2.hazards identification

emergency overview
harmful in contact with skin. causes burns. may cause sensitization by skin contact.hygroscopic (absorbs moisture from the air).
potential health effects

eye:
causes severe eye irritation and possible burns.

skin:
harmful if absorbed through the skin. causes skin burns. may cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. may cause depigmentation of the skin.
