1,2-Dibromo-3-Chloropropane pictograms and signal word
1,2-Dibromo-3-Chloropropane hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 3 | H301 | GHS06 |
| Germ cell mutagenicity GHS chapter 3.5 | Category 1A or 1B | H340 | GHS08 |
| Carcinogenicity GHS chapter 3.6 | Category 1A or 1B | H350 | GHS08 |
| Specific target organ toxicity - repeated exposure GHS chapter 3.9 | Category 2 | H373 | GHS08 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 3 | H412 | — |
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

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 1,2-Dibromo-3-Chloropr… 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
1,2-Dibromo-3-Chloropropane precautionary statements
CLP Annex VI assigns 12 precautionary statements to 1,2-Dibromo-3-Chloropropan…. 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
1,2-Dibromo-3-Chloropropane 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
1,2-Dibromo-3-Chloropropane health hazards and exposure limits
1,2-Dibromo-3-Chloropropane hazard summary
1,2-Dibromo-3-chloropropane is a manufactured chemical and is not found naturally in the environment. It is a colorless liquid with a sharp smell. It can be tasted in water at very low concentrations. Some industries use it to make another chemical that is used to make materials that resist burning. Large amounts of 1,2-dibromo-3-chloropropane were used in the past on certain farms to kill pests that harmed crops. Farmers in all states other than Hawaii stopped using this chemical in 1979. Hawaii stopped using it in 1985. We do not know exactly how much of it is currently made or used by industry, but it is probably a small amount.

1,2-Dibromo-3-Chloropropane carcinogenicity classification
Under the conditions of this bioassay, DBCP was carcinogenic for male and female F344/N rats, including increased incidences of nasal cavity tumors and tumors of the tongue in both sexes, and cortical adenomas in the adrenal glands of females. DBCP was carcinogenic in male and female B6C3F1 mice, including increased incidences of nasal cavity tumors and lung tumors.

Cancer Classification: Group B2 Probable Human Carcinogen
Source: Hazardous Substances Data Bank (HSDB)
Evaluation: There is inadequate evidence in humans for the carcinogenicity of 1,2-dibromo-3-chloropropane. There is sufficient evidence in experimental animals for the carcinogenicity of 1,2-dibromo-3-chloropropane. Overall evaluation: 1,2-Dibromo-3-chloropropane is possibly carcinogenic to humans (Group 2B).
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.
