Hazards from Combustion: May emit toxic fumes of iodine, phosphorus oxides, and carbon oxides
Personal Protective Equipment: Firefighters should wear full protective gear, including self-contained breathing apparatus, chemical-resistant suits
Special Procedures: Evacuate area, prevent run-off from contaminating water sources, use caution during chemical fires due to possible release of hazardous gases
Personal Precautions: Evacuate unprotected personnel, ventilate affected area, wear protective gloves, eyewear, approved respirator
Environmental Precautions: Prevent chemical release into drains, surface water, and soil
Methods for Containment: Absorb spill with inert material such as sand or vermiculite, place waste in suitable disposal containers
Methods for Clean-Up: Sweep up carefully to minimize airborne dust, decontaminate area with soap and water, dispose of according to regulations
Handling: Use with adequate ventilation, avoid creating dust, do not eat, drink, or smoke during handling, wash hands and face after handling
Protection: Handle using appropriate chemical-resistant gloves, goggles, and protective clothing
Storage: Store in original, tightly closed containers in a cool, dry, well-ventilated location, away from incompatible substances and sunlight
