Inhalation: Remove victim to fresh air immediately. Support breathing as needed. Seek medical attention for continued symptoms.
Ingestion: Rinse mouth, do not induce vomiting. Drink water if conscious. Seek immediate medical care.
Skin Contact: Remove contaminated clothing. Wash skin with soap and plenty of water for 15 minutes. Seek medical attention if irritation persists.
Eye Contact: Rinse thoroughly with water for several minutes. Remove contact lenses if possible. Get medical support if irritation continues.
Note for Medical Providers: Provide symptomatic treatment. Compound primarily risks irritation and potential systemic toxicity.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, or foam recommended. Use water spray to cool surroundings.
Specific Hazards: Produces toxic bromine compounds and nitrogen oxides under fire. Hazardous organic fumes likely.
Protective Equipment: Firefighters need self-contained breathing apparatus and full-body chemical protective gear.
Special Procedures: Evacuate area. Fight fire from protected location. Prevent contaminated water runoff from reaching environment.
Personal Precautions: Evacuate area, ventilate as much as possible, wear chemical splash goggles and gloves.
Environmental Precautions: Prevent material from entering sewers and drains. Extremely harmful to aquatic organisms even at low concentrations.
Containment Methods: Use inert absorbents such as sand or vermiculite. Scoop into suitable chemical waste containers.
Clean-up Procedures: Wash spill area with plenty of water and detergent. Dispose cleanup materials in compliance with local, state, and federal guidelines.
Handling: Use in well-ventilated areas only. Avoid breathing dust or fumes. Prevent skin and eye contact. Practice standard laboratory hygiene.
Storage Conditions: Store in tightly closed original containers, in a cool, dry, well-ventilated location. Isolate from strong oxidizers and acids.
Incompatible Materials: Strong oxidizing agents, strong acids, and reducing agents. Avoid moisture and sunlight exposure.
Other Precautions: Keep away from food, beverages, and incompatible chemicals.
Engineering Controls: Work in fume hood or local exhaust system. Minimize dust generation.
Personal Protective Equipment: Safety goggles, chemical-resistant gloves (nitrile or neoprene), lab coat, closed-toed shoes.
Respiratory Protection: Use NIOSH/MSHA approved respirators if exposure limits are exceeded or ventilation is insufficient.
Hygiene Measures: Wash hands thoroughly after handling and before eating or drinking. Segregate contaminated clothing for cleaning.
