The primary method of grounding for these workers is esd footwear heel or toe grounders and conductive flooring.
Point to ground mehotde esd flooring checking.
For stationary personnel such as a workstation operator assigned exclusively to a bench the primary line of defense against static discharge is the wrist strap and a.
For using heel grounders and wrist straps.
Grounding to a circuit ground.
Although grounding your esd floor is imperative most installations now dictate a relatively basic grounding method due to recent advancements inherent in the new higher conductivity adhesives.
This basic method is now generally adequate in achieving an installed electrical rtg resistance to ground close to the center of the flooring systems.
In this sketch a steel column 1 is used as an attachment point 2 for the aluminum ground foil 3 for subsequent application of esd flooring adhesive or coatings 4.
The resistance tests verified that the floor measured below 1 0 x 10 7 easily complying with the resistive properties of a static control floor based on ansi esd s20 20.
The most effective way of grounding is achieved by using.
The strip can be attached using the screw and then covered with the outlet plate.

Normally one grounding point is required for every 1000 ft2 111 m2 of flooring.
Snaps on the corner of the mat allow you to bypass the floor sending static directly from the mat to an electrical outlet using a grounding cable.
Grounding conductive and static dissipative tile and sheet flooring to an ac electrical outlet is the easiest and most common grounding method.
Esd tr53 s wrist strap and footwear sections also specify testing that is used for the compliance verification plan requirements of ansi esd s20 20.
The paint will absorb the static charge but it needs somewhere to escape via a grounding point.
To test you would typically use a combo tester at the entrance to esd safe work areas.
The purpose of painting your floor with esd paint is to remove static.
Simply remove rust from steel column.
Only use electrical receptacles outlets that have been previously tested using an approved circuit tester complying with csa and or ul standards.
How to check esd grounding of wrist straps and foot grounders.
Once anti static mats are covering the table and floor you are on your way to being in compliance with ansi esd s6 1 esd grounding methods requirements for workstations.
The desco digital surface resistance meter kit measures resistance point to point rtt or surface to ground rtg of worksurfaces flooring systems garments and other materials in accordance with esd association documents.
Grounding strap will be attached to the designated esd floor ground point.
