| Target Audience | WHS managers, safety officers, chemical store managers, EHS professionals |
| Key Entities | Safe Work Australia, model WHS Regulations Part 7.1, Preparation of Safety Data Sheets for Hazardous Chemicals Code of Practice |
| Regulations & Standards | Model WHS Regulations reg. 346 — chemical register required; reg. 333 — current SDS must be available; Preparation of SDS Code of Practice 2020; GHS (GHS 7 adopted in Australia) |
| Key Fact 1 | The SDS for a hazardous chemical must be no more than 5 years old at the time of use under Australian WHS Regulations — older SDS must be replaced with current versions from the manufacturer. |
| Key Fact 2 | The chemical register must include all hazardous chemicals present at the workplace in quantities exceeding the minor quantity threshold — not just chemicals in significant use. |
| Key Fact 3 | GHS Section 8 of the SDS is particularly critical for occupational hygiene — it contains the WES values and biological exposure indices applicable to each substance. |

Workplace Chemical Register and SDS Management: Legal Requirements in Australia
A current, accurate chemical register and Safety Data Sheet (SDS) library are not administrative courtesies — they are legal requirements under Australian WHS Regulations that support hazard identification, risk assessment, exposure monitoring, emergency response and worker information. A workplace that cannot quickly produce an SDS for any chemical in use, or that maintains a chemical register with gaps, is both legally exposed and operationally vulnerable in an emergency.
What Is a Hazardous Chemical?
Under the model WHS Regulations, a hazardous chemical is a substance, mixture or article that satisfies the criteria for one or more hazard classes in the Globally Harmonised System of Classification and Labelling of Chemicals (GHS). This includes: chemicals classified as toxic, harmful or irritant; substances with Workplace Exposure Standards (WES values); carcinogens, mutagens and reproductive toxins; and substances that are a physical hazard (flammable, explosive, oxidising). Many everyday chemical products — paints, solvents, adhesives, cleaning chemicals, cutting fluids — are classified hazardous chemicals under GHS.
Chemical Register Requirements
Regulation 346 requires the PCBU to ensure a register is prepared and maintained for the workplace. The register must include:
- Product name of every hazardous chemical at the workplace
- A copy of the current SDS, or information about where the SDS is located
- The hazard classification of each chemical (GHS hazard classes)
- The quantity of each chemical present or used
- The location where the chemical is used or stored
The register must be readily accessible to workers, their health and safety representatives, and emergency services. “Readily accessible” means available at the worksite — not locked away in a manager’s office or only accessible online from a desktop computer when workers are performing tasks in the field.
SDS Currency Requirements
Under regulation 333, a PCBU must ensure that a current SDS is available for each hazardous chemical. “Current” means:
- Prepared or reviewed within the last 5 years
- Sourced directly from the manufacturer or importer of the product (not third-party databases that may not have the most recent version)
- In the format prescribed by the GHS (16 sections, in order)
Chemicals that were classified under the previous NOHSC Criteria before GHS adoption may have SDS in the old format. Where a current GHS-format SDS is available from the manufacturer, it should replace old-format SDS. Where only old-format SDS are available (discontinued products, legacy stock), the PCBU must still ensure the hazard information is current and accurate.
GHS SDS Structure: The 16 Sections
The GHS specifies a mandatory 16-section SDS structure. For occupational hygiene, the most critical sections are:
- Section 2 — Hazard Identification: GHS classification and hazard statements. Identifies carcinogenicity, sensitisation, reproductive toxicity and other health hazard classifications
- Section 8 — Exposure Controls/Personal Protection: Contains WES values (Australian and international), biological exposure indices, recommended engineering controls (LEV specifications), and RPE requirements. This section directly informs the occupational hygiene risk assessment
- Section 11 — Toxicological Information: Detailed toxicity data — LD50, LC50, target organ effects, carcinogenicity classification (IARC, NTP, ACGIH A1/A2)
- Section 15 — Regulatory Information: Australian and international regulatory status — Schedule 10 (prohibited substances), Schedule 11 (restricted substances), dangerous goods classification
Using SDS for Occupational Hygiene Risk Assessment
The SDS is the starting point — not the endpoint — for chemical risk assessment. Common errors in interpreting SDS for hygiene purposes:
- Treating the WES in Section 8 as a safe level: The WES is the legal limit, not a no-effect level. ALARP reduction below the WES is still required
- Ignoring products with no WES: Many hazardous chemicals do not have an established WES. Absence of a WES does not mean the chemical is safe — a risk assessment is required using all available toxicological data
- Accepting that Section 8 controls are adequate: Many SDS give generic “provide ventilation” guidance. Site-specific conditions require site-specific control assessment
- Not checking the Section 2 classification: A product classified as a Category 1 carcinogen (H350) or reproductive toxin (H360) triggers stricter management obligations than products with only irritant classifications
Digital SDS Management Tools
Several software platforms manage SDS libraries and chemical registers, including chemical safety modules in safety management platforms (MYOSH, EHS Insight, Cority) and dedicated SDS management tools (Chemwatch, ecoPortal, SafetyDocs). Features to look for include: automatic SDS update notifications from manufacturers, multi-site support, mobile access for workers in the field, integration with chemical risk assessment workflows, and report generation for regulatory inspection readiness.
