Specific Hazards: Under fire, toxic and corrosive fumes of bromide and nitrogen oxides may form
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full chemical protective clothing
Advice for Firefighters: Avoid inhaling fumes, evacuate area, control runoff to prevent environmental contamination, use standard fire-fighting protocols for chemical incidents
Personal Precautions: Wear suitable protective equipment including gloves, goggles, and laboratory coat, avoid generating dust
Environmental Precautions: Prevent entry into drains, water sources, or soil, contain spills using absorbent inert material
Containment and Cleanup: Scoop up solid or absorb with inert material, place in airtight container for disposal, ventilate contaminated area after removal, clean hard surfaces with water
Handling: Handle in well-ventilated area, avoid contact with skin and eyes, avoid dust formation, never eat, drink, or smoke during use, wash hands before breaks and at end of work
Storage: Store in tightly closed containers, cool and dry environment, protect from moisture and incompatible materials, segregate from strong oxidizers and acids, label storage clearly
Exposure Limits: No ACGIH or OSHA exposure limits published, minimize airborne dust
Engineering Controls: Use chemical fume hood or local exhaust, laboratory-standard ventilation
