First Aid Measures

Inhalation: Remove from exposure, bring to fresh air, call medical services if symptoms persist, monitor for respiratory distress
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek medical advice if irritation develops
Eye Contact: Rinse cautiously with water for at least 15 minutes, lift eyelids, seek prompt medical attention
Ingestion: Seek immediate medical attention, do not induce vomiting unless directed by medical personnel

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder
Unsuitable Media: Avoid direct water stream, may spread fire
Hazards: Gives off toxic fumes including hydrogen bromide, carbon monoxide in a fire
Protection for Firefighters: Full protective clothing, self-contained breathing apparatus

Accidental Release Measures

Personal Precautions: Evacuate area, use personal protective equipment, ensure ventilation
Environmental Precautions: Contain spillage to prevent entry into drains or waterways
Methods for Cleanup: Absorb with inert material (sand, soil), collect in chemical waste container, ventilate area and wash residual contamination, dispose in accordance with regulations

Handling and Storage

Safe Handling: Use explosion-proof equipment, ground containers, avoid inhaling vapors, avoid contact with eyes, skin, clothing
Safe Storage: Store in tightly-closed containers, cool, well-ventilated area away from sources of ignition, segregate from strong oxidizers and acids, keep out of reach of unauthorized personnel

Exposure Controls and Personal Protection

Exposure Limits: No established ACGIH or OSHA limits; handle as hazardous chemical
Engineering Controls: Fume hood ventilation, explosion-proof exhaust
Personal Protective Equipment: Chemical splash goggles, compatible gloves (nitrile or neoprene), lab coat, flame-resistant clothing if large quantities, use suitable respiratory protection if exposure risk exceeds safe levels or proper ventilation is not available

Ecological Information

Ecotoxicity: Harmful to aquatic organisms, may cause long-term adverse effects in aquatic environments
Persistence and Degradability: Low to moderate persistence, not readily biodegradable
Bioaccumulative Potential: High potential for bioaccumulation due to high log Kow
Mobility in Soil: Low due to hydrophobic character
Other Adverse Effects: Avoid release to the environment; absence of detailed ecological studies demands extra caution
