TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/SYMPTOMS PREVENTION FIRST AID/FIRE FIGHTING FIRE Not combustible but enhances combustion of other substances. NO contact with combustibles reducing agents and acid(s). In case of fire in the surroundings: all extinguishing agents allowed.
contact with combustible substances and reducing agents. EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! Inhalation Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat (see Ingestion). Local exhaust or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
Redness. Skin burns. Pain. Protective gloves. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again.
Redness. Pain. Blurred vision. Safety goggles, or face shield, or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Abdominal pain. Vomiting. Diarrhoea. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL PACKAGING & LABELLING Sweep spilled substance into containers, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. (Extra personal protection: P2 filter respirator for harmful particles). O Symbol Xn Symbol R: 8-20/22 S: (2-)13-27 UN Hazard Class: 5.1 UN Subsidiary Risks: 6.1 UN Pack Group: II Do not transport with food and feedstuffs.
Transport Emergency Card: TEC (R)-51G12 NFPA Code: H1; F0; R0; ox Separated from combustible and reducing substances, food and feedstuffs. Dry.
Decomposes below boiling point at 800°C Melting point: 450°C Relative density (water = 1): 5.0 Solubility in water: poor LEGAL NOTICE Neither the EC nor the IPCS nor any person acting on behalf of the EC or the IPCS is responsible for the use which might be made of this information ©IPCS 2000 0381 BARIUM PEROXIDE IMPORTANT DATA Physical State; Appearance WHITE OR GREY TO WHITE POWDER. Chemical dangers The substance decomposes on heating and on contact with water or acids producing oxygen and hydrogen peroxide, which increases fire hazard. The substance is a strong oxidant and reacts violently with combustible and reducing materials.
TLV (as Ba): 0.5 mg/m 3 (TWA) (ACGIH 1999). Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
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.
The substance is harmful to aquatic organisms. NOTES Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Rinse contaminated clothes (fire hazard) with plenty of water.

4 Molecular mass: 233.43 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: all extinguishing agents allowed.
Local exhaust or breathing protection. Fresh air, rest. Skin Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.
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. SPILLAGE DISPOSAL PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. (Extra personal protection: P1 filter respirator for inert particles).
