  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with incompatible substances. See Chemical Dangers.  NO open flames.  NO contact with incompatible materials: See Chemical Dangers  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Drowsiness.  Use ventilation.  Fresh air, rest. Seek medical attention if you feel unwell. 
Skin MAY BE ABSORBED!  Protective gloves.  Wear protective gloves when administering first aid. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Vomiting. Drowsiness. Laboured breathing. Unconsciousness.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is severely irritating to the eyes. Ingestion could cause effects on the central nervous system. This may result in excitement and central nervous system depression. Exposure at high concentrations could cause respiratory failure, convulsions and unconsciousness. See Notes. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
MAK skin absorption (H) 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Use of alcoholic beverages enhances the harmful effect.
