Suitable Extinguishing Media: Water spray, dry chemical powder, foam, carbon dioxide
Unsuitable Media: Do not use water jets directly on the burning material
Hazards from Combustion Products: May produce toxic fumes of sodium oxides and iodine compounds
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective gear
Specific Hazards: Material not combustible but may decompose at high temperature, releasing hazardous iodine fumes
Personal Precautions: Evacuate personnel, ventilate area, use personal protective equipment
Environmental Precautions: Prevent entry into drains or waterways, inform authorities of large spills
Methods for Cleanup: Sweep or scoop spilled material into containers, avoid creating dust, wipe remaining residue with damp cloth, dispose of in compliance with local regulations
Reference to Other Sections: Use recommended protective measures from Sections Exposure Controls and Disposal Considerations
Safe Handling Advice: Work in well-ventilated area, minimize formation of dust, avoid contact with skin and eyes, wash hands after use
Storage Conditions: Store in tightly closed containers, keep in dry, cool, well-ventilated place, protect from moisture and light
Incompatible Materials: Strong acids, oxidizing agents, alkaloids, metallic salts
Segregation Information: Keep away from incompatible substances to prevent hazardous reactions
Control Parameters: Occupational Exposure Limits not specifically established for sodium iodide, but observe exposure limits for iodine compounds
Engineering Controls: Use fume hood or local exhaust, maintain good air circulation, provide eyewash stations
Personal Protective Equipment: Safety goggles, chemical-resistant gloves (nitrile or rubber), lab coat
