BARIUM NITRATE ICSC: 1480
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS OR CRYSTALLINE POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating producing nitrogen oxides. The substance is a strong oxidant and reacts with combustible and reducing materials. Reacts with powdered metals causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Barium, soluble) 0.5 mg/m as TWA; A4; (ACGIH 2004).
MAK: (inhalable fraction) 0.5 mg/m; Peak limitation category: II(2); (DFG 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. Exposure could cause hypokalaemia, resulting in cardiac disorders and muscular disorders. Exposure may result in death.

PHYSICAL PROPERTIES
Decomposes below boiling point
Melting point: 590C
Density: 3.24 g/cm
Solubility in water, g/100 ml at 20C: 8.7 moderate
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Temperature of decomposition unknown in literature. Rinse contaminated clothes (fire hazard) with plenty of water. Will turn shock-sensitive if contaminated with magnesium-aluminium alloys, sulfur powder or light metal powder. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
