How to Label Secondary Chemical Containers to OSHA and GHS Rules

This guide covers containers that stay inside one workplace in the United States or the European Union. It does not cover labels on containers shipped to another company, transport marking, or national rules in other countries.

What must a workplace label show under OSHA 29 CFR 1910.1200(f)(6)?

A workplace label under OSHA 29 CFR 1910.1200(f)(6) must show either the full shipped-label content or, at minimum, the product identifier plus words, pictures or symbols that give general information about the chemical's hazards (OSHA, 2026). The first option copies five elements from the supplier label: product identifier, signal word, hazard statements, pictograms and precautionary statements (OSHA, 2026). The second option complies only when the rest of the hazard communication program, such as training and the SDS file, gives employees the specific hazard information. OSHA's inspection directive for the Hazard Communication Standard (HCS), effective 19 May 2026, says pictograms are not required on in-house labels and that symbols must not contradict the Globally Harmonized System (GHS) pictograms (OSHA, 2026). The same directive says an employer using the shorter label bears the burden of showing that employees understand the hazards as well as they would from a full label (OSHA, 2026). Either way, the label must be legible, in English and prominently displayed (OSHA, 2026).

What do you need before you label a secondary container?

Before you label a secondary chemical container, you need the current SDS for the exact product, a compatible container, durable label stock and the protective equipment the SDS names. Take the SDS from your hazardous chemical list, which OSHA requires to use a product identifier referenced on the SDS (OSHA, 2026). Read SDS section 7, which covers precautions for safe handling and conditions for safe storage, including any incompatibilities, before you pick the receiving container (OSHA, 2026). Wear the protective equipment listed in SDS section 8 during the transfer. In industrial plants, OSHA 29 CFR 1910.106(e)(6)(ii) bars dispensing Category 1 or 2 flammable liquids, or Category 3 flammable liquids with a flashpoint below 37.8 °C (100 °F), into containers unless the nozzle and container are electrically interconnected (OSHA, 2016). In the EU, this preparation sits inside the employer's chemical risk assessment under Directive 98/24/EC, which requires the employer to determine whether hazardous chemical agents are present and assess the risk (Directive 98/24/EC, Article 4, 1998). Test a sample label against the product before using that stock site-wide.

Step by step: labeling a secondary chemical container

Labeling a secondary chemical container follows five steps for spray bottles, safety cans and drums alike.

1. Identify the product. Copy the product identifier exactly as it appears in SDS section 1, which OSHA Appendix D defines as the product identifier used on the label (OSHA, 2026).

2. Pull SDS section 2. Take the signal word, hazard statements, pictograms and precautionary statements from section 2 (OSHA, 2026).

3. Choose the label format. Pick the full five-element label or the shorter identifier-plus-hazards label. In the EU, add the CLP hazard pictograms for any physical or health hazard (Directive 92/58/EEC Annex III, 2014). On a US in-house label, a pictogram may carry a black border instead of a red one (OSHA, 2013).

4. Fill and apply. Transfer under the SDS section 7 and 8 controls, electrically interconnecting nozzle and container for Category 1 or 2 flammable liquids, or Category 3 flammable liquids below 37.8 °C (100 °F), as 29 CFR 1910.106(e)(6)(ii) requires in industrial plants (OSHA, 2016). Fix the label on the container body; the EU text asks for signs on the visible side or sides, in unpliable, self-adhesive or painted form (Directive 92/58/EEC Annex III, 2014).

5. Audit it. Check the finished label against the 10 checks in the table below before the container leaves your hands.

How do you check the finished secondary container label?

A finished secondary container label passes when a worker who has never seen the container can name the product, find its SDS and state its main hazards from the label and the labeling system they were trained on. The table below decides pass or fail for each check under OSHA 29 CFR 1910.1200 and the EU workplace directives.

The key row in the secondary container label check is the product identifier. OSHA's inspection procedure tells inspectors to check that the product identifier on a container can be cross-referenced with the SDS and with the inventory list of hazardous chemicals (OSHA, 2026). When the name on a secondary container does not match SDS section 1, the hazard words next to it cannot be traced, so fix that row first. The immediate-use row is the next most consequential: a container shared with anyone else, or left for a later shift, fails and needs a workplace label.

When does a portable container not need a label?

