[Amps] blowing up CMOS

“Because of this, you must be constantly grounded by a wrist strap.”

When you get really serious about static control, you make the floor conductive and require all personnel to wear heel straps.
Standard procedure at HP microwave instrument production areas. Static damage costs real money.

REPLY:

This method is better than nothing, but is still not adequate.

As can be demonstrated with a static meter, your body is constantly
generating static, even when seated by simple movement of your arm and
legs and even by shifting a little in the seat. Because of this, you
must be constantly grounded by a wrist strap.
