| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: WHITE OR GREY TO WHITE POWDER. CHEMICAL DANGERS: The substance decomposes on heating and on contact with wateror 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: TLV: (as Ba) 0.5 mg/m³ as TWA A4 (not classifiable as a human carcinogen); (ACGIH 2005). MAK: 0.5 mg/m³ (Inhalable fraction) Peak limitation category: II(2) (DFG 2005). |
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 nervous system. Exposure could cause hypokalaemia , resulting in cardiac disorders and muscular disorders. | ||
| 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.
| |||
| NOTES | |||
|
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Rinse contaminated clothes (fire hazard) with plenty of water.
