First Aid Measures

Inhalation: Remove person to fresh air, keep comfortable, provide oxygen if breathing is difficult, get medical help if symptoms persist
Skin Contact: Rinse with plenty of water for 15 minutes, remove contaminated clothing, wash with mild soap, seek medical attention if irritation continues
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue rinsing, get immediate medical advice
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical attention or call Poison Center

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry powder, CO2, foam; avoid direct water jet
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, irritating vapors
Special Protective Equipment: Firefighters should use self-contained breathing apparatus, chemical-resistant suit
Advice for Firefighters: Keep containers cool, dike fire-control water for later disposal, evacuate area if necessary
Explosion Risk: Dust can form explosive mixtures with air; handle material away from ignition sources

Accidental Release Measures

Personal Precautions: Evacuate area, avoid breathing dust, ventilate area, wear gloves, goggles, protective clothing
Environmental Precautions: Prevent entry to sewers and waterways, notify authorities if significant spill occurs
Methods for Cleaning Up: Collect spilled material with non-sparking tools, use inert absorbent, store in closed containers, sweep up carefully to avoid dust
Decontamination: Wash spill area with plenty of soap and water, ventilate area after cleanup

Handling and Storage

Safe Handling Advice: Handle in well-ventilated area, minimize dust formation, avoid contact with eyes, skin, and clothing, do not breathe dust
