Safety Data Sheet

Getting an SDS for Tris(2-chloroethyl)…

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 Tris(2-chloroethyl)… 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

Tris(2-chloroethyl) phosphate precautionary statements

CLP Annex VI assigns 11 precautionary statements to Tris(2-chloroethyl)…. 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

Tris(2-chloroethyl) phosphate 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

Tris(2-chloroethyl) phosphate health hazards and exposure limits

Tris(2-chloroethyl) phosphate hazard summary

Causes slight eye irritation; Skin absorption is minimal; In high dose animal studies, findings include testicular damage, some inhibition of cholinesterase, and central nervous system effects including seizures. CNS effects may be due to cholinesterase inhibition or direct toxicity to brain. [HSDB] The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline. [TLVs and BEIs]

Tris(2-chloroethyl) phosphate carcinogenicity classification

IARC classification Group 3 — Not classifiable as to its carcinogenicity to humans
IARC monographs Volume 48: (1990) Some Flame Retardants and Textile Chemicals, and Exposures in the Textile Manufacturing Industry; Volume 71: (1999) Re-evaluation of Some Organic Chemicals, Hydrazine and Hydrogen Peroxide (Part 1, Part 2, Part 3)

Under the conditions of these 2-year gavage studies, there was clear evidence of carcinogenic activity for male and female F344/N rats receiving tris(2-chloroethyl)phosphate as shown by increased incidences of renal tubule adenomas. Thyroid follicular cell neoplasms and mononuclear cell leukemia in male and female rats may have been related to chemical administration. There was equivocal evidence of carcinogenic activity for male B6C3F1 mice as shown by a marginally increased incidence of renal tubule cell neoplasms. There was equivocal evidence of carcinogenic activity for female B6C3F1 mice as shown by a marginally increased incidence of harderian gland adenomas.

Evaluation: No epidemiological data relevant to the carcinogenicity of tris(2-chloroethyl)phosphate were available. There is limited evidence for the carcinogenicity of tris(2-chloroethyl)phosphate in experimental animals. Overall evaluation: Tris(2-chloroethyl)phosphate is not classifiable as to its carcinogenicity to humans (Group 3).

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.
