Safety Data Sheet
Getting an SDS for Barium Carbonate
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 Carbonate 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 Carbonate precautionary statements
CLP Annex VI assigns 4 precautionary statements to Barium Carbonate. 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 Carbonate 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 Carbonate reactivity
Salts, basic, such as BARIUM CARBONATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

What does a Barium Carbonate label have to show?
Under CLP Annex VI the label for Barium Carbonate carries the pictogram Exclamation mark and the signal word is Warning.
Is Barium Carbonate flammable?
CLP Annex VI assigns Barium Carbonate 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 Carbonate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Barium Carbonate. 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 melting point of Barium Carbonate?
The melting point reported for Barium Carbonate is 1300 °C (2372 °F), above this value (ICSC).
How should Barium Carbonate be stored?
Separated from bromotrifluoride, strong acids, food and feedstuffs. (Hazardous Substances Data Bank (HSDB))
