General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
Fresh air. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
In case of skin contact
Wear protective gloves when administering first aid. First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
In case of eye contact
Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
If swallowed
Rinse mouth. If within a few minutes after ingestion, one small glass of water may be given to drink. Do NOT induce vomiting. Refer immediately for medical attention.
4.2 Most important symptoms/effects, acute and delayed
Burns and stains the skin dark brown. If ingested will cause severe distress of gastro-intestinal system. May be fatal if over 4 oz. are consumed. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
FOLLOWING INGESTION OF TABLETS, GASTRIC LAVAGE & SUPERVISION ON SURGICAL UNIT IS PROPOSED. OPERATION SHOULD BE CONSERVATIVE IF DIGESTIVE PERFORATION IS PRESENT, ALTHOUGH IT IS EXTREMELY RARE.

10.2 Chemical stability
STABLE IN AIR AND LIGHT; SOLN ARE UNSTABLE
10.3 Possibility of hazardous reactions
MODERATE, BY CHEMICAL REACTION.POTASSIUM PERMANGANATE is a very powerful oxidizing agent, particularly in acidic surroundings. Reacts with incandescence with aluminum carbide [Mellor 5:872. 1946-47]. Grinding with antimony or arsenic causes ignition of the metals [Mellor 12:322. 1946-47]. Mixtures with acetic acid or acetic anhydride may explode if not kept cold [Von Schwartz 1918. p. 34]. Explosions can occur when acidified solutions come in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or organic matter. Contact with glycerol may produce an explosion [Pieters 1957. p. 30]. Contact with concentrated hydrogen peroxide solution can produce an explosion [Haz. Chem. Data 1973. p. 230]. Contact with solid hydroxylamine produces an immediate white flame [Mellor 8:294. 1946-47]. Transport through a polypropylene tube ignited the tube [MCA Case History 1842. 1972]. Mixing with concentrated sulfuric acid in a vessel containing moisture caused an explosion (due to formation of manganese heptoxide) [Delhez 1967].
