I was working with a large scale scientific computer in a temperature and humidity controlled environment (68F and 50%H). We were encountering quasi random errors which were (eventually) traced to coincide with console operations with a particular operator. There were no input errors on the key strokes!! We called in the local University's research department to try to help us. Even though we had anti-static mats, grounding tabs, and we were using carpets with a copper strand content, it was found that this particular operator would carry a charge of ~18KV when walking from the tape drives to the console. Big "zap" on the keyboard, microsecond duration... Long story made short -- The operator (female - no bias intended) was requested to refrain from wearing nylon/polyester clothing, she agreed and the problem was solved. Moral: If you are nor going to take anti-static precautions, then sit *very* still in your chair and don't shuffle your feet !!
