Safety Data Sheet

Getting an SDS for Fenitrothion

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 Fenitrothion 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

Fenitrothion precautionary statements

CLP Annex VI assigns 7 precautionary statements to Fenitrothion. 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.

Disposal

What has to happen to the contents and the empty container.

05 · Names in the regulation

Fenitrothion 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.

Fenitrothion health hazards and exposure limits

Fenitrothion hazard summary

A skin and eye irritant; Can be absorbed through skin; A cholinesterase inhibitor that may affect the nervous system causing convulsions, respiratory failure, and death; [ICSC] Some evidence of contact dermatitis following exposure; No evidence of delayed neurotoxicity; [HSDB] A very toxic cholinesterase inhibitor that does not cause delayed neurotoxicity; [CAMEO] 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]

Fenitrothion 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.

Fenitrothion reactivity

Organophosphates, such as FENITROTHION, 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.
