Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray
Unsuitable Media: Direct water jet may spread fire
Unusual Fire and Explosion Hazards: Vapors heavier than air; May travel to source of ignition and flash back; Combustion yields toxic fumes (hydrogen bromide, carbon monoxide, carbon dioxide)
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Advice for Firefighters: Stay upwind and out of low-lying areas; Cool containers with water spray to prevent pressure build-up and possible rupture; Avoid inhaling combustion products

Accidental Release Measures

Personal Precautions: Ventilate area; Evacuate unnecessary personnel; Use protective gloves, safety goggles, and chemical-resistant clothing
Environmental Precautions: Prevent product from entering drains, surface water or soil; Alert authorities if significant quantity enters environment
Containment Methods: Use inert absorbent material (sand, earth, vermiculite) to contain spill
Clean-Up Procedure: Collect absorbent, place in suitable sealed container for disposal according to regulations; Clean contaminated surface thoroughly
Decontamination: Wash area with water and detergent; Avoid creating aerosols during clean-up
Disposal of Waste: Dispose of according to local, national, and international regulations for halogenated organic chemicals

Handling and Storage

Handling: Avoid breathing vapors, direct contact with skin or eyes; Use only in a chemical fume hood or well-ventilated area; Do not ingest / Do not eat, drink, or smoke while handling
Hygiene Measures: Wash hands thoroughly after use; Remove and wash contaminated clothing before reuse
Storage: Store in tightly closed, properly labeled containers in a cool, dry, well-ventilated location, away from incompatible substances (strong oxidizing agents, strong bases); Protect from light and moisture
Incompatible Materials: Strong oxidizing materials, strong alkali, strong acids
Specific Storage Requirements: Segregate from sources of heat, sparks or open flame

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limit for 1,10-dibromodecane
