Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical assistance.
Important Symptoms: Irritation or burns to eyes and skin, respiratory tract irritation, upset stomach or vomiting if ingested
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: Avoid foam which may react with product
Special Hazards: Product decomposes to release toxic fumes including iodine, sodium oxides. Intensifies combustion of other materials.
Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus
Advice for Firefighters: Evacuate area, contain runoff, avoid inhalation of decomposition products.
Personal Precautions: Keep away from ignition sources. Ensure adequate ventilation. Avoid contact with skin and eyes.
Environmental Precautions: Prevent large amounts entering drains, sewers, or watercourses.
Methods for Clean-up: Use non-combustible absorbent, sweep up carefully, containerize for disposal. Wash area with plenty of water, ventilate space.
Emergency Procedures: Evacuate non-essential personnel, report significant spills to environmental authorities.
Handling: Avoid formation of dust, don't eat, drink or smoke when handling, use local exhaust, handle away from combustible material.
Storage: Store in tightly closed container, cool, dry, well-ventilated location separated from organic materials, reducing agents, acids.
Incompatible Materials: Reducing agents, organic substances, acids, combustibles, powdered metals.
Packaging: Use corrosion-resistant, non-combustible packaging with secure seals.
Occupational Exposure Limits: Not established specifically, minimize dust exposure, monitor for respirable particulates
Engineering Controls: Local exhaust ventilation, eye wash stations, safety showers
