| Hazard Information | Back Directory | [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. | [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. | [Hazard]
Oxidizing material. Fire and explosion risk in contact with organic materials. Toxic by ingestion. | [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 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. See
also First Aid section in “Barium” entry. | [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. | [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. | [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. | [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. |
