while this is true, with just handling these devices between parts bin, it's
still relative, once these are embedded in equipment and installed in a
facility, however remote, deep in a navy submarine or atop a mountain
observatory. You still needed to follow static precautions as far back when
digital logic was first used because the level of static discharge can
potentially increase when in presence of the various building materials in
and around the computer equipment.
