Safety Data Sheet
Getting an SDS for Ethylamine
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 Ethylamine 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
Ethylamine precautionary statements
CLP Annex VI assigns 9 precautionary statements to Ethylamine. 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.

05 · Names in the regulation
Ethylamine 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.

11 · Transport
Ethylamine 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.
The same CAS number is shipped under more than one UN number. Which entry applies follows from the form and the concentration of the consignment — read the proper shipping name, not the CAS.

What is the exposure limit for Ethylamine?
The US occupational exposure limit reported for Ethylamine is 10.0 [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 Ethylamine?
The boiling point reported for Ethylamine is 16.6 °C (61.9 °F) (HSDB).
What is the melting point of Ethylamine?
The melting point reported for Ethylamine is -81.2 °C (-114.2 °F) (HSDB).
How should Ethylamine be stored?
CLP Annex VI assigns Ethylamine the storage statement P403. Conditions for safe storage, including any incompatibilities: Keep container tightly closed in a dry and well-ventilated place. Storage class (TRGS 510): Gases (Hazardous Substances Data Bank (HSDB))
