Safety Data Sheet
Getting an SDS for Fipronil
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 Fipronil 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
Fipronil precautionary statements
CLP Annex VI assigns 14 precautionary statements to Fipronil. 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Fipronil 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.

10 · Questions
Fipronil — frequently asked questions
What is the CAS number of Fipronil?
The CAS number of Fipronil is 120068-37-3. Its EC number is 424-610-5.
What is the chemical formula of Fipronil?
The molecular formula of Fipronil is C12H4Cl2F6N4OS and its molecular weight is 437.1 g/mol.
What does a Fipronil label have to show?
Under CLP Annex VI the label for Fipronil carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.
Is Fipronil flammable?
CLP Annex VI assigns Fipronil 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 Fipronil a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Fipronil. 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 Fipronil?
The melting point reported for Fipronil is 201 °C (393.8 °F) (ICSC).
How should Fipronil be stored?
Keep container tightly closed in a dry and well-ventilated place. (Hazardous Substances Data Bank (HSDB))
