International Chemical Safety Cards SODIUM ALUMINATE ICSC: 0566 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE , HYGROSCOPIC POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: The solution in water is a strong base, it reacts violently with acid and is corrosive to aluminium, tin and zinc. Reacts with ammonium salts causing fire hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV (as Al (soluble salts)): 2 mg/m3 (as TWA) (ACGIH 1999). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed . EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: 1650°C Density: >1.5 g/cm3 Solubility in water: very good ENVIRONMENTAL DATA N O T E S Other UN numbers: 1819 (sodium aluminate, 80% solution): hazard class: 8, pack group: III. Other CAS number: 11138-49-1. Transport Emergency Card: TEC (R)-80G09 ADDITIONAL INFORMATION ICSC: 0566 SODIUM ALUMINATE (C) IPCS, CEC, 1994
