Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Cough. Sore throat. (See Ingestion). Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety spectacles, 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 cramps. Convulsions. Dullness. Unconsciousness. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. 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. (Extra personal protection: P2 filter respirator for harmful particles). Separated from food and feedstuffs . Do not transport with food and feedstuffs.

International Chemical Safety Cards BARIUM CHLORIDE ICSC: 0614 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS , COLOURLESS CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Ba) 0.5 mg/m³ (ACGIH 1999). OSHA PEL*: TWA 0.5 mg/m3 *Note: The PEL also applies to other soluble barium compounds (as Ba) NIOSH REL: TWA 0.5 mg/m3 *Note: The REL also applies to other soluble barium compounds (as Ba) except Barium sulfate. NIOSH IDLH: 50 mg/m3 (as Ba) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol 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 eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system . Exposure could cause hypokalaemia , resulting in cardiac disorders and muscular disorders. Exposure may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 1560°C Melting point: 960°C Density: 3.9 g/cm3 Solubility in water, g/100 ml: 36 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
