Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.

  1. 1. TELOMER FLUOROSURFACTANTS
  2. 2. Background… In May 2000, 3M unexpectedly announced it was withdrawing from the manufacture of Light Water AFFF’s AFFF = Aqueous Film Forming Foam
  3. 3. Background… Research had shown that the 3M fluorosurfactant used in Light Water Foams had an environmental concern…
  4. 4. Background… They were known to degrade in the environment to: ● PFOS Perfluorooctyl sulfonate ● PFOA Perfluorooctanoic acid
  5. 5. Background… & are: ● Bioaccumulative ● PFOS ● Persistent ● Toxic ● PFOA
  6. 6. Background… Unlike 3M, almost all foam manufacturers use a process of telomerization which produces a telomer-based fluorosurfactant
  7. 7. Background… It is known that Telomer-based fluorosurfactants do not contain PFOS It is not known if they degrade into PFOA
  8. 8. Background… If they do degrade into PFOA, they too would be classed as ● Bioaccumulative ● Persistent ● Toxic
  9. 9. Telomer Research… In 2003, an EPA Work Group concluded: Telomer-based AFFF agents ● are not made with PFOA ● contain no PFOA-based product
  10. 10. Telomer Research… PFOA is an eight carbon molecule (C8) Most telomer-based flurosurfactants are derived from six carbon molecules (C6)
  11. 11. Telomer Research… The EPA Work Group concluded: There is no known pathway for C6 flurosurfactants to break down into PFOA
  12. 12. Telomer Research… However… This was considered to be incomplete research, as: ● some telomer molecules with a carbon chain greater than C6 are currently used in some AFFF’s
  13. 13. International Legislation… In Europe : ● the manufacture of PFOSbased Foams is now prohibited ● any remaining stock is to be removed from use by June 2011
  14. 14. International Legislation… In Europe : ● the EU is committed in the future to assessing substitutes to PFOS-based foams including telomer-based foams
  15. 15. International Legislation… However : as telomer-based foams do not contain PFOS no restriction is placed on their continued use
  16. 16. Buncefield Disaster Hertfordshire Oil Storage Terminal 11th December 2005
  17. 17. International Legislation… In the USA, Fluorotelomer & fluorosurfactant manufacturers are required: ● by 2010 to reduce by 95% emissions & product content of ● PFOA ● chemicals that can degrade to PFOA
  18. 18. International Legislation… In the USA, Fluorotelomer & fluorosurfactant manufacturers are required: ● by 2015 to achieve elimination of production of ● PFOA ● chemicals that can degrade to PFOA
  19. 19. C6 & environmentally friendly The move to fluorosurfactants As mentioned, Fluorotelomer & fluorosurfactant manufacturers in the USA are committed to remove ● all chemicals containing PFOA ● all chemicals that can degrade to PFOA
  20. 20. C6 & environmentally friendly The move to fluorosurfactants As a result, Telomer molecules with a carbon chain greater than C6 will effectively no longer be available for use
  21. 21. C6 & environmentally friendly The move to fluorosurfactants As discussed, research to date has concluded: There is no known pathway for C6 flurosurfactants to break down into PFOA
  22. 22. C6 & environmentally friendly The move to fluorosurfactants Accordingly, the way is now clear for foam manufacturers to begin developing AFFF’s with C6 fluorosurfactant telomer molecules
  23. 23. Conclusion: What does the future hold ?
  24. 24. The future : Requalifications Foam Manufacturers, including Oil Technics, are researching & developing C6-based AFFF formulations
  25. 25. The future : Requalifications These new formulations must meet International Standards: ● UL 162 ● EN 1568 ● ICAO Level B ● MIL-F 24385F
  26. 26. The future : Requalifications It is expected that the new foams will require to be requalified for these International Standards:
  27. 27. The future : Requalifications Achieving the International Standards assures users that the new C6 foams are as effective as existing Fire Fighting Foams
  28. 28. The future : Protein Foams Currently, C6 telomers for certain Protein Foam formulations have not been developed … yet !
  29. 29. The future : Foam Training & System Calibration Current recommendations remain: use Fluorine Free Mimic / Training Foam for ● Onshore Training ● System Calibration
  30. 30. The future : … are you ?
  31. 31. Thanks for listening … any questions ?
