GHS Hazard Classification

Globally Harmonized System classification per ECHA C&L inventory and ILO/WHO International Chemical Safety Cards.

Short-term Exposure Effects
The substance is irritating to the eyes and skin. The substance may cause effects on the blood. This may result in the formation of methaemoglobin.
Long-term Exposure Effects
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood. This may result in anaemia.
Routes of Exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.
