During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Chronic exposure to fluoride compounds may cause systemic toxicity. Rare earth compounds may cause sensitivity to heat and itching, increased awareness to odor and taste, and delayed blood clotting leading to hemorrhages.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.

Causes skin irritation.
Causes eye irritation.
