Advice for Firefighters: Evacuate area, use water spray to cool surrounding containers, avoid inhalation of smoke or fumes
Personal Precautions: Avoid inhalation of dust; wear dust mask and eye protection
Environmental Precautions: Prevent large releases from entering drains or waterways
Cleanup Methods: Sweep or vacuum gently to minimize dust; place in labeled containers for disposal; use non-sparking tools
Spill Response: Avoid dry sweeping; use water spray to minimize airborne particles in confined spaces
Disposal: Collect for recovery or disposal according to local regulations
Handling: Keep containers tightly closed; handle in accordance with good industrial hygiene; minimize dust generation; use local exhaust ventilation in confined areas
