Section 3 - Hazards Identification


Appearance: clear yellow liquid.
Danger! Toxic if absorbed through the skin. May be fatal if inhaled. Causes burns by all exposure routes. Harmful if swallowed. Lachrymator (substance which increases the flow of tears). Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. May cause allergic skin reaction. May cause central nervous system effects. May cause liver and kidney damage.
Target Organs: Blood, kidneys, central nervous system, liver, spleen, respiratory system, gastrointestinal system, eyes, skin.

Potential Health Effects
Eye: Causes eye burns. Lachrymator (substance which increases the flow of tears).
Skin: Causes skin burns. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Toxic in contact with skin.
Ingestion: Harmful if swallowed. Causes gastrointestinal tract burns. May cause liver and kidney damage.
Inhalation: May be fatal if inhaled. Causes chemical burns to the respiratory tract. May cause central nervous system effects.
