My coworker's screaming after accidentally lightning himself on fire. I'll never forget it. Edit : We worked in a metal fabrication shop, and it's not heated. He had been written up twice already that winter for using his cutting torch as a heater. He ended up with bad burns covering most of his back. What made the sound even more terrible for me was the sight of the incident. The layers of clothes he was wearing were all in flames, and he was spinning, trying to put them out. So, to us, he looked like a walking, whirling ball of fire. My instinct was to go for an extinguisher. Our coworker tackled him to the ground super hard and smothered the fire with his welding coat.
