A recent study done at North Carolina State University took a look at PFAS chemicals used in turnout gear and came to some interesting conclusions.

PFS layers are what give current turnout coats and pants their oil and water repellency.

They're also a known carcinogen, so donning PPE made with PFAS is dangerous even before you step onto your engine or truck.

Unfortunately, when the study looked at alternatives, it found that all oil repellents can also repel water, but all water repellents don’t necessarily repel oil.

My guest on this show is Bryan Ormond, an assistant professor of textile engineering, chemistry and science at NC State. He also wrote up the results of the study.
