Personal Precautions: Evacuate personnel, avoid breathing vapors, use full protective gear including gloves, goggles, and chemical-resistant clothing
Environmental Precautions: Prevent spillage from entering drains, soil, or waterways; inform local authorities if significant release occurs
Cleanup Methods: Absorb spill using inert dry material (e.g. sand, vermiculite), collect and seal in proper chemical waste containers, ventilate area, wash site after material pickup
Decontamination: Use suitable neutralizer for acids if needed, dispose of all cleanup materials as hazardous waste
Safe Handling: Handle in chemical fume hood with proper ventilation, avoid contact with skin, eyes, clothing; do not breathe vapor or mist; do not eat, drink or smoke in work area
Storage Conditions: Keep container tightly closed in dry, cool, and well-ventilated area, away from acids, bases, and incompatible materials; protect from moisture; segregate from oxidizers and moisture sources
Incompatible Materials: Water, strong oxidizers, strong bases, strong acids; may react violently
Storage Life: Monitor regularly for container integrity and substance quality
Exposure Limits: No specific regulatory limits established for this compound; minimize all exposure due to corrosive nature and unknown chronic toxicity
Engineering Controls: Local exhaust ventilation, fume hood recommended; process enclosures if handling outside laboratory
Personal Protective Equipment (PPE): Nitrile or butyl gloves, goggles or face shield, flame-resistant lab coat, chemical-resistant apron when handling larger volumes, respiratory protection if ventilation insufficient
Hygiene Measures: Wash hands, face and any exposed skin before breaks and after handling, remove contaminated clothing

Symptoms of Exposure: Severe burning, redness, pain, tissue damage, delayed respiratory symptoms
Toxicity: Harmful to aquatic organisms; exact EC50/LC50 values not available but based on chemical category and similar substances precaution urged
Persistence and Degradability: Degrades slowly in the environment, hydrolysis can yield persistent fluorinated acids
Bioaccumulative Potential: No clear evidence, possible moderate bioaccumulation due to fluorinated group if released to water
Mobility in Soil: Water-reactive, can leach after hydrolysis
Other Adverse Effects: Chemical may pose long-term hazards to aquatic life and must not be released to water bodies
Waste Disposal Method: Collect and place in labeled, tightly sealed hazardous waste container; incineration at approved facility strongly preferred; avoid disposal through drains, sewers, or natural environment
Contaminated Packaging: Dispose of as unused product; do not reuse containers; inspect thoroughly before disposal
Additional Precautions: Consult local, regional, national statutes, and regulatory authorities for most up-to-date requirements. Handlers must use personal protective equipment and avoid direct contact at all times during disposal operations
