Diesel fuel safety data sheet: what every employer must know

Last updated 2026-07-09

What is a diesel fuel safety data sheet and why does OSHA require it?

A diesel fuel safety data sheet tells you, in plain terms, what is in the product, what it does to your body and your workplace, and what to do when something goes wrong. OSHA requires it under the Hazard Communication Standard, 29 CFR 1910.1200, which adopted the United Nations Globally Harmonized System (GHS) format in 2012. ^[1]

Here is the rule in one sentence. If your employees could be exposed to diesel fuel during their work, you must have a current SDS on file, make it accessible during every shift, and train employees to use it.

That catches more businesses than people expect. Construction crews. Fleet maintenance shops. Farms with bulk fuel tanks. Warehouses running diesel forklifts. Anywhere diesel gets stored, pumped, or burned in quantity.

Before 2012, these were Material Safety Data Sheets (MSDSs) with no fixed format. The GHS switch locked the layout into exactly 16 sections, in a set order, across every chemical. ^[1] That matters for diesel because different refineries produce slightly different formulations, but the sections and their sequence never change, so a worker trained on one sheet can read any other.

Diesel is classified as a combustible liquid (flash point typically 52°C to 96°C depending on grade) and a skin irritant, and its exhaust is a confirmed human carcinogen under IARC Group 1. ^[2] Those classifications drive what the SDS says about hazards, limits, and controls.

For how hazard communication works as a full system, with labels, pictograms, and training, that article covers the whole standard.

What are the 16 sections of a diesel fuel SDS?

Every diesel fuel SDS follows the same order, set by 29 CFR 1910.1200 Appendix D. ^[1] Sections 1 through 11 and 16 are enforceable in the US; sections 12 through 15 are non-mandatory but almost always filled in. Here is what each one holds and where to look first.

Section	Title	What to look at
1	Identification	Product name, supplier contact, emergency phone number
2	Hazard(s) identification	GHS signal word (Warning or Danger), pictograms, hazard statements
3	Composition/ingredients	CAS numbers for key components: distillates, naphthalenes, benzene traces
4	First-aid measures	Skin, eye, inhalation, ingestion instructions; physician notes
5	Fire-fighting measures	Extinguisher types, flashpoint, auto-ignition temp, special hazards
6	Accidental release measures	Spill cleanup steps, containment, environmental reporting
7	Handling and storage	Storage temperature, incompatibles, bonding/grounding for static
8	Exposure controls/PPE	OSHA PELs, NIOSH RELs, ACGIH TLVs, required PPE
9	Physical and chemical properties	Flashpoint, boiling range, vapor density, solubility
10	Stability and reactivity	Conditions to avoid, incompatible materials
11	Toxicological information	Routes of exposure, LD50 data, carcinogenicity, IARC classification
12	Ecological information	Aquatic toxicity, bioaccumulation (informational in the US)
13	Disposal considerations	Waste codes, regulatory disposal requirements
14	Transport information	DOT hazard class (Class 3 flammable liquid), UN number (UN 1202)
15	Regulatory information	SARA 313, RCRA, state right-to-know lists
16	Other information	Revision date, preparer info, key abbreviations

Section 2 and Section 8 are where most employers should spend their time. Section 2 tells you how bad the hazard is. Section 8 tells you the enforceable limits and the controls you owe your workers.

Sections 12 through 15 are labeled non-mandatory in the US under Appendix D, but most suppliers complete them anyway, and you may need them for EPA or DOT compliance. ^[1]

One thing trips people up: the revision date in Section 16. OSHA sets no expiration date, but the standard requires the sheet to reflect current information. A 2009 sheet that never went through the GHS conversion is not compliant. Pull a current one straight from your fuel supplier's website.

What are the exposure limits for diesel fuel listed on the SDS?

