I was in my garage welding a patch on my 66. the window was out of the door and I had an old blanket hanging there to stop "debris" from getting inside. As I was welding, I thought I heard thunderous rain on the roof so I stopped and flipped my visor up to see not only the blanket in flames, but the headliner in the car as well!!!
got some pretty good burns to my wrists (not covered by gloves) putting that fire out.
I don't know if that's as bad as when I was welding under my old Isuzu pickup and I caught the gas tank on fire (those old Isuzu tanks always leaked)... at least that was outside!
I remember sitting there wondering if I should get the hose, or just let it go... I got the hose, because it was too close to the garage...
I have an industrial fire extinguisher now. lol
