How to clean PFAS AFFF from a firefighting foam tank

>> YOUR LINK HERE: ___ http://youtube.com/watch?v=jNoDFsd4RnY

When transitioning from AFFF to fluorine free foam, you need to make sure that no PFAS from the old foam concentrate contaminates the new foam concentrate. This video gives a detailed cleaning procedure for fire-fighting foam tanks. It considers the effectiveness of the cleaning and also the costs associated with it. • 0:00 Introduction • 2:09 The cleaning procedure • 3:49 The results • 5:22 Costs • There are actually two errors in the numbers: At 3:50 it should read 14,000ppb instead of 1,400ppb for PFOS in the old foam concentrate in appliance 2 and at 4:40 it should read 56ppb instead of 55ppb for for 4H-PFOS. Sorry for that, but I think it does not change the meaning of this video and the cleaning procedure. • https://epfire.de/en • Music: Stardust (Ziggy is coming) by Kraftamt http://ccmixter.org/files/Karstenholy... 2020 - Licensed under Creative Commons Attribution Noncommercial (3.0)
