Description
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.
Chemical Properties
Barium permananganate is a brownish-violet,
dark purple to black crystalline solid.
Uses
As dry cell depolarizer.
General Description
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.
Air & Water Reactions
Soluble in water.
Reactivity Profile
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.
Hazard
Oxidizing material. Fire and explosion risk in contact with organic materials. Toxic by ingestion.
Health Hazard
Inhalation or contact with eyes or skin causes irritation. Ingestion causes abdominal pain, nausea, vomiting, pallor, shortness of breath.
Fire Hazard
Behavior in Fire: Can increase the intensity of fire.
Safety Profile
Probably an irritant. A powerful oxidizer. When heated to decomposition it emits acrid smoke and irritating fumes. See also BARIUM COMPOUNDS.
Potential Exposure
It is used to make dry cells and other
permanganates, and as a disinfectant.
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. See also First Aid section in“Barium” entry.
storage
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.
Shipping
UN1448 Barium permanganate, Hazard Class:
5.1; Labels: 5.1—Oxidizer, 6.1—Poisonous materials.
Incompatibilities
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.
Waste Disposal
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.
