Yeah, I noticed that too. He even mentioned the "silk tie". But, that poor guy that got the 3rd degree burns was probably wearing polyester. I'm pretty sure from "10 feet away" that would melt.

I saw a video a few years ago during CERT training. Showing a fire fighter that had not put on a shirt, but had his bunker gear with the suspenders over his shoulders. There was a flash fire/explosion. He suffered 1st and 2nd degree burns (lucky guy!) over his chest. Only where the suspenders had covered his skin was he not burnt.
