Another thing that many people do not recognise with the need for ESD
protection is that the damage is not necessarily going to appear
straight away. I'd like a dollar for every time somebody told me that
they have never taken any precautions and everything works fine, not
realising that they have maybe wiped years off the component
reliability. Every time your body zaps something it doesn't necessarily
blow but it sure does weaken things, maybe just a fraction but when
stressed in service that will all factor in to the ultimate life and
failure of the component.

Those things are fine to do, **if** you are grounded or touch a ground before resuming work touching the parts.
Simple movement of the arms while working can be dangerous as the fabric on your clothing rubs while you move.
Remember, we're talking about ESD damage resulting from a *few volts* of static
charge, not hundreds of volts or the kilovolts it takes to produce a little
spark.

Wow, Lyle. You sound like the nuns in parochial school. But Sister, I

floor (no rubber soles). Don't shuffle your feet - especially if a
carpeted area - and don't wiggle in your chair.
