Within firefighting there is an international move towards the ban of PFAS containing AFFF products. It has been shown through empirical testing that:
F3 is less effective in like-for-like foam systems
Different F3 manufacturers perform differently in like-for-like systems
F3 physical properties can be incompatible with certain equipment
F3 can outperform AFFF when system modifications are made
I have conducted much of this testing and can aid in your system design or modifications with my knowledge and experience, get in touch to find out more.
