Spill Cleanup Methods: Scoop or sweep up spilled material into appropriately labeled containers, avoid dust creation, wash spill area thoroughly with water after material pick-up
Waste Disposal: See Disposal Considerations
Emergency Procedures: Evacuate unnecessary personnel, provide adequate ventilation, restrict access until cleaning completed
Handling: Use in well-ventilated areas, minimize creation of dust, avoid contact with skin, eyes, and clothing, wash hands and exposed skin after handling, keep containers closed when not in use
Storage Conditions: Store in cool, dry, well-ventilated location, protect containers from moisture, segregate from strong acids and oxidizing agents
