Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Specific Hazards: Container may rupture from gas generation under fire conditions; toxic fumes of nitrogen oxides and carbon oxides generated
Special Protective Equipment: Full protective clothing, self-contained breathing apparatus
Advice for Firefighters: Keep containers cool with water spray, prevent runoff from entering sewers, avoid inhaling combustion products
Personal Precautions: Evacuate area, ensure adequate ventilation, avoid breathing vapors or dust, use proper PPE such as gloves, goggles, and mask
Environmental Precautions: Prevent from entering drains, sewers, or streams; notify authorities if significant leakage occurs
Containment Methods: Absorb spills with on-inflammable absorbent material like sand or earth, collect in labeled containers
Cleanup Methods: Clean area thoroughly with water and detergent after removal of bulk, ventilate area
Handling Methods: Avoid contact with skin and eyes, do not eat, drink, or smoke when handling, use mechanical ventilation or exhaust to minimize exposure
Storage Requirements: Store in tightly closed original containers, dry, cool, well-ventilated location out of direct sunlight
Incompatible Materials: Store separate from acids, strong oxidizing agents
Special Precautions: Keep away from heat sources, ensure containers are clearly labeled, check regularly for leaks
Exposure Limits: No specific national occupational exposure limits listed for 1-Decylimidazole

Density: 0.92–0.96 g/cm³
Partition Coefficient (log Pow): Estimated 4.5–5 (suggesting moderate bioaccumulation potential)
Autoignition Temperature: Not determined
Viscosity: Oily, moderate viscosity
Chemical Stability: Stable under recommended storage and use conditions
Reactivity: No hazardous reactivity under normal temperatures and pressures
Hazardous Reactions: Contact with strong oxidizers can cause hazardous decomposition
Conditions to Avoid: Excessive heat, direct sunlight, freezing
Incompatible Materials: Strong acids, bases, oxidizing agents
Decomposition Products: Thermal decomposition releases nitrogen oxides, carbon monoxide, carbon dioxide
Possible Routes of Exposure: Skin contact, eye contact, inhalation, ingestion
Acute Toxicity: Limited data, low acute oral and dermal toxicity expected, LD50 (oral, rat) >2000 mg/kg
Skin Corrosion/Irritation: Causes skin drying and mild irritation
Serious Eye Damage/Irritation: Causes mild to moderate irritation, possible conjunctivitis with prolonged contact
Respiratory or Skin Sensitization: Data not available; sensitization unlikely based on chemical structure
Chronic Effects: Prolonged or repeated exposure may lead to dermatitis
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Mutagenicity: No data available
Reproductive Toxicity: No relevant data or known effects
Ecotoxicity: No acute aquatic toxicity data; structurally similar quaternary imidazoles show moderate toxicity toward aquatic organisms (expected EC50, fish >1 mg/L)
Persistence and Degradability: Partial biodegradation likely, but may persist in environment owing to alkyl chain
Bioaccumulative Potential: Potential for bioaccumulation based on estimated log Pow
Mobility in Soil: Low mobility in soil, binds to organic matter
