Suitable Extinguishing Media: Dry chemical, foam, CO₂, water spray used for small fires
Unsuitable Extinguishing Media: Direct water stream may spread chemical
Fire Hazards: Product can emit hazardous fumes (nitrogen oxides, sulfur oxides, fluorine compounds, carbon oxides)
Protective Equipment: Firefighters need self-contained breathing apparatus, full chemical protection clothing
Special Procedures: Cool unaffected containers with water spray, keep safe distance, avoid inhaling fumes
Personal Precautions: Use personal protective equipment (gloves, safety goggles, lab coat, mask); avoid contact with skin and eyes
Environmental Precautions: Prevent further leakage or spillage if safe; avoid entering drains, surface water and soil
Cleanup Methods: Absorb with inert material (sand or vermiculite), scoop to labeled chemical waste container, ventilate area well
Spill Response: Report large spills to emergency services, seal area, ventilate and dispose of cleanup materials safely
Handling: Handle inside chemical fume hood or well-ventilated area; wear protective equipment; minimize aerosol and dust formation
Storage: Store in tightly sealed original container in cool, dry environment, away from moisture, oxidizing materials and sources of ignition
Incompatible Materials: Avoid contact with strong oxidizers, water, acids, and bases which may cause dangerous reactions
Other Recommendations: Ensure containers are clearly labeled; regular inspection for leaks or corrosion can reduce risks
Engineering Controls: Use with local exhaust ventilation, chemical fume hood, eye wash station, and safety shower
Respiratory Protection: Approved air-purifying respirator when ventilation is not sufficient
Hand Protection: Chemical-resistant gloves (nitrile or neoprene recommended)
Eye Protection: Splash-proof safety goggles or face shield
Skin Protection: Flame-retardant laboratory coat, long sleeves, enclosed shoes
Hygiene Measures: Do not eat, drink, or smoke while handling; wash hands and face thoroughly after working; remove contaminated clothing immediately
Appearance: Colorless to pale yellow liquid or crystalline solid (depends on temperature)
Odor: Faint, chemical
Melting Point: Ranges between 13°C and 18°C
Boiling Point: Decomposes before boiling

Vapor Pressure: Negligible at room temperature
pH: Neutral to slightly acidic in water
Reactivity: Stable under recommended handling and storage conditions; slow hydrolysis in moist air
Chemical Stability: Stable at ambient temperature; avoid moisture, strong acids and bases for best shelf life
Hazardous Reactions: Risk of violent reaction with strong oxidizers
Decomposition: Heat or fire causes release of toxic gases such as SOx, HF, and NOx
Incompatible Materials: Strong acids, strong bases, oxidizing agents
Acute Toxicity: Oral and dermal toxicity data limited, generally considered low to moderate hazard; may be harmful by ingestion
Skin Irritation: Causes irritation; repeated exposure increases risk of dermatitis
Eye Irritation: Causes eye irritation, temporary redness, tearing, blurred vision
Sensitization: No available data for respiratory or skin sensitization
Chronic Toxicity: Long-term effects unknown; avoid repeated or prolonged exposure
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No current evidence or regulatory listing as carcinogen or mutagen, reproductive toxicity data limited or unavailable
Aquatic Toxicity: Toxic to aquatic organisms at higher concentrations; may cause long-term adverse effects in the aquatic environment
Degradability: Low biodegradability expected, persistent in soil and water
Bioaccumulative Potential: Significant potential for bioconcentration not established
Mobility in Soil: Moderately mobile, risk of groundwater contamination after widespread spill
Other Adverse Effects: Fluorinated compounds can persist and accumulate, causing ecosystem concerns
Waste Disposal Methods: Dispose of contents/container at hazardous waste collection facility; incinerate only under controlled, permitted conditions
Container Disposal: Triple rinse empty containers before recycling or discarding; follow local, state, and national laws
Additional Information: Do not pour down drain; avoid release to environment
UN Number: Specific UN number not consistently assigned; confirm with logistics provider
Proper Shipping Name: Chemical name used as proper shipping name
