NOTE! PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
 General First Aid: IN ALL CASES CONSULT A DOCTOR!

Route of Exposure

Symptoms

First Aid
Inhalation Convulsions. Dizziness. Sweating. Laboured breathing. Nausea. Unconsciousness. Vomiting. Pupillary constriction muscle cramp excessive salivation. Symptoms may be delayed (see Notes). Fresh air rest. Refer for medical attention.
Skin MAY BE ABSORBED! (See Inhalation). Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain. Pupillary constriction. Blurred vision. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Abdominal cramps. Diarrhoea. Laboured breathing. Nausea. Unconsciousness. Vomiting. Weakness. Pupillary constriction muscle cramps excessive salivation. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.
Notes for ICSC Information
Depending on the degree of exposure periodic medical examination is indicated. The symptoms of acute intoxication do not become manifest until some hours have passed. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. The recommendations on this card apply to the pure form. Commercial formulations are often mixtures including impurities solvent or other agents which modify toxic and physicochemical properties. Acrol DEP DANEX DIMETOX are trade names.

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.

Any underlined term with a book icon has additional information.

* Data marked with an asterisk indicates that this chemical is not explicitly listed on the corresponding list. Instead, it belongs to a group of chemicals that IS designated on the list. For example, if an agency assigns a classification of reproductive toxicant to "mercury compounds", that classification is applied to all mercury compounds in the PAN Pesticide database, which are then marked with an asterisk.
