IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALS OR POWDER.

Chemical dangers
The substance decomposes on burning producing toxic fumes. Reacts with strong oxidants and acids.

Occupational exposure limits
TLV: (as Ba) 0.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: (as Ba) (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 the serum potassium level, on the muscles, heart and nervous system, resulting in muscle paralysis, cardiac dysrythmia and respiratory failure. Exposure (ingestion of high doses) may result in death.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Density: 2.47 g/cm³ Solubility in water, g/100 ml 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. See section Occupational Exposure Limits.
