Advice: Maintain safe distance, contain runoff to avoid contamination of water supplies
Personal Precautions: Avoid contact with skin and eyes, remove ignition sources, ventilate area, ensure use of appropriate personal protective gear
Clean-up Methods: Sweep or shovel spilled material into containers for disposal, avoid raising fine dust, flush affected area with water only after all solid has been removed
Environmental Precautions: Prevent product from entering drains, sewers, water sources, notify local authorities if contamination occurs
Containment: Dike spilled material, isolate non-essential personnel
Handling Procedures: Use only in well-ventilated areas, avoid creating dust clouds, wear protective gloves, goggles, and clothing, handle away from food and beverages
