Pentadecafluorooctanoic Acid CAS 335-67-1

1. Pentadecafluorooctanoic acid (PFOA) CAS 335-67-1 has been historically used as a surfactant and processing aid in the production of fluoropolymers like PTFE (Teflon).
2. Due to its environmental and health impacts,Pentadecafluorooctanoic acid use is now heavily restricted; primary applications are in critical industrial processes with no alternatives, often under regulatory authorization.
3. Current use is largely limited to closed-loop systems or as a trace impurity, with ongoing focus on environmental remediation and analysis of legacy contamination.

1. Store PFOA in a tightly sealed, chemically resistant container, in a secure, well-ventilated area designated for persistent and toxic substances.
2. Keep Pentadecafluorooctanoic acid strictly separate from food, feed, and incompatible materials. Ensure secondary containment to prevent environmental release.
3. Handle with extreme caution using full personal protective equipment (PPE): chemical-resistant gloves, goggles, face shield, and appropriate respiratory protection. Use only in a certified fume hood or equivalent containment.

1. Immediately isolate the area, prevent access, and alert specialized hazardous materials personnel. Do not attempt cleanup without proper training and equipment.
2. Contain Pentadecafluorooctanoic acid the spill using inert, absorbent material compatible with strong acids. Place all contaminated material in sealed, labeled containers for disposal as hazardous/POPs waste.
3. Prevent **any** release into the environment (air, water, soil). Decontamination must be thorough and conducted by professionals following strict regulatory protocols for persistent organic pollutants.

1. PFOA is **highly toxic**, causing severe organ damage (liver, kidney), developmental and reproductive toxicity, and is a suspected human carcinogen. It is persistent, bioaccumulative, and an extreme environmental hazard.
2. Pentadecafluorooctanoic acid is non-flammable but may emit highly toxic and corrosive fumes (hydrogen fluoride, carbon oxides) when heated to decomposition.
3. **Always consult the official PFOA Safety Data Sheet (SDS) and adhere to all national and international regulations (e.g., Stockholm Convention, REACH).** Its handling, use, and disposal are subject to severe legal restrictions.
