TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Use alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION	Risk of explosion on contact with strong oxidants.

EXPOSURE		PREVENT GENERATION OF MISTS!
Inhalation	Cough. Sore throat. Further see Ingestion.	Avoid inhalation of mist.	Fresh air, rest. Refer for medical attention.
Skin	See Ingestion.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety goggles.	Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
Ingestion	Cough. Sore throat. Headache. Dizziness. Drowsiness.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Refer immediately for medical attention.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS-TO-PALE-YELLOW HYGROSCOPIC LIQUID.

Physical dangers
No data.

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including hydrogen chloride (see ICSC 0163). Reacts with strong oxidants. This generates fire and explosion hazard.

Occupational exposure limits
TLV not established.
MAK (2b (not established but data is available)): (DFG 2008).

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system.

Effects of long-term or repeated exposure
The substance may have effects on the kidneys. This may result in kidney impairment. Tumours have been detected in experimental animals but may not be relevant to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
