FIRE Combustible.  NO open flames.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!   
Inhalation Cough. Dizziness. Headache.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Burning sensation. Redness. Skin burns.  Protective gloves. Protective clothing.  Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear safety goggles, 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. Abdominal pain. Nausea. Vomiting. Diarrhoea. Dizziness. Headache. Shock or collapse.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rest. Do NOT induce vomiting. Refer for medical attention .
