IMPORTANT DATA
Physical State; Appearance WHITE CRYSTALLINE POWDER. Chemical dangers Reacts violently with strong acids. Reacts violently with bromotrifluoride causing fire hazard. Occupational exposure limits TLV not established. MAK not established.	Routes of exposure The substance can be absorbed into the body by ingestion. Inhalation risk A harmful concentration of airborne particles can be reached quickly especially if powdered Effects of short-term exposure May cause mechanical irritation. Exposure could cause hypokalaemia, resulting in muscular and cardiac disorders if ingested in large doses.
