Fire Fighting Media and Instructions N/A
Special Remarks on Fire Hazards Powerful oxidizing agent; may ignite oxidizable materials. Contact with combustible or organic materials may cause fire. A mixture of sulfur and barium chlorate ignites at about 108-111 C. Contact with strong sulfuric acid can cause fires or explosions. When mixed with ammonium salts, spontaneous decomposition and ignition may result.
Special Remarks on Explosion Hazards A combination of finely divided aluminum, arsenic, carbon, copper, metal sulfides, organic matter,
phosphorus, or sulfur with finely divided chlorates of barium can be exploded by heat, percussion, and
sometimes light friction.
Contact with strong sulfuric acid can cause fires or explosions.
Mixtures of finely divided combustible materials (such as certain dusty forms of floor sweepings/saw dust),
charcoal with chlorates can explode virtually spontaneously.
Chlorates can also present a dangerous explosion hazard when shocked, exposed to heat, or rubbed,
particularly when contaminated with As2S3, CaH2, Hg3P4, Manganese dioxide, NaH2PO2, PHI4, SCN,
ammonium compounds, cyanides, metals + acids, organic acids, phosphorus or antimony sulfide, selenium,
shellac, starch, sugar.


Small Spill Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill Oxidizing material. Organic peroxide.
Stop leak if without risk. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep
substance damp using water spray. Do not use metal tools or equipment. Do not touch spilled material. Use
water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Call
for assistance on disposal. Be careful that the product is not present at a concentration level above TLV.
Check TLV on the MSDS and with local authorities.


Precautions Keep away from heat. Keep away from sources of ignition. Keep away from combustible material.. Do not ingest. Do not breathe dust. Wear suitable protective clothing. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from incompatibles such as reducing agents, combustible materials, organic materials, metals, acids.
Storage Keep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies, reducing agents and combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers.


Engineering Controls Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep
exposure to airborne contaminants below the exposure limit.
Personal Protection Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.

See more Barium products. Barium (atomic symbol: Ba, atomic number: 56) is a Block S, Group 2, Period 6 element with an atomic weight of 137.27. The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s2. Barium Bohr ModelBarium is a member of the alkaline-earth metals. The barium atom has a radius of 222 pm and a Van der Waals radius of 268 pm. Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808. Elemental BariumIn its elemental form, barium is a soft, silvery-gray metal. Industrial applications for barium include acting as a "getter," or unwanted gas remover, for vacuum tubes, and as an additive to steel and cast iron. Barium is also alloyed with silicon and aluminum in load-bearing alloys. The main commercial source of barium is the mineral barite (BaSO4); it does not occur naturally as a free element . The name barium is derived from the Greek word "barys," meaning heavy.


Chlorine is a Block P, Group 17, Period 3 element. Its electron configuration is [Ne]3s23p5. The chlorine atom has a covalent radius of 102±4 pm and its Van der Waals radius is 175 pm. Chlorine ModelIn its elemental form, chlorine is a yellow-green gas. Chlorine is the second lightest halogen after fluorine. It has the third highest electronegativity and the highest electron affinity of all elements, making it a strong oxidizing agent. It is rarely found by itself in nature. Chlorine was discovered and first isolated by Carl Wilhelm Scheele in 1774. It was first recognized as an element by Humphry Davy in 1808.
