03 · GHS classification
Azinphos-Ethyl hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Azinphos-Ethyl pictograms and signal word
Azinphos-Ethyl hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 1 or 2 | H300 | GHS06 |
| Acute toxicity - dermal GHS chapter 3.1 | Category 3 | H311 | GHS06 |
| Hazardous to the aquatic environment - acute GHS chapter 4.1 | Category 1 | H400 | GHS09 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 1 | H410 | 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.
Azinphos-Ethyl hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H300 | Fatal if swallowed. |
| H311 | Toxic in contact with skin. |
| H400 | Very toxic to aquatic life. |
| H410 | Very toxic to aquatic life with long lasting effects. |

Safety Data Sheet
Getting an SDS for Azinphos-Ethyl
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 Azinphos-Ethyl 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
Azinphos-Ethyl precautionary statements
CLP Annex VI assigns 10 precautionary statements to Azinphos-Ethyl. 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
Azinphos-Ethyl 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.

Azinphos-Ethyl health hazards and exposure limits
Azinphos-Ethyl hazard summary
Effects in high dose animal studies include depression of cholinesterase activity; [HSDB] Extremely toxic cholinesterase inhibitor that may cause death as a result of minor exposure to small amounts; [CAMEO] Toxic by ingestion, skin absorption, or inhalation; [INCHEM PDS: Azinphos-ethyl - 1994] May cause irritation; Effects in high dose animal studies include convulsions; [MSDSonline] The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline. [TLVs and BEIs]

Azinphos-Ethyl storage and handling
Azinphos-Ethyl storage conditions
Store in original container, preferably in locked storage, away from children, food, or feed.

Azinphos-Ethyl incompatible materials
Contact with oxidizers may cause the release of phosphorous oxides. Contact with strong reducing agents, such as hydrides, may cause the formation of flammable and toxic phosphine gas.

Azinphos-Ethyl reactivity
The BPS Pesticide incident in Helena resulted in an explosion and death of three firemen. The burning of a 1,000 pound sack of Azinphos Methyl or the flashing of Maneb which was present on the facility may have caused the explosion. Azinphos Ethyl may behave similarly. At elevated temperatures, it will decompose generating toxic gases.

What does a Azinphos-Ethyl label have to show?
Under CLP Annex VI the label for Azinphos-Ethyl carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Azinphos-Ethyl flammable?

Is Azinphos-Ethyl a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Azinphos-Ethyl. 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 Azinphos-Ethyl?
The boiling point reported for Azinphos-Ethyl is 111 °C (231.8 °F), at 0.001 mmHg (reduced pressure) (HSDB).

How should Azinphos-Ethyl be stored?
Store in original container, preferably in locked storage, away from children, food, or feed. (Hazardous Substances Data Bank (HSDB))
