Safety Data Sheet
Getting an SDS for Ethion
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 Ethion 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
Ethion precautionary statements
CLP Annex VI assigns 11 precautionary statements to Ethion. 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
Ethion 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.

Ethion health hazards and exposure limits
Ethion hazard summary
Ethion is an organophosphate pesticide. Pure ethion is a clear to yellowish liquid with an unpleasant sulfur-like smell. It does not occur naturally in the environment. Ethion is used in agriculture, mainly to control insects on citrus trees, but also on cotton, fruit and nut trees, and some vegetables. It may also be used on lawns and turf grasses, but it is not used in the home for pest control.

Ethion carcinogenicity classification
Cancer Classification: Group E Evidence of Non-carcinogenicity for Humans
Source: Hazardous Substances Data Bank (HSDB)
An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.
Ethion occupational exposure limits
| Limit | Value | Source |
|---|---|---|
| PEL | none See Appendix G | The National Institute for Occupational Safety and Health (NIOSH) |
| REL | 0.4 mg/m³ | Occupational Safety and Health Administration (OSHA) |
| REL | TWA 0.4 mg/m3 [skin] | The National Institute for Occupational Safety and Health (NIOSH) |
| IDLH | N.D. | The National Institute for Occupational Safety and Health (NIOSH) |
These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

What does a Ethion label have to show?
Under CLP Annex VI the label for Ethion carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Ethion flammable?
CLP Annex VI assigns Ethion no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it. The flash point reported for it is 176.11 °C (349 °F) (NIOSH).
Is Ethion a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Ethion. 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 Ethion?
The US occupational exposure limit reported for Ethion is none See Appendix G (The National Institute for Occupational Safety and Health (NIOSH)). 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 Ethion?
The boiling point reported for Ethion is 150 °C (302 °F), above this value (HSDB).
What is the melting point of Ethion?
The melting point reported for Ethion is -12.22 °C (10 °F) (NIOSH).
How should Ethion be stored?
DO NOT STORE ETHION 4 EC AND 8 EC AT TEMP BELOW 0 °F AND 20 °F, RESPECTIVELY. (Hazardous Substances Data Bank (HSDB))
