Print Compliant GHS Labels: GHS Rev 7 (HCS 2024) Standards

To print your own compliant GHS labels you must get three things right at once: the right content (GHS Revision 7 / HCS 2024 elements pulled from the current SDS), the right color (a black symbol on a white field inside a mandatory red diamond — never black-and-white), and the right durability (a synthetic substrate and pigment ink that survive the jobsite, benchmarked to BS 5609). OSHA does not name a printer or an ink, but 29 CFR 1910.1200(f) requires labels that are legible, complete, and not defaced — and a paper sticker from an office inkjet will not survive a steel-deck rainstorm. This guide covers exactly what to source, what to buy, and how to verify a label before it goes on a drum.

DIY labeling: when it is allowed (and when it is not)

Printing labels on-site is most useful for secondary/workplace containers — the spray bottle, jerrican, or transfer drum you fill from a labeled bulk container. OSHA gives you two options for these under 29 CFR 1910.1200(f)(6):

• 29 CFR 1910.1200(f)(6)(i): reproduce the full GHS label (same elements as the shipped container), or
• (f)(6)(ii) — show the product identifier plus words, pictures, or symbols that provide at least general information on the hazards.

There is no size-based "reduced label" tier and no immediate-use label at all when the container is for the immediate use of the employee who fills it ((f)(8)). What you may not do is relabel a shipped container you sell or distribute with a home-brew label — that is the manufacturer/importer/distributor's duty under (f)(1), and the small-container accommodations in 1910.1200(f)(12) apply only to those shipped containers, not to your in-house labels.

The "Sharpie method" — writing "Cleaner" or "Acid" on a bottle — fails both options. A common name alone communicates none of the hazard information either (f)(6) option requires.

Step 1 — Source content from the Rev 7 SDS

OSHA's HCS 2024 final rule aligns the Hazard Communication Standard primarily with GHS Revision 7. Despite the "Rev 7 / Rev 8" phrasing you will see online, OSHA did not adopt GHS Revision 8 wholesale — so your label-printing software and source data should sit on a Rev 7 footing. The number on the box matters less than this rule: the label content must match the classification on the current SDS.

Pull these six elements straight from Section 2 of the SDS (the GHS shipped-label elements under 1910.1200(f)(1)):

Your printing software must classify the HCS 2024 hazard classes correctly. Three physical-hazard classes were finalized by the rule:

Note that none of these new classes has a new pictogram — they all map to the existing eight OSHA symbols. If your software invents a tenth symbol or denies that "Chemicals Under Pressure" exists, it is out of date.

Fitting a multi-hazard label: rationalize the text, never the symbols

A frequent printing bind: a chemical with several hazards generates a wall of statements that won't fit the label. The rule for resolving it is asymmetric. Pictograms and hazard statements must all appear — you may never drop one to make room. Precautionary statements, on the other hand, can be rationalized: OSHA's Appendix C allows combination P-statements (one line covering several related precautions) and lets you omit statements that are clearly redundant or duplicative for the specific product. So when a label is too crowded, the compliant move is to combine and de-duplicate the precautionary statements — not to shrink a pictogram to illegibility or cut a hazard statement. (The "limit to six precautionary statements" figure you may have seen is EU CLP guidance, not OSHA — OSHA's test is simply that the required elements appear and stay legible.)

Step 2 — Get the color right (the red diamond is non-negotiable)

This is the single most common DIY failure. Per 29 CFR 1910.1200 Appendix C (C.2.3.1), every pictogram must be:

• a black hazard symbol,
• on a white background,
• inside a red frame that is a square set at a point (a diamond), and
• with the red frame sufficiently wide to be conspicuous.

A black-and-white diamond is not compliant. A red frame with no symbol inside it is prohibited — you may not ship blank red diamonds. If you own only a monochrome laser printer, the fix is to buy pre-printed stock with empty red diamonds and overprint the black symbols, or move to a color-capable printer (below).

