TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!
Inhalation	Drowsiness. Headache. Nausea. Unconsciousness.	Ventilation.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness.	Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness.	Face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. (See Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Rest. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable steel (not copper) containers as far as possible. Wash away spilled liquid with plenty of water.	T Symbol R: 61 S: 53-45

EMERGENCY RESPONSE	SAFE STORAGE
NFPA Code: H2; F1; R	Separated from oxidants. Dry.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS, HYGROSCOPIC, VISCOUS LIQUID.

Chemical dangers
On combustion, forms toxic gases (nitrogen oxides). The substance decomposes on heating at 180°C producing ammonia, water, carbon monoxide and hydrogen cyanide. Reacts with oxidants. Attacks metals such as aluminium, iron, copper and natural rubber.

Occupational exposure limits
TLV: 10 ppm as TWA; (skin); (ACGIH 2004).

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

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

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

Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes toxic effects upon human reproduction.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point (decomposes): 210°C Melting point: 2.5°C Relative density (water = 1): 1.13 Solubility in water: very good Vapour pressure, Pa at 20°C: about 2 Relative vapour density (air = 1): 1.6 Flash point: 154°C o.c. Auto-ignition temperature: >500°C

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
