International Chemical Safety Cards PLATINUM TETRACHLORIDE ICSC: 1145 Platinum (IV) chloride PtCl4 Molecular mass: 336.9 ICSC #    1145 CAS #     13454-96-1 RTECS # TP2275500 April 08, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Personal protection: P3 filter respirator for toxic particles. Separated from strong oxidants.

International Chemical Safety Cards PLATINUM TETRACHLORIDE ICSC: 1145 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: RED BROWN POWDER OR CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic fumes (chlorine). Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Pt) 0.002 mg/m³ as TWA; (ACGIH 2004). MAK: IIb (not established but data is available); sensitization of respiratory tract and skin (Sah); (DFG 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of dust and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes , the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point (decomposes): 370°C Relative density (water = 1): 4.3 Solubility in water, g/100 ml at 25°C: 58.7 ENVIRONMENTAL DATA N O T E S Card has been partly updated in April 2005.
