Work Health and Safety (Labelling of Workplace Hazardous Chemicals) Code of Practice 2015

The Code ties workplace labelling to hazard classification under the Globally Harmonised System (GHS) and the WHS Regulations. Its central conceptual anchors are: (a) correct classification, (b) a defined set of label elements driven by that classification, and (c) proportionate exceptions for realistic operational constraints.

Correct classification: The Code assumes that manufacturers and importers have the primary legal duty to correctly classify a substance, mixture or article (1.3). The identity and proportion disclosure rules on labels are explicitly linked to Schedule 8 of the WHS Regulations and the GHS classifications (2.1, 2.2). For complex mixtures the Code requires determination of hazardous ingredients “so far as is reasonably practicable” and allows technical names, sub‑families or ranges where exact composition cannot be practicably disclosed (2.2).

Label elements: The Code maps GHS hazard classes and categories to required label elements: product identifier, manufacturer/importer contact, ingredient identity/proportions, hazard pictograms, hazard statements, signal word, precautionary statements, and other information including expiry date (2.1-2.4; Appendix D). It prescribes formatting conventions (signal words in bold uppercase, hazard statements bold sentence case, pictogram form and colour) and groups core elements so users can readily find the most important warnings (2.4; 4.1). Appendix D provides matrices mapping hazard categories to signal words, pictograms, hazard and precautionary statements. Appendix F contains pictograms.

Reduced labelling and special cases: The Code recognises operational realities and creates explicit reduced labelling minima for:

• Very small containers (must include product identifier, Australian manufacturer/importer details, at least a pictogram or hazard statement and as much as reasonably practicable, 3.1).
• Research chemicals or samples for analysis (product identifier and pictogram or hazard statement minimum; must be correctly classified, 3.2).
• Decanted/transferred chemicals (if not used immediately or supplied onward, minimum label with product identifier and pictogram/hazard statement; permanent labelling is required where decanting is routine and the container is reused for the same chemical, 3.3).
• In‑workplace materials not supplied to another workplace if hazards are known to workers (minimum information product identifier + pictogram/hazard statement, 3.4).
• Hazardous waste and explosives (specific minimums and cross‑references to transport/Explosives Code for physical hazards, 3.5-3.6).
• Dangerous goods in transit (inner packaging may use GHS; in‑transit items are outside workplace labelling requirements; workplaces must add supplementary panels to meet chronic health information when required, 3.7).
• Consumer products and agricultural/veterinary chemicals (consumer household sized product labels under SUSMP or APVMA labelling accepted in lieu when criteria met; APVMA labels must still include hazard and precautionary statements per WHS Regulations, 3.8-3.9).
• Nanomaterials: interim recommended phrasing where hazards are not fully characterised (3.10).

Precedence and consolidation: The Code provides rules for removing redundant elements (Appendix E). Examples show how to apply precedence, e.g., where a skull-and-crossbones pictogram applies, the exclamation mark must be omitted; where a more stringent PPE statement applies, the lesser statement should be omitted (Appendix E).

Practical implementation tools: The Code supplies a stepwise checklist (Appendix B), examples of compliant labels including multi‑panel and combined transport/workplace labels (Appendix H), and guidance on minimum pictogram/text sizes keyed to container capacity (4.2). It also directs duty holders to review and update labels when classifications change and recommends synchronising label review with SDS updates (5.2).

Taken together, these concepts operationalise the statutory labelling duties in the WHS Regulations by converting classification outcomes into a prescriptive but flexible labelling template, with explicit exception pathways and practical design rules.

The Code explicitly identifies multiple duty holders and the allocation of responsibilities among them (1.3; Scope and application). The primary groups affected are:

• Manufacturers and importers: The Code treats them as principally responsible for correct classification and for ensuring a product is correctly labelled before supply (1.3; 2.2). The label must contain Australian contact details for the manufacturer or importer (2.3) and must disclose ingredient identities/proportions per Schedule 8, unless commercial‑in‑confidence ranges are permitted and meet the Code’s conditions (2.2). A person who packages or re‑labels with their own product name is treated as a manufacturer and inherits these obligations (1.3 note).

