Since ESD can occur by induction, you want to make sure visitors are grounded. Not be grounded and in proximity to machines or electronics can cause an ESD event to occur that causes the machine to shut down suddenly or permanently damages the electronics.When we go to handle electronics we want to make sure we are not electrically isolated, but instead electrically bonded (also known as ?being grounded?). This allows those static electrons to discharge from our clothes and skin to the ground beneath our feet. Wearing a heel grounder connected to an electrically bonded floor or floor mat is a common way to ?ground? large assembly lines.
