Warning! Causes irritation and possible burns by all routes of exposure.
Target Organs: Eyes, skin.

Potential Health Effects
Eye: May cause irreversible eye injury. Causes eye irritation and possible burns.
Skin: Causes skin irritation and possible burns.
Ingestion: May cause corrosion and permanent tissue destruction of the esophagus and digestive tract. Causes digestive tract irritation with possible burns.
