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.  Use 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.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Numbness. Tingling sensation. Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in lime, damp sawdust, sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
YELLOW-BROWN VISCOUS (TECHNICAL-GRADE PRODUCT) LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes above 275°C . This produces 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 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. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA

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.
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.
