NOTE! AVOID ALL CONTACT!
General First Aid: IN ALL CASES CONSULT A DOCTOR!

Route of Exposure

Symptoms

First Aid

Inhalation Abdominal cramps. Burning sensation. Cough. Headache. Laboured breathing. Nausea. Sore throat. Vomiting. Fresh air rest. Half-upright position. Refer for medical attention.
Skin MAY BE ABSORBED! Skin burns. Pain (Further see Inhalation). First rinse with plenty of water then remove contaminated clothes and rinse again. Refer for medical attention.
Eyes Pain. Blurred vision. Permanent loss of vision. Severe deep burns. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Convulsions (further see Inhalation). Rinse mouth. Rest. Refer for medical attention.
Notes for ICSC Information
Depending on the degree of exposure periodic medical examination is indicated. 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 are therefore essential. Immediate administration of an appropriate spray by a doctor or a person authorized by him/her should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Rinse contaminated clothes (fire hazard) with plenty of water. Aerozine-50 and Dimazine 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.

Terrestrial Ecotoxicity

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.
Honeybee Chronic Toxicity
