First Aid Measures

Inhalation: Remove person to fresh air promptly, keep at rest, provide medical attention if symptoms like coughing, breathing problems, dizziness persist
Skin Contact: Wash skin thoroughly with soap and water, remove contaminated clothing, seek medical advice if irritation develops or persists
Eye Contact: Flush eyes with plenty of water for several minutes, hold eyelids apart, remove contact lenses if present and easy to do, consult eye care professional if irritation continues
Ingestion: Rinse mouth with water without inducing vomiting, seek immediate medical attention for guidance on treatment, do not give anything by mouth to an unconscious person

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray (for larger fires)
Unsuitable Extinguishing Media: High-pressure water jets may spread the burning liquid
Specific Hazards: Vapors can form explosive mixtures with air, releases toxic fumes of hydrogen bromide and carbon oxides when burning
Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus to prevent inhalation of combustion products
Special Firefighting Procedures: Cool containers with water spray, prevent runoff from reaching drains or waterways, evacuate area in case of large spills or fire

Accidental Release Measures

Personal Precautions: Evacuate area if necessary, provide adequate ventilation, use gloves and splash goggles, avoid direct skin and eye contact
Environmental Precautions: Prevent spread to drains, soil, and natural waterways using sand or earth barriers, alert authorities if significant quantities enter environment
Methods for Clean-Up: Absorb spills with non-combustible absorbent material like vermiculite, sweep or shovel and place in labeled containers for disposal, wash residue with detergent solution followed by rinsing

Handling and Storage

Safe Handling: Work in chemical fume hood or well-ventilated area, avoid breathing vapors, keep container tightly closed when not in use, do not eat or smoke during use, handle away from sources of ignition
Hygiene Measures: Wash hands and exposed skin after handling, remove contaminated clothing and protective equipment before entering public areas
Storage Conditions: Store in cool, dry location, away from incompatible substances such as strong oxidizing agents and acids, keep away from sunlight, keep unopened in original containers
Storage Incompatibilities: Separate from strong acids, bases, oxidizers to prevent hazardous reactions

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific regulatory exposure limits have been established, recommend minimizing exposure
Ventilation: Use local exhaust ventilation or chemical fume hood to control airborne vapors
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash goggles, laboratory coat, use of respirator recommended for poor ventilation- NIOSH approved organic vapor cartridges
Environmental Controls: Regular monitoring of airborne levels, spill control measures, sealed containers for waste

Stability and Reactivity

Chemical Stability: 1-Bromododecane keeps a stable profile under ambient conditions if stored properly and not mixed with incompatible substances

Conditions to Avoid: Prolonged exposure to stored heat and direct sunlight, elevated temperatures, contamination with strong acids or bases
Incompatible Materials: Oxidizing agents, reducing agents, strong alkalis, strong acids
Hazardous Decomposition Products: Hydrogen bromide, carbon monoxide, brominated organic compounds on thermal decomposition

Toxicological Information

Routes of Exposure: Absorbed through skin, inhaled vapors, ingested accidentally
Acute Toxicity: Oral LD50 (rat) estimated above 5000 mg/kg, signs include nausea, abdominal discomfort
Skin Irritation: Causes redness or mild dermatitis, especially with repeated contact
Eye Irritation: May produce stinging or discomfort, reversible after thorough rinsing
Chronic Effects: Prolonged skin exposure can worsen irritation, no evidence for carcinogenicity or mutagenicity at levels encountered in laboratory handling
Sensitization: Rare, isolated reports of allergic reactions on repeated contact
Additional Information: Adequate studies on reproductive toxicity and organ effects remain lacking, prudent handling helps minimize risk

Ecological Information

Acute Aquatic Toxicity: Exhibits high toxicity to aquatic organisms such as fish and invertebrates, expected harmful effects from even small accidental releases
Chronic Effects: Significant persistence in soil and water, slow to biodegrade due to long carbon chain and bromine presence
Bioaccumulation: High potential due to lipophilicity (log Kow nearly 7), may accumulate in aquatic organisms
Mobility in Soil: Low mobility, strongly adsorbed to organic matter, could contaminate groundwater if released in quantity
Other Adverse Effects: Brominated organics have secondary effects through breakdown products, careful management prevents environmental incidents

Disposal Considerations

Waste Handling: Collect and store all wastes, including soiled absorbents, in sealed, clearly labeled drums approved for halogenated organic liquids
Authorized Disposal: Send only to licensed chemical waste contractors familiar with hazardous organic halides
Disposal Methods: Incineration at high-temperature facilities with scrubbers for acidic gases, do not dump in drains, water bodies, fields, or with mixed municipal waste
Container Disposal: Triple rinse containers, puncture or destroy to prevent reuse, recycle or landfill following local environmental regulations
