03 · GHS classification
Dimethylethylamine hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Dimethylethylamine pictograms and signal word
Dimethylethylamine hazard class and category
| 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 |
| Acute toxicity - inhalation GHS chapter 3.1 | Category 4 | H332 | GHS07 |
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
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.
Dimethylethylamine hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H225 | Highly flammable liquid and vapour. |
| H332 | Harmful if inhaled. |
| H302 | Harmful if swallowed. |
| H314 | Causes severe skin burns and eye damage. |

Safety Data Sheet
Getting an SDS for Dimethylethylamine
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 Dimethylethylamine 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
Dimethylethylamine precautionary statements
CLP Annex VI assigns 15 precautionary statements to Dimethylethylamine. 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
Dimethylethylamine 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.

Dimethylethylamine health hazards and exposure limits
Dimethylethylamine hazard summary
In an industrial hygiene survey of foundry workers, some high concentrations of dimethylethylamine were found associated with cold-box sand molding. [Appl Occup Environ Hyg 2001 Jan;16(1):66-77] Volunteers exposed to 40-50 mg/m3 for 8 hours experienced mucous membrane irritation and mild corneal edema. [Br J Ind Med 1991 Jan;48(1):26-9] Corrosive to skin; [Quick CPC] Occupational exposure to vapor reportedly causes eye irritation, visual disturbances (haze, blurred vision, lachrymation, and halo perception), and mild edema of corneal epithelium; Systemic effects reported (following suspected large releases) in foundry employees include dizziness, tightness and pain in the chest, abdominal cramps, increased heart rate, headache, and nausea; Emergency treatment: Irritants; [HSDB] Not sensitizing in guinea pig maximization test; Classified in the EU as: Causes burns; Harmful by inhalation and ingestion; Extremely flammable; [IUCLID] Causes burns; Harmful if swallowed or inhaled--can cause chemical pneumonitis; [Alfa Aesar MSDS]
