Section 3 Hazards Identification
1. Eye Contact
Potassium permanganate is damaging to eye tissue on contact. It may cause
severe burns that result in damage to the eye.
2. Skin Contact
Contact of solutions at room temperature may be irritating to the skin,
leaving brown stains. Concentrated solutions at elevated temperature and
crystals are damaging to the skin.
3. Inhalation
Acute inhalation toxicity data are not available. However, airborne
concentrations of potassium permanganate in the form of dust or
mist may cause damage to the respiratory tract.
4. Ingestion
Potassium permanganate, if swallowed, may cause severe burns to mucous
membranes of the mouth, throat, esophagus, and stomach.
Section 4 First Aid Measures
1. Eyes
Immediately flush eyes with large amounts of water for at least 15 minutes
holding lids apart to ensure flushing of the entire surface. Do not
attempt to neutralize chemically. Seek medical attention immediately. Note
to physician: Soluble decomposition products are alkaline.
Insoluble decomposition product is brown manganese dioxide.
2. Skin
Immediately wash contaminated areas with large amounts of water. Remove
contaminated clothing and footwear. Wash clothing and
decontaminate footwear before reuse. Seek medical attention immediately
if irritation is severe or persistent.
3. Inhalation
Remove person from contaminated area to fresh air. If breathing has
stopped, resuscitate and administer oxygen if readily available. Seek
medical attention immediately.
4. Ingestion
Never give anything by mouth to an unconscious or convulsing person.
If person is conscious, give large quantities of water. Seek medical
attention immediately.

Reactivity Hazard 0 = Materials which in themselves are normally stable,
even under fire exposure conditions, and which are not reactive with water.
Special Hazard OX = Oxidizer
*National Fire Protection Association 704
FIRST RESPONDERS:
Wear protective gloves, boots, goggles, and respirator. In case of fire,
wear positive pressure breathing apparatus. Approach site of incident with
caution. Use Emergency Response Guide NAERG 96 (RSPA P5800.7). Guide No. 140.
FLASHPOINT None
FLAMMABLE OR EXPLOSIVE LIMITS Lower: Nonflammable Upper: Nonflammable
EXTINGUISHING MEDIA Use large quantities of water. Water will turn pink to
purple if in contact with potassium permanganate. Dike to contain. Do not
use dry chemicals, CO 2 , Halon (r) or foams.
SPECIAL FIREFIGHTING PROCEDURES If material is involved in fire, flood with
water. Cool all affected containers with large quantities of water.
Apply water from as far a distance as possible. Wear self-contained
breathing apparatus and full protective clothing.
Red - Flammability 0
White - Special OX
Blue - Health 1
Yellow - Stability 0.
Section 6 Accidental Release Measures
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED
Clean up spills immediately by sweeping or shoveling up the material. Do not
return spilled material to the original container. Transfer to a clean metal
drum. EPA banned the land disposal of D001 ignitable waste oxidizers. These
wastes must be deactivated by reduction. To clean floors, flush with
abundant quantities of water into sewer, if permitted by Federal, State, and
Local regulations. If not permitted, collect water and treat chemically
(Section 13).
PERSONAL PRECAUTIONS
Personnel should wear protective clothing suitable for the task. Remove all
ignition sources and incompatible materials before attempting clean-up.
Section 7 Handling and Storage
WORK/HYGENIC PRACTICES
Wash hands thoroughly with soap and water after handling potassium
permanganate, and before eating or smoking. Wear proper protective
equipment. Remove contaminated clothing.
VENTILATION REQUIREMENTS
Provide sufficient area or local exhaust to maintain exposure below the
TLV-TWA.
CONDITIONS FOR SAFE STORAGE
Store in accordance with NFPA 430 requirements for Class II oxidizers.
Protect containers from physical damage. Store in a cool, dry area in
closed containers. Segregate from acids, peroxides, formaldehyde, and all
combustible, organic or easily oxidizable materials including anti-freeze
and hydraulic fluid.
Section 8 Exposure Controls/Personal Protection
RESPIRATORY PROTECTION
In the case where overexposure may exist, the use of an approved NIOSH-MSHA
dust respirator or an air supplied respirator is advised.
Engineering or administrative controls should be implemented to control dust.
EYE
Faceshield, goggles, or safety glasses with side shields should be worn.
Provide eye wash in working area.
GLOVES
Rubber or plastic gloves should be worn.
OTHER PROTECTIVE EQUIPMENT
Normal work clothing covering arms and legs, and rubber or plastic apron
should be worn..

Section 11 Toxicological Information

(Ref. Handbook of Poisoning: Prevention, Diagnosis & Treatment,
Twelfth Edition)
EFFECTS OF OVEREXPOSURE
1. Acute Overexposure
Irritating to body tissue with which it comes into contact.
2. Chronic Overexposure
No known cases of chronic poisoning due to potassium permanganate have been
reported. Prolonged exposure, usually over many years, to heavy
concentrations of manganese oxides in the form of dust and fumes, may lead
to chronic manganese poisoning, chiefly involving the central nervous system.
3. Carcinogenicity
Potassium permanganate has not been classified as a carcinogen by OSHA, NTP,
IARC.
4. Medical Conditions Generally Aggravated by Exposure
Potassium permanganate will cause further irritation of tissue, open wounds,
burns or mucous membranes.
Registry of Toxic Effects of Chemical Substances
RTECS #SD6476000.Section 12 Ecological Information
Entry to the Environment
Potassium Permanganate has a low estimated lifetime in the environment,
being readily converted by oxidizable materials to insoluble
manganese dioxide (MnO2 ).
Bioconcentration Potential
In non-reducing and non-acidic environments manganese dioxide (MnO2 ) is
insoluble and has a very low bioaccumulative potential.
Aquatic Toxicity
Rainbow trout, 96 hour LC 50 : 1.8 mg/L
Bluegill sunfish, 96 hour LC 50 : 2.3 mg/L
Section 13 Disposal Consideration
DEACTIVATION OF D001 IGNITABLE WASTE OXIDIZERS BY CHEMICAL REDUCTION
Reduce potassium permanganate in aqueous solutions with sodium thiosulfate
(Hypo), or sodium bisulfite or ferrous salt solution. The
thiosulfite or ferrous salt may require some dilute sulfuric acid to promote
rapid reduction. If acid was used, neutralize with sodium bicarbonate
to neutral pH. Decant or filter, and mix the sludge with sodium carbonate and
deposit in an approved landfill. Where permitted, the sludge
can be drained into sewer with large quantities of water. Use caution when
reacting chemicals.
