Methods for Cleanup: Sweep up using tools that minimize dust formation, collect in sealable containers for approved disposal.
Preventive Measures: Ventilate area, restrict access, avoid handling near food or water sources.
Handling: Use in well-ventilated space, avoid generating dust, wear required protective gear, prevent accidental contact or inhalation.
Storage Conditions: Cool, dry, well-ventilated space, away from ignition sources, incompatible chemicals (strong oxidizers, acids, bases).
Container Requirements: Tightly sealed, labeled containers made of compatible materials such as glass or HDPE; avoid metal containers where reaction risk exists.
Special Precautions: Store in original packaging as much as possible, avoid excess heat, moisture, and direct sunlight.
Exposure Limits: No established occupational exposure limits, follow general lab hygiene practices.
Engineering Controls: Local exhaust ventilation, use inside fume hood if dust or vapor risk increases.
Personal Protective Equipment: Nitrile gloves, chemical-resistant laboratory goggles, lab coat, particulate mask if powder is handled.
Hygiene Measures: Wash hands after use, do not eat or drink in work area, handle with clean gloves.
