Hazard

Toxic by ingestion and inhalation, corrosive to tissue.

Health Hazard

Iodine trichloride is a highly corrosive sub stance. Skin contact can cause burn. Vaporsare irritating to the skin, eyes, and mucousmembranes. When heated at 77°C (170°F),it decomposes to chlorine and iodine mono chloride.

Fire Hazard

Noncombustible solid. Violent reaction oc curs with potassium. It reacts violently when heated with sodium, aluminum, phosphorus, phosphorus trichloride, or organic matter.

Purification Methods
