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.
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.

PHYSICAL STATE; APPEARANCE:
WHITE OR GREY TO WHITE POWDER.

PHYSICAL DANGERS:

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
