Safety Data Sheet
Getting an SDS for Allyl Alcohol
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 Allyl Alcohol 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
Allyl Alcohol precautionary statements
CLP Annex VI assigns 24 precautionary statements to Allyl Alcohol. 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
Allyl Alcohol 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.

Allyl Alcohol reactivity
ALLYL ALCOHOL presents a dangerous fire and explosion hazard when exposed to heat, flame, or oxidizing agents. Reacts violently or explosively with sulfuric acid, strong bases. Reacts violently with 2,4,6-trichloro-1,3,5-triazine and 2,4,6-tris(bromoamino)-1,3,5-triazine. Reacts with carbon tetrachloride to produce explosively unstable products [Lewis]. Mixing allyl alcohol in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, oleum, sulfuric acid [NFPA 491M. 1991].

Yes. CLP Annex VI assigns Allyl Alcohol H225 — highly flammable liquid and vapour. The flash point reported for it is 21.11 °C (70 °F) (HSDB).
Is Allyl Alcohol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Allyl Alcohol. 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 exposure limit for Allyl Alcohol?
The US occupational exposure limit reported for Allyl Alcohol is 2.0 [ppm] (Haz-Map, Information on Hazardous Chemicals and Occupational Diseases). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.
What is the boiling point of Allyl Alcohol?
The boiling point reported for Allyl Alcohol is 96.9 °C (206.4 °F) (HSDB).
What is the melting point of Allyl Alcohol?
The melting point reported for Allyl Alcohol is -129 °C (-200.2 °F) (HSDB).
How should Allyl Alcohol be stored?
CLP Annex VI assigns Allyl Alcohol the storage statement P403. Separate from oxidizing materials. Store in a dry, cool, well-ventilated location. (Hazardous Substances Data Bank (HSDB))
