Composition, Information on Ingredients
||Permanganic Acid (KMnO4), Potassium Salt
Symbols: XN O N
Risk Phrases: 22 8 50/53
Section 3 - Hazards
Appearance: dark purple crystals. Danger! Strong oxidizer.
Contact with other material may cause a fire. May cause kidney damage. May be
harmful if swallowed. May cause severe respiratory tract irritation with
possible burns. May cause severe digestive tract irritation with possible burns.
Causes severe eye and skin irritation with possible burns. Reproductively
Target Organs: Blood, kidneys, central nervous
system, liver, lungs, respiratory system, eyes, skin.
Potential Health Effects
Eye: Causes severe eye irritation and possible
burns. May cause chemical conjunctivitis and corneal damage.
Skin: May be harmful if absorbed through the skin. Causes
skin irritation and possible burns. May cause skin rash (in milder cases), and
cold and clammy skin with cyanosis or pale color. Skin contact can cause brown
stains in the area, and possible hardenin g of the outer skin layer.
Ingestion: Harmful if swallowed. May cause severe and
permanent damage to the digestive tract. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns. May cause liver and kidney
damage. May cause perforation of the digestive tract. May cause central nervous
system effects. May be harmful if swallowed. May form methemoglobin which in
sufficient concentration causes cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood). In high doses, manganese may increase
anemia by interfering with iron absorption. Manganese in general is a central
nervous system poison, and potassium permanganate has also been shown to have
Inhalation: Aspiration may lead to pulmonary
edema. Causes respiratory tract irritation with possible burns. May cause
central nervous system effects such as nausea and headache.
Chronic: Prolonged or repeated skin contact may cause
defatting and dermatitis. Effects may be delayed. Laboratory experiments have
resulted in mutagenic effects. Chronic manganese toxicity through inhalation may
result in "manganism", which is a disease of the central nervous system
involving psychic and neurological disorders. May cause kidney damage. May cause
adverse reproductive effects.
Section 4 - First Aid
Eyes: Get medical aid immediately. Do NOT allow
victim to rub or keep eyes closed. Extensive irrigation with water is required
(at least 30 minutes).
Skin: Get medical aid immediately.
Immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Wash clothing before reuse. Destroy
Ingestion: Do NOT induce vomiting. If
victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give
anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from
exposure and move to fresh air immediately. If breathing is difficult, give
oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device such as a
bag and a mask.
Notes to Physician: Absorption of this
product into the body may cause cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood). Moderate degrees of cyanosis need to be
treated only by supportive measures: bed rest and oxygen inhalation. If cyanosis
is severe, intravenous injection of Methylene blue, 1mg/kg of body weight may be
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. Strong oxidizer. Contact with combustible materials may cause a fire.
During a fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Some oxidizers may react explosively with
hydrocarbons(fuel). May accelerate burning if involved in a fire. Containers may
explode when heated.
Extinguishing Media: Cool containers
with flooding quantities of water until well after fire is out. For small fires,
do NOT use dry chemicals, carbon dioxide, halon or foams. USE WATER ONLY. For
large fires, flood fire area with water from a distance.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
NFPA Rating: (estimated) Health: 3;
Flammability: 0; Instability: 1; Special Hazard: OX
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
Spills/Leaks: Vacuum or sweep up material and
place into a suitable disposal container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately, observing
precautions in the Protective Equipment section. Avoid generating dusty
conditions. Provide ventilation. Do not get water inside containers. Do not use
combustible materials such as paper towels to clean up spill.
Section 7 - Handling
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Use only in a well-ventilated area.
Minimize dust generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid contact with clothing and other
combustible materials. Do not ingest or inhale. Do not store near combustible
materials. Discard contaminated shoes.
Storage: Keep away
from sources of ignition. Do not store near combustible materials. Keep
container closed when not in use. Store in a tightly closed container. Store in
a cool, dry, well-ventilated area away from incompatible substances.
Section 8 - Exposure
Controls, Personal Protection
Controls: Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower. Use adequate ventilation
to keep airborne concentrations low.
