Safety Data Sheet
Getting an SDS for Dinoseb
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 Dinoseb 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
Dinoseb precautionary statements
CLP Annex VI assigns 15 precautionary statements to Dinoseb. 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
Dinoseb 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
Dinoseb health hazards and exposure limits
Dinoseb hazard summary
The pathophysiology, like that of pentachlorophenol, involves the uncoupling of oxidative phosphorylation. Yellow stains appear on the skin after dermal contact with the nitroaromatic herbicides. Fatal poisoning can occur after dermal absorption. Cataracts have been reported in animal experiments and after occupational exposure. In severe poisoning, these herbicides can cause injury to the liver and kidneys. [EPA Pesticides, p. 104-5] An eye irritant; Can be absorbed through skin; Short-term exposure may have effects on the GI tract and CNS; Prolonged or repeated exposure may affect the kidneys, liver, blood, immune system, and eyes (cataract); Aerosol exposure in hot environments may result in death; May be a reproductive toxicant in humans; [ICSC] A powerful oxidizing agent and explosive; Extremely toxic (enhanced by high ambient temperature and physical activity); [CAMEO]

Dinoseb carcinogenicity classification
Cancer Classification: Group C Possible 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.

Dinoseb reactivity
DINOSEB is a powerful oxidizing agent. (NTP, 1992). It is dangerously explosive. When not water wet it is a high explosive. Dry, the material is easily ignited and it will burn very vigorously. On decomposition, nitro compounds such as this emit toxic fumes. Appear to be stable in acid solution, but are susceptible to decomposition by ultraviolet radiation in alkaline solution. [EPA, 1998].

What does a Dinoseb label have to show?
Under CLP Annex VI the label for Dinoseb carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.
Is Dinoseb flammable?

Is Dinoseb a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Dinoseb. 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 Dinoseb?
The boiling point reported for Dinoseb is 332 °C (629.6 °F) (ICSC).
What is the melting point of Dinoseb?
The melting point reported for Dinoseb is 40 °C (104 °F) (DOE PAC).
How should Dinoseb be stored?
MATERIALS WHICH ARE TOXIC AS STORED OR WHICH CAN DECOMPOSE INTO TOXIC COMPONENTS ...
