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.	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.
Ingestion		Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Rest. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: self-contained breathing apparatus.	Xn Symbol N Symbol R: 22-40-48/22-50/53 S: (2-)36/37-60-61	Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	SAFE STORAGE
	Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs.

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 20°C 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	ENVIRONMENTAL DATA
Melting point: 93-94°C Solubility in water: none (< 0.1g/100ml) Vapour pressure, Pa at 24°C: 0.002 Octanol/water partition coefficient as log Pow: 3.2	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.
