In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.  •SKIN Dry skin. Redness. Protective gloves. First rinse with plenty of water, then remove contaminated clothes and rinse again.  •EYES Safety goggles. 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. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place.

International Chemical Safety Cards CHROMOUS CHLORIDE ICSC: 1317 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: VERY HYGROSCOPIC SOLID IN VARIOUS FORMS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance is a strong reducing agent and reacts with oxidants. The substance may reduce the oxygen content of air in confined spaces. Reacts with water forming flammable/explosive gas (hydrogen - see ICSC0001) . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation 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 irritates the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 1300°C Melting point: 824°C Density: 2.8 g/cm3 Solubility in water: very good ENVIRONMENTAL DATA It is strongly advised not to let the chemical enter into the environment because it persists in the environment. N O T E S Health effects of exposure to the substance have not been investigated adequately. ADDITIONAL INFORMATION ICSC: 1317 CHROMOUS CHLORIDE (C) IPCS, CEC, 1994
