How to Generate GHS Labels for Secondary Containers Without Printing Errors or Gaps

By

Generate GHS secondary container labels from the current Safety Data Sheet (SDS), print them on material suited to the actual exposure, verify the product identifier before application, and record the SDS revision used. This workflow prevents the two failures that matter most on the floor: a label that carries the wrong hazard information and a correct label that becomes unreadable.

A reliable process also separates secondary container labeling requirements from the different rules for stationary process containers and piping. Federal OSHA listed Hazard Communication, 29 CFR 1910.1200, as its second most frequently cited standard for fiscal year 2025. OSHA’s inspection data show 2,890 federal citations under the standard across all industries in that period.

Quick answer

Use one controlled SDS library as the source for every label. For demanding areas, a thermal transfer printer, compatible resin ribbon, synthetic stock, and tested adhesive are a sound starting point, but OSHA does not mandate a printer technology. Match the product identifier to the container, replace damaged labels rather than repairing them, and make label checks part of each shift’s existing walkthrough.

What printer and label materials survive chemical exposure?

Start with thermal transfer printing on polypropylene or polyester stock when labels face solvents, oil, abrasion, sunlight, or washdown. Pair the stock with a compatible resin ribbon and an adhesive rated for the surface and application temperature. These are practical material choices supported by vendor testing, not requirements stated in 29 CFR 1910.1200.

Zebra explains that ordinary direct thermal media can darken after excess heat or light exposure. Vendor tests are product-specific. Brady reports solvent and abrasion results for its B-488 polyester stock with an R4300 ribbon, while 3M reports chemical-resistance testing for its 92904 resin ribbon on specified synthetic media. Those results do not apply to every material combination.

Print method and stock

Best practical use

Likely failure to test

Thermal transfer with polypropylene and resin ribbon

General industrial containers with moisture, oils, or routine wiping

Adhesive lift or print damage from the site’s actual chemical

Thermal transfer with polyester and resin ribbon

Drums and containers exposed to more abrasion, heat, or solvents

Stock, ribbon, or adhesive incompatibility

Direct thermal stock

Short-life indoor identification in controlled conditions

Darkening or fading from heat, light, or abrasion

Laser or inkjet synthetic stock

Low-volume indoor use when the stock is approved for the printer

Smearing, toner loss, edge lift, or chemical attack

Run a site test before buying a full case. Apply the label as directed, then expose a sample to the area’s normal wipes, splashes, and washdowns. Keep small and large formats available so information remains legible without crowding.

How do we generate labels consistently across many areas?

Generate each label from one current SDS record, not a hand-built spreadsheet. OSHA’s workplace labeling rule at 29 CFR 1910.1200(f)(6) allows either the applicable shipped-label elements or a product identifier plus words, pictures, symbols, or a combination that communicates the hazards when employees can immediately access the supporting information.

  1. Inventory by area. Identify every workplace container on production lines and in chemical rooms.
  2. Match the current SDS. Confirm that the product identifier on the SDS matches the chemical actually in the container.
  3. Generate from SDS data. Use SDS Section 2 rather than retyping hazard information. See the six elements a compliant shipped label must carry before choosing a full GHS-style workplace label.
  4. Batch print by area. Keep unlike chemicals in separate print batches to reduce mix-ups.
  5. Verify before applying. Have the applicator or a second employee compare the product identifier on the new label with the container and SDS.
  6. Log the issue. Record the chemical, area, print date, and SDS revision date so the same approved version can be reproduced.

Hand-typed templates drift when an SDS changes but the local file does not. Generating from the controlled SDS record removes that duplicate source of truth.

How do we label chemicals with no manufacturer SDS?

Do not guess at a GHS classification. For a purchased product, request the SDS from the supplier and restrict use if the chemical cannot be identified safely. For an in-house blend or process intermediate, first determine whether your business has become a chemical manufacturer under the standard and must classify the mixture and prepare the required hazard communication information.

OSHA’s current enforcement directive states that a company that repackages, blends, mixes, or otherwise changes a chemical’s composition is considered a chemical manufacturer. Copying the most severe statement from every component is not a reliable substitute for the applicable mixture-classification method. If the composition or classification is uncertain, involve a qualified safety professional or the supplier.

