Safety Data Sheet
Getting an SDS for Magnesium hexafluorosilica…
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 Magnesium hexafluorosi… 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
Magnesium hexafluorosilicate precautionary statements
CLP Annex VI assigns 4 precautionary statements to Magnesium hexafluorosilica…. 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
Magnesium hexafluorosilicate 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.

08 · Handling and storage
Magnesium hexafluorosilicate storage and handling
Magnesium hexafluorosilicate reactivity
MAGNESIUM FLUOROSILICATE gives basic aqueous solutions. Reacts with acids. Does not usually react as either oxidizing agents or reducing agents. It can react slowly with water to generate hydrofluoric acid, which can cause severe chemical burns and is one of the few materials that can etch glass.

09 · Questions
Magnesium hexafluorosilicate — frequently asked questions
What is the CAS number of Magnesium hexafluorosilicate?
The CAS number of Magnesium hexafluorosilicate is 16949-65-8. Its EC number is 241-022-2.
What does a Magnesium hexafluorosilicate label have to show?
Under CLP Annex VI the label for Magnesium hexafluorosilicate carries the pictogram Skull and crossbones and the signal word is Danger.
Is Magnesium hexafluorosilicate flammable?
CLP Annex VI assigns Magnesium hexafluorosilicate 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 Magnesium hexafluorosilicate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Magnesium hexafluorosilicate. 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 Magnesium hexafluorosilicate?
The US occupational exposure limit reported for Magnesium hexafluorosilicate is 2.5 [mg/m3], as F (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.
