Potassium ​Permanganate Safety

​Potassium permanganate is used in water treatment to control taste and odor problems. It is also used as an oxidant to precipitate iron and manganese from the water, and helps to inactivate pathogens. It is usually provided in powdered form.

This is a hazardous chemical, and the SDS for potassium permanganate should be obtained from the supplier and thoroughly reviewed. Follow all recommendations for personal protective equipment (PPE) and respiratory protection.

​​Contact with this material will cause burns to the skin, eyes and mucous membranes. Permanent eye damage including blindness could result. Potassium permanganate also causes damage to organs (respiratory system, central nervous system) through prolonged or repeated exposure. 

Follow the recommendations of the SDS regarding storage and handling of this material.  Potassium permanganate is incompatible with acids, peroxides, reducing agents and metal powders. Contact with hydrochloric acid liberates chlorine gas.

NIOSH provides a Chemical Safety Card for potassium permanganate.
