EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use foam, dry powder, carbon dioxide. 
EXPLOSION Above 77°C explosive vapour/air mixtures may be formed.  Above 77°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  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. Do NOT induce vomiting.

Physical dangers
 

Chemical dangers
Reacts with strong oxidants, halogens and inorganic acids. Attacks rubber, paints and lining materials. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

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; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
If swallowed the substance easily enters the airways and could result in aspiration pneumonitis. 

Effects of long-term or repeated exposure
The liquid defats the skin.
