Safety Data Sheet
Getting an SDS for Oxydemeton-methyl
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 Oxydemeton-methyl 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
Oxydemeton-methyl precautionary statements
CLP Annex VI assigns 10 precautionary statements to Oxydemeton-methyl. 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
Oxydemeton-methyl 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.

Oxydemeton-methyl health hazards and exposure limits
Oxydemeton-methyl hazard summary
A cholinesterase inhibitor; Can be absorbed through skin; [CAMEO] A woman who was five months pregnant attempted suicide by ingestion and was hospitalized with symptoms including miosis, respiratory distress, muscular fasciculations, and coma (12 hours after admittance); Blood cholinesterase was reduced by 90%; The remainder of her pregnancy was without incident, and the baby's neurological exams at birth and 8 days later were normal; [HSDB] Occupational exposure less likely to be symptomatic or require hospitalization than exposure to other cholinesterase inhibitors; [Reference #1] 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]

Oxydemeton-methyl carcinogenicity classification
Cancer Classification: Not Likely to be Carcinogenic to 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.

What does a Oxydemeton-methyl label have to show?
Under CLP Annex VI the label for Oxydemeton-methyl carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Oxydemeton-methyl flammable?
CLP Annex VI assigns Oxydemeton-methyl 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. The flash point reported for it is 21.67 °C (71 °F), below this value (CAMEO).
Is Oxydemeton-methyl a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Oxydemeton-methyl. 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 boiling point of Oxydemeton-methyl?
The boiling point reported for Oxydemeton-methyl is 106 °C (222.8 °F), at 0.01 mmHg (reduced pressure) (HSDB).
What is the melting point of Oxydemeton-methyl?
