Appearance: white pellets.
Danger! May be fatal if inhaled. Causes eye, skin, and respiratory tract irritation. Harmful if swallowed. May cause allergic skin reaction. May cause cancer in humans.
Target Organs: Lungs, skin.

Potential Health Effects
Eye: Causes eye irritation.
Skin: Causes skin irritation. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material.
Ingestion: Harmful if swallowed. May cause irritation of the digestive tract.
Inhalation: May be fatal if inhaled. Causes respiratory tract irritation.
