  1. The request of modern fire fighting foams-between performance and responibility- Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG Liebigstr. 5 22113 Hamburg Dr. Rosvita Milo-Rieks

  3. Why AFFF/FFFP-Foam Concentrate ? • AFFF- and FFFP-Foam Concentrates • Fastest and most effective way for extinguishing big fires of hydrocarbons • Safety for Fire Fighters • Protection of life and property Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG

  4. Foam Application - MBS: Extinguishing performance classIIIC - AFFF/FFFP: Extinguishing performance classIB - Extinguishing time and burnback better withAFFF/FFFP - DIN 14493-100: Factors(>60% more) Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG

  5. Properties of the Aqueous Film The aqueous film is responsible for the following effects, which promote a fast and safe extinguishing: - cooling of solids and liquids - fast spreading of the foam blanket - stable barrier against evaporation of hydrocarbons - self-healing of the aqueous layer, if disrupted Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG

  6. Use of Perfluorinated Chemicals Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG

  7. PT chemical: Persistent Half life of up to 2000 years in the nature Toxic Hepartotoxic (liver), teratogen AFFF -Foam concentrates from Dr. Sthamer contains PFOA only in trace levels. PFOS PFOA PBT chemical: Persistent Half life of up to 2000 years in the nature Bioaccumulating Accumulates in proteins Half life 3-7 years in human body Toxic Hepartotoxic (liver), teratogen BT only with high dosage EPA: „current situation not an imminent health risk“ BT only with high dosage EU: PFOS-based foam agents removed until June 27, 2011 Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG

  9. Foam Concentrate Producers Producers of AFFF- and FFFP-foam concentrates :  Replacement of PFOS-based fluorosurfactants by telomer-based fluorosurfactants, if not already used  Advantage of telomer based Fluorosurfactants:  Fluorine part approximately 30-60% smaller than with PFOS without changing the performance  no PFOS during the production, as reaction aid, as by-product or waste Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG

  10. AFFF/FFFP and the Future  momentarily, there is no substitute for fluorosurfactants and there won‘t be a substitute in the near future  AFFF and FFFP will further be produced, as there is no substitute  But telomer fluorosurfactants are also persistent:  Looking for substitutes for fluorosurfactants  Looking for readily bio-degradable fluorosurfactants  Reducing the amount of fluorosurfactants, but without reducing the safety of the products Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co.
