HEALTH HAZARD INFORMATION
Health Effects:
Target organs : respiratory system, central nervous system, blood, kidneys.
Acute
The fatal oral dose is estimated to be about 10g. Death may occur up to one
Swallowed:
month from time of poisoning. Swelling and irritation of the tissues in the
mouth and throat, nausea and vomiting may occur after swallowing solid
permanganate or concentrated solutions. A high-pitched noisy breathing
(stridor), slow pulse, shock and fall of blood pressure can occur. Liver and
kidney damage may develop.
Strong solutions and crystals can cause severe eye damage. Usually where the
Eye:
chemical touches the eye, a hardened, ulcer-like, dark brown coloured injury
develops. Swelling of the eyelids and the tender tissues surrounding the eye
(conjunctiva) and bleeding can occur. With prolonged contact, cloudiness and
brown discolouration of the front part of the eye (cornea) can result. Recovery
is usually complete, but in severe cases, permanent damage such as a dense,
white cloudiness of the cornea may occur. Dilute solutions are mildly irritating.
Concentrated solutions and the solid are highly corrosive. Contact with the skin
Skin:
can produce a burn with a thick, brownish-purple area of dead tissue. Dilute
solutions cause mild irritation.
High concentrations of potassium permanganate dust or mist (solutions) may
Inhaled:
cause irritation of the nose, throat and respiratory tract with symptoms such as
sore throat, coughing, shortness of breath and difficult breathing. Extreme
exposures could result in a build-up of fluids in the lungs (pulmonary oedema)
that might be fatal in severe cases. Symptoms of pulmonary oedema, such as
difficult breathing, may not appear until several hours after exposure.
Chronic intake of manganese compounds by ingestion or inhalation can result
Chronic:
in harmful effects on the central nervous system. Symptoms could include
difficulty in walking, weakness or cramps in the legs, trouble with memory and
judgement and unstable emotions.
First Aid:
Never give anything by mouth if victim is rapidly losing consciousness, or is
Swallowed:
unconscious or convulsing. Have victim rinse mouth thoroughly with water.
Do not induce vomiting. Have victim drink 240-300mL of water. If vomiting
occurs naturally, have victim lean forward to reduce risk of aspiration. Repeat
administration of water. Obtain medical attention immediately. Quickly
transport victim to an emergency facility.
Immediately flush the contaminated eye(s) with lukewarm, gently flowing
Eye:
water for 20 minutes, by the clock, holding the eyelid(s) open. Take care not to
rinse the contaminated water into the non-affected eye. If irritation persists,
repeat flushing. Obtain medical attention immediately.
Avoid direct contact with this chemical. As quickly as possible flush
Skin:
contaminated area with lukewarm, gently running water for at least 20 minutes,
by the clock. Under running water remove contaminated clothing, shoes and
leather goods. If irritation persists, repeat flushing. Obtain medical advice
immediately.
Remove source of contamination or move victim to fresh air. Obtain medical
Inhaled:
advice immediately.
Eye bath, safety shower
First Aid Facilities:
Treat symptomatically.
Advice to Doctor:
PRECAUTIONS FOR USE
5mg/m3, as manganese, dust and compounds.
Exposure Standards:
Use local exhaust ventilation, and process enclosure if necessary, to control
Engineering Controls:
airborne dust and mist. Use a corrosion resistant separate from other exhaust
ventilation systems. Exhaust directly to the outside. Locate dust collectors
outside or where permitted by regulation. Provide dust collectors with

explosion vents. Do not use combustible or organic materials such as wood in
the construction of ventilation systems and other engineering controls.
Respiratory Protection : None required where adequate ventilation conditions
Personal Protection:
exist. If airborne concentration exceeds TLV, a dust/mist respirator is
recommended. If concentration exceeds capacity of respirator, a self-contained
breathing apparatus is advised. Eye protection: Chemical safety goggles. A
face shield may also be necessary. Skin protection: Impervious gloves,
coveralls, boots and /or other resistant protective clothing.
Note: Contaminated clothing may be a fire hazard.
Not combustible but assists combustion of other substances.
Flammability:
SAFE HANDLING INFORMATION
Keep container tightly closed. Store in a cool, dry, well ventilated area, out of
Storage and Transport:
direct sunlight. Store separately and away from flammable and combustible
materials, reducing matrials and strong acids. Keep from contact with clothing.
Limit quantity of material in storage. Restrict access to storage area.
Transport: This material is classified a Class 5.1 Dangerous Good according to
the Australian code for the transport of Dangerous Goods. Proper shipping
name: Potassium permanganate. EPG Number 5A1. Packaging method 5.9.5.1.
Precautions: Restrict access to area until completion of clean-up. Ensure clean-
Spills and Disposal:
up is conducted by trained personnel only. Wear adequate personal protective
equipment. Ventilate area. Remove or isolate flammable and combustible
materials.
Clean-up: Do not touch spilled material. Prevent material from entering sewers
or confined spaces. Keep materials which can burn away from spilled material.
Stop or reduce leak if safe to do so. Contain spill with earth, sand or absorbent
material which does not react with spilled material. Small spills of solution:
Soak up spill with absorbent material which does not react with spilled
chemical. Put material in suitable, covered, labelled containers. Flush area with
water. Shovel spilled solid into clean, dry, labelled containers and cover. Flush
area with water. Large spills: Contact fire and emergency services and supplier
for advice. Contaminated absorbent material may pose the same hazard as the
spilled product.
Disposal: Review federal, state and local government requirements prior to
disposal. Store material for disposal as indicated in storage conditions. Note:
Waste potassium permanganate can be converted to a less hazardous material
by weak reducing agents such a hypo(sodium thiosulfate), bisulphites or ferrous
salts followed by neutralisation with soda ash or dilute HCl. Contact chemical
manufacturer/supplier for advice. Treatment of waste material must be done
only by specially trained personnel using appropriate facilities and protective
equipment. Disposal by secure landfill may be acceptable.
Potassium permanganate is an oxidising material that will increase the burning
Fire/Explosion Hazard:
rate or which may cause spontaneous ignition of combustible material with
which it comes in contact. Fire extinguishing agent: Water. Very large amounts
of water may be needed. Combustion products: When heated, potassium
permanganate gives off oxygen which increases the fire hazard.
