Barium permananganate is a brownish-violet, dark purple to black crystalline solid.

As dry cell depolarizer.

A purplish colored crystalline solid. Noncombustible, but accelerates burning of combustible material. Finely divided combustible materials may be explosive. May spontaneously ignite on contact with combustible liquids. Contact with sulfuric acid may result in fires or explosions. Used as a disinfectant and to make other permanganates.

Soluble in water.

Acetic acid or acetic anhydride can explode with permanganates, such as Barium permanganate, if not kept cold [Von Schwartz 1918 p 34 ]. Explosions can occur when permanganates that have been treated with sulfuric acid come in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or organic matter.

Inhalation or contact with eyes or skin causes irritation. Ingestion causes abdominal pain, nausea, vomiting, pallor, shortness of breath.

Behavior in Fire: Can increase the intensity of fire.

Oxidizing material. Fire and explosion risk in contact with organic materials. Toxic by ingestion.

It is used to make dry cells and other permanganates, and as a disinfectant.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

UN1448 Barium permanganate, Hazard Class: 5.1; Labels: 5.1—Oxidizer, 6.1—Poisonous materials.

A strong oxidizer. May be explosive on contact with combustible and finely divided materials/ metals. Keep away from sulfuric acid; possibly explosive. Explosions can occur when permanganates that have been treated with sulfuric acid come in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or organic matter. Contact with acetic acid or acetic anhydride can cause explosion. if not kept cold . Incompatible with acetic acid, acetic anhydride, and organic or combustible materials (such as wood, paper, oil, and fuels), since violent reactions can occur. When mixed with combustible materials, this material can ignite by friction or acids; may be spontaneously combustible.

Barium permanganate is a brownish-violet,dark purple to black crystalline solid. Molecular weight =375.2; Specific gravity (H2O:1)=3.77 at 20℃. HazardIdentification (based on NFPA-704 M Rating System):Health 2, Flammability 0, Reactivity 0. Soluble inwater.

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number N450, must conform with USEP A regulations for storage, transportation, treatment, and disposal of waste. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Dispose of contents and container to an approved waste disposal plant. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. All federal, state, and local environmental regulations must be observed. Do not discharge into drains or sewers.

Color Code—Yellow: Reactive Hazard; Store ina location separate from other materials, especially flammables and combustibles. Store in tightly closed containersis a cool, well-ventilated area. Keep away from incompatible materials cited above. See OSHA Standard1910.104 and NFPA 43A Code for the Storage of Liquidand Solid Oxidizers for detailed handling and storageregulations.
