| GHS signal word | Danger |
|---|---|
| Hazard classification | Flam. Liq. 3 — H226; Skin Corr. 1A — H314; Eye Dam. 1 — H318 (EU harmonised, CLP Annex VI index 607-002-00-6; the Annex VI specific concentration limits place 90% and above into Skin Corr. 1A and 25% and above into Eye Dam. 1, so 99.8% carries both); Met. Corr. 1 — H290 (supplier self-classification, not in Annex VI) |
| Substance | Acetic Acid Glacial |

| Composition | 99.8% min |
| Eye contact | Rinse immediately with plenty of gently flowing water for at least 15 minutes, holding the eyelids apart; remove contact lenses if easy to do and continue rinsing. Do not use any neutralising agent. Refer immediately for ophthalmological attention and continue irrigation during transport — glacial acetic acid causes serious, potentially permanent eye damage. |
|---|---|
| Skin contact | Remove contaminated clothing while flushing, rinse the skin with plenty of water and then wash with water and soap for at least 15 minutes (ILO ICSC 0363). Do not apply neutralising agents. Refer for medical attention; glacial acetic acid causes deep chemical burns and the injury is often more severe than the initial appearance suggests. |
| Inhalation | Move the casualty to fresh air, keep at rest in a half-upright position and give oxygen if breathing is difficult. Refer immediately for medical attention (ILO ICSC 0363). Concentrated vapour can cause airway burns and delayed pulmonary oedema, so medical observation is needed even if the person seems to recover. |
| Ingestion | Rinse the mouth with water. Do NOT induce vomiting — re-exposure of the oesophagus and the aspiration risk make vomiting dangerous. Do not give sodium bicarbonate or other neutralising agents. If the casualty is fully conscious and ingestion occurred within the last few minutes, a small amount of water may be given to dilute (ILO ICSC 0363). Give nothing by mouth to an unconscious person. Refer immediately for medical attention. |
| Flash point | 39 C (closed cup) — ILO ICSC 0363 and neofroxx SDS. Explosive limits 6.0-17 vol% in air; auto-ignition 485 C (ILO ICSC 0363) |
|---|---|
| Suitable extinguishing media | This material has a flash point and burns. Use alcohol-resistant foam, dry chemical powder or carbon dioxide; water spray or fog to cool surrounding surfaces and containers. Confirm the medium against the producer’s safety data sheet for the grade supplied. |
| Unsuitable extinguishing media | Do not use a high-pressure water jet: it will spread the material and the fire. A vapour flash-back to the source and re-ignition of cooled but still-hot material are both foreseeable; do not approach a container that may be pressurised or a pool fire without cover. |
| Special hazards arising from the substance | Hazardous gases and decomposition products may be formed in a fire, from this substance or from its packaging and the materials stored with it. Packaging and pallets are themselves a substantial fire load. |
| Advice for fire-fighters | Fire-fighters must wear self-contained breathing apparatus and full protective clothing. Keep unnecessary personnel away and upwind. Prevent firefighting run-off from entering drains, surface water or groundwater. |
Keep unnecessary personnel away and upwind, and ventilate. Wear the protective equipment in section 8, including respiratory protection, before approaching. Eliminate ignition sources and prohibit smoking before approaching. Avoid raising dust, and never blow a spilled powder down with compressed air. Dry-collect — vacuum with a HEPA-filtered unit, or sweep gently without raising dust — into labelled, closable containers for disposal under section 13. A spill inside a vessel, tank, silo, container or pit is a confined-space job: test the atmosphere and work under permit. A fine powder makes a floor slippery, especially once wet, so treat every wetted surface as slippery until it has been washed and dried. Prevent entry to drains, surface water and groundwater. Do not return spilled material to the original container; a damaged bag should be overpacked into a labelled outer rather than decanted into an unmarked one.
• The name is literal — glacial acetic acid freezes just below normal room temperature, around 16–17°C. Drums stored outside in a north Indian winter will solidify and have to be warmed before use. Plan indoor storage or a warm store if you buy through the cold months.
