Fire-Fighting Instructions: Keep upwind of fire, use water spray to cool unopened containers exposed to fire. Remove materials from fire area when safe
Personal Protection: Use gloves, safety goggles, and dust mask to prevent contact and inhalation of dust; restrict access to contaminated area
Environmental Precautions: Prevent entry to waterways, drains or soil in case of large spills
Cleanup Procedures: Sweep up spilled material, place in clean, dry containers for reuse or disposal. Wash spill site with water after material pickup completed
Safe Handling: Avoid generating dust. Use adequate ventilation. Handle with clean hands, keep away from strong acids
Storage Conditions: Store in a tightly closed container in a cool, dry, well-ventilated place free from direct sunlight. Keep away from incompatible substances and moisture
