Fire-Fighter Precautions: Wear self-contained breathing apparatus, protective turnout gear
Explosion Risk: No data supporting explosion under normal conditions, but contact with reactive metals may release hydrogen gases
Special Firefighting Procedures: Use water spray to cool containers, keep away from runoff to prevent environmental contamination
Personal Precautions: Evacuate non-essential personnel, ensure adequate ventilation, use suitable protective gear
Environmental Precautions: Prevent entry to sewers and public waterways, notify appropriate authorities if large releases occur
Methods for Cleaning Up: Use inert absorbent (sand, vermiculite), collect spillage, avoid dust formation, transfer to containers for disposal
Small Spills: Sweep or scoop carefully, use damp cloth to minimize dust
Large Spills: Dike for later disposal, minimize spillage, avoid flushing with water unless heavily diluted
Decontamination: Wash area with water-neutralizing agents such as sodium bicarbonate
Handling: Use in chemical fume hood, minimize dust and aerosol generation, avoid contact with skin and eyes, use personal protective equipment
Hygiene Measures: Do not eat, drink, or smoke while handling chemical, wash thoroughly before breaks and after handling
Storage: Store tightly closed in corrosion-resistant containers, keep in cool, dry, well-ventilated area away from incompatible substances such as bases, oxidizing agents, and metals
