International Chemical Safety Cards TITANIUM CARBIDE ICSC: 1319 TiC Molecular mass: 59.9 ICSC #    1319 CAS #     12070-08-5 RTECS # November 26, 1998 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Rinse skin with plenty of water or shower.  •EYES Safety spectacles, or eye protection in combination with breathing protection if powder.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles). R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 1319 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards TITANIUM CARBIDE ICSC: 1319 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: GREY CRYSTALLINE POWDER. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on contact with sparks , causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. 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. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure to dust particles. PHYSICAL PROPERTIES Boiling point: 4820°C Melting point: 3140°C Density: 4.9 g/cm3 Solubility in water: none ENVIRONMENTAL DATA N O T E S Health effects of exposure to the substance have not been investigated adequately. The substance is usually used in combination with other compounds such as tungsten carbide, cobalt. Workers exposed to mixed dusts containing titanium carbide have developed pneumoconiosis.
