Managing Static and ESD in Call Centers

Thanks to movies and TV, no matter how old you are, you’ve probably seen the old switchboards – whether it’s on Agent Carter or reruns of the Andy Griffith Show – and computers that barely fit inside a room – like in The Imitation Game or the TV show Manhattan.

Nowadays, of course, we carry the switchboard and the computer in a handy-dandy pocket device.

Likewise with emergency services. When we call 9-11, we expect a prompt response, and the person on the other end of the line assures us that police, fire, or ambulance are already in route as they continue to gather our information.

Computers help planes land, monitor traffic on the freeways, and even park your car for you.

But for all the advances in technology, there have been setbacks as well.

In the old days, phone and computer systems were built “solid-state.” Everything was confined within one unit and was protected from outside forces. Internally, they were defended from ElectroStatic Discharge (ESD) by microcircuit gate protectors.

Unfortunately, these gate protectors, while highly effective, tended to slow down the machines they were protecting – kind of like how some companies’ virus protection forces their machines to crawl.

As technology progressed, emergency services, military bases, and flight control centers started abandoning these more stringent preventative measures, in favor of speed.

The end result being, while these computers and call centers are protected in buildings made to withstand hurricanes, earthquakes and power outages, they can be disabled or even rendered completely useless by the tiniest static shock.

Which is why the proper ESD protection and protocols are so important in these mission critical locations.

Another factor to consider is that these facilities are typically open 24-hours a day and have hundreds of people pass through them on a regular basis. Some of them are trained and properly equipped with ESD shoes, heel grounders and even personal wrist straps, but certainly not all of them.

And when there’s a crisis and everyone needs to scramble to get the problem solved, the first thing to go is proper ESD procedures.

The answer is to make these facilities as static proof (or charge proof) as possible.

Like your skin (the largest organ in the human body), flooring is the largest and most vulnerable area for ESD buildup and discharge, if it’s not handled properly.

There are many options for ESD flooring, as we’ve discussed in prior posts, but in this instance, there are really only one option: carbon-fiber laced carpet.

The first thing you should know is that not all ESD carpet is created equal. Some companies promote and sell an ESD carpeting that is treated with a chemical to reduce static that disintegrates over time and must be reapplied.

Avoid these – you don’t want your static protection to be subject to a random timetable. Again, these facilities are always open. You’ll want to invest in a carpet whose static-prevention comes from the permanent physical composition of the materials.

For the same reason, you’ll want to invest in an ESD carpeting that is certified by ANSI/ESDA standards and reduces static regardless of the humidity levels or footwear worn by the personnel.

As an added bonus look for ESD carpet that is low maintenance, crush resistant, able to handle heavy foot traffic and comes with a lifetime warranty.

Can New Flooring Be Installed Over Old?

Whether your company has just invested in a new to them facility or is upgrading their current locations due to time or elevated ANSI/ESD standards, one of the largest expenses they will face is replacing the existing flooring.

Based on the existing installation, this can be a very time consuming task – days to strip off the old flooring, etch or acid burn off any leftover adhesive residue. Plus the very real possibility of damaging the concrete itself or a pre-existing moisture barrier.

Which leads to a popular question from facility and production managers – can new ESD flooring be installed over existing flooring?

And depending on who you talk to, the answer is: Yes. No. And, of course, Maybe.

Yes.

If an existing floor is well-bonded, ANSI/ESD 20.20 compliant and in reasonably good condition, theoretically, the answer is yes.

Certain flooring options pose a lower risk and are considerably easier to install over an older floor. Vinyl, for example, generally can be installed over top existing vinyl. Generally.

Problems arise when the old floor has become hard and stiff. It may be harder to install over it, and if the initial bond doesn’t take, vinyl is unforgiving and may delaminate – requiring a complete stripping and reinstallation that is likely to cost more than the initial money saved, not to mention the time lost during the removal and reinstallation.

An additional choice to consider is installing carpet tiles over old vinyl. Carpet has become a popular choice to install over existing floors because the irregularities of the surface below the carpeting are virtually hidden behind its barely reflective surface.

Another option is Zero Stat Crete – a state of the art water-based epoxy coating – which can, after proper testing, be applied over an area that has had the previous vinyl or carpeting tile removed – often without needing to strip off any leftover adhesive.

No.

