International Chemical Safety Cards TIN (II) CHLORIDE DIHYDRATE ICSC: 0738 Stannous chloride dihydrate SnCl2• 2H2O Molecular mass: 225.6 ICSC #    0738 CAS #     10025-69-1 RTECS # XP8850000 UN #        3260 April 22, 2004 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  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety goggles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Diarrhoea. Nausea. Vomiting. Do not eat, drink, or smoke during work. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Personal protection: P2 filter respirator for harmful particles. Separated from strong oxidants. Keep in a well-ventilated room.

International Chemical Safety Cards TIN (II) CHLORIDE DIHYDRATE ICSC: 0738 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO WHITE SOLID IN VARIOUS FORMS PHYSICAL DANGERS: CHEMICAL DANGERS: Upon heating, toxic fumes are formed. The substance is a strong reducing agent and reacts violently with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Sn, oxide and inorganic compounds, except tin hydride) 2 mg/m³ as TWA; (ACGIH 2004). EU OEL: (tin inorganic compounds, as Sn) 2 mg/m³ as TWA; (EU 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: A harmful concentration of airborne particles can be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Decomposes below boiling point at 652°C Melting point: 38°C Density: 2.71 g/cm3 Solubility in water: very good (>100 g/100 ml at 20°C) ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S The apparent melting point caused by loss of crystal water is given. Stannochlor is a trade name.
