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, foam, powder, carbon dioxide. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Confusion. Convulsions. Dizziness. Headache. Laboured breathing. Nausea. Vomiting. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer 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. Refer for medical attention . 
Eyes Redness. Blurred vision. Severe deep burns.  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. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give one or two glasses of water to drink. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT wash away into sewer. 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.  Do not transport with food and feedstuffs.

IMPORTANT DATA
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. 

Occupational exposure limits
TLV: 2ppm as TWA; (skin); (ACGIH 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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. Exposure could cause convulsions, unconsciousness and death. Medical observation is indicated. 

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.
