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. See Chemical Dangers.  Use water spray, alcohol-resistant foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!   
Inhalation Drowsiness. Headache. Nausea. Diarrhoea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear face shield.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent. Store and dispose of according to local regulations.

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H2; F1; R0.  Separated from oxidants, acids and bases. Dry. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS HYGROSCOPIC VISCOUS LIQUID. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes at 180°C. This produces toxic and corrosive gases including ammonia and hydrogen cyanide. Reacts with oxidants, acids and bases. This generates fire and toxic hazard. Attacks aluminium, brass, copper, iron, lead and some forms of plastic. 

Occupational exposure limits
TLV: 10ppm as TWA; (skin); (ACGIH 2011).
MAK (not established):. 

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 moderately irritating to the eyes and skin. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
May cause toxicity to human reproduction or development.
