EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use powder, carbon dioxide, foam. 
EXPLOSION Above 82°C explosive vapour/air mixtures may be formed.  Above 82°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation Cough. Dizziness. Lethargy. Headache. Nausea. Sore throat.  Use ventilation.  Fresh air, rest. Artificial respiration may be needed. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
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 Diarrhoea. Vomiting. Further see Inhalation.    Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. 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 dangers
 

Chemical dangers
Reacts with strong oxidants. 

Occupational exposure limits
TLV: 50ppm as TWA; (skin); (ACGIH 1999). 

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, skin and respiratory tract. The substance may cause effects on the central nervous system. 

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