  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 70°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 70°C use a closed system and ventilation.  Use alcohol-resistant foam. Use dry powder. Use carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
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 Burning sensation. Headache. Dizziness. Nausea. Drowsiness.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes and respiratory tract. The substance is mildly irritating to the skin. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure at high levels could cause effects on the central nervous system. 

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is harmful to aquatic organisms.
