EC Number: 203-850-7
Molecular Weight: 165.08 g/mol
Inhalation: Remove person to fresh air and keep at rest. Seek medical attention if symptoms persist. If not breathing, provide artificial respiration.
Skin Contact: Remove contaminated clothing and shoes. Wash exposed skin with plenty of soap and water. Get medical advice if irritation appears.
Eye Contact: Rinse gently with water for at least 15 minutes, lifting eyelids occasionally. Remove contact lenses if present and safe to do so.
Ingestion: Do not induce vomiting. Rinse mouth with water. Seek immediate medical attention.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide. Do not use water jets directly on burning liquid.
Specific Hazards: Vapors may cause flash fires. Containers can burst in heat. Combustion may create corrosive and toxic bromine compounds.
Protective Equipment: Wear full self-contained breathing apparatus and protective clothing. Evacuate unnecessary personnel.
Firefighting Advice: Move containers from fire area if this can be done safely. Cool containers with water spray from a protected location to prevent rupture.
Personal Precautions: Evacuate area, ventilate space well, avoid breathing vapor. Wear suitable personal protective equipment including splash goggles, gloves, and a lab coat or protective coverall.
Environmental Precautions: Prevent entry into waterways, sewers, or confined zones.
Cleanup Procedures: Absorb spill with inert material like sand, earth, or vermiculite, then place in a chemical waste container. Wash area after removal. Dispose according to local regulations.
Safe Handling: Keep container tightly closed in a well-ventilated place. Use with local exhaust ventilation. Handle away from ignition sources and static discharge. Avoid contact with skin, eyes, and clothing.
Storage Conditions: Store in a cool, dry, properly labelled container away from incompatible substances like oxidizers or acids. Maintain temperature controlled environment, prevent exposure to direct sunlight and moisture.
Engineering Controls: Use fume hood or well-ventilated workspace. Maintain eyewash and safety shower near handling area.
Personal Protection: Wear chemical-resistant gloves (such as nitrile), splash-proof goggles, lab coat, and, if substantial vapor risk is present, a respirator with organic vapor cartridge.
Exposure Limits: No specific OSHA or ACGIH exposure limits established. Minimize exposure through proper engineering and hygiene practices.
Work Hygiene Practices: Wash hands after handling, before breaks, and at end of shifts. Remove contaminated clothing and launder before reuse.

Carcinogenicity: Not classified by IARC, NTP, OSHA.
Other Effects: May cause central nervous system depression if ingested in quantity.
Ecotoxicity: Harmful to aquatic life. Possibility of long-lasting effects given persistence and bioaccumulation.
Persistence and Degradability: Limited degradation in environment, tends to persist in soil and water.
Bioaccumulative Potential: Moderately bioaccumulative, log Kow above 3.
Mobility in Soil: Low mobility owing to hydrophobic nature.
Other Adverse Effects: Avoid release to environment. Toxic to aquatic organisms even at low concentrations.
Waste Treatment Methods: Collect waste in suitable containers, label clearly, and deliver to a licensed hazardous waste disposal contractor.
Incineration: Suitable for high-temperature incineration.
Container Disposal: Triple-rinse, puncture, and dispose by approved methods. Containers may retain residues; treat empty containers with same precaution as substance.
