Fire-Fighting Measures

Suitable Extinguishers: Water spray, dry chemical, foam, carbon dioxide
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, possible aromatic compounds
Protective Equipment: Self-contained breathing apparatus, protective clothing to prevent contact with skin and eyes
Special Hazards: Dust formed during fire may pose explosion risk if mixed with air; use caution with dust clouds
Fire-Fighting Procedures: Keep containers cool using water spray; avoid breathing smoke or combustion gases; withdraw from area if fire gets out of control

Accidental Release Measures

Personal Precautions: Wear gloves, goggles, dust mask; prevent contact with skin and eyes
Environmental Precautions: Avoid runoff into drain, surface waters, and soil
Cleanup Methods: Sweep up and place in suitable container for disposal; ventilate spill area; avoid creating dust; clean surfaces with damp cloth
Disposal: Follow local regulations for hazardous chemical disposal

Handling and Storage

Safe Handling: Only open containers in well-ventilated areas; avoid dust generation; wash hands after handling; do not eat, drink, or smoke around the product
Safe Storage: Store in tightly closed original container away from moisture and incompatible substances; keep container in cool, dry, well-ventilated place; segregate from strong oxidizers; keep away from food and beverages
