“Compliance verification should be performed prior to
each use (daily, shift change, etc.). The accumulation
of insulative materials may increase the foot grounder
system resistance. If foot grounders are worn outside
the ESD protected area testing for functionality
before reentry to the ESD protected area should be
considered.” (ESD SP9.2 APPENDIX B - Foot Grounder
Usage Guidance)
“Compliance verification records shall be established
and maintained to provide evidence of conformity to the
technical requirements.” (ANSI/ESD S20.20 section 7.3)
