Advice for Firefighters: Wear self-contained breathing apparatus and full protective clothing
Fire/Explosion Hazards: Product does not support combustion but may promote flame spread of other materials
Other Information: Prevent water runoff from entering storm drains or surface waters

Accidental Release Measures

Personal Precautions: Wear chemical-resistant gloves, goggles, protective clothing
Emergency Procedures: Evacuate spill area for large releases; ventilate enclosed spaces
Environmental Precautions: Block drains; avoid release to surface water or soil
Cleanup Methods: Collect spilled powder with non-sparking tools; sweep or shovel into suitable containers; wash area with water but prevent runoff
Disposal Guidance: Dispose of cleanup residues according to local environmental regulations

Handling and Storage

Safe Handling: Use only with protective gloves and eyewear; limit direct body contact; avoid creating dust or aerosols
Technical Measures: Ground and bond containers if transferring large volumes; use only in well-ventilated spaces
