WHMIS (Manganese dioxide)

Workplace Hazardous Materials Information System

WHMIS 2015 classification - Note to reader

• Oxidizing solids - Undefined category1 2 3 4
• This hazard class has been assigned according to the information obtained from the consulted scientific literature, but it does not allow to specify the hazard category.

• Specific target organ toxicity - repeated exposure - Category 12 5

Danger

Oxidizing Solids : Undefined hazard statement
Causes damage to organs through prolonged or repeated exposure (H372)

Ingredient disclosure

Comments: Due to the lack of data, classification regarding specific organ toxicity - repeated exposure (H372) was established by analogy to Manganese and maganese inorganic compounds.