Section 8 lists occupational exposure limits from three bodies, and only one of them is law. OSHA's Permissible Exposure Limit (PEL) for petroleum distillate vapors, which covers diesel fuel, is 100 ppm as an 8-hour time-weighted average under 29 CFR 1910.1000 Table Z-1. ^[3] That is the enforceable number. The other two are advisory.

OSHA's Z-1 limits date to 1971 and are widely acknowledged to lag current science. NIOSH's Recommended Exposure Limit (REL) for diesel exhaust, measured as elemental carbon, is 0.1 mg/m3 as a 10-hour TWA. ^[4] NIOSH RELs are not enforceable by OSHA, but they reflect more recent toxicology and show up on most modern diesel SDSs.

ACGIH sets a Threshold Limit Value (TLV) for diesel fuel vapors at 100 mg/m3 as a TWA. ^[5] Advisory, again, not law.

Here is the part that should change how you think about the whole document. Diesel engine exhaust is a Group 1 carcinogen, carcinogenic to humans, per IARC. ^[2] The SDS reflects this in Section 11. Workers who do engine maintenance in enclosed spaces, fuel vehicles indoors, or monitor idling engines for long stretches face the highest risk, and the PEL alone does not address it.

For a given task, Section 8 spells out ventilation, respirator type, and skin protection. Treat those as instructions, not boilerplate.

What health hazards does diesel fuel pose according to its SDS?

Section 2 and Section 11 tell the health story together. Skin contact defats and irritates with repeated exposure. Eye contact irritates. Vapor inhalation above the exposure limit brings headache, dizziness, and nausea. Ingestion is the real emergency, because diesel can be aspirated into the lungs.

That covers the acute side. The chronic side is worse.

Diesel fuel contains polycyclic aromatic hydrocarbons (PAHs) and trace benzene, both tied to higher cancer risk over long exposures. IARC classifies diesel engine exhaust as Group 1, carcinogenic to humans, a classification set in 2012 on evidence from miners and truckers. ^[2] IARC's own conclusion was that there is "sufficient evidence in humans for the carcinogenicity of diesel engine exhaust" and that it causes lung cancer. Most diesel SDSs reflect this in Section 11, some by listing the IARC exhaust classification directly, others by calling the fuel a possible carcinogen under OSHA's HazCom definitions.

Benzene gets its own line. Diesel fuel typically holds benzene below 0.1% by weight, which keeps most formulations under the threshold that triggers the separate benzene standard, 29 CFR 1910.1028. ^[6] Check Section 3 of your product's actual sheet, because formulations vary by supplier and region.

On flammability, No. 2 diesel has a flashpoint near 52°C (126°F) by ASTM D93 testing, which is why it does not light off like gasoline at room temperature. ^[7] But diesel vapors pool in low spots and confined spaces, so the fire hazard is real during tank fueling and inside enclosed vehicles.

Most diesel formulations carry the GHS signal word "Warning," not "Danger," because the acute toxicity is moderate. Do not let the milder word talk you out of respecting the chronic hazard.

What PPE does a diesel fuel SDS require?

Section 8 lists the required personal protective equipment, and the specifics scale with the task and the exposure. Chemical-resistant gloves come first. Nitrile at 8 mil or thicker is the usual call for prolonged or repeated contact; thin disposable nitrile does not hold up during extended fueling. A chemical-resistant apron handles splash risk on bulk transfers.

Eye protection: safety glasses with side shields for routine work, and chemical splash goggles anytime a splash is possible, like connecting or breaking hose fittings on bulk tanks.

Respiratory protection depends on where you are. Outdoor fueling in open air usually needs none if exposures sit below the PEL. Enclosed-space work with a running diesel engine, or any task where vapor monitoring shows concentrations near the 100 ppm OSHA PEL, calls for an air-purifying respirator with organic vapor cartridges. ^[3] Run a respirator program and it has to meet 29 CFR 1910.134.

Foot protection: chemical-resistant footwear or boot covers where diesel is likely to hit the floor.

