Explosion Risk: No dust explosion risk reported, but always handle with care around ignition sources
Personal Precautions: Wear chemical goggles, gloves, laboratory coat, respirator if dusting
Environmental Precautions: Avoid discharge to drains, sewers, or water bodies
Spill Clean-up: Sweep up material avoid creating dust, place in suitable closed containers for disposal, ventilate area, wash spill site after material pickup
Emergency Procedures: Evacuate unnecessary personnel from area, utilize containment methods for larger releases
Handling: Use in a properly ventilated fume hood, avoid breathing dust, wear suitable protective clothing, practice good hygiene after handling, minimize dust generation
Storage: Keep tightly sealed in a dry, cool, and well-ventilated place, avoid exposure to moisture or incompatible materials, do not store near oxidizing agents or sources of ignition
Special Considerations: Store away from strong acids and bases, keep container upright and secure to prevent spillage, ensure clear labeling
Incompatibilities: Strong oxidizers, acids, and alkalis can trigger hazardous reactions
Occupational Exposure Limits: No established OSHA, ACGIH, NIOSH exposure limits
Engineering Controls: Chemical fume hood, local exhaust ventilation, avoid confined spaces
Personal Protective Equipment: Chemical-resistant gloves, lab coat, safety goggles, use dust mask or respirator if risk of airborne particles
Hygiene Measures: Wash hands and face thoroughly after working, do not eat or drink in work area, remove contaminated garments before breaks