• Suppliers: Suppliers must not supply a hazardous chemical to a workplace if they know, or ought reasonably to know, it is not correctly labelled (1.3). That places a due‑diligence burden on supply chain participants to check labels before dispatch.

• Persons conducting a business or undertaking (PCBU): At the workplace level, PCBUs must ensure hazardous chemicals used, handled or stored at the workplace are correctly labelled per Schedule 9, except where consumer product or in‑transit exceptions apply. PCBUs are responsible for labelling chemicals manufactured at the workplace or decanted/transferred from original containers (1.3; 5). PCBUs also must ensure containers are used only for the chemical specified on the label and must ensure pipe‑work is identified “so far as is reasonably practicable” (Regulation 343 referenced at 2.6; 5 and 5.1).

• Workers in laboratories and research settings: Research chemicals and samples for analysis have a reduced labelling minimum, but the Code imposes a duty to correctly classify and to label with at least a product identifier and hazard pictogram or statement (3.2). Labelling methods may extend to swing tags or rack labels in practice.

• Transporters and consignors: The Code interacts with transport regimes. Dangerous goods packaged and labelled under transport requirements are “in‑transit” and outside workplace labelling obligations while in transit; however, the workplace must apply full labelling when not in transit and may need supplementary panels to communicate chronic health hazards omitted from transport markings (3.7). The ADG Code and Explosives Code are referenced as alternative labelling regimes where applicable (3.6-3.7; Appendix G).

• Agriculture and veterinary chemical registrants and suppliers: Agricultural and veterinary chemicals must comply with APVMA labelling requirements and also include hazard and precautionary statements consistent with WHS classifications (3.9). The Code notes that some WHS hazard statements may not be required by APVMA law and instructs manufacturers/importers to include any additional WHS-required hazard/precautionary statements that are not contrary to APVMA information.

• Waste handlers: For hazardous wastes, labels must, as far as reasonably practicable, identify and classify wastes and include specific minimum information (product identifier, Australian contact details, pictogram and hazard statement) plus as much information about components, proportions and precautions as available (3.5).

• Regulators and inspectors: While not a “who it affects” in the private sense, the Code is framed for use by inspectors and courts. The Foreword explicitly states that codes are admissible in court and may be referenced in issuing improvement or prohibition notices.

Who pays and who decides: The economic costs of compliance fall mainly on manufacturers/importers (classification and initial labelling), suppliers (supply‑chain checks) and PCBUs (workplace labelling, decanting procedures, pipe identification, training). Decisions about label content and the use of reduced labelling options are made by the manufacturer/importer for supplied containers, and by the PCBU for decanted/onsite manufactured chemicals; the Code sets out the criteria that trigger those choices (e.g., size of container, whether used immediately, whether supplied to another workplace, whether in transit). The Code also creates opportunities for commercially confidential ingredient ranges (2.2), allowing manufacturers to avoid revealing exact concentrations within specified bands, subject to the Code’s conditions.

The Code explicates, interprets and operationalises duties that are established in the WHS Act and Regulations. It does not itself create criminal penalties; rather it guides how duty holders can meet their legal obligations. Key duties and related practical rights or options are:

Duties imposed or affirmed

• Manufacturers and importers must ensure correct classification and that hazardous chemicals are correctly labelled before supply (1.3; 2.2). The Code requires the product identifier to match that in the SDS (2.2). A person who re‑labels and packages under their own product name is treated as a manufacturer and takes on the same duties (1.3 note).
• Suppliers must not supply hazardous chemicals that they know or ought reasonably to know are not correctly labelled (1.3).
• PCBUs at the workplace must ensure hazardous chemicals used, handled or stored there are correctly labelled in accordance with Schedule 9, except in defined exceptions such as consumer household quantities and in‑transit containers (1.3; 2.1; 3.7-3.8).
• PCBUs who manufacture hazardous chemicals at the workplace or decant/transfer a hazardous chemical must ensure the container is correctly labelled (Regulation 342 referenced at 5).
• PCBUs must ensure, so far as is reasonably practicable, that hazardous chemicals in pipe work are identified by a label, sign or other means on or near the pipe work (Regulation 343 referenced at 2.6).
• When hazard classifications change, labels must be reviewed and amended where necessary; SDSs should be reviewed when new information is received and at least every five years (5.2).

