I am extremely suspect that they were able to remove the bias for cancer from turnout gear. These guys daily job normalizes breathing in of cancer giving dust. They disproportionately smoke because it lessens the effect of having to work in a burned out area.
I hope they have a good non-cancer giving candidate to replace the PFAs. As long as the new garments underperform the old garments they will find ways to get a hold of the old garments.
