Section 3 - Hazards Identification

Appearance: blue-green solid.
Warning! Harmful if swallowed. Causes eye and skin irritation. May cause respiratory tract irritation.
Target Organs: Blood, kidneys, central nervous system, liver, gastrointestinal system, eyes, skin.


Potential Health Effects
Eye: Causes eye irritation.
Skin: Causes skin irritation. May be harmful if absorbed through the skin.
Ingestion: Harmful if swallowed. May cause irritation of the digestive tract. May cause nausea and vomiting.
