Safety Data Sheet
Getting an SDS for Aldrin
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 Aldrin 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
Aldrin precautionary statements
CLP Annex VI assigns 15 precautionary statements to Aldrin. 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
Aldrin 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.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Aldrin health hazards and exposure limits
Aldrin hazard summary
Not currently registered or used in the USA, Aldrin converts to dieldrin in the body and in the environment. High-dose animal studies show that organochlorine insecticides can cause liver injury. [LaDou, p. 593] No evidence of hepatic injury in humans as the result of environmental contamination. [Zimmerman, p. 414] See ATSDR ToxProfiles.

Aldrin carcinogenicity classification
Studied by the US National Toxicology Program: TR-021: Bioassays of Aldrin and Dieldrin for Possible Carcinogenicity (CASRN 309-00-2) (CASRN 60-57-1) (1978 )
Inadequate evidence of carcinogenicity in humans. Limited evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 3: The agent is not classifiable as to its carcinogenicity to humans.

Cancer Classification: Group B2 Probable Human Carcinogen

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.
