As usual, the second rule of laser safety is:
"Do not look into laser with remaining eye." This was meant as a joke, I suppose. Back during my university studies, I had a colleague who was eager to see and learn about everything very powerful - no matter what it was (OK he was not really brilliant...). Incidentally, he had an accident and he lost one eye a few years ago. We had some laser classes, and I remember the hair-raising moment when he looked eagerly into the exit window of a class 4 argon laser the teacher was about to fire up, to see the beautiful blue-green light ... JW A former client was, among other things, the owner of a metal fabrication shop, one of considerable modernity and high automation. They had lasers that could cut through 10 cm deck steel at a very rapid feed rate. One worker was curious whether the laser with which he was working was turned on at one point, and, unfortunately for him, foolishly ran his finger through the otherwise invisible beam, which neatly severed his finger and cauterized the amputation in 100 ms or so. I don't know whether they were able to reattach his finger at the local hospital. RE |
