NOTE! STRICT HYGIENE!

Route of Exposure

Symptoms

First Aid
Inhalation Ataxia. Cough. Diarrhoea. Dizziness. Drowsiness. Nausea. Sore throat. Vomiting. Weakness. Fresh air rest. Half-upright position. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. Pain. (See Inhalation). Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion (See Inhalation). Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
Notes for ICSC Information
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate spray by a doctor or a person authorized by him/her should be considered.

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.
2. The acute toxicity reported on this page is of the pure chemical ingredient only and may not reflect the acute toxicity of individual pesticide products. To view acute toxicity of individual products, click on 'View Products' link in the 'Chemical Identification' section above.
