Safety Data Sheet

Getting an SDS for Camphechlor (ISO)

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 Camphechlor (ISO) 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

Camphechlor (ISO) precautionary statements

CLP Annex VI assigns 16 precautionary statements to Camphechlor (ISO). 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

Camphechlor (ISO) 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.

07 · Health hazards

Camphechlor (ISO) health hazards and exposure limits

Camphechlor (ISO) hazard summary

Toxaphene was one of the most heavily used pesticides in the United States in the 1970s and early 1980s. It was used primarily to control insect pests on cotton and other crops in the southern United States. Other uses included controlling insect pests on livestock and killing unwanted fish in lakes. Toxaphene was banned for all registered uses by 1990. Toxaphene is made by reacting chlorine gas with a substance called camphene. The resulting product (toxaphene) is a mixture of hundreds of different chlorinated camphenes and related chemicals.

Camphechlor (ISO) carcinogenicity classification

IARC classification Group 2B — Possibly carcinogenic to humans
IARC monographs Volume 79: (2001) Some Thyrotropic Agents

Studied by the US National Toxicology Program: TR-037: Bioassay of Toxaphene for Possible Carcinogenicity (CASRN 8001-35-2) (1979 )

Evaluation: There is inadequate evidence in humans for the carcinogenicity of toxaphene. There is sufficient evidence in experimental animals for the carcinogenicity of toxaphene. Overall evaluation: Toxaphene is possibly carcinogenic to humans (Group 2B).

Source: Hazardous Substances Data Bank (HSDB)

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.

Camphechlor (ISO) occupational exposure limits
