Odor: Odorless
Common Uses: Research laboratories, electronics, organic synthesis
Molecular Weight: 589.68 g/mol
Hazard Class: Not generally classified as highly hazardous
Main Health Risks: Eye and skin irritation, respiratory discomfort if dust is inhaled
Symbol: Not labeled as a dangerous substance in the way that many industrial chemicals are
Precautionary Statements: Avoid breathing dust, avoid contact with eyes, skin and clothing
Chemical Identity: Bismuth(III) iodide
CAS Number: 7787-64-6
Purity: Typically greater than 98% in laboratory uses
Other Ingredients: Impurities generally not present in significant quantities
Eye Contact: Rinse with plenty of water, remove contact lenses if present and easy to do
Skin Contact: Wash gently with soap and water
Inhalation: Move to fresh air, rest and breathe slowly
Ingestion: Rinse mouth thoroughly, seek medical advice
Flash Point: No available data on flammability due to lack of combustibility
Extinguishing Media: Use agents suitable for surrounding fire, such as foam, CO2, dry chemical
Protective Gear: Wear self-contained breathing apparatus and protective clothing when dealing with potential fumes
Key Concern: Bismuth(III) iodide does not burn easily, but it can decompose at high heat to release fumes of iodine and bismuth oxides
Personal Precautions: Wear gloves and eye protection, avoid sweeping dust into the air
Containment: Prevent further spillage if it can be done without risk
Cleanup Methods: Scoop up material, collect in a container for disposal, wash area with water
Environmental Caution: Avoid letting material enter drains or water courses
Handling: Use in a well-ventilated area, minimize dust generation
Storage: Keep container tightly closed, store in a cool, dry place away from strong acids and oxidizers
Incompatible Materials: Strong oxidizing agents, acids, reducing agents
Respiratory Protection: Use dust masks in poorly ventilated areas or if dust level is excessive
Eye Protection: Safety goggles or protective glasses
Skin Protection: Gloves made from materials like nitrile or latex
Engineering Controls: Local exhaust ventilation recommended in laboratory settings
Physical State: Crystalline solid
Color: Dark brown to black
Melting Point: Around 411°C
Solubility: Insoluble in water, soluble in certain acids and alkalis
Density: About 5.78 g/cm³
Odor: Odorless
pH: Not applicable due to insolubility
Chemical Stability: Stable at room temperature under normal storage conditions
Reactivity: Reacts vigorously with strong acids or oxidizers, may form toxic gases
Decomposition Products: Iodine, bismuth oxides on thermal decomposition
Other Concerns: Avoid creating dust clouds, which can be hazardous in enclosed spaces
Acute Toxicity: Low oral toxicity in animal studies, but not fully characterized in humans
Chronic Risks: Long-term effects not well studied, but prolonged inhalation of dust should be avoided
Sensitization: No strong evidence of allergic reactions
General Health Perspective: Exercise caution in routine handling, avoid unnecessary exposure
Aquatic Toxicity: Could pose moderate risk to aquatic life if released in substantial quantities
Persistence: No rapid degradation in the environment
Bioaccumulation: No detailed data available, likely to remain stable in soil and water
General Recommendation: Keep spills to a minimum, prevent entry into open water
Preferred Method: Treat as hazardous laboratory waste
Disposal Procedures: Hand over to licensed waste handler, avoid disposing down the drain
Recycling Potential: Low, not usually recycled due to small usage amounts in most labs