The SDS rarely knows your exact conditions, so the honest move is an exposure assessment for your actual tasks, especially fueling in enclosed bays or working near idling engines. OSHA's general industry standard at 29 CFR 1910.132 requires a written certification of your PPE hazard assessment. ^[8]

If your shop handles several hazardous chemicals and you want the PPE requirements written into a program fast, the SafetyFolio safety program generator can assemble a compliant PPE hazard assessment in about 15 minutes instead of a blank-page build.

What should you do if a diesel fuel spill or exposure happens?

Section 4 covers first aid, Section 6 covers spills, and you want to know both before the moment arrives.

Skin exposure: strip contaminated clothing right away and wash the area with soap and water for at least 15 minutes. There is no antidote for routine skin contact, and no SDS pretends otherwise. If irritation lasts, get medical attention. The hazard is repeated exposure without washing, not a single brief splash.

Eye exposure: flush with lots of water for at least 15 minutes, eyelids held open, then get medical attention. Most SDSs call eye irritation reversible, but flushing time is what makes it reversible.

Inhalation: move the person to fresh air. If breathing is labored or they lose consciousness, call 911 and give oxygen if you are trained. Watch for dizziness, headache, and disorientation.

Ingestion: do NOT induce vomiting. Diesel aspirated into the lungs during vomiting causes chemical pneumonitis, which is a medical emergency. Call Poison Control (1-800-222-1222) and get the person to an emergency room.

Spills: Section 6 on most diesel sheets says stop the source if it is safe, soak up the liquid with non-combustible material (sand, vermiculite, commercial absorbent), keep it out of storm drains and surface water, and dispose of the waste under local rules. Diesel becomes a regulated hazardous waste when it mixes with other contaminants.

Any spill that reaches surface water or a storm drain triggers CERCLA Section 103 and Clean Water Act reporting to the National Response Center (1-800-424-8802) once it hits the reportable quantity for petroleum products. ^[9] That requirement lives in Section 6 and Section 15 of the SDS.

An exposure that becomes a work-related illness or injury may land on your OSHA 300 log. The incident report guide walks through what counts as recordable.

How do you get a diesel fuel SDS and keep it compliant?

Your fuel supplier has to give you one. Under 29 CFR 1910.1200(g), chemical manufacturers and importers must provide a current SDS with each shipment of a hazardous chemical. ^[1] If it does not show up, ask by name. Most large distributors (ExxonMobil, Chevron, BP, and regional suppliers) post SDSs on their websites, searchable by product.

For No. 2 diesel, the most common grade, search the supplier's product safety page for "Diesel Fuel No. 2" or "ULSD" (ultra-low sulfur diesel). Other grades have their own sheets with different hazard profiles: No. 1 diesel, off-road red-dyed diesel, biodiesel blends. Never use a No. 2 sheet for a B20 blend. The hazard data is not the same.

Storage of the file itself is simpler than people fear. OSHA mandates no particular system, only that SDSs stay "readily accessible" to employees during each shift when they are in their work area. ^[1] Paper binders, shared drives, and third-party SDS software all pass, as long as a worker can actually reach the sheet without a password maze or a locked cabinet only a manager can open.

Electronic systems are fine when nothing blocks access: no login a worker lacks, no software that goes dark with no backup. If your site has flaky internet, keep paper.

On updates, a supplier who reformulates the product or learns of new hazard data must send a revised SDS within three months. ^[1] Keep the newest version active. You do not need old versions for compliance, though holding them a few years helps if a former employee later claims illness from past exposure.

How do you train employees to use a diesel fuel SDS?

OSHA's Hazard Communication Standard requires training at initial assignment and whenever a new hazard enters the workplace. ^[1] Training has to cover how to read and use an SDS, not merely that one exists somewhere in a binder.

