03 · GHS classification
Barium perchlorate hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Barium perchlorate pictograms and signal word
Barium perchlorate hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Oxidising liquids or Oxidising solids | Category 1 | H271 | GHS03 |
| Acute toxicity - oral GHS chapter 3.1 | Category 4 | H302 | GHS07 |
| Acute toxicity - inhalation GHS chapter 3.1 | Category 4 | H332 | 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.
Barium perchlorate hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H271 | May cause fire or explosion; strong oxidiser. |
| H332 | Harmful if inhaled. |
| H302 | Harmful if swallowed. |
This page lists only the codes assigned to Barium perchlorate. The full reference lives on the hazard statements hub, the precautionary statements hub and the GHS pictograms hub.
Safety Data Sheet
Getting an SDS for Barium perchlorate
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 Barium perchlorate 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
Barium perchlorate precautionary statements
CLP Annex VI assigns 7 precautionary statements to Barium perchlorate. 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
Barium perchlorate 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.

Barium perchlorate properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.

Barium perchlorate storage and handling
Barium perchlorate reactivity
Reflux heating of BARIUM PERCHLORATE with alcohols yields perchlorate esters, which are highly explosive [Kirk-Othmer 2nd ed. 5:75 1963]. A strong oxidizing agent. May react violently with organic materials.

10 · Transport
Barium perchlorate UN number and transport classification
Transport classification is a separate system from the GHS classification above. It decides how a package is marked and how a load may be carried; it does not follow from the workplace label, and the workplace label does not follow from it. The entries below are linked by CAS number, never by name.
The same CAS number is shipped under more than one UN number. Which entry applies follows from the form and the concentration of the consignment — read the proper shipping name, not the CAS.

11 · Questions
Barium perchlorate — frequently asked questions
What is the CAS number of Barium perchlorate?
The CAS number of Barium perchlorate is 13465-95-7. Its EC number is 236-710-4.
What does a Barium perchlorate label have to show?
Under CLP Annex VI the label for Barium perchlorate carries the pictograms Flame over circle and Exclamation mark and the signal word is Danger.
Is Barium perchlorate flammable?
CLP Annex VI assigns Barium perchlorate 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 Barium perchlorate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Barium perchlorate. 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 Barium perchlorate?
The US occupational exposure limit reported for Barium perchlorate is 0.5 [mg/m3], as Ba (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.
What is the melting point of Barium perchlorate?
The melting point reported for Barium perchlorate is 505 °C (941 °F) (CAMEO).
