Inhalation: Move person to fresh air immediately. Seek medical attention without delay. Provide oxygen or artificial respiration if breathing has stopped.
Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with water for at least 15 minutes. Seek immediate medical assistance.
Eye Contact: Rinse cautiously with water for several minutes, always keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing and contact a physician immediately.
Ingestion: Do not induce vomiting. Rinse mouth with water. Never give anything by mouth to an unconscious person. Get medical help at once.
Extinguishing Media: Dry chemical, carbon dioxide, or appropriate foam. Water spray may be used to cool containers but avoid water as jet.
Specific Hazards: Emits toxic fumes of hydrogen bromide and iodine under fire conditions. Strong oxidizer; supports combustion of other materials.
Protective Equipment: Full protective firefighting clothing including self-contained breathing apparatus. Avoid inhalation of combustion products.
Unusual Fire Hazards: Decomposition releases bromine and iodine vapors which are highly irritating.
Firefighting Procedures: Keep uninvolved people away, ventilate area, and fight fire from upwind.
Personal Precautions: Evacuate unnecessary personnel. Provide adequate ventilation. Wear suitable chemical-resistant gloves, goggles, chemically resistant clothing, and NIOSH approved respiratory protection.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not contaminate water, soil, or drains.
Clean-up Methods: Absorb with inert dry material such as sand or non-combustible absorbent. Collect in suitable containers for disposal. Thoroughly ventilate area and wash spill site.
Special Handling: Avoid dust generation. Minimize exposure to vapors or fumes.
Handling: Work with chemical fume hood or well-ventilated area. Wear full protective equipment. Avoid contact with skin, eyes, and clothing. Avoid inhalation of vapors or dust. Do not eat, drink, or smoke during use.
Storage: Store in a cool, dry, well-ventilated place, away from heat sources and incompatible materials such as bases, reducing agents, metals, and combustible materials. Keep container tightly closed and properly labeled. Store away from moisture and direct sunlight.
Exposure Limits: No established OSHA PEL or ACGIH TLV for Iodine Monobromide; control exposure to lowest achievable levels.
Engineering Controls: Use chemical fume hood, local exhaust ventilation, safety shower, and eyewash stations.
Personal Protective Equipment: Chemical splash goggles, face shield, gloves (nitrile, neoprene, or rubber), lab coat or chemical suit, suitable respiratory protection when airborne exposure risk exists.
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling, before breaks, and at end of process.
Environmental Controls: Prevent material from entering wastewater and natural waterways.
