Safety Data Sheet

Getting an SDS for Prallethrin

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 Prallethrin 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

Prallethrin precautionary statements

CLP Annex VI assigns 11 precautionary statements to Prallethrin. 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.

05 · Names in the regulation

Prallethrin 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 Prallethrin label have to show?

Under CLP Annex VI the label for Prallethrin carries the pictograms Skull and crossbones and Environment and the signal word is Danger.

Is Prallethrin flammable?

CLP Annex VI assigns Prallethrin 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 139 °C (282.2 °F) (HSDB).

Is Prallethrin a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Prallethrin. 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 Prallethrin?

The boiling point reported for Prallethrin is 313.5 °C (596.3 °F), at 760 mmHg (HSDB).

What is the melting point of Prallethrin?

The melting point reported for Prallethrin is Liquid at room temperatures (HSDB).

How should Prallethrin be stored?

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature: 2 - 8 °C. (Hazardous Substances Data Bank (HSDB))
