  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use powder, alcohol-resistant foam, carbon dioxide.   

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

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 sand or inert absorbent. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

 

Transportation
UN Classification
 

STORAGE
Separated from acids, bases and oxidants. Cool. Dry. Keep in a well-ventilated room. 
PACKAGING
 
ETHYLENE CYANOHYDRIN ICSC: 1026
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS-TO-YELLOW LIQUID. 

Physical dangers
 

Chemical dangers
The substance may polymerize under the influence of organic bases. Decomposes on heating and on contact with acids, acid fumes and water. This produces highly toxic fumes including hydrogen cyanide. Reacts violently with strong oxidants.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes and skin. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of long-term or repeated exposure
 


Occupational exposure limits
 

ENVIRONMENT
 

NOTES
This substance is less hazardous than some other nitriles which easily form hydrogen cyanide in the body.
