First Aid Measures

Inhalation: Move to fresh air, keep at rest, seek medical advice if symptoms appear such as cough, sore throat, or breathing difficulty
Skin Contact: Remove contaminated clothing, rinse skin with water for several minutes, get medical attention if irritation develops
Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes, remove contact lenses, consult medical help if pain or redness stays
Ingestion: Rinse mouth, do not induce vomiting, seek urgent medical advice, note substance can be toxic if ingested
Note to Physician: Treat symptomatically, monitor respiratory and cardiovascular function, consider gastric lavage in severe cases

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Not Suitable: Direct water jet
Special Hazards: May emit toxic fumes including nitrogen oxides, hydrogen iodide, and iodine upon burning
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective gear
Additional Advice: Cool containers with water spray from a safe distance to prevent pressure build-up, evacuate area if fumes are released, avoid inhalation of smoke

Accidental Release Measures

Personal Precautions: Use chemical splash goggles, gloves, and laboratory coat, avoid breathing dust, ventilate area
Environmental Precautions: Prevent entry into sewers, soil, or waterways, alert local authorities in case of significant spillage
Cleanup Methods: Absorb with inert material such as sand or vermiculite, collect spills in labeled containers for disposal, clean area with water and detergent, handle as hazardous waste
Decontamination: Use appropriate personal protective equipment, avoid creating dust, wash surface thoroughly after cleanup

Handling and Storage

Handling: Avoid direct contact with skin and eyes, work in a fume hood or well-ventilated area, minimize dust generation, keep container tightly closed
