Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Unsuitable Media: High volume water jet may spread dust
Specific Hazards: Dust may form explosive mixtures with air. Fires produce irritating or toxic fumes including carbon oxides.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear
Special Procedures: Keep containers cool using water spray to prevent pressure build-up. Remove from fire area if safe.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide

Accidental Release Measures

Personal Precautions: Wear appropriate protective equipment including gloves, goggles, and dust mask. Ensure adequate ventilation.
Environmental Precautions: Prevent further leakage or spillage if safe. Avoid release to waterways and drains.
Cleaning Methods: Sweep or vacuum up spilled material. Avoid generating dust. Place in suitable container for disposal.
Other Considerations: Clean spill area thoroughly with water to remove residues.

Handling and Storage

Safe Handling: Avoid dust formation. Do not breathe dust. Handle in well-ventilated areas. Wear personal protective equipment.