For diesel, cover at least this:

• Where the SDS is and how to reach it during a shift
• What the key Section 2 hazard statements mean on the job
• What the Section 8 exposure limits mean for actual tasks
• The Section 4 first aid steps and where emergency supplies live
• The Section 6 spill response steps
• The Section 8 PPE, plus how to inspect and wear it
• The Section 5 flammability facts, including flashpoint and what it means near ignition sources

Training does not need a formal course. A toolbox talk with a sign-in sheet, a walkthrough at the fuel station going section by section, or a short online module all satisfy the requirement, as long as you can show the content was covered and understood. Keep the records. Inspectors ask for them.

For employees who run diesel-fueled powered industrial trucks, SDS training ties straight into their forklift certification under 29 CFR 1910.178. Operators should know the fuel's hazards before they fuel or service the machine.

Want more structure? OSHA training at the 10-hour or 30-hour level runs hazard communication as a core module, and an OSHA 30 course goes deeper on chemical hazard standards for supervisors who need the regulatory framework.

What are the storage and handling requirements shown on a diesel fuel SDS?

Section 7 handles storage and handling, and for most small businesses the practical requirements are short. Keep diesel away from heat and open flame. Aboveground tanks in direct sun warm enough to raise vapor pressure and speed evaporation, though the fuel stays well below its flashpoint in most climates.

Static electricity is the one people underrate. Diesel flowing through pipes and hoses during a bulk transfer builds static charge. Bond the fuel nozzle to the receiving tank and ground both containers before transfer. It is standard practice and most diesel SDSs reference it. NFPA 77 covers static grounding for flammable and combustible liquids. ^[10]

Section 10 lists strong oxidizers as incompatible with diesel. In a shop or on a farm, that means keeping diesel away from chlorine-based cleaners, pool chemicals, and compressed oxygen cylinders.

Aboveground storage tanks fall under OSHA's flammable liquids standard, 29 CFR 1910.106. ^[11] Diesel, with a flash point above 38°C (100°F), is a Class II combustible liquid under NFPA 30, not a flammable liquid, and that classification changes tank construction and separation distance rules. Plenty of small businesses get this backward. Check NFPA 30 and your local fire code, not only the federal OSHA standard.

Secondary containment is required for bulk diesel tanks at most facilities under EPA's Spill Prevention, Control, and Countermeasure (SPCC) rule once you store more than 1,320 gallons aboveground in aggregate. ^[12] That threshold catches a lot of farms, fleets, and construction companies with big tanks on-site.

What regulatory requirements show up in Section 15 of the diesel SDS?

Section 15 is where federal and state regulatory status appears, and for diesel a few entries matter. SARA Title III Section 313: diesel fuel is captured through several component chemicals (naphthalene, benzene, 1,2,4-trimethylbenzene). Facilities that manufacture, process, or use these above threshold quantities must report yearly to EPA's Toxics Release Inventory. ^[13] Most businesses that just burn diesel as fuel stay below the thresholds, but check if you run a depot or a blending operation.

RCRA comes next. Spent diesel and diesel-soaked materials (absorbents, rags, contaminated soil) can be hazardous waste under the Resource Conservation and Recovery Act if they fail the TCLP test or meet a listed-waste definition. The SDS flags this and points you to the applicable rules.

State right-to-know laws add layers. California's Proposition 65 lists diesel engine exhaust as a known carcinogen and reproductive toxicant, so diesel SDSs for California sites usually carry Prop 65 warning language in Section 15. ^[14] New Jersey, Pennsylvania, and Massachusetts run their own right-to-know lists that may demand extra disclosures.

Section 14 carries the transport line. No. 2 diesel ships as a Class 3 flammable liquid, UN 1202, Packing Group III. Move diesel above DOT thresholds and you need placards, and the shipping papers have to carry the UN number and hazard class. That matters for any business hauling diesel or carrying it in portable containers between sites.

If you operate in more than one state, remember that chemical safety and programs like lockout tagout can vary by state OSHA plan. Check whether your state runs its own plan with requirements above the federal baseline.

What is the difference between a diesel SDS and the old MSDS format?

