Safety Data Sheet

Getting an SDS for Barium sulfide

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 sulfide 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 sulfide precautionary statements

CLP Annex VI assigns 10 precautionary statements to Barium sulfide. 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.

Disposal

05 · Names in the regulation

Barium sulfide 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 sulfide occupational exposure limits

US occupational exposure limits reported for Barium sulfide. PEL is enforceable (OSHA), REL is a recommendation (NIOSH), IDLH is the concentration at which escape becomes impossible without injury.
Limit Value Source
PEL 0.5 [mg/m3], as Ba Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
IDLH 50.0 [mg/m3], as Ba Haz-Map, Information on Hazardous Chemicals and Occupational Diseases

These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

08 · Questions

Barium sulfide — frequently asked questions

What is the CAS number of Barium sulfide?

The CAS number of Barium sulfide is 21109-95-5. Its EC number is 244-214-4.

What is the chemical formula of Barium sulfide?

The molecular formula of Barium sulfide is BaS and its molecular weight is 169.39 g/mol.

What does a Barium sulfide label have to show?

Under CLP Annex VI the label for Barium sulfide carries the pictograms Exclamation mark and Environment and the signal word is Warning.

Is Barium sulfide flammable?

CLP Annex VI assigns Barium sulfide 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 sulfide a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Barium sulfide. 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 sulfide?

The US occupational exposure limit reported for Barium sulfide 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.