Once hazards are determined, apply the marking allowed by 1910.1200(f)(6) and document the basis. This matters for process intermediates and labeling diluted cleaning chemicals. Prevent use of an unidentified legacy drum until it is characterized or properly disposed.

What should we do about faded or peeling drum labels?

Replace them. Do not trace over faded text or patch one missing element. Paragraph 1910.1200(f)(10) requires labels and other warnings to be legible, in English, and prominently displayed, though employers may add other languages. A useful floor rule is simple: An illegible label is the same violation as no label.

  1. Confirm the chemical and current SDS before removing anything.
  2. Clean and dry the surface according to the label manufacturer’s directions.
  3. Remove or fully cover the failed label so workers do not see conflicting information.
  4. Apply a newly generated label and record the replacement.

If the same drum fails repeatedly, check for chemical splash, sunlight, heat, washdown pressure, or surface contamination. Test a different stock, matched ribbon, overlaminate, or protected placard holder.

Do we need to label pipes and process tanks too?

Pipes are not containers under OSHA’s Hazard Communication Standard, so the container-labeling provisions in 1910.1200(f) do not apply to the piping itself. A stationary process tank is different. Under 1910.1200(f)(7), an employer may use signs, placards, process sheets, batch tickets, operating procedures, or similar written materials instead of a label on each stationary process container.

  • Secondary or transfer container: Apply the workplace-container rule unless a specific exception applies. Review which containers actually need labeling.
  • Stationary process tank: A linked placard or process document can be used if it identifies the container and conveys the required hazard information.
  • Pipe: HazCom container labeling does not apply. ASME A13.1-2023 is a consensus standard for identifying fluids in aboveground piping, not a blanket OSHA HazCom mandate.

OSHA’s November 10, 1988 interpretation to Katherine S. Davis confirms the piping exclusion. Other standards, state-plan rules, fire codes, or contracts may still call for pipe identification. A marked tank also does not excuse an unlabeled transfer bottle or pail.

How do we keep labels current across multiple shifts?

Attach label checks to a walkthrough that already happens, then give every shift the same way to replace a label and reach the current SDS. OSHA requires effective HazCom information and training at initial assignment and whenever a new chemical hazard employees have not previously been trained about enters the work area under 1910.1200(h)(1).

Assign an owner for each area on each shift. During the walk, ask whether any container is unlabeled, unreadable, or holding something different from its label. Keep approved label supplies nearby, and train employees to use the system and find the supporting SDS.

29 CFR 1910.1200(f)(11) requires covered workplace labels to be revised within six months after the employer becomes newly aware of significant hazard information. Build that trigger into SDS revision review rather than waiting for the monthly floor audit. QR and mobile access can support immediate SDS retrieval, but access must remain available to employees in their work areas throughout every shift. For facilities managing many areas, see SDS management for manufacturing facilities.

How Helios Comply helps

Helios Comply connects GHS secondary container label generation to the cloud SDS library employees access by QR code. An operations manager can generate a replacement from the current record instead of rebuilding hazard text. Multi-location management and offline access support the same process across areas and shifts.

Software does not classify an unknown mixture, select materials for every exposure, or replace the employer’s written program and training. It can remove duplicate files and make the approved SDS easier to reach. Helios also provides pre-populated SDS books.

Start a free trial to organize your SDS library and generate secondary container labels from it. For hands-on setup help, call (855) 920-5202.

Frequently asked questions

Can I handwrite a secondary container label?

Yes, if it meets 1910.1200(f)(6), remains legible, and connects employees to immediately available hazard information. A product name alone may not communicate enough.

Does a portable container used within one shift need a label?

OSHA provides an exception for a transfer made for one employee’s immediate use. The chemical must remain under that employee’s control and be used only by that employee within the shift. Otherwise, label it.

Do pipes need GHS labels?

No. HazCom excludes pipes and piping systems from “container.” ASME A13.1 is a consensus standard for pipe identification, but other standards, codes, state requirements, or contracts may apply.

Can a QR code replace the label on a process tank?

Not by itself. The alternative must identify the container and convey the required information under 1910.1200(f)(7). A QR code can support access when employees can retrieve the information immediately on every shift.
