HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Sore throat. Headache. Confusion. Weakness. Shortness of breath. Convulsions. Unconciousness. See Notes.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. No mouth-to-mouth artificial respiration. Administration of oxygen may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain. See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  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. Nausea. Vomiting. Diarrhoea. See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Wear protective gloves when inducing vomiting. Give a slurry of activated charcoal in water to drink. NO mouth-to-mouth artificial respiration. Administration of oxygen may be needed. Refer for medical attention . See Notes.
