May react violently with bromine trifluoride. May result in explosion with potassium permanganate and sulfuric acid.
Chlorine, irritating and toxic fumes and gases, potassium fume.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Material will not burn. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use extinguishing media appropriate to the surrounding fire. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
These substances will accelerate burning when involved in a fire.
Flammability data is not available, but this compound is probably nonflammable.
Fire may produce irritating, corrosive and/or toxic gases.
Ingestion of large amounts may cause gastrointestinal irritation. May cause gastric disturbances and electrolytic imbalance.
Dust is irritating to the respiratory tract. Low hazard for usual industrial handling.
May cause skin irritation.
Dust may cause mechanical irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
