5. Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Hazards During Fire: Toxic bromine-containing gases and hydrogen bromide can form.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing.
Special Procedures: Move containers from fire area if you can do it without risk. Cool containers with flooding quantities of water until well after fire is out.

6. Accidental Release Measures

Personal Precautions: Keep unnecessary and unprotected personnel out of the area. Wear suitable respiratory protection, chemical-resistant gloves, safety goggles, and protective clothing.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not let the product enter drains, surface water, or ground water.
Containment and Cleaning: Ventilate area. Absorb with inert material such as sand or earth and collect in chemical waste container. Wash spill site after material pickup has been completed.

7. Handling and Storage

Handling: Avoid contact with skin, eyes, and clothing. Minimize generation of vapors or mists. Use only with adequate ventilation. Do not eat, drink, or smoke when using.
Storage: Store in tightly closed original container in a dry, cool, well-ventilated area, away from incompatible substances. Keep out of direct sunlight. Keep away from food and feedstuffs.

8. Exposure Controls and Personal Protection

Engineering Controls: Ensure adequate ventilation, especially in confined areas. Laboratory fume hood recommended.
Personal Protective Equipment: Safety goggles, lab coat, chemical-resistant gloves (nitrile or neoprene), appropriate protective clothing. In case of insufficient ventilation, wear suitable respiratory protection.
Hygiene Measures: Thoroughly wash hands and contaminated skin after handling. Remove contaminated clothing and wash before reuse.
Exposure Limits: No specific occupational exposure limits for this substance established by OSHA, ACGIH, or NIOSH.
