Hi Edward:
If it is from electronic equipment, it may not be
ESD but an AC or DC potential. That equipment ground may be floating and if
operators are grounded may be subjected to a shock from that potential.
In general anything that generates above 0.200 KV ESD
should be removed or if it can not be removed should be kept at least 6
inches away from product. Move product in shielded totes or bags, operators
should be grounded while handling product.
Regards,
Ramon

Hi,
Recently we made some measurements concerning Electrostatic charge on
different pieces of equipment in our clean room.
I got the results from 0.05 kV/inc to 5 kV/inc , but I do not know what
is
considered tolerable and what should be treated asap.
Pls advice directions
Edward
