03 · GHS classification

Fluoroacetic acid hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Fluoroacetic acid hazard class and category

GHS hazard classes Fluoroacetic acid falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 1 or 2 H300 GHS06
Hazardous to the aquatic environment - acute GHS chapter 4.1 Category 1 H400 GHS09

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.

Safety Data Sheet

Getting an SDS for Fluoroacetic acid

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 Fluoroacetic acid 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

Fluoroacetic acid precautionary statements

CLP Annex VI assigns 7 precautionary statements to Fluoroacetic acid. 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.

Disposal

What has to happen to the contents and the empty container.

05 · Names in the regulation

Fluoroacetic acid 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 · Transport

Fluoroacetic acid UN number and transport classification

Transport classification is a separate system from the GHS classification above. It decides how a package is marked and how a load may be carried; it does not follow from the workplace label, and the workplace label does not follow from it. The entries below are linked by CAS number, never by name.

Is Fluoroacetic acid a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Fluoroacetic acid. 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 boiling point of Fluoroacetic acid?

The boiling point reported for Fluoroacetic acid is 168 °C (334.4 °F) (HSDB).

What is the melting point of Fluoroacetic acid?

The melting point reported for Fluoroacetic acid is 35.2 °C (95.4 °F) (HSDB).

How should Fluoroacetic acid be stored?

Keep container tightly closed in a dry and well-ventilated place. Storage class (TRGS 510): Non-combustible, acute toxic Cat. 1 and 2 / very toxic hazardous materials. (Hazardous Substances Data Bank (HSDB))
