SECTION 20: CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

1. Flammable in fine powder form. May form dust explosions in air. Keep away from heat and sparks.

2. Irritant. Fine particles may irritate skin, eyes and respiratory tract when inhaled. Use appropriate protective equipment.

3. Slowly oxidizes in air. Store in closed containers away from moisture and oxidizing agents.

4. Inert atmosphere recommended for storage.

5. Rare earth metal requires special handling and purity considerations.

6. Magnetic applications require high purity (≥99.9%).

7. Incompatibilities: Strong acids, halogens, oxidizing agents, moisture.

8. Hygiene Requirement: Wash hands thoroughly after use.

BEST PRACTICE RECOMMENDATIONS:

9. NdFeB Magnet Production:
Add dysprosium powder to NdFeB magnets to improve high-temperature performance. Increases coercivity.

10. Lighting Applications:
Use to increase brightness and color quality in metal halide lamps.

11. Aerospace and Engineering:
Use in Terfenol-D alloy for sensors, actuators and transducers.

12. Laser and Optical Materials:
Use in special glass and phosphor production.

13. Advanced Manufacturing:
Powder form is suitable for 3D printing (additive manufacturing) and special alloy production.

14. Use:
Use in well-ventilated areas; Avoid dust formation; Take static electricity precautions.

15. Personal Protective Equipment:
Use safety goggles, protective clothing, protective gloves (nitrile, neoprene), NIOSH approved dust mask.

16. Hygiene:
Do not eat, drink or smoke while using; Wash hands thoroughly after use; Do not take contaminated work clothes home.

17. Storage:
Store in cool, dry, well-ventilated area; Keep away from moisture and oxidizing agents; Store in closed, airtight containers; Inert atmosphere recommended.

18. Spill Response:
Avoid dust formation; Vacuum or sweep; Place in closed containers; Do not allow to enter drains or waterways.

19. Disposal:
Dispose in accordance with local, regional and national regulations; Contact licensed waste disposal services for rare earth metals.

20. Purity Requirements:
Select the correct purity grade according to the application. High purity (≥99.9%) is required for magnetic applications.
