TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion.  NO contact with flammables. NO contact with organic materials, powdered metals, ammonium salts or reducing agents.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION See Chemical Dangers. Risk of fire and explosion.  Do NOT expose to friction or shock. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.  In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. 
 
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.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles 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. Blue lips, fingernails and skin. Confusion. Convulsions. Diarrhoea. Dizziness. Headache. Nausea. Unconsciousness. Vomiting. Weakness.  Do not eat, drink, or smoke during work.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Consult an expert! Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. 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.

Physical dangers
 

Chemical dangers
Mixtures with organic compounds, reducing agents, ammonia-containing agents and metal powders are shock-sensitive. Decomposes violently on heating. This produces oxygen and toxic fumes. This generates fire and explosion hazard. The substance is a strong oxidant. It reacts with combustible and reducing materials. 

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 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 blood and nervous system. This may result in formation of methaemoglobin. Exposure could cause hypokalaemia. This may result in cardiac disorders and muscular disorders. The effects may be delayed. Medical observation is indicated. Exposure could cause death. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 250°C
Density: 3.2 g/cm³
Solubility in water, g/100ml: 27.4 (good) 
The substance is harmful to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of paralysis do not become manifest until some hours have passed.
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.
10294-38-9 is a CAS registry number for Barium chlorate, monohydrate.
Will turn shock-sensitive if contaminated with: see Chemical Dangers.
Card has been partly updated in October 2004 and 2005.
