IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS OR POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes. Reacts with strong oxidants and acids. 

Occupational exposure limits
TLV (as Ba): 0.5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK (inhalable fraction): 0.5 mg/m³; Peak limitation category: II(2); (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance may cause effects on the gastrointestinal tract and, by lowering serum potassium level, on muscles, heart and nervous system. This may result in muscle paralysis, cardiac dysrhythmia and respiratory failure. Ingestion could cause death. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Density: 2.47 g/cm³
Solubility in water, g/100ml at 20°C: 59   		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.
Card has been partly updated in October 2005.
