In plain English
Every hazardous chemical used at work should come with a safety data sheet (SDS). It is a standard document with 16 sections. It says what the hazards are, how to store and handle the chemical, what to do after a spill or exposure, and how to dispose of it [1, 2].
Hazards are described using the Globally Harmonised System (GHS), an international set of rules for classifying chemicals and labelling them with symbols and set phrases [3, 4]. Australia uses the 7th edition, called GHS 7 [2].
Research peptides are a special case. Many have never had full toxicity testing, so nobody knows all their hazards. For chemicals like this, an Australian SDS can say that full hazard information is not available. It must then say that a careful, precautionary approach is needed [1].
An SDS is useful, but it is only a first step. Laboratories still need to think about how the chemical will actually be used [4].
The short version
- An SDS has 16 standard sections.
- Australia classifies hazards under GHS 7.
- “No data” is not the same as “no hazard”.
- Controls come before PPE.
Who must provide an SDS
Under the model Work Health and Safety (WHS) Regulations, manufacturers and importers must determine whether a chemical supplied to workplaces is hazardous and classify it under GHS 7 [2]. They must prepare a correct SDS for each hazardous chemical, and anyone who supplies, uses or stores a hazardous chemical must keep a copy at the workplace [5].
An Australian SDS must be in English, use Australian legal units of measurement, state the date it was last reviewed (or prepared), give the name, Australian address and business phone number of the manufacturer or importer, and give an Australian emergency phone number [1]. Manufacturers and importers must review the SDS at least once every five years [1]. An SDS prepared overseas is acceptable only if it meets the WHS Regulations, which is unlikely unless it was written for Australia [1].
The 16 sections of an SDS
| Section | Heading | What to look for in a peptide SDS |
|---|---|---|
| 1 | Identification | Product name, supplier, Australian emergency number |
| 2 | Hazard(s) identification | GHS class and category, signal word, hazard (H) and precautionary (P) statements |
| 3 | Composition and information on ingredients | Peptide identity, counter-ion, CAS number where one exists |
| 4 | First aid measures | Actions by route of exposure |
| 5 | Firefighting measures | Suitable extinguishing media |
| 6 | Accidental release measures | Spill clean-up for powder and solutions |
| 7 | Handling and storage | Temperature, light and moisture conditions; incompatibilities |
| 8 | Exposure controls and personal protection | Exposure standards (if any), engineering controls, PPE |
| 9 | Physical and chemical properties | Appearance, solubility, molecular formula and weight |
| 10 | Stability and reactivity | Conditions to avoid, hazardous decomposition products |
| 11 | Toxicological information | Data by route of exposure, or a clear statement that data is not available |
| 12 | Ecological information | Environmental hazards |
| 13 | Disposal considerations | Waste handling methods |
| 14 | Transport information | Dangerous goods classification, if any |
| 15 | Regulatory information | Relevant Australian controls |
| 16 | Any other relevant information | Revision date, abbreviations, references |
The section list follows the Safe Work Australia model Code of Practice [1].
Reading GHS classification
GHS sorts hazards into classes (for example skin corrosion, acute toxicity, flammable liquid) and categories that rank severity, where Category 1 is the most severe [1, 3]. Section 2 of the SDS and the label then carry:
- A signal word: “Danger” for more severe hazards, “Warning” for less severe ones.
- Hazard statements (H-codes): standard phrases such as H314, “Causes severe skin burns and eye damage”.
- Precautionary statements (P-codes): standard phrases on prevention, response, storage and disposal.
- Pictograms: red-bordered diamonds such as the corrosion symbol or the exclamation mark. They are optional on an Australian SDS but required on labels [1, 6].
Example: trifluoroacetic acid
Trifluoroacetic acid (TFA) is widely used in peptide synthesis and purification, and trifluoroacetate is a common peptide counter-ion. In aggregated company notifications to the European Chemicals Agency, all notifiers classified TFA as H314 (causes severe skin burns and eye damage), H332 (harmful if inhaled) and H412 (harmful to aquatic life with long-lasting effects) [7]. This classification applies to the concentrated acid. A peptide trifluoroacetate salt is a different substance with its own classification.
Peptide SDSs: when hazard data is missing
For a research chemical whose hazard properties are not fully known, the WHS Regulations accept an SDS that [1]:
- is written in English and gives the Australian manufacturer’s or importer’s details;
- states that full identification or hazard information is not available, and that a precautionary approach must be taken to handling and storage;
- states the chemical identity or structure as far as reasonably practicable;
- states any known or suspected hazards; and
- states any precautions identified.
The Code also says an SDS should distinguish clearly between “no information available” and “negative test results”, and that general statements such as “safe if properly used” with no supporting data are not acceptable [1]. An SDS reading “not classified” for a novel peptide, with no toxicology data, means the hazards are unknown, not absent.
