EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nerve terminals of the skin. This may result in subjective facial skin sensation characterized by tingling, burning or numb sensation.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to bees. Avoid release to the environment in circumstances different to normal use.

NOTES
Cyhalothrin is a pyrethroid insecticide used in agriculture, also used in public and animal health. Carrier solvents used in commercial formulations may change physical and toxicological properties. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). See ICSC 0859.
