EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use powder, carbon dioxide, foam. 
EXPLOSION Above 80°C explosive vapour/air mixtures may be formed.  Above 80°C use a closed system and ventilation.   
 
EXPOSURE   PREVENT GENERATION OF MISTS!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Redness. Pain. Burning sensation. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear face shield 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 in the throat and chest. Abdominal pain. Shock or collapse.  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 .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Reacts violently with strong oxidants, bases, acid anhydrides and acid chlorides. Attacks copper and its alloys. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. 

Effects of short-term exposure
The substance is corrosive to the skin and eyes. The vapour is irritating to the respiratory tract. Corrosive on ingestion. 

Effects of long-term or repeated exposure