SDSs in general can be insufficiently detailed, poorly curated or hard to search, and a 2026 review describes them as a starting point for risk assessment rather than the whole process [4].
Controlling the risks: the hierarchy of control
Australian WHS duties require risks from hazardous chemicals to be eliminated, or, if that is not reasonably practicable, minimised by working through the hierarchy of control [8]:
- Eliminate the hazard or the hazardous task.
- Substitute, isolate or engineer: use a less hazardous material, enclose the process, or use ventilation.
- Administrative controls: procedures, training, signage, restricted access.
- Personal protective equipment (PPE): the last line of protection.
Administrative controls and PPE do not control the hazard at its source and are the least effective measures when used on their own [8].
Applying this to peptide work
| Task | Main hazard | Typical controls |
|---|---|---|
| Weighing lyophilised powder | Inhaling fine, light powder of uncertain biological activity | Ventilated balance enclosure or fume cupboard; small quantities; avoid open-bench weighing of fine powders |
| Dissolving in DMSO, acetonitrile or acids | Solvent exposure; corrosive acids | Fume cupboard for volatile or corrosive solvents; check each solvent’s own SDS |
| Handling peptide synthesis reagents | Sensitisation | Coupling agents such as HATU, HBTU and HCTU are immune sensitisers; a published case series describes anaphylaxis after repeated exposure in a research laboratory [9] |
| Solutions and aliquots | Splashes, skin contact | Lab coat, safety glasses, chemical-resistant gloves |
PPE must suit the task. Glove choice depends on the chemical, because some gloves resist some solvents but not others [8]. Once a worker becomes sensitised to a chemical, its exposure standard is no longer a reliable guide, and stronger engineering controls or removal from exposure are needed [8].
Labelling, storage and waste
- Label every container. Decanted solutions and chemical waste containers must be labelled correctly. A container of unknown contents should be marked (for example “Caution—do not use: unknown substance”) and isolated until identified [8]. For peptide aliquots, a label with compound, batch, concentration, solvent, date and initials meets practical needs.
- Store by compatibility. Section 7 sets storage conditions and Section 10 lists incompatible materials. Keep acids, bases and oxidisers apart.
- Spills. A spill containment system must describe how to contain, clean up and dispose of a spill, and must not bring incompatible chemicals together [8]. Wet-wipe powder spills rather than sweeping, to avoid raising dust.
- Waste. Follow Section 13 and local waste requirements. Expired chemicals should not be used and should be disposed of according to the manufacturer’s instructions and local laws [8]. Segregate solvent waste, aqueous waste and contaminated solids such as tips, tubes and broken glass.
Exposure standards are changing
Most peptides have no workplace exposure standard. For solvents and reagents that do, Australia is moving from workplace exposure standards (WES) to workplace exposure limits (WELs), which take effect on 1 December 2026. Until then, the existing WES continue to apply [2].
What this means in Australia
- WHS law applies to laboratories. The model WHS laws set duties for anyone who manufactures, imports, supplies, uses or stores hazardous chemicals. Safe Work Australia develops the model laws, while the Commonwealth, states and territories regulate and enforce them, so a model Code of Practice has legal effect only where a jurisdiction has approved it [1, 8].
- An SDS does not change therapeutic-goods status. Unapproved peptide products are not entered on the Australian Register of Therapeutic Goods (ARTG) and have not been assessed by the TGA [10].
- Scheduling. Several peptides are named in the current Poisons Standard (October 2026), some as Schedule 4 (prescription-only) and Appendix D, clause 5 (possession without authority is illegal) [11]. Workplace safety compliance does not authorise possession.
- Labels don’t change status. The TGA has stated that a “research use only” disclaimer does not make supply lawful, change regulatory status, permit importation, or remove advertising or supply obligations [10].
This is general information, not legal advice. Laws change; check the current Poisons Standard and TGA guidance.
Frequently asked questions
What is a safety data sheet?
An SDS is a standardised 16-section document that describes a chemical’s hazards and how to handle, store, transport and dispose of it, plus first aid and emergency measures [1].
Which version of the GHS does Australia use?
Australia uses the 7th revised edition (GHS 7). From 1 January 2023, manufacturers and importers can only use GHS 7 to classify, label and prepare SDSs for hazardous chemicals [1, 2].
What if a peptide’s SDS says “no data available”?
It means the hazards have not been fully determined. For research chemicals, Australian rules require the SDS to call for a precautionary approach to handling and storage [1].
Do peptides need to be handled in a fume cupboard?
It depends on the task and the risk assessment. Weighing fine powders of uncertain activity and handling volatile or corrosive solvents are common reasons to use a ventilated enclosure [8].
How often must an SDS be reviewed?
Manufacturers and importers must review an SDS at least once every five years, and amend it whenever new hazard information becomes available [1].
