Most Important Symptoms: Burns, severe irritation, coughing, difficulty breathing
Medical Attention Notes: Immediate care is important; monitor airway, breathing, circulation; treat symptomatically
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide for nearby fires; do not use dry chemical on bromine itself
Unsuitable Media: Avoid using foam
Specific Hazards: Releases corrosive and toxic fumes, may react violently with metals and organic materials, risk of hazardous decomposition products
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective suit
Special Instructions: To reduce exposure, use water spray to cool containers exposed to flame, fight from a safe distance, evacuate downwind personnel
Personal Precautions: Evacuate unprotected and untrained people, do not touch spilled material, ventilate area
Protective Equipment: Wear chemical-resistant gloves, splash-proof goggles, respirator with acid gas cartridge
Environmental Precautions: Prevent entry into sewers, soil, or waterways
Containment: Stop leak if it is safe, use inert absorbent material for small spills, keep area isolated
Cleanup: Use shovels or chemical-resistant tools, place collected material into suitable containers for disposal, wash spill site with plenty of water after pickup
Safe Handling: Only use in fume hood or well-ventilated area, avoid direct contact, avoid breathing vapors, never mix with organic substances, keep away from heat sources
Storage Requirements: Store in tightly sealed, corrosion-resistant containers, keep in cool and dry place away from incompatible substances such as metals, ammonia, or organic matter
Incompatible Materials: Alkali metals, reducing agents, organic materials, powdered metals, ammonia compounds
Special Precautions: Secondary containment is recommended for bulk storage, always use nonmetallic tools
Exposure Limits: OSHA PEL: 0.1 ppm (ceiling), ACGIH TLV: 0.1 ppm (TWA), NIOSH REL: 0.1 ppm
Engineering Controls: Use chemical fume hood, local exhaust ventilation