Practical rights and permitted flexibilities

• Reduced labelling regimes: The Code specifies minimum label content for small containers (3.1), research chemicals (3.2), decanted chemicals that are used immediately (3.3), chemicals not supplied to another workplace where hazards are known (3.4), hazardous wastes where full classification is impracticable (3.5), explosives and dangerous goods where transport codes apply (3.6-3.7).
• Commercially confidential information: Where exact ingredient proportions are commercially confidential the Code permits disclosure in specified ranges (<10%, 10-<30%, 30-60%, >60%) or narrower bands (2.2). It provides conditions for using generic names for hazardous ingredients where identity must remain confidential and exposure standards are not established, and the ingredient meets specified GHS health hazard categories.
• Use of transport labelling: For dangerous goods in transit, the Code recognises ADG/transport class labels and permits use of transport markings in lieu of GHS pictograms for transport purposes, but instructs that workplace additional health information may be required when not in transit (3.7).

Formatting, precedence and omissions

• The Code gives duty holders rules for avoiding duplication and for priority of more stringent controls (Appendix E). It specifies when pictograms should be omitted because a transport class label is used or because another pictogram takes precedence (Appendix E; Appendix G).

Label content requirements (mandatory list)

• The Code lists the elements that make a hazardous chemical “correctly labelled” under Regulation 335, Part 3 of Schedule 9 (2.1). Those elements are mandatory in the workplace regime (product identifier, Australian manufacturer/importer contact, ingredient identity/proportion per Schedule 8, pictograms, hazard statements, signal word, precautionary statements, additional hazard/first aid/emergency information, expiry date where applicable).

Operational obligations for PCBUs in workplaces

• The Code requires PCBUs to ensure that containers labelled for a hazardous chemical are used only for that chemical (5). It also defines the circumstances in which a container need not be labelled (immediate use and thorough cleaning thereafter) and provides practical steps to take when unlabelled containers are found (5.1).

Regulatory status of the Code

• The Code is approved under s274 of the WHS Act and is admissible in legal proceedings; courts may consider the Code as evidence of what is known about hazards and what is reasonably practicable (Foreword). Inspectors may refer to the Code when issuing improvement or prohibition notices (Foreword).

Rights of duty holders relating to reduced labelling are conditional: the Code sets out minimums, but the underlying WHS Regulations determine legal compliance; following the Code is generally sufficient to demonstrate compliance but is not the only way to comply. The Code uses ‘should’ to indicate recommended practice and reserves ‘must’ and ‘mandatory’ for legal requirements (Foreword).

The Code itself does not prescribe monetary fines or criminal sanctions. It functions as an approved code of practice under the WHS Act and therefore operates in enforcement and evidentiary contexts:

Evidentiary and enforcement role of the Code

• The Foreword states that an approved code of practice is admissible in court proceedings under the WHS Act and Regulations. Courts may treat the Code as evidence of what is known about a hazard, risk or control and may rely on it in determining what is “reasonably practicable” in particular circumstances (Foreword). That means the Code will be a relevant benchmark in prosecutions or civil proceedings brought under the WHS Act/Regulations where label content or labelling practices are at issue.
• Inspectors may refer to an approved Code of Practice when issuing improvement or prohibition notices (Foreword). That gives the Code operational force in regulatory inspections: failure to align workplace labelling with the Code can become the basis for improvement notices, and persistent or hazardous non‑compliance can trigger prohibition notices or enforcement action under the WHS Act/Regulations.

No standalone penalty schedule in the Code

• The Code contains no standalone penalty provisions; it interprets the labelling duties that are established in the WHS Regulations (see 2.1 referencing Regulation 335, Part 3 of Schedule 9). Any penalties arise from non‑compliance with the Act/Regulations, not the Code itself. The Code makes clear its role as guidance and as admissible evidence (Foreword).

