Pirimicarb hazard class and category

GHS hazard classes Pirimicarb falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 3 H331 GHS06
Skin sensitisation GHS chapter 3.4 Category 1 or 1A or 1B H317 GHS07
Carcinogenicity GHS chapter 3.6 Category 2 H351 GHS08
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 Pirimicarb

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 Pirimicarb 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

Pirimicarb precautionary statements

CLP Annex VI assigns 17 precautionary statements to Pirimicarb. 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.

Disposal

05 · Names in the regulation

Pirimicarb 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.

Pirimicarb health hazards and exposure limits

Pirimicarb hazard summary

Manufacturing workers had mild carbamate insecticide poisoning from inhaling vapors after pirimicarb was heated to 65 deg C; [HSDB] See CARBAMATE INSECTICIDES.

Pirimicarb carcinogenicity classification

Cancer Classification: 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.
