Safety Data Sheet

Getting an SDS for Manganese Sulfate

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 Manganese Sulfate 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

Manganese Sulfate precautionary statements

CLP Annex VI assigns 6 precautionary statements to Manganese Sulfate. 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.

Response

What to do once exposure, spillage or fire has already happened.

Disposal

What has to happen to the contents and the empty container.

05 · Names in the regulation

Manganese Sulfate 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.

09 · Questions

Manganese Sulfate — frequently asked questions

What is the CAS number of Manganese Sulfate?

The CAS number of Manganese Sulfate is 7785-87-7. Its EC number is 232-089-9.

What is the chemical formula of Manganese Sulfate?

The molecular formula of Manganese Sulfate is MnO4S and its molecular weight is 151 g/mol.

What does a Manganese Sulfate label have to show?

Under CLP Annex VI the label for Manganese Sulfate carries the pictograms Health hazard and Environment and the signal word is Warning.

Is Manganese Sulfate flammable?

CLP Annex VI assigns Manganese Sulfate 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 Manganese Sulfate a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Manganese Sulfate. 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 boiling point of Manganese Sulfate?

The boiling point reported for Manganese Sulfate is 850 °C (1562 °F) (HSDB).

What is the melting point of Manganese Sulfate?

The melting point reported for Manganese Sulfate is 700 °C (1292 °F) (HSDB).
