Chlorfenvinphos hazard class and category

GHS hazard classes Chlorfenvinphos falls into
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.

Safety Data Sheet

Getting an SDS for Chlorfenvinphos

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 Chlorfenvinphos 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

Chlorfenvinphos precautionary statements

CLP Annex VI assigns 10 precautionary statements to Chlorfenvinphos. 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.

05 · Names in the regulation

Chlorfenvinphos 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.

07 · Health hazards

Chlorfenvinphos health hazards and exposure limits

Chlorfenvinphos hazard summary

Chlorfenvinphos is an insecticide that is a colorless liquid with a mild odor. It was commonly used until 1991 when all products containing chlorfenvinphos as an active ingredient were canceled in the United States. Commercial preparations commonly sold in stores were usually 90% chlorfenvinphos. Most of the chlorfenvinphos used was in liquid form. Chlorfenvinphos was widely used to control household pests such as flies, fleas, and mice. The chemical is manufactured and does not occur naturally in the environment. It was sold under common trade names including Birlane®, Dermaton®, Sapercon®, Steladone®, and Supona®. Use of trade names is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry, the Public Health Service, or the U.S. Department of Health and Human Services.

Chlorfenvinphos reactivity

Organophosphates, such as CHLORFENVINFOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
