Chemical dangers
The substance is a strong oxidant and reacts with combustible and reducing materials, causing fire and explosion hazard.

Occupational exposure limits
TLV not established.
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
May cause mechanical irritation to the eyes and the respiratory tract. The substance may cause effects on the blood when ingested, resulting in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.