Practical enforcement implications

• Because courts and inspectors may rely on the Code, following it is likely to be treated as strong evidence of compliance with the statutory duties. Conversely, the Code’s detailed prescriptions (for example, mandatory label elements in 2.1; minimum content for small containers at 3.1; permanent labelling for repeat decant containers at 3.3; pipe‑work identification under Regulation 343 at 2.6) provide specific expectations that regulators can point to when assessing compliance. The Code’s checklists, examples and size specifications (Appendix B; 4.2; Appendix H) further reduce ambiguity about what is “reasonably practicable”.

Inspection triggers and observable failures

• Inspectors will be able to identify observable failures: missing manufacturer/importer Australian contact details, missing product identifier or mismatch with SDS, absence of required pictograms or hazard statements, unlabeled decanted containers, use of a labelled container for different contents, missing pipe‑work identification, or labels that are illegible or not durable for the foreseeable lifetime (2.1; 4; 5.1). The Code advises immediate steps (isolate and attach product identifier) and disposal pathways for unknowns (5.1), which inspectors can use as benchmarks.

Interaction with transport, explosives and APVMA regimes

• The Code recognises other regulatory labelling regimes (ADG Code, Explosives Code, APVMA, SUSMP, TGA) and specifies when transport/other labels suffice in transit or for transport purposes, but it also requires supplementary workplace labelling where transport labels omit chronic health information (3.6-3.9; Appendix G). Inspectors will therefore check both transport and workplace labelling conformity where relevant.

In short, the Code is an enforcement lever: it provides regulators and courts with a detailed, published statement of what is known and what is reasonably practicable for labelling workplace hazardous chemicals. It does not itself fix penalty quantum, but it forms part of the body of evidence and standards relied on in enforcement under the WHS Act and WHS Regulations.

The Code explicitly situates itself alongside and in relation to several other regulatory instruments and international standards. Those interactions matter operationally because they determine when workplace labelling applies, when alternative labelling is acceptable, and where supplementary information is required.

Primary statutory regime: WHS Act and WHS Regulations

• The Code is an approved code under s274 of the WHS Act and interprets duties in the WHS Regulations. The list of mandatory label elements points directly to Regulation 335, Part 3 of Schedule 9 (2.1), and ingredient disclosure rules refer to Schedule 8 requirements (2.1-2.2). Consequently, the Code is an implementation aid rather than an alternative legal regime.

Transport law: ADG Code and UN Model Regulations

• For hazardous chemicals that are also dangerous goods, the Code recognises the Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG Code) and the UN Model Regulations (3.7; Appendix G). When goods are “in transit” the ADG Code transport markings and class labels may satisfy transport law and inner package labelling; however while in the workplace they must either be relabelled or supplemented to include health/chronic hazard information not required by transport law. The Code warns never to use both GHS pictograms and ADG class labels in the same label panel, and shows how transport and workplace panels can be combined distinctly (3.7; Appendix G; Appendix H Example 3).

Explosives law

• Explosives are subject primarily to the Australian Code for the Transport of Explosives by Road and Rail (Explosives Code). The Code requires explosives‑class chemicals (not explosive articles) to have labels complying with the Explosives Code and to include proper shipping name and UN number plus GHS health hazard information where relevant (3.6). Explosive articles follow the Explosives Code; where exposure to substances within an article could occur, the Code says include relevant health information (3.6).

Therapeutic goods, SUSMP and APVMA regimes

• The Code sets out where therapeutic goods and dual‑use products are excluded from WHS labelling because TGA or SUSMP labelling is accepted where the product is intended for patient administration or consumer household use (1.1; 3.8). Agricultural and veterinary chemicals must comply with APVMA labelling codes (Ag Labelling Code and Veterinary Labelling Code) but must also include hazard and precautionary statements consistent with WHS classifications; the Code warns manufacturers/importers to ensure any WHS-required hazard statements not covered by APVMA law are nonetheless included provided they do not contradict APVMA requirements (3.9).

International standards: GHS, IUPAC, CAS

• The Code embeds GHS labelling elements: hazard pictograms, hazard statements, signal words and precautionary statements are allocated by GHS hazard class and category; Appendix D maps categories to label elements. Ingredient identities may use IUPAC, CAS or technical names recognised by the scientific community (2.2; Appendix A). The GHS pictograms and revision references are supplied (Appendix F; Appendix I).

