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.
