Praseodymium optical properties for use in amplification of telecommunication systems, including as a doping agent in fluoride fibers. It is also used in the scintillator for medical CAT scans. Used as additive for special steel, non-ferric alloy, hydrogen storage alloy, also reducer for making other rare Earth metal.

Hazard Statements: H228-H260-H500
Flammable solid. In contact with water releases flammable gases which may ignite spontaneously. May form combustible dust concentrations in air
Precautionary Statements: P210-P223-P231+P232-P240-P241-P280-P335+P334-P370+P378q-P501c
Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Keep away from any possible contact with water, because of violent reaction and possible flash fire. Handle under inert gas. Protect from moisture. Ground/bond container and receiving equipment. Use explosion-proof electrical/ventilating/lighting/ equipment. Wear protective gloves/protective clothing/eye protection/face protection. Brush off loose particles from skin. Immerse in cool water/wrap in wet bandages. In case of fire: Use CO2, dry chemical, or foam Dispose of contents/ container to an approved waste disposal plant
