Subject: [TN] ESD Issue - non ESD Chairs on Manufacturing Floor

A sister company of ours has just undergone an ESD audit by one of their
customers. During the audit, they were cited for allowing non ESD chairs
(i.e. no drag chains and/or conductive wheels/legs) in the manufacturing
areas. I looked in IPC-A-610, in section 3.2 (ESD/EOS Safe Workstation)
and
find no reference to non-ESD chair use. Simply put, if a solder
operator,
assembler, etc. is seated in a non ESD chair, but wearing heel straps
(on a
dissipative floor) and is jumpered to a grounded jack via a wrist strap
my
take is that they are sufficiently grounded to perform their work. I
have
never had any external ESD audit fail for this reason.

Anyone else have any experience with this type of call? I don't have a
copy
of ESD S2020 so I can't refer to it for help in this case. Thanks!
