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, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE See Notes.  PREVENT GENERATION OF MISTS!   
Inhalation Cough.  Avoid inhalation of mist. Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Seek medical attention if you feel unwell. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Cough.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Seek medical attention if you feel unwell.

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces irritating fumes. 

Occupational exposure limits
TLV: 0.5ppm as TWA; (ACGIH 2011).
MAK (not established):. 

Routes of exposure
 

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. 

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

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking.
