Safety information
DOT Label：
Oxidizer Poison
First Aid：
Swallow: Medical attention immediately - If this chemical has been swallowed, get medical attention immediately.
Treatment：
Intravenous infusion of potassium often relieves many of the symptoms of barium toxicity. Methemoglobinemia can be treated with supplemental oxygen and methylene blue 1% solution administered intravenously slowly over five minutes followed by IV flush with normal saline. Methylene blue restores the iron in hemoglobin to its normal (reduced) oxygen-carrying state. (L1613, L214)
Fire Hazards：
Not combustible but enhances combustion of other substances. Risk of fire and explosion on contact with combustible substances or reducing agents.
Safe Storage：
Separated from combustible substances, reducing agents, powdered metals and food and feedstuffs. Store in an area without drain or sewer access.
Fire Fighting：
In case of fire in the surroundings, use appropriate extinguishing media. NO carbon dioxide.
Target Organs：
Eyes, skin, respiratory system, heart, central nervous system
Toxicity Data：
LD50: 355 mg/kg (Oral, Rat) (T26)
Eye Prevention：
Wear safety goggles.
Fire Potential：
Not combustible but enhances combustion of other substances.
Health Effects：
The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea, paralysisand possibly death. Barium may also cause gastrointestinal disturbances, damage the kidneys and cause decreases in body weight. Nitrate and nitrite poisoning causes methemoglobinemia. Nitrites may cause pregnancy complications and developmental effects. They may also be carcinogenic. (L1137, L214)
Health Hazards：
ERG2024, Guide 141 (Barium nitrate): · Runoff from fire control or dilution water may cause environmental contamination.
Reactive Group：
Nitrate and Nitrite Compounds, Inorganic
Adverse Effects：
Methemoglobinemia - The presence of increased methemoglobin in the blood; the compound is classified as secondary toxic effect
Exposure Routes：
Oral (L214); inhalation (L214)
Fire Prevention：
NO contact with flammables.
Hazards Summary：
A skin, eye, nose, and throat irritant; A skin, eye, and respiratory tract irritant; Exposure could cause hypokalemia, resulting in cardiac disorders and muscular disorders. Exposure may result in death. [ICSC] An irritant; [MSDSonline] See Barium. See NITRATES and NITRITES.
Inhalation Risk：
Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Skin Prevention：
Protective gloves.
DOT ID and Guide：
1446 141
Disposal Methods：
Package lots. Place in a separate labeled container for recycling or disposal. Small quantities. Wear nitrile rubber gloves, laboratory coat, and eye protection. Avoid breathing dust. Dissolve the barium salt in the minimum volume of water. For each gram of barium salt, add 15 mL of 10% sodium sulfate solution. Let stand for 1 week. Test for completeness of precipitation by adding a few drops of 10% sodium sulfate solution. If required, add more sodium sulfate solution until no further precipitation occurs. Decant supernatant liquid or filter solid. Treat solid as normal refuse. Wash liquid into drain. /Barium salt/
Flammable Limits：
Flammability: Noncombustible Solid, but will accelerate the burning of combustible materials.
Toxicity Summary：
Barium is a competitive potassium channel antagonist that blocks the passive efflux of intracellular potassium, resulting in a shift of potassium from extracellular to intracellular compartments. The intracellular translocation of potassium results in a decreased resting membrane potential, making the muscle fibers electrically unexcitable and causing paralysis. Some of these barium's effects may also be due to barium induced neuromuscular blockade and membrane depolarization. Nitrate's toxicity is a result of it's conversion to nitrite once in the body. Nitrite causes the autocatalytic oxidation of oxyhemoglobin to hydrogen peroxide and methemoglobin. This elevation of methemoglobin levels is a condition known as methemoglobinemia, and is characterized by tissue hypoxia, as methemoglob...
EC Classification：

Reactivity Profile：
Mixtures of metal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures of nitrates with phosphorus, tin(II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109].
Signs and Symptoms：
Ingesting excess barium may cause vomiting, abdominal cramps, diarrhea, difficulties in breathing, increased or decreased blood pressure, numbness around the face, and muscle weakness. High levels may result in changes in heart rhythm or paralysis and possibly death. Nitrate and nitrite poisoning causes methemoglobinemia. Symptoms include cyanosis, cardiac dysrhythmias and circulatory failure, and progressive central nervous system (CNS) effects. CNS effects can range from mild dizziness and lethargy to coma and convulsions. (L1137, L214)
