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.

CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion .

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes , is irritating to the skin and the respiratory tract . The substance may cause effects on the nervous system .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.

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.
