I think it still could happen with some nylon, polyesters or similar fabrics, burns and fuses to the skin.
All horrible. What was the saying, "Stop Drop and Roll?"

I believe it was a Christmas Eve dinner, and my mother had candles lit on the server. My one daughter who was about 7 or 8 who was directly across the table from me near the hostess seat and had medium-long straight hair that caught fire.
It happened so quickly most of us at the table didn't notice to react, but thanks to my Uncle Charles and before my daughter could panic, he immediately smothered the fire with his bare hands. Everyone registered shock after that. And awe at the actions of my uncle. And gratitude.
Something to warn girls (and anyone with long hair) about, haven't heard of an incident since the one with my daughter.
Dont forget to remind those of long hair to similarly exercise extreme caution when working around machinery and looking at the car engine while its running!
