6 Things NOT to Do in an ESD-Controlled Work Area

What should you NOT do in an ESD-controlled work area? Do not assume a mat works without proper grounding, skip required personnel-grounding checks, bring uncontrolled charge-generating materials near exposed sensitive devices, treat ionization as a replacement for grounding, use unapproved cleaners, or assume installed controls remain effective without verification.

A bench can look ESD-ready and still have a broken ground cord, an ineffective personnel-grounding arrangement, or ordinary packaging where sensitive components are handled. The equipment on the bench matters, but so do the daily habits around it.

This guide covers six common mistakes in electronics assembly, repair, inspection, and prototyping. Use it to support your documented ESD-control program, not as a substitute for your facility's risk assessment, electrical-safety procedures, manufacturer instructions, or applicable standards.

1. Do NOT Assume an ESD Mat Works Without Proper Grounding

A dissipative mat is a work-surface material, not a complete ESD-control system. A suitable grounding arrangement provides a controlled path for charge dissipation. A disconnected cord, damaged connection, or incorrectly selected grounding point can undermine the intended setup.

What to do instead: Use the work-surface manufacturer's instructions and your approved ESD grounding plan. Fit compatible hardware, connect to the designated grounding arrangement, and verify the installed surface using the specified method. Do not improvise a connection to a nearby pipe or unidentified metal object.

• Check cords, snap connections, and connection points for visible damage or disconnection.
• Confirm the selected mat and grounding hardware are compatible.
• Verify performance against your program's acceptance limits, not appearance alone.

Purchasing check: Determine whether grounding hardware is supplied. A roll cut into bench sections should not be assumed to arrive with a grounding connection on every section.

Product example: The ACL Staticide 2440 Dualmat roll provides 24-inch × 40-foot material for custom bench sections. Plan compatible grounding hardware and verify each finished work surface; the roll alone does not complete the setup.

2. Do NOT Skip Required Wrist-Strap or Footwear Checks

Wearing a strap is not the same as confirming that the personnel-grounding system works. Poor contact, damaged cords, unsuitable footwear, or an ineffective footwear-and-floor combination can leave a gap in the controls.

What to do instead: Follow your facility's approved personnel-grounding method and check schedule. Use the required tester or compatible monitoring system, and act on a failed result before handling exposed ESD-sensitive devices. A successful check from an earlier shift does not resolve a later broken connection.

• Wear and fit grounding devices according to their instructions.
• Use footwear grounding only as part of a qualified footwear-and-floor system.
• Document required checks and follow the response procedure for failures or monitor alarms.

Safety check: Personnel grounding must also be appropriate for the electrical hazards of the task. Do not apply this advice to energized high-voltage work without approved electrical-safety controls.

Product example: The Desco 19240 Portable Wrist Strap Tester supports discrete wrist-strap checks at the workstation. It is not a continuous monitor, and this listing does not establish footwear-testing capability. Confirm its test limits and connections against your approved procedure.

3. Do NOT Bring Ordinary Packaging Into Sensitive Handling Areas Without Evaluation

An ordinary plastic bag, foam insert, tape dispenser, or document sleeve can introduce charge-generating material near exposed sensitive parts. Keeping the workstation mat grounded does not automatically neutralize every object placed above it.

What to do instead: Remove unnecessary materials from the protected area and use packaging approved for the device, movement, and storage conditions. Essential process insulators require evaluation and controls under your ESD program.

• Check incoming packaging before exposing sensitive assemblies.
• Use the specified packaging for transfers inside and outside the protected area.
• Do not select a bag by color alone. Verify its documented properties and intended use.

Purchasing check: Low-charging, dissipative, and discharge-shielding properties are different. A packaging choice suitable for one handling situation may not provide the protection required for another.

4. Do NOT Treat an Ionizer as a Substitute for Grounding

Ionization helps address charge on materials that cannot be effectively grounded, such as certain necessary insulators. It does not excuse an ungrounded person, disconnected mat, or poorly controlled conductive item.

