  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, foam, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Headache. Vomiting. Dizziness. Nausea. Laboured breathing. Confusion. Convulsions.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Administration of oxygen may be needed. No mouth-to-mouth artificial respiration. Refer immediately for medical attention. See Notes. 
Skin MAY BE ABSORBED! Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Administration of oxygen may be needed. Refer immediately for medical attention. See Notes. 
Eyes Redness. Blurred vision.  Wear face shield.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Abdominal pain. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Administration of oxygen may be needed. Give one or two glasses of water to drink. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. 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.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
ODOURLESS OILY COLOURLESS LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces highly toxic hydrogen cyanide (see ICSC 0492). Reacts violently with strong oxidants. Reacts with strong acids, strong bases and reducing agents. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes and skin. Exposure could cause convulsions, unconsciousness and death. Medical observation is indicated. 

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
The substance may have effects on the blood and adrenals. This may result in anaemia and tissue lesions. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 2 ppm as TWA; (skin)
