Safety Data Sheet

Getting an SDS for Octabromodiphenyl ethers

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 Octabromodiphenyl… 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

Octabromodiphenyl ethers precautionary statements

CLP Annex VI assigns 4 precautionary statements to Octabromodiphenyl ethers. 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.

05 · Names in the regulation

Octabromodiphenyl ethers 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.

What does a Octabromodiphenyl ethers label have to show?

Under CLP Annex VI the label for Octabromodiphenyl ethers carries the pictogram Health hazard and the signal word is Danger.

Is Octabromodiphenyl ethers flammable?

CLP Annex VI assigns Octabromodiphenyl ethers 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 Octabromodiphenyl ethers a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Octabromodiphenyl ethers. 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.
