CRITICAL WARNINGS:

1. May cause serious eye damage. Eye protection is mandatory. Seek immediate medical attention upon contact.

2. Irritant. May cause irritation to skin and respiratory tract. Use appropriate protective equipment.

3. Hygroscopic (absorbs moisture). Store in closed containers in dry environment.

4. Decomposes upon heating and may release organic decomposition products.

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

6. Magnetic material applications require high purity (≥99.99%).

7. Not approved for food and cosmetics. Prohibited in cosmetic formulations under CLP/REACH.

8. Incompatibilities: Strong bases, reducing agents, oxidizing agents, moisture.

9. Hygiene Requirement: Wash hands thoroughly after use. Remove contaminated clothing.

BEST PRACTICE RECOMMENDATIONS:
