. . . arcs and smoke can be intimidating. Just the surprise from an arc can make you jump in an unpredictable way and if not hurt yourself from the electrical shock, then you'll bang your head or something else. . . In a previous life, I was reaching way to the back of a cabinet of radar equipment for some reason. I was lying on my stomach, my arm was extended all the way, and my head was into the cabinet doorway about at the forehead level, with a couple of inches clearance above and below. Of course all the safety precautions were followed -- some of the heavy ground radar stuff I worked on was easily lethal. But there was some charged capacitor, something hot from another cabinet of gear, I don't recall, and I got a minor shock. My instinctive reaction was to jerk my head up, and it hit the top of the doorway. That hurt and made me reflexively jerk my head downward, hitting the bottom of the doorway with my forehead. That caused a jerk back upward, hitting the top again, and so forth. There I was, oscillating up and down, beating my head to a pulp, knowing exactly what was happening but helpless to do anything about it. It continued for what seemed like a long time, until I was sore enough that I couldn't feel one more whack, when I was finally able to stop and extract my head and arm. I guess I've felt as stupid a few times since, but only a few times. And when you bend your arm every which way in order to get at something, it might go in all twisted contorted, but it comes out fast and straight when you get bit. I've lost a bit of skin that way, too. Roy Lewallen, W7EL |
