NOTE! PREVENT DISPERSION OF DUST! STRICT HYGIENE!
General First Aid: IN ALL CASES CONSULT A DOCTOR!

Route of Exposure

Symptoms

First Aid

Inhalation Burning sensation. Convulsions. Cough. Laboured breathing. Shortness of breath. Sore throat. Fresh air rest.
Skin Redness. Pain. Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Abdominal pain. Cough. Do NOT induce vomiting. Refer for medical attention.
Notes for ICSC Information
Liquid formulation can be aspired into the lungs resulting in chemical pneumonitis showing tremors and convultions. 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. Do NOT take working clothes home. The recommendations on this Card also apply to cyhalothrin. Karate Charge Commodore Excalibur Hallmark Icon Matador PP 321 Saber and Sentinel are trade names.

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.

Organism Group Average Acute Toxicity Acute Toxicity Range
HoneybeesHighly ToxicHighly Toxic
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.
