Safety Data Sheet
Getting an SDS for Fenaminosulf
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 Fenaminosulf 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
Fenaminosulf precautionary statements
CLP Annex VI assigns 10 precautionary statements to Fenaminosulf. 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
Fenaminosulf 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.

Fenaminosulf health hazards and exposure limits
Fenaminosulf carcinogenicity classification
Under the conditions of this bioassay, dietary administration of formulated fenaminosulf was not carcinogenic in either Fischer 344 rats or B6C3F1 mice.
Source: US National Toxicology Program · TR-101: Bioassay of Formulated Fenaminosulf for Possible Carcinogenicity (CASRN 140-56-7) (1978 )
Classification of carcinogenicity: 1) evidence in humans: No adequate data. 2) evidence in animals: Inadequate data. Overall summary evaluation of carcinogenic risk to humans is Group 3: The agent is not classifiable as to its carcinogenicity to humans. /From table/

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

What does a Fenaminosulf label have to show?
Under CLP Annex VI the label for Fenaminosulf carries the pictogram Skull and crossbones and the signal word is Danger.
Is Fenaminosulf flammable?

Is Fenaminosulf a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Fenaminosulf. 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. IARC places it in Group 3: not classifiable as to its carcinogenicity to humans.
What is the melting point of Fenaminosulf?
The melting point reported for Fenaminosulf is 200 °C (392 °F), decomposes (CAMEO).