Before 2012, Material Safety Data Sheets used a loose, variable format. OSHA's HazCom 2012 rule, effective June 1, 2015 for most employers, replaced them with the standardized 16-section SDS aligned to GHS. ^[1] The differences are practical, not cosmetic.

Old MSDSs might run 8 sections or 16, in any order, with inconsistent terms. The new SDS has exactly 16 sections, fixed order, standardized hazard-category language. Learn to read one GHS SDS and you can read them all.

Pictograms are new. GHS added nine standardized pictograms (flame, skull and crossbones, exclamation mark, and the rest) that appear on labels and get referenced in the SDS. Diesel usually carries the flame pictogram plus the exclamation mark for irritation.

Signal words are standardized too. "Danger" flags the more severe hazard categories; "Warning" flags the less severe. Most diesel formulations land on "Warning."

Still have MSDSs for diesel or any other chemical? They are not compliant. Swap them for GHS-format SDSs from your current supplier. OSHA's full-implementation deadline for distributors and employers was June 1, 2016. ^[1]

One thing never changed: your obligation to keep the sheets, make them accessible, and train employees. That duty predates GHS and carries straight through the current standard.

How does the diesel fuel SDS connect to your written hazard communication program?

An SDS in a binder is not a compliance program. Under 29 CFR 1910.1200(e), any employer with hazardous chemicals must keep a written hazard communication program describing how they manage labels, SDSs, and training. ^[1] The SDS is one part of that program, never a substitute for it.

Your written HazCom program should spell out:

• How you obtain and maintain SDSs for every hazardous chemical, diesel included
• Where SDSs live and how employees reach them
• How you handle new chemicals before they arrive on-site
• Your container labeling system
• How and when training happens and gets documented

A multi-chemical workplace makes this real. A maintenance shop might stock diesel, engine oil, battery acid, solvents, and brake cleaner. Keeping all of it organized takes either a disciplined manual system or software that manages your chemical inventory and SDS library together.

That is where SafetyFolio's safety program generator earns its keep. You can build a written HazCom program covering diesel and your other chemicals in about 15 minutes, with the required policy elements already structured to meet 29 CFR 1910.1200(e), and skip paying a consultant to draft it from a blank page.

For every element a written HazCom program must include, the hazard communication article on this site walks through the full list.

Frequently asked questions

Is a diesel fuel SDS legally required even for a small business?

Yes. OSHA's Hazard Communication Standard (29 CFR 1910.1200) covers all employers with hazardous chemicals, with no small-business exemption. If your employees handle, store, or are exposed to diesel fuel, you must keep a current SDS on file and accessible during each shift. The standard applies to both general industry and construction.

Where can I get a free diesel fuel SDS?

Your fuel supplier is required to provide one with each shipment. Major suppliers (ExxonMobil, Chevron, BP, Shell) post current SDSs on their product safety pages. Search the supplier's site for the specific grade (for example, 'Diesel Fuel No. 2 ULSD'). Third-party SDS databases and manufacturer portals also work, but always confirm the revision date and that the formulation matches your product.

How often does a diesel fuel SDS need to be updated?

OSHA requires manufacturers to revise an SDS within three months of learning significant new hazard information (29 CFR 1910.1200(g)(5)). There is no fixed expiration date, but a sheet that predates the 2015 GHS implementation is not compliant. Check the revision date in Section 16, and request a new SDS immediately if your supplier reformulates the product.

What is the OSHA PEL for diesel fuel vapor?

OSHA's Permissible Exposure Limit for petroleum distillate vapors, which covers diesel fuel, is 100 ppm as an 8-hour time-weighted average under 29 CFR 1910.1000 Table Z-1. NIOSH recommends a lower REL of 0.1 mg/m3 for diesel exhaust measured as elemental carbon. The NIOSH limit is not enforceable but reflects more current toxicology and appears on most modern diesel SDSs in Section 8.

