Safety Data Sheet

Getting an SDS for Pirimiphos-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 Pirimiphos-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

Pirimiphos-Ethyl precautionary statements

CLP Annex VI assigns 11 precautionary statements to Pirimiphos-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.

05 · Names in the regulation

Pirimiphos-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.

Pirimiphos-Ethyl health hazards and exposure limits

Pirimiphos-Ethyl hazard summary

A cholinesterase inhibitor; Can be absorbed through skin; [CAMEO] No effects observed besides inhibition of cholinesterase in 90 day animal feeding studies; No skin irritation or sensitization observed in rabbits; [HSDB] 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]

Pirimiphos-Ethyl reactivity

Organophosphates, such as PIRIMIFOS-ETHYL, 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.
