  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION 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.   

 PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 CLASSIFICATION & 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.

PHYSICAL & CHEMICAL INFORMATION

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.

Molecular mass: 45.0
Decomposes at 210°C
Melting point: 2.5°C
Relative density (water = 1): 1.13
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
Solubility in water: miscible
Vapour pressure, Pa at 20°C: 8
Relative vapour density (air = 1): 1.6
Flash point: 120°C c.c.
Auto-ignition temperature: >500°C
Octanol/water partition coefficient as log Pow: -1.51
Explosive limits, vol% in air: 2.7 - 19 


EXPOSURE & HEALTH EFFECTS

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

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. 

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


Occupational exposure limits
TLV: 10 ppm as TWA; (skin).
MAK skin absorption (H)
