Inhalation: Move person to fresh air, seek medical attention for persistent symptoms like shortness of breath, irritation, coughing.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soapy water. Get medical help for blistering or persistent redness.
Eye Contact: Flush eyes gently with running water for at least 15 minutes, lift eyelids to ensure rinsing beneath; medical exam for pain or vision change.
Ingestion: Rinse mouth; do not induce vomiting. Drink water if conscious. Immediate medical attention required.
Note to Physicians: Treat as an oxidant poisoning; monitor for methemoglobinemia and kidney function.
Suitable Extinguishing Media: Flood with large volumes of water, do not use dry chemicals or carbon dioxide on this oxidizing agent.
Unsuitable Extinguishing Media: Dry chemical powders, foam, carbon dioxide increase reactivity.
Hazardous Combustion Products: Emits toxic bromine fumes and magnesium oxides upon high heat.
Specific Hazards: Contact with combustibles enhances fire risk, may detonate in confined spaces.
Protective Equipment: Firefighters use full protective gear and self-contained breathing equipment; evacuate area.
Firefighting Instructions: Cool containers with water even after fire extinguished, keep away from drains and water supplies.
Personal Precautions: Evacuate unprotected persons, ventilate area, avoid contact with skin, eyes, and clothing.
Protective Equipment: Chemical-resistant gloves, splash goggles, face protection, lab coat or coveralls, appropriate respirator.
Cleanup: Use clean, spark-proof tools. Sweep up, collect in corrosion-resistant container, avoid dust generation. Flush spill area with water.
Environmental Precautions: Prevent run-off to public sewers and waterways.
Disposal: Dispose according to approved local, regional, and national guidelines, consult environmental agency if accidental release threatens water systems.
Handling: Handle under chemical fume hood or well-ventilated space, avoid dust and direct inhalation.
Hygiene: Wash hands after handling, remove contaminated clothing before leaving work area.
Storage Conditions: Store in dry, cool, non-combustible, corrosion-resistant container with tight-fitting lid.
Segregation: Keep away from heat, open flame, acids, reducing agents, organic materials, and combustibles.
