General Description
White to off-white solid. Sinks and mixes with water. (USCG, 1999)

Hazards

Reactivity Alerts
none
Air & Water Reactions
Deliquescent. Water soluble. Adding calcium chloride to hot water caused violent boiling, [MCA Case History No. 69].
Fire Hazard
No information available.
Health Hazard
Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes (particularly by dust) causes irritation and possible transient corneal injury. Contact of solid with dry skin causes mild irritation; strong solutions can cause marked irritation, even a superficial burn. (USCG, 1999)
Reactivity Profile
Bromine trifluoride rapidly attacks calcium chloride [Mellor 2 Supp. 1:164, 165 1956]. Long term exposure of calcium chloride solution upon a zinc coated galvanized iron vessel caused slow evolution of hydrogen which ignited and exploded [Bretherick, 5th Ed., 1995].
