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

4. Foam Application - MBS: Extinguishing performance class IIIC
- AFFF/FFFP: Extinguishing performance class IB
- Extinguishing time and burnback better with AFFF/FFFP
- DIN : Factors (>60% more)

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

7. PFOS PFOA Persistent Bioaccumulating Toxic Persistent Toxic
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
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.
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

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

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
