Advice for Firefighters: Cool containers exposed to fire with water spray, evacuate area if large fire occurs

Accidental Release Measures

Personal Precautions: Use protective gloves and eyewear, avoid inhaling dust, ventilate area
Environmental Precautions: Prevent powder from entering drains, surface water or soil
Methods for Containment: Sweep or vacuum up spilled product, avoid creating dust, transfer to suitable container for disposal
Clean-Up Procedures: Wash spill area with water, avoid dry sweeping large quantities

Handling and Storage

Handling: Use appropriate personal protection, avoid generating dust, wash hands after handling
Storage: Store in a cool, dry, well-ventilated place, keep container tightly closed, keep away from incompatible materials such as strong oxidizers, prevent direct exposure to sunlight, protect from moisture
