ROUTES OF EXPOSURE: The substance can be absorbed into the body by ingestion . INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed, especially, if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes and the respiratory tract . The substance may cause effects on the cardiovascular system , resulting in cardiac dysrhythmia when ingested at high amounts. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Sublimation point: 1500°C Melting point: 770-773°C Density: 1.98 g/cm3 Solubility in water, g/100 ml at 20°C: good ENVIRONMENTAL DATA N O T E S ADDITIONAL INFORMATION ICSC: 1450 POTASSIUM CHLORIDE (C) IPCS, CEC, 1994
