Manganese powder is primarily utilised in industrial and laboratory settings. Its applications include alloy production, particularly in the manufacturing of steel and non-ferrous alloys. Additionally, manganese powder finds use in chemical synthesis, battery production, and as a component in various industrial processes.

According to Regulation (EC) No. 1272/2008, Manganese Powder is not classified as a hazardous substance or mixture. It does not meet the criteria for classification as a hazardous material based on its properties and composition.

Safe Handling:

When handling manganese powder, it is essential to provide appropriate exhaust ventilation in areas where dust is formed to minimise exposure. Personal protective equipment, including gloves, should be worn to prevent skin contact. Additionally, proper glove removal techniques should be employed to avoid touching the outer surface of gloves. Hands should be washed thoroughly after handling manganese powder.


To ensure safe storage of manganese powder, it should be kept in a cool, dry, and well-ventilated area. Containers should be tightly closed to prevent moisture absorption. Given its sensitivity to moisture, manganese powder should be handled and stored under inert gas conditions. It is classified as a non-combustible solid, and adherence to relevant storage guidelines, such as Storage class (TRGS 510), is advisable.

Proper disposal of manganese powder involves adherence to applicable regulations and guidelines governing hazardous waste disposal. Contaminated gloves used during handling should be disposed of in accordance with relevant laws and good laboratory practices. It is imperative to prevent further leakage or spillage into the environment. Discharge into drains must be avoided to minimise environmental contamination. Disposal methods should align with established protocols for hazardous material disposal to ensure safety and environmental protection.
