tert-Butyl acrylate hazard class and category

GHS hazard classes tert-Butyl acrylate falls into
Hazard class Category From code Pictogram
Flammable liquids GHS chapter 2.6 Category 2 H225 GHS02
Acute toxicity - oral GHS chapter 3.1 Category 4 H302 GHS07

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 tert-Butyl acrylate

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 tert-Butyl acrylate 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

tert-Butyl acrylate precautionary statements

CLP Annex VI assigns 24 precautionary statements to tert-Butyl acrylate. 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.

Storage

How the container has to be kept between uses.

Disposal

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

05 · Names in the regulation

tert-Butyl acrylate 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.