Some experts caution that you should NEVER install a new floor covering over an old one. Along with the warnings above, the old flooring might hide structural defects, might not be properly bonded or might result in a plasticizer contamination of the new flooring, which could radically affect the quality and effectiveness of its ESD prevention.

Also, by not removing the old flooring, moisture concerns that need to be addressed may not be discovered.

Additionally, depending on the age of the old flooring, it might have been made with asbestos, a manufacturing material that causes severe respiratory problems and may lead to death.

Maybe.

Experts say that almost any floor can be installed over an old floor as long as the old floor is in good condition and well-bonded to the sub floor. BUT…

There are just too many variables to accurately consider or discuss every flooring replacement or recovering option in a single posting.

Even if your scenario is similar one of the ones we’ve elucidated above, there may be additional factors in your specific facility that are not taken into account in our hypothetical illustrations.

Which is why we always recommend speaking to a qualified flooring professional before making any final decisions. There is not usually a financial cost associated with their consultation and/or site visit, but the preventative savings far outweigh any nominal up front cost.

Monitors & Meters: Which One Do You Need?

Monitors and meters may seem like merely a question of semantics. And in most of the world it is, monitors are analogous with meters and vice versa.

But when you’re dealing with electrostatic discharge (ESD) prevention, both have specific purposes and uses that set them apart from one another. And it’s important you know which is which before you start or continue your work with items that can be harmed by ESD.

Monitor: What’s Happening in the Room?

In plain language, in an ESD Prevention situation, the Monitor (noun) keeps known sources of ESD in systematic reviews. It monitors (verb), the ‘progress’ or quality of ESD buildup over a period of time.

So we have monitors for people, that connect to their personal wrist straps, or connect between them and the ESD matting that they are using – in effect, monitoring both.

The key to a good ESD monitor is make sure they provide constant monitoring of the potential ESD in the room. If the monitor fails, a single spark of static electricity can cost hundreds of dollars in damage before it’s quelled.

Meter: Where Is It?

Meters, in an ESD prevention situation, operate more as the means to locate the sources of ESD build up.

Much like the meters used for testing in construction situations, meters will show the relative ESD levels, allowing the user to pinpoint the exact spot where ESD is being generated or not dispersed properly.

This can be on ESD mats, clothing, people and flooring.

Specialty meters can detect and pinpoint ESD specifically in a cleanroom or ionized area.

There are meters that look at a wide variety of potential ESD buildups and smaller units that check select areas only. And meters that check the humidity, temperature, electrical resistance, and any or all of these at once.

There is a secondary subset of meters that you should also be aware of – Testers.

Testers check the grounding of electrical receptacles to ensure they are actually grounded. Imagine the problems and expense of not realizing your electrical plugs were not grounded and subsequently having to discard or repair any sensitive electronics that had been worked on or assembled during the time the ground was inactive.

There are also testers for personal wrist straps and grounding cords.

Are You ESD Aware?

So, the answer to our question above is YES.

It’s not an either/or situation. It’s both. Each tool has its purpose within your ESD control situation, and both are effective in their job – which is generating awareness of ESD.

Is Bare Concrete Really the Best “Anti-Static” Flooring?

There used to be an old wives’ tale that standing on bare concrete for too long caused varicose and spider veins. In the 60’s, that idea was largely supplanted by the hippie movement that believed standing shoeless on bare concrete allowed the body to become more grounded.

Unfortunately, it seems that the once-held hippie belief has permeated into the world of electrostatic discharge (ESD) prevention. But nothing could be further from the truth. Because while bare, unsealed concrete floors that are allowed to ‘breathe’ have anti-static tendencies, they are definitely NOT grounded.

Nothing to Cling To

While the lower expense of a bare concrete floor makes it appear like a desirable remedy, there are several reasons it is not classified as a true ESD flooring solution.

First there’s that word – tendencies. Bare concrete floors tend to be anti-static, but they are not reliably so. That’s because anti-static characteristics are not inherent in concrete like they are in a carbon-filled material or a poured ESD epoxy.

To further complicate the issue, the measure of how anti-static concrete is, is dependent on many variables – the most significant of which is its permeability to moisture. If you’ve explored our website at all, that should immediately raise a red flag. In an earlier post, we talked about why moisture is the #1 enemy to your ESD flooring.