SDS regime

• The Code links labels to the safety data sheet (SDS) regime: the product identifier on a label must match the SDS (2.2); labels should refer to the SDS; SDSs should be reviewed when new information is received and at least every five years (5.2). The Code recommends synchronising label reviews with SDS updates.

Environmental and waste law

• The Code requires hazardous waste labels to identify and classify wastes “so far as is reasonably practicable” and to provide disposal information “in accordance with jurisdictional regulations” (3.5). It therefore anticipates interaction with environmental and waste management regimes at state/territory level.

Implication of model status and jurisdictional adoption

• The Code was developed by Safe Work Australia as a model for adoption by the Commonwealth, states and territories (Foreword). Implementation therefore depends on jurisdictional adoption. The Code functions as harmonising guidance but the text itself acknowledges the need for adoption and the possible role of jurisdictional regulations (Foreword; Scope and application).

In sum, the Code is designed to sit within an architecture of overlapping labelling, transport, therapeutic, agricultural and environmental regimes. It prescribes where substitution of other labelling regimes is acceptable and where supplementary workplace information is required. Duty holders must therefore check the interaction between this Code and transport, TGA/SUSMP, APVMA and jurisdictional waste/transport rules before concluding compliance.

The instrument text provided contains the original instrument metadata and contextual development history; it does not record subsequent formal amendments. The facts that are in the instrument itself and are relevant to amendment history are:

• Date and approval: The Code was approved by Michaelia Cash, Minister for Employment, on 17 December 2015 (3 Code of Practice Approval; signature block). The instrument name is Work Health and Safety (Labelling of Workplace Hazardous Chemicals) Code of Practice 2015 (1 Name of instrument).

• Commencement: The instrument commences on the day after it is registered on the Federal Register of Legislative Instruments (2 Commencement). The instrument does not list later amendment dates within the text provided.

• Development and endorsement: The Foreword records that Safe Work Australia developed the Code as a model code under the COAG Inter‑Governmental Agreement for Regulatory and Operational Reform in Occupational Health and Safety. A draft was released for public consultation on 7 December 2010 and the Code was endorsed by the Workplace Relations Ministers Council on 10 August 2011 (Foreword). Those development milestones show the Code’s policy timeline preceding its final approval in 2015.

• Model code relationship: The Code is explicitly described as a model Code of Practice intended for adoption by Commonwealth, state and territory governments (Foreword). That structure implies that amendments to the model Code by Safe Work Australia may be reflected differently across jurisdictions depending on their adoption schedules, but the instrument itself does not enumerate subsequent jurisdictional adoptions or amendments.

• No internal amendment schedule in instrument: The provided text contains no schedules of amendment or later modification history for this instrument; it supplies only the original approval and development background material.

How to treat this in practice:

• Confirm current version: Because the Code is a model for adoption by jurisdictions and because this instrument text is the 2015 approved version, practitioners should verify whether Safe Work Australia or any jurisdiction has subsequently updated or superseded this model, or whether state/territory regulations have incorporated variations. The Code itself lists external sources (Appendix I) which may carry updated international or domestic standards; those links should be checked for later versions.
• Trace jurisdictional adoption: The instrument is not itself a source of state regulatory amendment history; the Code’s legal effect in any location depends on each jurisdiction’s adoption of the model or their own regulations. Practitioners should consult the relevant state or territory WHS Regulations and the Federal Register of Legislative Instruments for any subsequent amendments or replacement codes.

In short, the 2015 approval and the development milestones are recorded in the instrument; the text provided contains no recorded amendments after 17 December 2015. For current legal effect and later amendments, check Safe Work Australia publications, the Federal Register and the relevant state/territory WHS instruments.

The Code text itself contains no decisions, case citations or a litigation history. The Foreword states that codes of practice are admissible in court proceedings under the WHS Act and Regulations and that courts may regard a code as evidence of the standard of knowledge and of what is reasonably practicable (Foreword). Beyond that statement, the instrument does not name any case law, judicial interpretations, or published decisions applying this Code.

