TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Cough. Sore throat. See Ingestion.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea. Diarrhoea. Vomiting. Weakness. Dullness. Unconsciousness.  Do not eat, drink, or smoke during work.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
WHITE SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes. 

Occupational exposure limits
TLV (as Ba): 0.5mg/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(8); Pregnancy risk group: D; BAR issued; (DFG 2009). 

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, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system. Exposure could cause hypokalaemia. This may result in cardiac disorders and muscular disorders. Exposure could cause death. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 113°C
See Notes.
Density: 3.86 g/cm³
Solubility in water, g/100ml at 26°C: 37.5 (good) 
The substance is harmful to aquatic organisms. 

NOTES
The apparent melting point caused by loss of crystal water is given.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
