the signal word “Danger,” the highest severity level under the Globally Harmonized System.⁴ Section 2 of the SDS will show four or five pictograms and multiple classifications:

Flammable Liquid, Category 1. Gasoline has a flash point around −45 °F, well below the 73.4 °F cutoff for the most dangerous flammable liquid category. It can ignite at virtually any temperature encountered outdoors or in a workplace.
Carcinogenicity, Category 1A. Benzene in gasoline is a known human carcinogen, linked primarily to leukemia after prolonged exposure.
Germ Cell Mutagenicity, Category 1B. Benzene can damage reproductive cells.
Aspiration Hazard, Category 1. Swallowing even a small amount can send liquid into the lungs and cause severe or fatal chemical pneumonia.
Skin and Eye Irritation, Category 2. Direct contact irritates skin and eyes; repeated exposure causes dermatitis.

Section 3 of the SDS lists the hazardous ingredients by CAS number. The ingredient that drives most of the regulatory concern is benzene (CAS 71-43-2), typically present at 0.1% to 4.9% by weight in conventional gasoline.⁵ The other key aromatics are toluene, ethylbenzene, and xylene, collectively known as BTEX. Modern blends also usually contain ethanol as an oxygenate.

Exposure Limits

Here is something that catches people off guard: OSHA has no permissible exposure limit for gasoline vapor as a whole.⁶ Enforcement instead focuses on individual hazardous components, and benzene is the one that matters. The OSHA PEL for benzene is 1 ppm as an 8-hour time-weighted average, a very low threshold that reflects how dangerous chronic exposure is.⁷

The ACGIH publishes a Threshold Limit Value for total gasoline vapor at 300 ppm over an 8-hour TWA, with a short-term exposure limit of 500 ppm. ACGIH values are not legally enforceable the way OSHA PELs are, but many employers use them as the working benchmark for respiratory protection because they are updated more frequently.

Acute overexposure to gasoline vapor causes headaches, dizziness, nausea, and confusion. At high concentrations, especially in confined spaces, it can cause loss of consciousness and death. Chronic exposure creates the long-term risk of benzene-related blood cancers and bone marrow damage. Section 11 of the SDS lays out these effects in detail.

First Aid

Section 4 of the SDS tells you what to do when exposure happens. The response depends on the route.

Inhalation: move the person to fresh air immediately. If they are not breathing, trained personnel should provide artificial respiration. Get medical attention right away.
Skin contact: remove contaminated clothing and wash the affected area thoroughly with soap and water. Gasoline strips natural oils from skin, and prolonged contact causes chemical burns and dermatitis.
Eye contact: flush eyes with clean, low-pressure water for at least 15 minutes while holding the eyelids open, then seek medical attention.
Ingestion: do not induce vomiting. If the person vomits on their own, keep their head lower than their hips to reduce aspiration risk. Call poison control or emergency services immediately.⁸

The “do not induce vomiting” instruction is the single most important first aid fact on a gasoline SDS. The instinct when someone swallows something toxic is to get it out. With gasoline, the aspiration risk from vomiting is far more dangerous than the liquid sitting in the stomach.

Fire Response

Gasoline fires burn fast and spread faster. With a flash point around −45 °F and an autoignition temperature between roughly 495 °F and 853 °F, gasoline vapor can ignite from a spark, a hot surface, or static discharge, no open flame required.

Section 5 lists the approved extinguishing agents: aqueous film-forming foam, dry chemical, and carbon dioxide. A direct stream of water is not effective and can make the situation worse by spreading burning liquid. Water spray or fog is appropriate only for cooling nearby containers exposed to fire, which prevents pressure buildup and rupture. Firefighters need full bunker gear and self-contained breathing apparatus, because burning gasoline produces carbon monoxide and other toxic combustion byproducts.

Spill Response

Section 6 sets three priorities for any release: eliminate ignition sources, contain the spill, and prevent it from reaching drains or waterways.

For small spills, absorb the liquid with an inert, non-combustible material such as sand, earth, or vermiculite, then place the contaminated absorbent in a sealed container for proper disposal. Tools must be spark-proof, and metal containers or equipment in the area should be bonded and grounded to prevent static discharge. Larger spills take the same approach at scale: dike the area and approach from upwind.

Gasoline that enters storm drains or sewers creates an explosion hazard far from the original spill, because vapors travel along enclosed channels and can ignite at a distant source. Releases that reach waterways can also trigger state environmental reporting rules and Clean Water Act obligations.

Personal Protective Equipment

Section 8 describes the gear workers need. The specifics depend on the task and the level of exposure.

Gloves: nitrile or neoprene. Gasoline degrades latex and many other glove materials rapidly.
Eye protection: safety glasses or chemical splash goggles, depending on splash or spray risk.
Respiratory protection: when ventilation is adequate, no respirator may be needed. When airborne concentrations approach the ACGIH TLV or the benzene PEL of 1 ppm, a NIOSH-approved air-purifying respirator with organic vapor cartridges is the minimum. In confined spaces or where concentrations are unknown, a supplied-air respirator is required.⁷
Skin protection: long sleeves and chemical-resistant clothing when extended contact is expected, such as during tank cleaning or major spill response.

Providing the gear is not enough. Under the Hazard Communication Standard, workers must be trained on why the PPE is necessary, how to use it, and how to recognize when it needs replacement.¹

Storage and Handling

Safe gasoline storage comes down to three things: contain the vapors, prevent ignition, and stop static buildup. Section 7 covers handling precautions, and the specific regulatory requirements come from OSHA’s flammable liquids standard at 29 CFR 1910.106.

Bonding and grounding are required any time gasoline is transferred between containers. The nozzle and receiving container must be electrically connected to prevent static sparks, whether the transfer is filling a portable safety can or loading a tank truck.⁹ Indoor storage rooms must have mechanical or gravity exhaust ventilation providing at least six complete air changes per hour, with the intake no more than 12 inches above the floor where heavy gasoline vapors settle.

Containers must stay tightly sealed when not in active use. Even small amounts of escaped vapor can reach flammable concentrations in a poorly ventilated room. Gasoline should be kept away from oxidizers, heat sources, and any equipment that can produce sparks. For quantities under five gallons, the standard is an approved safety can with a self-closing lid and flame arrester.

Employer Duties and Penalties

Under the Hazard Communication Standard, employers must maintain an SDS for each hazardous chemical in the workplace and ensure employees can access them during their shift.¹ Hazard communication violations are consistently among the most-cited OSHA standards each year. Missing SDS records, untrained workers, and unlabeled containers are the usual triggers.

As of 2026, the maximum penalty for a serious OSHA violation is $16,550. For willful or repeated violations, the ceiling is $165,514 per violation.¹⁰ A single inspection can produce multiple citations, one for each missing SDS, each untrained worker, or each unlabeled container, so the total exposure adds up quickly. The penalties adjust annually for inflation, though the 2026 amounts are unchanged from the prior year.¹¹
