General Advice: Seek immediate medical help in serious cases or if symptoms persist
Inhalation: Remove affected individual to fresh air, keep them comfortable, support breathing if needed, consult medical personnel if symptoms like coughing or throat irritation do not ease
Skin Contact: Remove contaminated clothing, rinse area with plenty of water and mild soap, consult a healthcare expert if irritation or redness develops or does not go away
Eye Contact: Flush eyes cautiously with water for at least 15 minutes, lift eyelids to ensure thorough irrigation, remove contact lenses if present and easy to do, get medical attention
Ingestion: Rinse mouth with water if person is conscious, do not induce vomiting, consult poison control or medical provider
Symptoms: Skin redness, sore or watery eyes, cough, abdominal pain, possible nausea after swallowing
Treatment of Exposure: Symptomatic and supportive care recommended, bring product label or datasheet for reference
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or alcohol-resistant foam, avoid water spray which may spread material

Protective Equipment for Firefighters: Wear approved, full protective clothing including self-contained breathing apparatus
Special Precautions: Avoid inhalation of combustion products, isolate fire area
Combustion Byproducts: Tin oxides, iodine gas
Unusual Fire Hazards: Substance does not burn readily, but decomposition products can be harmful
Personal Precautions: Use personal protective equipment including gloves, goggles, and mask, ensure adequate ventilation, avoid dust formation, prevent contact with skin and eyes
Environmental Precautions: Prevent further leakage or spillage, avoid release to environment, keep away from drains or water sources
Cleanup Methods: Sweep up spill using inert tools, avoid raising dust, place material in proper waste container for disposal, decontaminate spill area with water after collection
Disposal: Follow disposal advice in local regulations, label containers properly
Precautions for Safe Handling: Avoid creating dust, wear recommended PPE, do not eat or drink during handling, wash hands after use
Hygiene Practices: Keep away from food and drinks, remove contaminated clothing after work