What to do instead: Establish the required grounding controls first, then use ionization where your process assessment identifies a need. Follow the manufacturer's placement, operating, cleaning, and maintenance instructions.

• Evaluate the actual point of use, including distance, airflow, and obstructions.
• Verify ionizer offset voltage and discharge performance using your approved procedure.
• Keep emitters and other serviceable parts maintained as directed.

Inspection check: A fan running or an indicator light glowing does not establish effective charge neutralization at the workpiece.

Product example: Consider the Desco 50663 Zero Volt Benchtop Ionizer, 120VAC where your process requires supplemental ionization. Confirm voltage, placement, airflow and measured performance at the workpiece. It does not replace required personnel or work-surface grounding.

5. Do NOT Clean ESD Surfaces With Whatever Cleaner Is Nearby

A cleaner that looks harmless can leave residue, affect a surface's electrical characteristics, or damage the material. The wrong cleaner or unapproved coating can interfere with the properties you selected the work surface to provide.

What to do instead: Use cleaning products and methods approved for the exact mat or surface material. Follow dilution, application, drying, and safety instructions. If the bench is also in a controlled environment, confirm that the cleaner meets those contamination-control requirements.

• Identify the surface material before choosing a cleaner.
• Avoid unapproved waxes, polishes, and residue-forming products.
• Investigate changed resistance readings or visible damage rather than masking the problem with more cleaner.

Purchasing check: “ESD-safe” on a cleaner label is not a universal compatibility guarantee. Match the product to the surface manufacturer's recommendations and your facility's approval process.

Product example: Review ACL Staticide 6001/6002 ESD Mat and Table Top Cleaner for compatible surfaces. Select the required package variant, follow both ACL's and your mat manufacturer's instructions, and verify electrical performance under your ESD program. Do not assume it is approved for every mat.

6. Do NOT Assume Installed Equipment Stays Effective Forever

A successful initial setup is a starting point. Cords wear, connections loosen, surfaces become contaminated, and process changes introduce new materials. A bench that passed once can drift outside its intended controls.

What to do instead: Maintain a documented verification plan covering the applicable work surfaces, personnel-grounding systems, grounding connections, packaging controls, and ionizers. Define methods, acceptance criteria, frequencies, records, and corrective actions for your process.

• Separate routine visual checks from the electrical measurements your program requires.
• Review controls after workstation moves, repairs, material changes, or unexplained failures.
• Respond to monitor alarms and failed tests using a defined containment and correction procedure.

Management check: Do not invent one universal inspection interval for every operation. Use the applicable requirements, equipment guidance, process risk, and your documented program to establish the schedule.

A Practical Pre-Work Review

Before exposing sensitive devices, confirm that the approved workstation setup is in place, required personnel checks are complete, packaging is appropriate, unnecessary materials are removed, and failed checks or alarms have been resolved according to procedure.

The goal is not simply to own ESD equipment. It is to maintain a verified system that fits the devices and tasks at your facility.

Frequently Asked Questions

Is an ESD mat enough to protect a workstation?

No. Work surfaces, grounding, personnel controls, packaging, and process-specific measures need to work together. The required combination comes from your documented ESD program.

Can an ionizer replace a wrist strap?

Do not treat ionization as a replacement for required personnel grounding. It serves a different purpose, particularly for necessary materials that cannot be effectively grounded.

Are all pink bags suitable for transporting sensitive components?

No. Color does not establish discharge shielding or suitability for a particular transfer. Select packaging by its documented properties and the conditions of use.

How often should ESD equipment be checked?

Use the frequencies and methods established in your verification plan, applicable requirements, and manufacturer instructions. This guide does not prescribe a universal daily or monthly interval.

Can I use an ordinary disinfectant on an ESD mat?

Only if it is approved for that exact material and your facility's process. Review surface compatibility, residue, and any controlled-environment requirements before use.

Does buying compliant equipment make the whole area compliant?

No. Product properties do not establish the performance of the complete installed system. Correct use, training, verification, records, and corrective actions remain part of the program.
