International Chemical Safety Cards FERROUS OXIDE ICSC: 0793 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: BLACK SOLID IN VARIOUS FORMS. CHEMICAL DANGERS: The substance may spontaneously ignite on contact with air when heated above 200°C. The substance is easily oxidized by air and readily absorbs carbon dioxide. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. MAK as respirable dust: ppm; 6 mg/m3; (1995). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the lungs , resulting in siderosis. PHYSICAL PROPERTIES Melting point: 1360°C Relative density (water = 1): 5.7 Solubility in water: none