A Shift in Standards

If that doesn’t scare you away, we discussed in this post about how anti-static is not an adequate measure for ESD flooring. To summarize, the term “anti-static” refers to a material that resists generating a charge. And bare, sealed concrete does do that – most of the time. But over the past 30 years or so, ANSI and the ESD Association made the effort to remove the term from their professional industry standards because it was so overused and misunderstood.

Those standards are discussed in this post.

And for good measure, we discuss in another post the dangers of cutting corners to save money when building your ESD Protection Area (EPA). Some up front expenses are definitely worth the long-term benefits.

Fully Charged

So, let’s assume that the concrete floor you’ve just installed is as anti-static as it can get. You can walk across it to any other part of the room and there will be no static buildup, aka triboelectric effect.

But what happens when the CEO comes down to inspect the area, and as he’s walked from his office to the EPA area, he’s built up a static charge. It’s on his body, on his clothes; we know that even the slightest movement in a conductive area builds a charge that can damage sensitive electronics.

When he hits that concrete floor, the charge doesn’t just disappear. It stays with him. Because while concrete has the tendency to avoid building up a static charge, it does nothing to dissipate an existing charge. And this is the biggest problem with the use of concrete as an ESD floor. It cannot act as a ground.

The CEO touches a circuit board, it gets the electrostatic discharge, ruining it – and he blames you. And then you have to install a true ESD floor anyways. Why not just do it right the first time?

Conductive, Dissipative, or Anti-Static Flooring?

You’re hard at work at your latest assignment. Your boss wants you to put together a complete plan for creating a large-scale electrostatic protection area (EPA) for a client who will be assembling various sensitive electronics and they want to avoid any risk of losing their investment due to electrostatic discharge (ESD).

You’ve selected the grounding cables, the workstations, the custom cut matting, containers and furniture, all designed to minimize or eliminate the slightest chance of ESD damage. But a curious thing happens when you research the proper flooring.

A simple Internet search for ESD flooring yields numerous options, more than you expect and you start to notice they all fall under 3 categories. In an instant, you’re faced with a decision, just like the game show, “Let’s Make a Deal.”

Suddenly, Monty Hall (or Wayne Brady, the current host!) is staring at you, asking do you want to choose door number one, number two, or number three: conductive, dissipative, or anti-static? The clock is ticking… How do you decide?

Door #1

For starters, let’s eliminate one of your options. Much like the ‘ZONKS’ of the game show, ‘anti-static’ is a worthless term in your ESD vocabulary. By strict definition, anti-static refers to a material that resists generating a charge. At one time it did designate a level of resistance, but was so overused and misunderstood, the term was removed from the ANSI/ESD standards.

So likewise, eliminate the term ‘anti-static’ from your discussion.

Deciding between the other two doors requires a closer look at the specific needs of the area for which the flooring is intended.

We’ve talked in another article about Ohms (Ω) and how they are the unit of measurement for resistance to electrical current.

Door #2

Because of the size and scope of most areas where it is necessary, the most common form of ESD flooring is referred to as ‘Static Conductive.’ Conductive flooring is at the low end of the electrical resistance scale.

Conductive carpeting may even be laced with carbon lines or metallic yarn fibers to encourage the flow of electricity. Because of the low electrical resistance, electrons flow easily across and through the surface, and can be grounded safely and quickly. This carpeting or vinyl tile is laid down with a conductive adhesive and grounded through the use of conductive tape or copper strips that run to a common ground.

This type of flooring is also generally a little more cost-effective than a dissipative solution.

Door #3

On the higher end of the resistance scale falls ‘Static Dissipative’ flooring. The higher resistance of these materials keeps the electrical charge more under control as it slowly flows over the surface and into a ground. Dissipative flooring is much more common in shared office environments where everyday shoes are more common, as opposed to a location where every element, from furniture to footwear, is controlled.

In our example above, the client will be assembling sensitive electronics like circuit boards and such in a large-scale environment. In this instance, a vinyl tile, or a poured epoxy flooring with conductive properties would most likely be the best option.

In an office setting where a company has their own IT department that fixes and assembles computers within the same facility, a dissipative, static resilient tiled floor would be a better fit.

But the fact is, these are very simplified examples of the myriad of variables that you can encounter when selecting the proper ESD controlled flooring. Your best option is to talk to an expert.

