EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames, NO sparks and NO smoking.  Use foam, carbon dioxide, powder. 
EXPLOSION Above 98°C explosive vapour/air mixtures may be formed.  Above 98°C use a closed system, ventilation and explosion-proof electrical equipment.   
 
EXPOSURE      
Inhalation Dizziness. Headache. Nausea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Severe deep burns. Pain.  Wear safety goggles 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 Nausea. Vomiting. Dizziness. Drowsiness. Headache. Weakness.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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 short-term exposure
The substance is corrosive to the eyes. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
