Equipment
Any equipment commonly found in an ESD work area, such as solder guns, heat guns, blowers, etc.,
should be grounded.
Materials
Plastic work holders, foam, plastic tote boxes, pens, packaging containers and other items commonly
found at workstations can generate static electricity.
Grounding Requirements for Personnel
The information in this section is provided to assist you in selecting a grounding method. This
information is taken from ANSI/ESD S20.20-2007 (Revision of ANSI/ESD S20.20-1999).
