NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

Inhalation
Local exhaust or breathing protection.
Fresh air, rest.
Skin
Protective gloves.
Rinse skin with plenty of water or shower.
Eyes
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

LINURON ICSC: 1300
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS

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

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 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood, resulting in anaemia.
PHYSICAL PROPERTIES
Melting point: 93-94C
Solubility in water: none (< 0.1g/100ml)
Vapour pressure, Pa at 24C: 0.002
Octanol/water partition coefficient as log Pow: 3.2
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to algae and aquatic plants. 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
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. Afalon, Garnitan, Linex, Linorox, Linurex, Lorex, Sarclex, and Scarclex are trade names.
