First Aid Measures

Inhalation: Move to fresh air, maintain comfort, seek medical attention for breathing difficulty
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek treatment for rash or irritation
Eye Contact: Immediately flush with water for at least 15 minutes, hold eyelids open, seek medical evaluation if irritation persists
Ingestion: Rinse mouth with water, offer water to drink, do not induce vomiting, contact medical professional if symptoms appear
Most Important Symptoms: Irritation of eyes, respiratory tract and skin; persistent cough on prolonged inhalation
Protection for First Responders: Use dust mask and gloves; avoid direct exposure to dust
Note: No specific antidote, treat symptomatically

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: High pressure water jets may raise dust clouds
Special Hazards: Fine dust may form explosive mixtures with air
Protective Equipment for Firefighters: Full protective clothing, approved respirator, self-contained breathing apparatus if dust present
Hazardous Combustion Products: Silicon oxides, may generate fumes in extreme heat
Additional Advice: Cool exposed containers with water mist to prevent dust dispersal; avoid inhalation of smoke or decomposition products

Accidental Release Measures

Personal Precautions: Minimize dust generation, wear respiratory protection, long sleeves, gloves and goggles
Environmental Precautions: Prevent spillage from entering drains, surface waters or soil
Methods for Clean-Up: Use vacuum or wet sweeping, avoid dry sweeping, transfer to labeled containers for disposal
Containment: Barricade area to prevent spread of material; use plastic sheeting if necessary to minimize dust
Decontamination: Wash area with water, ventilate enclosed spaces
Leak Response: Remove sources of ignition, ventilate, limit access until material is safely collected
Disposal of Spills: Follow local disposal regulations; never dispose into watercourses or open land
