  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances.  Risk of fire and explosion on contact with combustible substances or reducing agents.  NO contact with flammables.    In case of fire in the surroundings, use appropriate extinguishing media. NO carbon dioxide.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Shortness of breath. Sore throat. See Ingestion.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Excessive salivation. Abdominal cramps. Abdominal pain. Diarrhoea. Nausea. Vomiting. Shortness of breath. Weakness.  Do not eat, drink, or smoke during work.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). See Notes. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Then wash away with plenty of water. Do NOT let this chemical enter the environment. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.

BARIUM NITRATE ICSC: 1480
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS-TO-WHITE CRYSTALS OR CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces nitrogen oxides. The substance is a strong oxidant. It reacts with combustible and reducing materials. Reacts with powdered metals. This generates fire and explosion hazard. 

Formula: BaN2O6 / Ba(NO3)2
Molecular mass: 261.4
Decomposes
Melting point: 590°C
Density: 3.24 g/cm³
Solubility in water, g/100ml at 20°C: 8.7 (moderate) 


EXPOSURE & HEALTH EFFECTS

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

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

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 long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
EU-OEL: (as Ba): 0.5 mg/m3 as TWA 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Temperature of decomposition is unknown in the literature.
Rinse contaminated clothing with plenty of water because of fire hazard.
Will turn shock-sensitive if contaminated with magnesium-aluminium alloys, sulfur powder and light metal powder.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
