Types of Hazard/ Exposure	Acute Hazards/ Symptoms	Prevention	First Aid/ Fire Fighting
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, water spray, foam, carbon dioxide .
Explosion

Exposure		PREVENT DISPERSION OF DUST!
•Inhalation	Cough. Sore throat. Dizziness. Headache. Nausea.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
•Skin	Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
•Eyes	Redness. Pain.	Safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•Ingestion	Abdominal pain. Salivation. Nausea. Vomiting. Headache. Dizziness. Tremors. Weakness. Convulsions.	Do not eat, drink, or smoke during work. Wash hands before eating.	Give a slurry of activated charcoal in water to drink. Refer for medical attention.

Spillage Disposal

Storage

Packaging & Labelling

Environmental
Data

The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.

N O T E S

Carrier solvents used in commercial formulations may change physical and toxicological properties. If the substance is formulated with solvents also consult the ICSCs of these materials. Do NOT take working clothes home. The technical product is a brown to yellow liquid, with a melting point between 43-54°C and a boiling point between 151-167°C. See ICSC 0273 Fenvalerate. Card has been partly updated in April 2005. See section EU classification.
