Ouch thats pretty scary. I was welding in the floor pans on my brothers monte carlo SS and was under the car when i lit my hair on fire LOL. I had much longer hair back then. My niece cuts hair for a living. I asked her to please fix my lopsided head of hair.
The material didn't burn too fast so it wasn't that bad but, like I said, not having a sense of smell does cause some interesting situations from time to time.
