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

Vamidothion health hazards and exposure limits
Vamidothion hazard summary
A cholinesterase inhibitor that may have nervous system effects causing convulsions and respiratory failure; Can be absorbed through skin; [ICSC] No adverse histopathological findings, increased tumors, or signs of developmental, delayed neurological, or teratogenic toxicity; [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]

What is the CAS number of Vamidothion?
The CAS number of Vamidothion is 2275-23-2. Its EC number is 218-894-8.
What does a Vamidothion label have to show?
Under CLP Annex VI the label for Vamidothion carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Vamidothion flammable?
CLP Annex VI assigns Vamidothion 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.
Is Vamidothion a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Vamidothion. 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 melting point of Vamidothion?
The melting point reported for Vamidothion is 43 °C (109.4 °F) (HSDB).