A portable container does not need an OSHA label only when the chemical was transferred from a labeled container and the container is intended only for the immediate use of the employee who performed the transfer (OSHA, 2026). In a 1990 interpretation letter, OSHA said no to a plant that wanted to leave small process containers unlabeled because every shift knew their contents, and stated that containers used by employees other than the one performing the transfer, "including employees on other shifts", must be labeled (OSHA, 1990). The letter cites the exemption under its 1990 paragraph number; the same wording now sits in paragraph (f)(8). A spray bottle left on a cart for the next crew therefore needs a label. Quality control samples follow the same logic: OSHA's 2026 inspection directive says they must be labeled unless the person taking the sample also performs the analysis (OSHA, 2026). EU rules use a different test. Directive 92/58/EEC Annex III exempts containers used at work for brief periods and containers whose contents change frequently, but only if alternative adequate measures, in particular information or training, guarantee the same level of protection (Directive 92/58/EEC Annex III, 2014).

Common mistakes in secondary container labeling

Secondary container labeling mistakes addressed in OSHA guidance and letters fall into six patterns.

• Using a nickname instead of the SDS product identifier, so the container cannot be cross-referenced with the SDS and the chemical list (OSHA, 2026).

• Treating bottles on shelves or in cabinets as stationary process containers covered by one sign; OSHA said in 1989 that each one must carry the required information (OSHA, 1989).

• Filling an NFPA 704 diamond with GHS category numbers from SDS section 2. NFPA ratings run 0 to 4 with 4 the most hazardous, OSHA categories run 1 to 4 with 1 the most severe, and OSHA says the category numbers are not to be used to fill in the diamond (OSHA, 2013).

• Relying on an NFPA 704 rating alone for a chemical with a chronic health hazard; NFPA 704 covers acute health hazards only (OSHA, 2013).

• Pointing to the SDS binder instead of labeling. OSHA's directive says other information immediately available to employees does not include safety data sheets used in lieu of labels (OSHA, 2026).

• Covering or painting over the supplier label on an incoming container without immediately re-marking it, which the standard prohibits (OSHA, 2026).

How often should you audit workplace chemical labels?

Audit workplace chemical labels whenever an SDS revision changes the hazard information, and on a fixed schedule written into your hazard communication program, because 29 CFR 1910.1200 sets update triggers rather than a calendar interval. The main trigger is new information: employers who become newly aware of significant hazard information must revise the chemical's labels within 6 months (OSHA, 2026). The 2024 revision, with dates amended in January 2026, sets two deadlines (OSHA, 2026). Employers must update any alternative workplace labeling for newly identified hazards by 20 November 2026 for substances and by 19 May 2028 for mixtures (OSHA, 2026). As of 13 October 2026, the 20 November 2026 substances deadline has not passed, so audit decanted single substances whose supplier SDS changed under the 2024 rules first. Training must also explain the workplace labeling system, so retrain when the label format changes (OSHA, 2026). In the EU, the Directive 98/24/EC risk assessment must be kept up to date, particularly after significant changes (Directive 98/24/EC, Article 4, 1998). An illustrative schedule is a walk-through each quarter plus a check at every SDS revision; match the interval to how often your site decants chemicals.

When should you call a specialist about secondary container labels?

Call a hazard communication specialist about secondary container labels when the SDS and the supplier label disagree, when US and EU sites share one labeling system, or when NFPA 704 or HMIS ratings carry chemicals with chronic hazards. A mismatch between SDS section 2 and the drum label can mean one is out of date or was written for another jurisdiction, and the supplier should confirm which applies. Shared US and EU systems need care because the rules differ: OSHA does not require pictograms on in-house labels (OSHA, 2026), while Directive 92/58/EEC Annex III requires CLP pictograms on containers of substances and mixtures with physical or health hazards (Directive 92/58/EEC Annex III, 2014). Rating systems need a specialist because NFPA 704 covers acute health hazards only (OSHA, 2013) and the ratings do not directly correlate with HCS classifications (OSHA, 2026). An industrial hygienist or the supplier's product stewardship team can settle these. Lubinpla works cases like these from your own SDS files and site history and returns one cited document for your review, with your approval at each step. Bring the SDS, a label photo and a list of who fills and uses the container.
