APPENDIX A
Field Service – ESD Prevention
Field service technicians are required to take appropriate steps to make sure they are
properly grounded before handling any circuit boards. If a field service technician is at a
site and is not equipped with a portable ESD field service kit, the technician must keep
in mind that touching a metal chassis whether grounded or not will only temporarily
bring the technician to the same potential as the chassis. This is a common
misconception by a lot of field people, that touching ground will make you safe…it will
only while your are touching ground…once you disengage that connection, you put all
sensitive ESD devices at risk.
