Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or alcohol-resistant foam for small fires; For larger fires involving containers, apply water spray or fog
Specific Hazards: Combustion or thermal decomposition releases toxic fumes including carbon oxides, sulfur oxides, silicon oxides, and hydrogen fluoride
Hazardous Combustion Products: Toxic and corrosive gases are likely, including silicon tetrafluoride and fluorinated organic compounds
Protective Equipment for Firefighters: Self-contained breathing apparatus in positive pressure mode; Wear full protective gear resistant to chemical splash and vapor
Firefighting Instructions: Approach fire from upwind, use shielding to protect from heat and chemical splashes; Cool adjacent containers with water spray to prevent rupture; Evacuate area if fire cannot be controlled
Personal Precautions: Evacuate unnecessary personnel; Ensure adequate ventilation; Use full personal protective equipment including chemical splash goggles, gloves, and protective clothing
Environmental Precautions: Prevent further leakage or spillage if safe; Do not let chemical enter drains, surface water, groundwater, or soil to minimize toxic impact
Containment and Cleaning: Absorb spills with inert, non-combustible material (such as dry sand or earth); Use non-sparking tools; Place in chemical waste disposal container; Rinse area thoroughly with water after clean-up
Notification: Report significant releases to local authorities; Trace the extent of contamination and document findings for future reference
Handling: Avoid inhaling vapors, dust, or mist; Prevent contact with skin, eyes, and clothing; Work only in a chemical fume hood or well-ventilated laboratory space; Wash hands and face thoroughly after handling
Storage Conditions: Store in a tightly closed original container; Keep in a cool, dry, well-ventilated place away from incompatible substances (strong acids, bases, oxidizing agents); Shield from moisture, direct sunlight, and temperature extremes
Materials Incompatible: Avoid storing with water, bases, or highly reactive chemicals; Separation from inorganic acids and strong oxidizers reduces accidental reaction risk
Specific Storage Advice: Label tins or containers clearly; Restrict access to authorized personnel; Prepare secondary containment to minimize spread in case of leaks
Engineering Controls: Use chemical fume hood, local exhaust, or other engineering controls to maintain airborne levels below recommended exposure limits
Personal Protective Equipment (PPE): Safety goggles or full-face shield, flame-resistant and chemical-resistant gloves (such as nitrile or neoprene), lab coat or apron, long pants, closed-toe shoes
Respiratory Protection: Approved respirator suitable for organic vapors and particulates if ventilation is inadequate; Fit tests and filter changes are vital
Hygiene Measures: Do not eat, drink, or smoke in chemical areas; Remove and wash contaminated clothing before reuse; Thorough hand and face washing after handling required
Exposure Limits/Thresholds: No established occupational exposure limit; Use general precautionary thresholds for heavily fluorinated and sulfonated organosilicon reagents
Appearance: Colorless to light yellow liquid or low-melting solid (check batch-specific details)
Odor: Unpleasant, irritating chemical odor
Melting Point/Freezing Point: Data not widely published; presumed low for such silicones
Boiling Point/Range: Not typical due to decomposition; check exact batch if needed
Flash Point: Not easily flammable but check for values under controlled laboratory data
Solubility: Not miscible with water, soluble in typical organic solvents (dichloromethane, acetonitrile)
Vapor Pressure: Likely low at room temperature
Density: Data relies on synthetic route and purity; nominal value in range of 1.4–1.6 g/cm3
Partition Coefficient (n-octanol/water): Not expected to partition strongly into water, favoring organic phase
pH: Acidic if hydrolyzed
Decomposition Temperature: Releases toxic gases at elevated temperature or when in contact with moisture
Chemical Stability: Stable under recommended storage and handling conditions; Hydrolyzes rapidly in presence of moisture
Reactivity: Reacts exothermically with water, alcohols, amines, strong bases; Generates heat and toxic fumes
Conditions to Avoid: Avoid humidity, exposure to air, direct sunlight, elevated temperature, and sources of ignition
Incompatible Materials: Water, strong acids and bases, oxidizing agents, reducing agents

Chronic Health Effects: Prolonged or repeated exposure could sensitize skin, lead to chronic respiratory conditions, or target organs
LD50/LC50: Not specifically established for this compound; toxicology inferred from similar perfluoroalkyl and organosilicon reagents
Other Toxic Effects: Possibility of sensitization or delayed pulmonary edema; Lack of thorough human studies on long-term impacts
Ecotoxicity: Expected to be hazardous for aquatic organisms due to fluorinated constituents; Avoid uncontrolled release into the environment
Persistence and Degradability: Contains perfluorinated groups that resist biological breakdown; Lingers in soil and sediment
Bioaccumulative Potential: High potential for accumulation in aquatic or terrestrial organisms because of persistence
Mobility in Soil: Low solubility in water; migration likely limited unless attached to organic particles or sediments
Additional Notes: Avoid unintentional release to watercourses or sewers; Compound properties echo broader concerns about perfluorinated chemicals and their environmental legacy
Waste Treatment Methods: Treat as hazardous chemical waste; Incinerate at permitted facility under controlled conditions with scrubbing for off-gas treatment
Unused Material Disposal: Containerize unused material and label for proper collection by licensed hazardous waste management company
Contaminated Packaging: Triple rinse containers; Decontaminated packaging may be landfilled as non-hazardous waste, but this step calls for documentation
