TELOMERFLUOROSURFACTANTS

Background…
In May 2000,3M unexpectedly announced it was withdrawing from the manufacture of Light Water AFFF’s
AFFF = Aqueous Film Forming Foam
![Page 3: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/3.jpg)
Background…
Research had shown that the 3M fluorosurfactant used in Light Water Foams had an environmental concern…

Background…
They were known to degrade in the environment to:
● PFOS
● PFOA
Perfluorooctyl sulfonate
Perfluorooctanoic acid

Background…
● PFOS
● PFOA
&
are:
● Bioaccumulative
● Persistent
● Toxic

Background…
Unlike 3M, almost all foam manufacturers use a process of telomerization
which produces a telomer-based fluorosurfactant
![Page 7: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/7.jpg)
Background…
It is known that
Telomer-based fluorosurfactants
do not contain PFOS
It is not known
if they degrade into
PFOA
![Page 8: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/8.jpg)
Background…
If they do degrade into PFOA,
they too would be classed as
● Bioaccumulative
● Persistent
● Toxic

Telomer Research…
In 2003, an EPA Work Group concluded:
Telomer-based AFFF agents
● are not made with PFOA
● contain no PFOA-based product
![Page 10: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/10.jpg)
Telomer Research…
PFOA is an eight carbon molecule (C8)
Most telomer-based flurosurfactants are derived fromsix carbon molecules (C6)
![Page 11: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/11.jpg)
Telomer Research…
There is no known pathwayfor C6 flurosurfactants to break down into PFOA
The EPA Work Group concluded:
![Page 12: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/12.jpg)
Telomer Research…
However…This was considered to beincomplete research
● some telomer molecules with a carbon chain greater than C6 are currently used in some AFFF’s
, as:

In Europe :
InternationalLegislation…
● the manufacture of PFOS- based Foams is now prohibited
● any remaining stock is to be removed from use by June 2011
![Page 14: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/14.jpg)
In Europe :
InternationalLegislation…
● the EU is committed in the future to assessing substitutes to PFOS-based foams
including telomer-based foams
![Page 15: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/15.jpg)
However :
InternationalLegislation…
as telomer-based foams do not contain PFOS
no restriction is placed on their continued use

In the USA, Fluorotelomer & fluorosurfactant manufacturers are required:
● by 2010
InternationalLegislation…
to reduce by 95%
emissions & product content of
● PFOA ● chemicals that can degrade to PFOA
![Page 18: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/18.jpg)
In the USA,
InternationalLegislation…
Fluorotelomer & fluorosurfactant manufacturers are required:
● by 2015to achieve eliminationof production of
● PFOA ● chemicals that can degrade to PFOA
![Page 19: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/19.jpg)
As mentioned,
The move to C6 &environmentally friendly
fluorosurfactants
Fluorotelomer & fluorosurfactant manufacturers in the USA are committed to remove
● all chemicals containing PFOA
● all chemicals that can degrade to PFOA
![Page 20: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/20.jpg)
As a result,
The move to C6 &environmentally friendly
fluorosurfactants
Telomer molecules with a carbon chain greater than C6
will effectively no longer be available for use
![Page 21: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/21.jpg)
The move to C6 &environmentally friendly
fluorosurfactantsAs discussed, research to date has concluded:
There is no known pathwayfor C6 flurosurfactants to break down into PFOA
![Page 22: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/22.jpg)
The move to C6 &environmentally friendly
fluorosurfactantsAccordingly, the way is now clear for foam manufacturers to begin developing AFFF’s
with C6 fluorosurfactant telomer molecules

Conclusion:
What does the future hold ?
![Page 24: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/24.jpg)
The future :Requalifications
Foam Manufacturers, including Oil Technics, are researching & developingC6-based AFFF formulations
![Page 25: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/25.jpg)
The future :Requalifications
These new formulations must meet International Standards:
● UL 162
● EN 1568
● ICAO Level B
● MIL-F 24385F
![Page 26: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/26.jpg)
The future :Requalifications
It is expected that the new foamswill require to be requalified for these International Standards:
![Page 27: Oil Technics Ltd: C6 Fire Fighting Foam Concentrates.](https://reader035.fdocuments.net/reader035/viewer/2022081511/55626854d8b42aab1a8b4da5/html5/thumbnails/27.jpg)
The future :Requalifications
Achieving theInternational Standardsassures users that the new C6 foams
are as effective as existing Fire Fighting Foams

The future :Protein Foams
Currently,
C6 telomers for certain Protein Foam formulations
have not been developed … yet !

The future :Foam Training
Current recommendations remain:
& System Calibration
use Fluorine Free Mimic / Training Foam for● Onshore Training● System Calibration
