Suitable Extinguishing Media: Carbon dioxide, dry chemical, water spray, foam. Use extinguishing media appropriate for surrounding fire.
Hazards from Combustion: May evolve hazardous fumes including carbon oxides, nitrogen oxides, hydrogen fluoride.
Special Protective Equipment: Wear positive pressure self-contained breathing apparatus and complete protective clothing.
Firefighting advice: Isolate area. Avoid inhaling vapor or combustion gases. Cool containers exposed to flames with water spray.
Personal Precautions: Evacuate unnecessary personnel. Wear suitable personal protective equipment including gloves, goggles, and respirator.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid release to drains, watercourses, and soil.
Cleanup Methods: Absorb with inert material such as dry sand or earth. Place in properly labeled container for disposal. Clean area thoroughly with water.
Containment: Stop the leak if without risk. Isolate spill area.
Handling: Avoid breathing dust, vapor, or mist. Avoid contact with skin and eyes. Use only with adequate ventilation. Wash thoroughly after handling.
