03 · GHS classification
C.I. Solvent Yellow 14 hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
C.I. Solvent Yellow 14 pictograms and signal word
C.I. Solvent Yellow 14 hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
| Germ cell mutagenicity GHS chapter 3.5 | Category 2 | H341 | GHS08 |
| Carcinogenicity GHS chapter 3.6 | Category 2 | H351 | GHS08 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 4 | H413 | — |
Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.
C.I. Solvent Yellow 14 hazard statements (H-codes)

Safety Data Sheet
Getting an SDS for C.I. Solvent Yellow 14
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 C.I. Solvent Yellow 14 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
C.I. Solvent Yellow 14 precautionary statements
CLP Annex VI assigns 9 precautionary statements to C.I. Solvent Yellow 14. 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
C.I. Solvent Yellow 14 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.

C.I. Solvent Yellow 14 carcinogenicity classification
Under the conditions of this bioassay, C.I. Solvent Yellow 14 was carcinogenic in male and female F344/N rats, as evidenced by increased incidences of neoplastic nodules of the liver. C.I. Solvent Yellow 14 was not carcinogenic for B6C3F1 mice of either sex.

No data are available in humans. Limited evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 3: The agent is not classifiable as to its carcinogenicity to humans.

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.

09 · Handling and storage
C.I. Solvent Yellow 14 storage and handling
C.I. Solvent Yellow 14 reactivity
C.I. SOLVENT YELLOW 14 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This chemical is incompatible with strong oxidizing agents and strong acids (NTP, 1992).
