Methods for Containment: Limit spread using dikes or absorbent material such as sand or earth
Methods for Cleanup: Collect spillage with inert absorbent, transfer to suitable waste containers, dispose of in accordance with local regulations
Decontamination: Wash residue with plenty of water; ventilate area after clean-up
Handling: Work in well-ventilated area; use tools and procedures to prevent static discharge; avoid direct contact with skin and eyes; do not eat, drink, or smoke while using
Storage: Store in tightly closed container made of compatible material; keep container in cool, dry, well-ventilated area, away from direct sunlight and sources of ignition
Incompatible Materials: Avoid storage with oxidizing agents, strong acids, strong bases

Decomposition Products: Releases phosphine, fluorinated hydrocarbons, sulfur oxides in fire or prolonged heating
Conditions to Avoid: Open flames, high temperature, exposure to incompatible chemicals, direct sunlight
Acute Toxicity: Oral LD50 and dermal LC50 not reported; limited data, expect low to moderate toxicity based on similar compounds
Skin Contact: Mild to moderate irritant; redness, dryness, possible minor dermatitis
Eye Contact: Irritant; may cause tearing, stinging, temporary vision disturbance
Inhalation: Vapors and dust unlikely but may irritate throat and respiratory tract
Chronic Effects: No evidence of carcinogenicity or mutagenicity found in available research
Target Organs: Skin, eyes, possibly respiratory tract in case of repeated or prolonged exposure
Sensitization: No reports of allergic sensitization from regular lab use
Aquatic Toxicity: Harmful to aquatic life based on structure-activity relationships of perfluorinated components
Persistence and Degradability: Perfluorinated sulfonates resist degradation; considered persistent in the environment
Bioaccumulation: Potential for bioaccumulation exists due to fluorinated tail; no measured bioconcentration factor available
Mobility in Soil: Water solubility and molecular weight suggest moderate mobility, especially under acidic conditions
Other Adverse Effects: Discharge to natural waters should be strictly limited; monitoring advised for industrial users
Methods of Disposal: Dispose through authorized chemical waste treatment facility; never discharge into drains or waterways
