Special Hazards: May emit toxic fumes including nitrogen oxides (NOx), hydrogen bromide, and carbon monoxide.
Protective Equipment: Wear full firefighting protective gear and self-contained breathing apparatus (SCBA).
Advice for Firefighters: Approach from upwind. Cool nearby containers with water spray to prevent bursting. Move undamaged containers from fire area if safe. Prevent fire control water runoff from entering sewers.
Personal Precautions: Evacuate unnecessary personnel. Wear appropriate personal protective equipment including gloves, eye protection, and a fitted respirator for dust.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, surface water, or soil.
Containment Methods: Sweep up spills using non-sparking tools. Avoid creating dust. Collect spilled material in a sealable, labeled container for disposal.
Cleanup Procedures: Wash contaminated area with soap and water. Ventilate room to remove dust and vapors. Dispose of waste following local, national, and international regulations.
Decontamination: Use absorbent materials for solution spills, followed by thorough cleaning.
Handling: Handle with care in a well-ventilated workspace. Minimize dust generation and accumulation. Wash hands after use. Do not eat, drink, or smoke near product.
Equipment: Use appropriate local exhaust ventilation. Use only tools made from materials compatible with organobromides.
Storage: Keep container tightly closed in a cool, dry, and well-ventilated place. Store away from incompatible substances such as strong oxidizers, acids, and reducing agents. Protect from moisture and sunlight. Store in labeled, corrosion-resistant containers.
Incompatibilities: Avoid storing near combustible materials and sources of ignition.
Occupational Exposure Limits: No OSHA or ACGIH exposure limits have been established for this material.
Engineering Controls: Provide local exhaust or general room ventilation to keep airborne levels low.
Personal Protection:
- Respiratory Protection: Use approved particulate respirators if ventilation is inadequate.
- Hand Protection: Chemical-resistant gloves (nitrile, neoprene).
- Eye Protection: Chemical safety goggles or face shield.
- Skin and Body Protection: Laboratory coat or apron, long-sleeved clothing.
- Hygiene Measures: Wash hands, forearms, and face thoroughly after handling. Remove contaminated clothing and wash before reuse.
