03 · GHS classification
Chloroplatinic acid hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Chloroplatinic acid pictograms and signal word
Chloroplatinic acid hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 3 | H301 | GHS06 |
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
| Respiratory sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H334 | GHS08 |
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.
Chloroplatinic acid hazard statements (H-codes)

Safety Data Sheet
Getting an SDS for Chloroplatinic acid
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Chloroplatinic acid issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
Chloroplatinic acid precautionary statements
CLP Annex VI assigns 11 precautionary statements to Chloroplatinic acid. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation
Chloroplatinic acid name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

What is the CAS number of Chloroplatinic acid?
The CAS number of Chloroplatinic acid is 16941-12-1. Its EC number is 241-010-7.
What is the chemical formula of Chloroplatinic acid?
The molecular formula of Chloroplatinic acid is Cl6H2Pt and its molecular weight is 409.8 g/mol.
What does a Chloroplatinic acid label have to show?
Under CLP Annex VI the label for Chloroplatinic acid carries the pictograms Skull and crossbones, Corrosion and Health hazard and the signal word is Danger.
Is Chloroplatinic acid flammable?
CLP Annex VI assigns Chloroplatinic acid no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.
Is Chloroplatinic acid a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Chloroplatinic acid. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
What is the exposure limit for Chloroplatinic acid?
The US occupational exposure limit reported for Chloroplatinic acid is 0.002 [mg/m3], as Pt (Haz-Map, Information on Hazardous Chemicals and Occupational Diseases). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.
