First Aid Measures

Eye Contact: Rinse gently with clean water for several minutes, remove contact lenses if present, continue rinsing, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash exposed skin with soap and water, seek medical advice for persistent irritation
Inhalation: Move person to fresh air, keep comfortable for breathing, get medical help if symptoms like cough or headache develop
Ingestion: Do not induce vomiting, rinse mouth with water, get medical assistance right away
Note to Physician: Treat symptomatically, monitor for chemical pneumonia after ingestion

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, CO2, alcohol-resistant foam; avoid direct water stream
Unsuitable Extinguishing Media: Water jet
Specific Hazards: Vapors may form explosive mixtures, emits hydrogen chloride and other toxic fumes when burned
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective gear
Special Instructions: Cool exposed containers with water spray, avoid inhaling products of combustion

Accidental Release Measures

Personal Precautions: Evacuate area, wear protective gloves, goggles, and respirator if vapor levels are high
Environmental Precautions: Prevent spillage into drains, surface waters, or soil
Clean-up Methods: Absorb spill with inert material (sand, earth), collect in tightly closed containers for disposal, ventilate area thoroughly
Additional Measures: Notify environmental authorities if larger release threatens waterways

Handling and Storage

Handling: Use with local exhaust ventilation, avoid inhaling vapors, wear protective clothing and gloves, keep away from heat and sources of ignition
Storage Conditions: Store in well-ventilated, cool areas away from direct sunlight and incompatible materials like strong oxidizers, keep container tightly closed
Special Requirements: Ground containers during transfer, segregate from food and feedstuffs, store only in originally labeled containers with secure sealing

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limits established specifically for 1-Chlorododecane
Engineering Controls: Mechanical ventilation, use process enclosures, minimize airborne concentrations
Personal Protective Equipment: Chemical-resistant gloves (nitrile, PVC), safety goggles with side shields, flame-resistant lab coat, use NIOSH-approved respirator if ventilation is inadequate
Hygiene Measures: Wash hands, arms, and face thoroughly after handling, remove contaminated clothing before re-entering public areas or eating

Ecological Information

Ecotoxicity: Harmful to aquatic life (acute toxicity data: LC50 [fish] estimated at 2–10 mg/L)
Persistence and Degradability: Biodegrades slowly in soil and aquatic environments; potential for bioaccumulation due to high log Kow value
Mobility in Soil: Low mobility, binds to sediment and soil particles
Bioaccumulative Potential: High, based on chemical structure and partition coefficient
Other Adverse Effects: Potential long-term adverse effects in the aquatic environment
