LAMBDA-CYHALOTHRIN ICSC: 0859
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO BEIGE SOLID (TECHNICAL GRADE).

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides hydrogen chloride and hydrogen fluoride.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of fine dust and mist and by ingestion.

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

PHYSICAL PROPERTIES
Decomposes below boiling point at 275C
Melting point: 49.2C
Relative density (water = 1): 1.3
Solubility in water: none
Vapour pressure, Pa at 20C: <0.001
Octanol/water partition coefficient as log Pow: 7.0
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. The substance may be hazardous to the environment; special attention should be given to mammals and honey bees. The substance may cause long-term effects in the aquatic environment. 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.
NOTES
Liquid formulation can be aspired into the lungs resulting in chemical pneumonitis, showing tremors and convultions. 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. Do NOT take working clothes home. The recommendations on this Card also apply to cyhalothrin. Karate, Charge, Commodore, Excalibur, Hallmark, Icon, Matador, PP 321, Saber, and Sentinel are trade names.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
