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.
EXPLOSION Risk of fire and explosion on 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.
  • SKIN
    		• Redness. Skin burns. Pain.
    		Protective gloves. Protective clothing.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again.
  • EYES
    		• 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.
  • INGESTION
    		• Sore throat. Abdominal pain. Vomiting. Diarrhoea.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE 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).
    		Separated from combustible and reducing substances, food and feedstuffs. Dry.
    		Do not transport with food and feedstuffs.

    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.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (Barium and soluble compounds, as Ba): 0.5 mg/m3 A4 (TWA) (ACGIH 1996).


    		 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 cardiovascular system, nervous system , resulting in cardiac disorders.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Decomposes below boiling point at 800░C
    Melting point: 450░C
    		 Relative density (water = 1): 5.0
    Solubility in water: poor
    ENVIRONMENTAL
    DATA
         		The substance is harmful to aquatic organisms.
    N O T E S
    Depending on the degree of exposure, periodic medical examination is indicated. Rinse contaminated clothes (fire hazard) with plenty of water. Also consult ICSC # 0164 (hydrogen peroxide).