Practical consequences for researching litigation:

• No cases named in the Code: The instrument does not identify any precedential rulings that interpret this Code. It therefore cannot be relied upon to indicate judicial application; research must be performed in external legal databases or jurisdictional authorities to find prosecutions or judgments in which this Code was cited.
• Evidentiary role in prosecutions: The Code’s explicit statement that it is admissible in court suggests that, in any WHS prosecution involving labelling of hazardous chemicals, prosecutors and defence counsel will commonly litigate around whether a duty holder followed the Code, and whether following or not following the Code establishes what was reasonably practicable in the circumstances. Because the Code offers detailed, prescriptive guidance (2.1; Appendices), courts may treat departures from the Code as potentially probative of non‑compliance with statutory duties, subject to the usual contest over whether the Code was the appropriate standard for the facts.
• Enforcement actions and notices: Inspectors may refer to the Code in issuing improvement or prohibition notices (Foreword). Administrative enforcement actions or notices may therefore contain references to the Code even where litigation has not yet arisen.

If the user needs a case law search on how courts and tribunals have treated this particular Code since 2015, that requires jurisdictional litigation research outside the Code text; this instrument does not provide a litigation record.

The Code is detailed, but there are multiple operational traps and nuanced edges where duty holders commonly run into problems. The Code itself highlights many of these; the following items are drawn directly from the text and focus on compliance friction points and decision points to watch.

1. Confusing legal status and evidentiary role

• The Code is guidance and not primary law, yet it is admissible in court and may be used by inspectors when issuing notices (Foreword). Some duty holders mistakenly treat the Code as optional; in practice courts and regulators will treat it as a benchmark for “reasonably practicable” measures.

2. Product identifier must match SDS

• The product identifier on the label must be identical to that in the SDS (2.2). A mismatch between label and SDS is an observable compliance failure and a likely basis for an inspector’s notice.

3. Dual‑use and consumer products exceptions are narrow

• Dual‑use products that retain SUSMP or TGA labelling escape WHS labelling only where their use and package sizes are consistent with household use. A 750 mL consumer bottle may be excluded while a 1000 L container of the same substance must be labelled under WHS (1.1, consumer examples). Similarly, APVMA‑labelled agricultural or veterinary chemicals are acceptable but the Code warns that WHS requires inclusion of any additional hazard/precautionary statements that APVMA does not require and are not contrary to APVMA law (3.9).

4. In‑transit exceptions do not remove workplace obligations once offloaded

• Containers packaged and labelled for transport can be outside workplace labelling while “in transit”, but once in the workplace they must carry the full workplace label or a supplementary panel to convey omitted chronic/health hazards (3.7). Misunderstanding “in transit” timing and the five‑day in‑transit definition in Appendix A can create non‑compliance (Appendix A definition of “In transit”).

5. Small container minimums still require prioritisation

• Small containers must include product identifier and Australian manufacturer/importer contact and at least a pictogram or hazard statement, plus as much other information as reasonably practicable (3.1). Duty holders often fail to document the prioritisation rationale, for instance why certain precautionary statements were chosen as the “most significant” hazards; the Code gives examples and recommends including critical first‑aid or emergency info where space is limited.

6. Decanting rules are operationally exacting

• A decanted container can be exempt from labelling only where the decanted chemical is used immediately, the container is not left unattended, and the container is rendered free of residue (3.3). Routine decanting into a reusable container, even if the same worker typically uses it, requires permanent full labelling and prohibits using that container for other substances (3.3; 5).

7. Commercial‑in‑confidence ranges have conditions

• Manufacturers may use concentration ranges instead of exact proportions where commercially confidential, but the Code specifies permitted ranges and allows narrower ranges; the duty to disclose hazardous ingredients “so far as reasonably practicable” remains (2.2). Using ranges without documented justification may be challenged by inspectors.

8. Precedence rules and duplication

• The Code requires omission of redundant pictograms or statements in many cases (Appendix E). Common mistakes include placing both ADG class labels and GHS pictograms on the same panel (the Code says never to do that; Appendix G) or failing to omit the exclamation mark pictogram where a skull‑and‑crossbones pictogram also applies.

