Safety Data Sheet
Getting an SDS for Simazine
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 Simazine 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
Simazine precautionary statements
CLP Annex VI assigns 7 precautionary statements to Simazine. 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
Simazine 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
Simazine health hazards and exposure limits
Simazine hazard summary
The major hazards encountered in the use and handling of simazine stem from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, dermal contact), exposure to this colorless to white powder may occur from its manufacture, formulation, and use as an herbicide. Effects from exposure may include eye and dermal irritation, shortness of breath, muscle spasms, ataxia, and anorexia. In activities and situations where over exposure may occur, wear a self-contained breathing apparatus and personal protective clothing. If contact should occur, immediately flush affected skin or eyes with running water for at least 15 minutes. Remove contaminated clothing and shoes at the site. While simazine does not ignite easily, it may burn with the production of irritating and poisonous gases. For fires involving simazine, extinguish with dry chemical, CO2, Halon, water spray, fog, or standard foam. Simazine may be shipped domestically via air, rail, road, and water, in containers bearing the label "Poison". Simazine should be stored in its original container, in dark, well-ventilated areas, away from heat, sparks, and other sources of ignition. Small dry spills of simazine may be placed into a clean, dry, covered container for later disposal (liquid solutions are first absorbed in sand or other noncombustible absorbent). Large liquid spills should be diked far ahead to prevent simazine from entering water sources and sewers. Before implementing land disposal of simazine, consult with regulatory agencies for guidance.

Simazine carcinogenicity classification
Cancer Classification: Not Likely to be Carcinogenic to Humans
Source: Hazardous Substances Data Bank (HSDB)
Evaluation: There is inadequate evidence in humans for the carcinogenicity of simazine. There is limited evidence in experimental animals for the carcinogenicity of simazine. Overall evaluation: Simazine is not classifiable as to its carcinogenicity to humans (Group 3).
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.
