	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with incompatible substances. See Chemical Dangers.	NO open flames. NO contact with incompatible materials: See Chemical Dangers	Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Drowsiness.	Use ventilation.	Fresh air, rest. Seek medical attention if you feel unwell.
Skin	MAY BE ABSORBED!	Protective gloves.	Wear protective gloves when administering first aid. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety goggles.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Vomiting. Drowsiness. Laboured breathing. Unconsciousness.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention .

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, by ingestion and through the skin. Effects of short-term exposure The substance is severely irritating to the eyes. Ingestion could cause effects on the central nervous system. This may result in excitement and central nervous system depression. Exposure at high concentrations could cause respiratory failure, convulsions and unconsciousness. See Notes.	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. Effects of long-term or repeated exposure
