03 · GHS classification

Tolclofos-methyl hazard classification

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

Tolclofos-methyl hazard class and category

GHS hazard classes Tolclofos-methyl falls into
Hazard class Category From code Pictogram
Skin sensitisation GHS chapter 3.4 Category 1 or 1A or 1B H317 GHS07
Hazardous to the aquatic environment - acute GHS chapter 4.1 Category 1 H400 GHS09
Hazardous to the aquatic environment - chronic GHS chapter 4.1 Category 1 H410 GHS09

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 Tolclofos-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 Tolclofos-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

Tolclofos-methyl precautionary statements

CLP Annex VI assigns 8 precautionary statements to Tolclofos-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.

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

Tolclofos-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.

What does a Tolclofos-methyl label have to show?

Under CLP Annex VI the label for Tolclofos-methyl carries the pictograms Exclamation mark and Environment and the signal word is Warning.

Is Tolclofos-methyl flammable?

CLP Annex VI assigns Tolclofos-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 100 °C (212 °F), above this value (HSDB).

Is Tolclofos-methyl a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Tolclofos-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 melting point of Tolclofos-methyl?

The melting point reported for Tolclofos-methyl is 79.25 °C (174.7 °F), range, midpoint shown (HSDB).

How should Tolclofos-methyl be stored?