9. Pipe‑work labelling is “so far as reasonably practicable”

• Regulation 343 (quoted at 2.6) requires identification of hazardous chemicals in pipe work “so far as is reasonably practicable”. The Code suggests approaches (signs, colour coding per AS 1345, schematic layouts) but does not prescribe a single method. That leaves room for inspector disagreement on adequacy; having documented procedures and reference to AS 1345 is advisable.

10. Expiry dates tied to hazard classification

• Expiry dates are required where degradation may change hazard classification (2.5). Failure to assess shelf‑life risks (e.g. peroxide formation in ethers) and to provide expiry dates may be treated as a substantive compliance gap.

11. Interaction with APVMA and SUSMP can create conflicting labelling obligations

• APVMA or SUSMP label requirements sometimes omit GHS pictograms or certain hazard statements; the Code instructs manufacturers/importers to include additional WHS hazard and precautionary statements where required and not contrary to APVMA law (3.9). Managing apparent inconsistencies requires careful legal reconciliation and sometimes supplementary labelling.

12. SDS review cadence and label sync

• SDSs must be updated when new information is received and at least every five years; the Code recommends synchronising label review with SDS updates (5.2). Failure to have processes for review leaves labels stale and liable to be challenged for not reflecting current hazard knowledge.

13. Nanomaterials interim phrasing is optional but cautionary

• For engineered nanomaterials, the Code recommends phrases such as “Contains engineered/manufactured nanomaterials. Caution: Hazards unknown.” This is recommended interim text, not a substitute for correct classification. Overreliance on such phrases without concurrent classification effort is not consistent with the Code’s duty model (3.10).

14. Waste labelling and unknown composition

• For wastes, the Code requires identification and classification so far as reasonably practicable, and expressly allows labels reflecting uncertainty (3.5). Still, inspectors will expect documented attempts at identification; simply labelling “Unknown Waste” without record of attempts to identify or arrange appropriate testing is a compliance risk.

Each of these “gotchas” is grounded in the Code text; they represent places where duty holders frequently misapply reduced labelling, fail to document justifications, or misunderstand cross‑regulatory interactions.

The Code provides explicit, practical steps and checklists for compliance. Below is an operational synthesis tied to the Code’s structure and explicit recommendations; all steps cite the relevant Code sections that prescribe or recommend the behaviour.

1. Determine whether WHS workplace labelling applies (Scope; 1.1)

• Check whether the chemical is a “hazardous chemical” under the WHS Regulations (Scope). Confirm whether it is excluded by specific regimes: consumer product in household quantities (1.1; 3.8), TGA‑labelled therapeutic goods in intended administration form (1.1), or transport in transit (3.7). If the chemical is supplied to another workplace, full workplace labelling obligations will generally apply (1.1; 3.4).

2. Ensure correct classification before labelling (1.3; 2.2)

• Manufacturers/importers must correctly classify per the GHS and Schedule 6/8 and document classification methodology (1.3; 2.2). The label must reflect that classification; the product identifier must match the SDS (2.2).

3. Use Appendix B checklist to design the label (Appendix B)

• Follow the ten steps in Appendix B: select product identifier; determine ingredients requiring disclosure (Schedule 8 rules); select applicable GHS label elements per Appendix D; combine applicable elements and apply precedence rules from Appendix E; check for special labelling situations in Chapter 3; select supplier details; determine expiry date needs (2.5); identify other relevant information (SDS reference); design layout and grouping per Chapter 4.

4. Include mandatory label elements where applicable (2.1)

• Ensure, in English, inclusion of product identifier, Australian name/address/telephone of manufacturer or importer, ingredient identity/proportion per Schedule 8, hazard pictogram(s), hazard statements, signal word and precautionary statements consistent with classification, other hazard/first‑aid/emergency information not covered, and expiry date if applicable (2.1).

