Chemical Name: 3-Bromoaniline
CAS Number: 591-19-5
Concentration: 97-100%
Impurities: Trace amounts of other haloanilines (less than 1%)
Inhalation: Move exposed person to fresh air immediately. Support breathing as needed. Seek medical attention for persistent discomfort, including respiratory irritation, coughing, or shortness of breath.
Skin Contact: Remove contaminated clothing and rinse skin with soap and plenty of water for at least 15 minutes. Get medical help if irritation develops or persists.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing for at least 15 minutes and get medical advice promptly.
Ingestion: Rinse mouth with water if victim is conscious. Do not give anything to an unconscious person. Seek medical attention without delay.
Symptoms: Irritation of skin, eyes, and respiratory tract, gastrointestinal upset, potential for allergic reactions in sensitized individuals.
Medical Attention: Symptomatic treatment required according to condition.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: Do not use strong water jet, which may spread fire.
Specific Hazards from Fire: Hazardous combustion products may include nitrogen oxides, hydrogen bromide, and carbon monoxide.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing to prevent exposure to toxic fumes.
Special Procedures: Use water spray to cool fire-exposed containers. Fight from safe distance and avoid inhaling combustion gases. Contain runoff water to prevent environmental contamination.
Personal Precautions: Wear chemical-resistant gloves, goggles, and protective clothing. Avoid inhalation of dust or vapors. Evacuate area if necessary.
Environmental Precautions: Prevent further leakage or spillage if it can be done without risk. Do not allow product to reach watercourses, sewers, or soil.
Containment: Cover spillage with inert absorbent (e.g., sand or vermiculite).
Clean-Up Methods: Scoop up absorbed material and place in appropriate closed container for disposal. Ventilate area and wash spill site after material pickup.
Handling: Work in a chemical fume hood. Use personal protective equipment as described above. Avoid contact with skin, eyes, and clothing. Do not breathe dust or vapor. Handle according to good industrial hygiene and safety procedures.
Storage: Store in a cool, dry, and well-ventilated place, away from sources of ignition and heat. Keep container tightly closed, labeled, and out of direct sunlight. Store separately from incompatible materials such as oxidizing agents and acids.
Other Precautions: Maintain appropriate spill control, eyewash stations, and emergency showers at the workplace.
Occupational Exposure Limits: Not established for this substance. Use recommended controls and personal protective equipment.
Engineering Controls: Use only under local exhaust ventilation or in a laboratory fume hood.
Respiratory Protection: Use NIOSH-approved respirators when exposure is possible.
Eye/Face Protection: Chemical safety goggles and face shield.
Skin Protection: Chemical-resistant gloves (nitrile, neoprene), protective lab coat, long pants, closed-toed shoes.
Hygiene Measures: Wash hands after handling. Remove contaminated clothing and clean before reuse.
