NOTE! PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

Route of Exposure

Symptoms

First Aid

Inhalation Fresh air rest.
Skin Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Diarrhoea. Headache. Nausea. Vomiting. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!).
Notes for ICSC Information
The possible contamination with compounds which might be carcinogenic means that special care should be taken to avoid exposure. Other melting points: 114C (technical grade). Depending on the degree of exposure periodic medical examination is indicated. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. The recommendations on this Card also apply to esters of dichlorprop. Cornox RK Hedonal DP are trade names. This card applies only to the substance itself not to formulations. Formulations may be more hazardous to the environment than the pure substance.

Indicates high toxicity in the given toxicological category. Indicates no available weight-of-the-evidence summary assessment. For additional information on toxicity from scientific journals or registration documents, see the "Additional Resources for Toxicity " section of the chemical detail page.
1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.

Summary of Acute Toxicity for Organism Group

Sorry, no honeybee acute toxicity data available for this chemical. Try related chemicals.

Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
