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.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!   
Inhalation Drowsiness. Headache. Nausea. Unconciousness.  Use 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.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
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 containers as far as possible. Collect leaking liquid in sealable steel (not copper) containers. Wash away remainder with plenty of water.

GHS Classification
 

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

IMPORTANT DATA
Physical State; Appearance
COLOURLESS HYGROSCOPIC VISCOUS LIQUID. 

Physical dangers
No data. 

Chemical dangers
On combustion, forms toxic gases of nitrogen oxides. Decomposes at 180°C. This produces ammonia, water, carbon monoxide and hydrogen cyanide. Reacts with oxidants. Attacks metals such as aluminium, iron and copper. Attacks natural rubber. 

Occupational exposure limits
TLV: 10ppm 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 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.
