Going Fluorine Free

The transition to fluorine free foams is currently not very easy. It would be totally irresponsible to suggest otherwise. The diligent engineer will be concerned that there is very little actual test data on which to base foam system designs for F

...

Fluorinated Surfactants

An introduction to Fluorinated surfactants. Surfactants are everywhere in our day to day life; shampoos, dish washing detergents, soap, toothpaste and laundry detergents are just some of the most common. These products use based on hydrocarbon sur

Fluorine Free and non-aspirated applications

Non-aspirating use of AFFF's has been with us since 1978 or even earlier. This provides us with a large body of peer reviewed data and actual fire fighting experience. The references below provide some idea of the testing that was carried out. The

...

Fluorinated Fire Fighting Foams - History

The first patent for AFFF and maybe fluoroprotein foams was by Tuve & Jablonski at the Naval Research Laboratory in the early 1960's. The Naval Research Laboratory has played a major role since then is extensively testing fire fighting foams for

...

Fluorine Free and AFFF - what changes

What is different from AFFF to fluorine free foam (F3)? While all AFFF's use essentially the same technology (some use it better than others) and were considered functionally similar, this is not true for F3 foams. It will probably take quite a fe

...

Fluorine Free Foam for Tank Protection

There is not much to say about F3 foams and tank protection. The fuel shedding properties of fluorinated surfactants are very important for a number of tank fire fighting methods. None of the major design standards (NFPA 11, AS 1940) allow the use of

...

The Fluorine Free Goal

Changing to Fluorine Free fire fighting foams. The fire fighting foams that we have used for more than 50 years contain fluorinated surfactants. It has long been known that these chemicals are extremely slow to break down once they are released in
