USES AND HANDLING ISSUES

Relevant identified uses

Scandium(III) chloride is found in some halide lamps, optical fibers, electronic ceramics, and lasers. [3]

Handling considerations

 Wear suitable gloves and eye/face protection.
 In case of contact with eyes, rinse immediately with   plenty of water and seek medical advice. [1]

Handling: Minimize dust generation and accumulation. Avoid breathing dust, mist, or vapor. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse. 
Storage: Store in a tightly closed container. Keep under an argon blanket. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from moisture. [4]
