It is true to say that most recent fears about foams have been related to PFOS. There are two distinct problems that must be considered. First of all, although PFOS foams are no longer manufactured many thousands of tonnes of super-concentrate are still available in the market place.
They will remain in the industry for at least the next 10 years or more. PFOS is classed as very persistent (vP) in the environment, it is bioaccumulative and toxic. All of this research information is documented.
Secondly, as a service engineering company you may not know what foam is contained in any particular unit of equipment and should treat all foams on a worst case basis. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
