Fire Fighting Instructions: Move containers away from fire area if safe, cool adjacent containers with water spray to prevent heating
Combustion Products: Hydrogen fluoride, sulfur oxides, sodium oxides
Personal Precautions: Avoid dust formation, ventilate area, wear appropriate personal protective equipment including gloves, safety goggles, dust mask/respirator
Environmental Precautions: Prevent material from entering drains, surface water, soil, or sewers, notify authorities if product enters water system
Methods for Clean-Up: Sweep up or vacuum without creating dust, collect in suitable labeled containers, wash spill site after material clean-up is complete
Suitability of Methods: Use non-sparking tools, prevent spillage from spreading, avoid use of water to avoid spreading powder
Handling Waste: Dispose recovered material as chemical waste according to applicable regulations
Handling: Work in a well-ventilated area, avoid breathing dust, avoid contact with skin and eyes, prevent formation of dust clouds, use mechanical local exhaust at relevant places
