As long as the humidity level in the room is high, meaning, if you can walk across a carpeted room dragging your feet behind you and finally touch ground without an observable static discharge, your safe. The only time problems occur, is in the winter when usually the humidity level is very low. Or possible in a heavely airconditioned area. When the air is dry I do the following. Before handling a sensitive mos device I'll touch ground with my finger before handling it. I limit the movement of my arms to prevent static charge. Also make sure that your not wearing a sweater, especially one made out of wool! I have handled cmos digital chips, ccd chips, along with a variety of small signal(especially sensitive) and power MOSFETS, and I've never blown one out! Maybe I've been lucky or maybe the precautions I take are valid, but nevertheless what I'm trying to say is that people usually over react to these devices. If I had to handle these devices on a daily basic, I certainly would obtain a wrist strap along with a conductive tabletop, but not to simply replace a transistor in a television set. I hope this helps, Mark Cravatts