Does diesel fuel have a flashpoint and what does it mean for safety?

Yes. No. 2 diesel fuel has a flashpoint near 52°C (126°F) by the ASTM D93 closed cup method. Flashpoint is the lowest temperature at which the liquid gives off enough vapor to ignite. Because diesel's flashpoint sits well above room temperature, it is less immediately flammable than gasoline, but diesel vapors in enclosed or low-lying spaces still create a real fire hazard, especially during bulk transfers.

Is diesel fuel a carcinogen according to the SDS?

Diesel engine exhaust is a Group 1 carcinogen (carcinogenic to humans) per IARC, based on evidence in heavily exposed workers like miners and truck drivers. Most diesel SDSs reflect this in Section 11, either listing IARC Group 1 for exhaust or classifying the fuel itself as a possible carcinogen. The fuel also contains trace PAHs and benzene, both linked to cancer at high cumulative exposures.

What type of gloves does a diesel fuel SDS recommend?

Section 8 of most diesel SDSs specifies chemical-resistant gloves, usually nitrile at 8 mil or thicker for prolonged contact. Thin single-use nitrile gives short-term splash protection but not extended dermal protection. Leather and cotton gloves absorb diesel and should not be used. For bulk transfers or maintenance with extended contact, heavier nitrile or neoprene gloves are the right choice.

What happens if diesel fuel is ingested?

Do NOT induce vomiting. Diesel aspirated into the lungs during vomiting causes chemical pneumonitis, a severe medical emergency. Section 4 of the SDS directs you to call Poison Control (1-800-222-1222) immediately and transport the person to an emergency room. Keep the SDS with the person so medical staff can see the composition listed in Section 3.

Does a diesel fuel SDS need to be accessible to employees at all times?

Yes. 29 CFR 1910.1200(g)(8) requires SDSs to be 'readily accessible' to employees during each work shift in their work area. Electronic systems are acceptable as long as no access barriers exist, such as logins workers do not have or systems without reliable backup. For remote or field operations with poor internet, a paper backup is the practical solution.

What is the difference between diesel No. 1 and No. 2 on the SDS?

No. 1 diesel (winter diesel) and No. 2 diesel have slightly different physical properties: No. 1 has a lower pour point and a lower flashpoint (about 38°C versus 52°C for No. 2). Their health hazard profiles are similar, but the flashpoint difference affects storage classification under NFPA 30. Always use the SDS for the specific grade you stock, not a generic diesel sheet.

Are biodiesel blends covered by the same SDS as regular diesel?

No. Biodiesel blends (B5, B20, B100) have separate SDSs because the composition and some hazard properties differ from petroleum diesel. B100 (pure biodiesel) is a combustible liquid with a higher flashpoint than petroleum diesel, which affects storage and fire ratings. Request the SDS for your specific blend and do not substitute a petroleum diesel sheet.

What should I do if a diesel spill reaches a storm drain?

Report it. CERCLA Section 103 and the Clean Water Act require notification to the National Response Center (1-800-424-8802) if a reportable quantity of a hazardous substance reaches navigable waters. For petroleum products, any sheen on water is enough to trigger reporting in most states. Section 6 of the diesel SDS references these requirements. Do not wait to see if it disperses.

Do forklift operators need diesel SDS training?

Yes. Any employee who could be exposed to diesel during fueling or maintenance of powered industrial trucks must get HazCom training that includes how to read the diesel SDS. This is separate from but complementary to forklift operator training under 29 CFR 1910.178. Operators who fuel their own equipment need both the operator safety training and the chemical hazard training.

What is Section 14 of a diesel SDS used for?

Section 14 covers transport information. For No. 2 diesel, it gives the DOT hazard class (Class 3 flammable liquid), UN number (UN 1202), and packing group (III). This information is required on shipping papers and for placarding transport vehicles carrying diesel above DOT thresholds. If you ship or move diesel between sites, your drivers and shipping personnel need to understand this section.
