Program and documentation

A written ESD control plan exists and names the standard it followsCRITICALAn ESD coordinator is named and known to staffThe sensitivity level of the most sensitive products handled is documentedCRITICALProtected areas are marked on a floor plan and with signs at entrancesAudit and test records are retained for the period set in the planCorrective actions from the last audit are closed or tracked

Grounding and workstations

Every ESD worksurface has a verified connection to the common ground pointCRITICALCommon point ground is connected to the equipment ground per the planWorksurface resistance is tested at the documented interval and recordedNon-essential insulators such as plastic cups and paper are removed from workstationsCRITICALNecessary insulators are controlled by ionization or a documented methodIonizers are verified for balance and discharge time at the planned intervalSoldering irons and tools are grounded

Personnel grounding

Wrist straps are worn at stations where operators are seatedCRITICALWrist straps are tested at the start of each shift or continuously monitoredFootwear or heel grounders are tested before entering the EPAESD smocks are worn and cleaned per the planOperators are not wearing ungrounded jewelry or items that contact productVisitors are escorted and grounded or kept outside the EPA

Flooring, equipment and environment

Dissipative flooring or mats resistance is measured and recordedChairs and carts that enter the EPA are ESD rated and groundedHumidity is monitored and kept within the plan's rangePick-and-place and test equipment are grounded to the common pointNo uncontrolled personal electronics are on the work surface

Handling, packaging and training

Sensitive parts leave bags only inside the EPACRITICALMoisture barrier and shielding bags are intact and not reused in damaged conditionTotes, trays and reels carry static control markingsParts are handled by the body or edges, not by leads, where possibleOperators have recorded ESD training and refresher datesCRITICALIncoming parts are checked for intact ESD packaging at receivingAny suspected ESD damage has a defined reporting and containment path

Count every item as pass or fail during your walk. Any failed critical item should be corrected before more sensitive product is handled in that area, and the result should be recorded in your internal audit records.

Audit record consolidation

Optional: we review where ESD audits, training and packaging holds are recorded and suggest a single structure.

Optional. The tool and every export work without this. No spam.

How to use the checklist

Print or export the checklist and walk the protected area with the plan in hand. Mark each item as pass or fail, and note the station or area. Failed critical items, such as an operator without a verified wrist strap or an unidentified sensitivity level, should stop work on sensitive product until fixed. Keep the signed checklist with your internal audit records.

Audit unannounced and across all shifts
Test, do not just look: use the approved tester
Record the date, auditor and area on the output

What the standard structure covers

S20.20 style programs rest on a plan, grounding of conductors including people, control or removal of insulators, protective packaging and handling, and training. Compliance is demonstrated through documented tests with defined limits. The standard describes the structure, and your own plan sets the intervals and limits, so this checklist asks whether you follow your plan rather than quoting numeric limits.

Buyer and receiving view

ESD protection starts before your floor. Buyers should specify static control packaging for sensitive parts in purchase orders and check that suppliers and brokers ship in intact, labeled packaging. At receiving, a torn shielding bag or an open moisture barrier bag is a reason to hold the lot. Record these holds in your ERP so the supplier's performance reflects them.

Common mistakes

Typical failures are wrist straps tested once per week instead of at shift start, personal items such as cups on benches, worksurface grounds that have come loose, and carts rolling in from outside the area. Audits that check paperwork only will miss these. Walk the floor, use the tester, and check the training records for new hires and temporary staff.

Frequently Asked Questions

Does this checklist certify my facility?

No. It is a self-audit aid. Certification or third-party verification is done by an accredited body against the full standard and your documented plan.

How often should wrist straps be tested?

Follow your own ESD control plan, which is commonly at the start of each shift for daily wear or continuously with a monitor. The right interval depends on product sensitivity and risk.

What counts as a critical item?

A critical item is a control that, if absent, can damage sensitive product immediately, such as ungrounded operators or unknown part sensitivity. Failures here should stop work on that product until corrected.

Do buyers need to care about ESD controls?

Yes. Buyers set packaging requirements and choose suppliers whose handling matches the parts. Poor packaging at purchase is difficult to fix once parts arrive at your dock.

If audit results, training records and supplier packaging holds sit in separate files, we can build a private agent over your ERP and quality records to show open ESD actions in one place.
