TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Alcohol-resistant foam, dry sand, powder, carbon dioxide, NO water.
EXPLOSION

EXPOSURE		PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
Inhalation	Burning sensation. Cough. Sore throat.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest.
Skin	Facial skin sensations. Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety goggles, or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

CYHALOTHRIN

ICSC: 0858

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
YELLOW-BROWN VISCOUS LIQUID (TECHNICAL GRADE), WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating above 275°C producing toxic fumes. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV 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.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the nerve terminals of the skin, resulting in subjective facial skin sensation characterized by tingling, burning or numb sensation.

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

PHYSICAL PROPERTIES

Decomposes below boiling point at 275°C
Melting point: <10°C
Relative density (water = 1): 1.2
Solubility in water: none
Vapour pressure, Pa at 20°C: <0.001

Flash point: <80°C
Octanol/water partition coefficient as log Pow: 6.9

ENVIRONMENTAL DATA

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to honey 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. 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. Grenade is a trade name. Also consult ICSC # 0859 lambda-Cyhalothrin.
