  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use water spray, alcohol-resistant foam, dry powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Rinse skin with plenty of water or shower. Rinse skin with plenty of water or shower. 
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Diarrhoea.  Do not eat, drink, or smoke during work.  Rinse mouth. Rinse mouth. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Ventilation. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
HYGROSCOPIC VISCOUS COLOURLESS LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces corrosive fumes of acrolein. Reacts with strong oxidants. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

Effects of short-term exposure
 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
MAK: (inhalable fraction): 200 mg/m3; peak limitation category: I(2); pregnancy risk group: C