5. Where space is limited follow the reduced‑labelling minima and prioritise critical information (3.1; 3.2; 3.3; 3.4)

• For very small containers include product identifier, Australian contact, at least one relevant pictogram or hazard statement and as much critical information as practicable (3.1). Prioritise the most significant route of exposure and emergency actions; document the rationale for omitted elements.

6. Decanting and transfer procedures (3.3; 5)

• If you decant and the chemical will not be used immediately or is supplied onward, label the decanted container with product identifier and pictogram/hazard statement (3.3). Where decanting is part of routine processes, put a permanent, full label on the container and restrict its use to the specified chemical only (3.3; 5).

7. Inventory, SDSs and label linkage (2.2; 5.2)

• Ensure label product identifiers match SDSs; reference the SDS on the label where possible (2.1, 2.2). Review labels whenever the SDS is updated and at least every five years as part of SDS review cycles; update the label promptly when classification changes (5.2).

8. Pipe‑work identification (Reg 343 as referenced at 2.6)

• Identify hazardous chemicals in pipe work by label, sign or other suitable means; use AS 1345‑1995 for colour coding and marking where appropriate; document the method chosen and the rationale for “so far as reasonably practicable” compliance (2.6).

9. Use precedence rules to avoid duplication and contradiction (Appendix E)

• Apply Appendix E rules: omit redundant pictograms (e.g., skull and crossbones over exclamation mark), do not mix ADG class labels and GHS pictograms on the same panel, and limit precautionary statements to six‑ten unless necessary for severity (Appendix E).

10. Export/import and transport coordination (3.7; Appendix G)

• For goods that will be transported, ensure inner packaging meets ADG Code/UN inner package GHS requirements or that separate transport panels are used. If transport labels omit chronic health information, attach a supplementary workplace panel while stored/used in the workplace.

11. Agricultural, veterinary and therapeutic goods (1.1; 3.9)

• If an APVMA label applies, ensure inclusion of any additional WHS hazard and precautionary statements required by the WHS Regulations and not contrary to APVMA requirements (3.9). For therapeutic goods, TGA labelling suffices where the product is in a form intended for patient administration; otherwise apply workplace labelling (1.1).

12. Hazardous waste labelling and unknowns (3.5; 5.1)

• For hazardous waste, label with product identifier that reflects the waste nature, include known or suspected hazardous constituents and proportions where possible, and include relevant precautionary and disposal statements “in accordance with jurisdictional regulations” (3.5). If a container is found unlabelled, attach the product identifier or mark “Caution , Do Not Use , Unknown Substance” and isolate until identified or disposed of per environmental/waste rules (5.1).

13. Documentation and records

• Keep documented rationale for generic names, commercial‑in‑confidence ranges, why reduced labelling was used, decanting procedures, SDS review dates and label updates. These records are the defence in enforcement and evidence of “reasonably practicable” steps. The Code repeatedly uses “so far as is reasonably practicable” and expects documented assessments (2.2; 3.3; 5.2).

14. Label durability, legibility and sizing (4; 4.2)

• Ensure labels are sufficiently durable for the product lifetime, legible in the normal storage position and sized to meet the Code’s minimum pictogram/text dimensions keyed to container capacity (4; 4.2). Use contrast colours and group related information for quick readability.

15. Training and worker knowledge

• Where reduced labelling is permitted because hazards are known to workers (3.4), ensure training records show workers have sufficient knowledge. The Code’s exception is conditional on workers actually knowing the hazards.

16. Seek specialist advice where necessary

• For complex mixtures, wastes, explosives, nanomaterials, or situations where competing regulatory labelling regimes intersect (APVMA, TGA, transport), take technical and legal advice. The Code offers guidance but often requires professional classification judgement and regulatory reconciliation (2.2; 3.5-3.9).

Operational checklist reference: use Appendix B step list as a quick procedural guide (Appendix B). Use example labels in Appendix H as practical templates. Where uncertain, default to including more rather than less information, and document the rationale for any omission; courts and inspectors will treat documented decision processes more favourably (Foreword).

By following the checklist, matching the SDS, applying Appendix D/E matrices, maintaining records of classification and review, and synchronising label and SDS updates, duty holders will align with the Code’s practical roadmap to compliance.
