Special Hazards: Combustion may release toxic fumes, including nitrogen oxides, carbon oxides, hydrogen bromide or bromine compounds.
Protective Equipment: Firefighters should wear full turnout gear and self-contained breathing apparatus due to risk of inhaling hazardous decomposition products.
Advice for Firefighters: Cool containers with water spray, prevent spillage and runoff into drains or watercourses if safe.
Personal Precautions: Evacuate area, ventilate and minimize dust generation, use protective gear including gloves, goggles, and dust mask.
Environmental Precautions: Prevent entry into waterways, sewers, basements; stop leak if safe.
Methods for Cleaning Up: Sweep up and shovel, avoid creating dust, collect in suitable closed containers for proper disposal, wash area with water and detergent to remove traces.
Other Notes: Dispose of all contaminated materials per local regulations to minimize environmental impact.
Handling: Use in well-ventilated areas, minimize exposure by wearing protective clothing and gloves, avoid contact with skin, eyes, and clothing, do not breathe dust.
Storage: Store in tightly closed container, keep in dry, cool, and well-ventilated place, avoid sources of ignition and incompatibles such as strong oxidizers.
Compatible Materials: Store away from oxidizing agents and acids.
Conditions to Avoid: Excessive heat, humidity, and direct sunlight disrupt stability and accelerate decomposition.
Exposure Limits: Occupational exposure limits not specifically established for this compound, but standard limits for nuisance dust apply.
Engineering Controls: Use local exhaust ventilation or process enclosures to control airborne concentrations.
Personal Protective Equipment: Safety goggles, chemical resistant gloves, long sleeves, appropriate respiratory protection where dust or aerosols are generated.