• It is flammable as well as corrosive, and the flash point — about 39 °C closed cup — matters more in India than the number suggests. An unshaded godown in Gujarat or Rajasthan comfortably exceeds that on a May afternoon, which means the vapour above the drums can sit in the flammable range at storage temperature. Keep it in a shaded, ventilated flammables store with rated electricals and no ignition sources.
• UN 2789, Class 8 corrosive with a Class 3 flammable subsidiary risk, Packing Group II — corrosive is the primary class. That is what the driver's paperwork, the drum label and the vehicle placard hang on, so it is worth getting right.
• Stainless steel, glass and suitable plastics are fine. It attacks many common metals, so check before piping it through anything unusual.
Storage: Store in a fireproof, well-ventilated store approved for flammable liquids, separated from food and feedstuffs, strong oxidisers, strong acids and strong bases (ILO ICSC 0363). Keep away from all ignition sources; earth and bond containers and equipment during transfer, as the vapour is heavier than air and can travel to a remote ignition source. Use 304/316 stainless steel, glass or compatible plastics; avoid ordinary carbon steel and unsuitable elastomers. Keep containers tightly closed and protected from sunlight. Note that the product solidifies below about 16 C, so drums may need a warm store or gentle warming — never heat with a direct flame or a hot plate.
Engineering controls. Enclose every transfer, tipping, bag-slitting and sampling point and fit local exhaust extraction at each, and keep airborne concentrations below the limit in force at the place of use. Provide an eyewash within reach of the working position, and a safety shower wherever the material is classified corrosive or irritant or is handled in quantity. Do not eat, drink or smoke in the handling area; wash before breaks. Where no limit is stated above, occupational exposure limits vary by jurisdiction: check the limit in force at the place of use and the producer’s sheet for the grade supplied, and record which value your assessment adopted. Select eye, skin and respiratory protection on the strength of a measured or modelled exposure assessment, not on this sheet alone.

The health hazards classified for this substance are listed in section 2, and the corresponding first-aid measures in section 4. Numerical toxicological endpoints are not reproduced here: refer to the producer's safety data sheet for the grade supplied, and to the ECHA and PubChem entries for the substance.
Where section 2 or section 14 classifies this substance as hazardous to the aquatic environment, prevent any release to drains, surface water or groundwater and treat aqueous effluent before discharge. Otherwise, refer to the producer's sheet.
Dispose of the substance and its container through an authorised facility under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 where the waste is scheduled under those Rules, and otherwise as non-hazardous industrial waste, in each case under the conditions of the State Pollution Control Board consent in force at the site. Whether a particular waste stream is scheduled depends on the substance and on what it has been mixed with, so classify the waste before consigning it. Do not reuse empty containers for any other purpose.
| UN number | UN 2789 |
|---|---|
| Class | 8 (3) — Class 8 corrosive with a Class 3 flammable-liquid subsidiary hazard |
| Packing group | II |
| Proper shipping name | ACETIC ACID, GLACIAL |
Supply in India is subject to the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989 where the substance is scheduled, and to any product-specific licensing named on the product page. Classification and labelling follow the GHS as adopted in the jurisdiction of use.
Note: This is a Class 8 corrosive with a Class 3 flammable subsidiary hazard — it is frequently mis-declared as Class 3 only, which loses the corrosive label and the PG II packing requirements. UN 2789 covers glacial acetic acid and acetic acid solutions with more than 80% acid by mass. Weaker solutions use a different UN number: UN 2790 ACETIC ACID SOLUTION with more than 50% but not more than 80% acid by mass is Class 8, PG II, and UN 2790 with not less than 10% but not more than 50% acid is Class 8, PG III. 'Glacial' means substantially anhydrous, not a grade of purity — the acid freezes at about 16.6 C and will solidify in drums during an Indian winter or in a cold store, which is normal and reversible. The flash point of 39 C is only a little above ambient in much of India for much of the year, so the vapour space of a warm drum can be within the explosive range; treat it as a flammable liquid in handling, not merely as an acid. Diluted acetic acid is ordinary vinegar, but do not let that familiarity carry over — at 99.8% the material causes full-thickness burns.
