Tell them to snap them up!!!!!  Snapping is just as important as the
groundstraps, etc.  We stress it in our training program and the video for
ESD that we use (of course from IPC  :-} ) mentions the importance of
keeping the jackets closed.   We have made it a punishable offense, just
like the ground straps, etc. Keeping the jacket open will allow static
charge to build up, dependent upon clothing, on the front of the person,
and based on my experience, the front of a person is always closest to the
circuit board and thus has a greater chance of contacting the unit and
creating problems.  The use of the jacket does a great job of bleeding off
the charge from clothing, and eventually allowing it to dissipate via the
persons skin/ground strap.

TechNetters, in our PC assembly plant, we have people wearing static
dissipative coats, long ones down to the knees.  Some do not snap them
closed in front, and just let the coats hang or float.  I've told the
people in my department to snap the coats closed, at least 2 of the 5 or 6
snaps.  Am I doing the right thing?  What's been your experience?
Thanks...Lou Hart

Also, the floors are coated with static dissipative wax or, in some places,
are static dissipative tile.  And the people are good about wearing wrist
and heel straps.