Step 3 — Choose a substrate and ink that survive the jobsite

OSHA does not name an adhesive or ink brand, but it does require labels to be legible and not defaced or removed (1910.1200(f)). A paper label that turns to mush in the rain or whose ink rubs off violates that duty in practice. The accepted durability benchmark is BS 5609 — and it is mandatory for labels on chemicals shipped by sea (IMDG):

Practical pairings that pass:

• Pigment inkjet (or laser) on synthetic film — vinyl, polypropylene (BOPP), or polyester. Pigment ink resists water and UV far better than dye.
• Thermal-transfer printer with a resin ribbon on polyester — the industrial standard for drums, totes, and outdoor exposure.
• Avoid: standard paper labels and dye-based office inkjet output. They fail Section 3 quickly outdoors.

Worked example: labeling a 5-gallon diesel transfer can

A crew decants diesel from a bulk tank into a 5-gallon metal can that stays on the truck. The can is a secondary container used by more than the person who filled it, so (f)(6) applies (the (f)(8) immediate-use exception does not, because it is not for the filler's immediate use only).

1. Pull content from the diesel SDS, Section 2. Diesel is a flammable liquid, Category 3 (flash point ≥ 73.4°F and ≤ 140°F per App B.6.1) and carries health hazards (aspiration, carcinogenicity). Signal word: Danger.
2. Select pictograms: Flame (flammable) + Health Hazard (aspiration/carcinogen) — both as black-on-white inside red diamonds. (Show all applicable; never drop one to save space.)
3. Hazard statements: e.g., "Flammable liquid and vapor," "May be fatal if swallowed and enters airways," "Suspected of causing cancer." Verbatim from the SDS.
4. Choose option: Use (f)(6)(i) — the full label — for a high-hazard fuel rather than the abbreviated (f)(6)(ii) option.
5. Print durable: Pigment inkjet on polypropylene film, or thermal-transfer resin on polyester — a fuel can lives outdoors.
6. Verify against the checklist below before it goes on the can.

Pre-print compliance checklist

• Content sourced from the current (Rev 7) SDS, Section 2 — identifier matches exactly.
• All applicable pictograms shown (not just one); black symbol, white field, red diamond.
• One signal word ("Danger" or "Warning"); hazard statements verbatim.
• No black-and-white diamonds; no empty (symbol-less) red diamonds.
• Substrate + ink rated for the environment (synthetic film + pigment/resin, BS 5609 where applicable).
• For secondary containers: full label (f)(6)(i) or identifier + general hazard info (f)(6)(ii) — never a bare common name.
• Software classifies HCS 2024 classes correctly (Desensitized Explosives B.17, Aerosols B.3, Chemicals Under Pressure B.3.2) — no invented symbol.

Common myths and mistakes

• Myth: "≤100 mL means I can omit hazard statements." False under OSHA. That numeric cutoff is EU CLP, not 29 CFR 1910.1200. OSHA's small-container relief (1910.1200(f)(12)) applies only to the manufacturer's shipped container, has its own conditions, and never lets you drop required information on your own secondary labels. See Small Packages and Pull-Out Labels.
• Mistake: black-and-white pictograms. The red frame is mandatory; monochrome diamonds fail.
• Mistake: blank red diamonds. A red frame with no symbol is explicitly prohibited.
• Mistake: paper labels outdoors. They fade, smear, and peel — failing the "legible / not defaced" duty.
• Mistake: chasing "Rev 8." OSHA's HCS 2024 is primarily Rev 7; match the SDS, not the newest UN number.

What to do next

Build labels with the correct eight OSHA pictograms — red-framed and SDS-matched — using the GHS Label Generator, then size them to your container with the Container Size Matcher. For the underlying rules, start at the GHS Labels hub, read GHS Label Requirements, the difference between shipped vs. workplace labels, and why 8 OSHA pictograms — not 9. Construction sites adopt HazCom through 29 CFR 1926.59, which incorporates 1910.1200 by reference.
