Firefighter Protection: Wear SCBA (self-contained breathing apparatus) and full protective gear
Special Procedures: Cool containers with water, move undamaged containers from fire area if safe to do so, prevent runoff from entering drains

6. Accidental Release Measures

Personal Precautions: Evacuate area, ventilate space, wear chemical-resistant gloves, lab coat, and goggles
Environmental Precautions: Prevent spill from entering waterways, sewers, or soil
Clean-Up Methods: Absorb spill with inert material like dry sand or vermiculite, place in chemical waste container, wash area with soap and water after clean-up
Disposal: Follow regulatory requirements for chemical waste (see section 13)

7. Handling and Storage

Handling: Work in a certified chemical fume hood, avoid inhalation and direct contact, avoid splashing and spillage, use only with appropriate PPE
Storage: Store in a tightly closed, amber-glass container; keep in a cool, dry, well-ventilated area; store away from incompatible materials such as strong oxidizers and bases
Specific Conditions: Protect from light, moisture, and sources of ignition
Hygiene Practices: Wash hands after handling, avoid eating, drinking, or smoking nearby

8. Exposure Controls and Personal Protection

Exposure Limits: No established OSHA/ACGIH limits for Β-Bromoethyl-Benzene; minimize exposure by engineering controls
Engineering Controls: Mechanical exhaust (fume hood), eyewash stations, safety showers
Personal Protective Equipment: Chemical splash goggles, lab coat, nitrile gloves, and respiratory protection if airborne concentration is high
Other Precautions: Do not wear contact lenses when handling this material; ensure all PPE is compatible with chemical

Other Data: Detailed toxicological profiles not fully established

12. Ecological Information

Aquatic Toxicity: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Not readily biodegradable, may persist in soil and water
Bioaccumulation Potential: Potential to bioaccumulate based on log Kow value
Mobility in Soil: Low to moderate mobility due to hydrophobic nature
Other Ecological Effects: Toxic to some aquatic invertebrates, limited data for terrestrial species

13. Disposal Considerations

Disposal Methods: Incinerate under controlled conditions using an approved chemical waste facility
Container Disposal: Decontaminate empty containers, puncture, and dispose of as hazardous waste
Precautionary Disposal Measures: Avoid release to the environment, follow all local, state, federal regulations for hazardous waste
Recommended Procedure: Consult with licensed hazardous waste disposal contractor for best disposal practices
