03 · GHS classification

Dimefox hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Dimefox hazard class and category

GHS hazard classes Dimefox 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 1 or 2 H310 GHS06

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 Dimefox

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 Dimefox 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

Dimefox precautionary statements

CLP Annex VI assigns 7 precautionary statements to Dimefox. 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

Dimefox 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.

Dimefox health hazards and exposure limits

Dimefox hazard summary

Very toxic cholinesterase inhibitor; [Merck Index] 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]

Dimefox storage and handling

Dimefox storage conditions

... Must be stored in its sealed original containers, in well-aired, fresh & dry storehouses or in shaded & possibly well-aired places. It is recommended that the product's temperature ... not exceed 25-30 °C, & keep ... away from sources of heat, free flames or spark-generating equipment. Containers must be stacked in such a way as to permit free circulation of air ... at bottom & inside of piles. Storage areas must be located at suitable distance from inhabited buildings, animal shelters, & food stores; moreover, they must be inaccessible to unauthorized persons, children, & domestic animals. /Prothoate/

Dimefox reactivity

Highly toxic fumes are given off upon decomposition of DIMEFOX with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. [EPA, 1998]. Organophosphates 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.

Is Dimefox a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Dimefox. 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.

How should Dimefox be stored?

... Must be stored in its sealed original containers, in well-aired, fresh & dry storehouses or in shaded & possibly well-aired places.