Conductive vs. Dissipative Materials

In the mid-1820’s, Georg Ohm, a self-taught mathematician and physicist, began doing experiments in the newly discovered field of electromagnetism. Hoping to advance his stalled career, he used the work of Hans Christian Ørsted as a jumping off point, discovering an inverse mathematical relationship between current and resistance.

Georg Simon Ohm

Unfortunately, in an effort to make his theories more understandable to non-mathematicians, he managed to alienate the scientific community and his groundbreaking work went unrecognized for almost 15 years.

Today, he’s remembered by the law that bears his name and its legacy, the standardized unit by which we measure electrical resistance – the Ohm (Ω).

Electrical Resistance: The Water in Pipe Analogy

To put it simply, what Ohm had discovered, but failed to adequately communicate, is that electricity acts like water in a pipe. In this analogy, resistance tells us how wide or narrow the “pipe” transmitting the electricity is.

When two items touch each other, they create an electrostatic charge – one item is positively charged, and one negatively charged. When the items are separated, it creates a triboelectric effect – a buildup of potential energy which can result in an electrostatic discharge (ESD).

In our quest to prevent ESD, which can be damaging and potentially catastrophic to sensitive electronics and circuitry, there are several approaches that vary, depending on the situation.

To illustrate those, we go back to Ohm’s electrical “pipe.”

At the narrowest end of the pipe, we have insulative materials – wood, carpeting, plexiglass. Insulative materials prevent or severely limit the flow of electrons across their surface.

While it may seem that this is the highest and best protection, the opposite is actually true. Because insulative materials are self-contained, they do not ground – meaning the potential energy continues to build up without going anywhere, until it comes into contact with another object, at which point, the new item is bombarded with the electrostatic discharge.

At the widest end of the pipe, we find the conductive materials – copper, steel, water. Conductive materials offer almost no resistance to electrostatic discharge. The electrical charge moves quickly through the materials – too quickly, which can lead to significant problems, as well as safety hazards.

In between these two extremes are the two materials most often used for ESD storage containers, matting and flooring: static conductive and static dissipative.

Towards the wider end of our metaphorical pipe, we find static conductive materials. Because of the low electrical resistance, electrons flow easily across the surface, and can be grounded safely. Typically, static conductive materials are most often used for ESD flooring.

Towards the narrower end of the pipe we find static dissipative materials. The higher resistance of these materials keeps the electrical charge more under control as it slowly flows over the surface and into a ground. Static dissipative materials are much more commonly used for ESD prevention and can be found in table top mats, ESD shoes and some flooring.

For storage containers – boxes, bins & totes – both conductive and dissipative materials can be used, depending on individual needs. Just keep in mind that dissipative materials have a higher resistance than conductive materials.

Why Moisture is the #1 Enemy to Your ESD Flooring

It’s hard to walk down a sidewalk these days without seeing a crack in the pavement. Some of these have obvious reasons, like strong tree roots pushing them up, while others seem to appear out of nowhere.

When concrete is initially poured on a flat surface, to create a floor or sidewalk, it is left for a day or more, depending on the location, to cure. Curing is the process by which the concrete is protected from evaporation until it hardens.

The wetter and cooler concrete is while it’s curing, the stronger and less permeable it is.

I know what you’re thinking… Wait. Why does this matter to ESD flooring? The short answer is more than you know.

A Concrete Problem

Because of the unique nature of the concrete curing, moisture is captured within the concrete. Again, this helps the concrete stay stronger and last longer. But it has an unfortunate side effect.

You see, concrete cracks when the moisture inside it evaporates faster than it can draw replacement moisture from the ground under it.

You may have noticed that a bare concrete floor is unusually cooler than its surroundings. There’s even the old wives tale about walking on bare concrete causing arthritis flare-ups.

But concrete doesn’t just capture moisture during curing. After hardening, it also transmits the moisture and the temperature of the ground below it.

All of this leads to the number one reason electrostatic discharge (ESD) preventative flooring fails: moisture permeation.

Flooring Failure

When too much moisture moves through the concrete, it results in a high alkalinity in the concrete. The higher pH levels react to the bonding agent, causing the adhesive in many instances to fail. And if that failure isn’t discovered, could even lead to mold between the concrete and the flooring.

A properly constructed system built recently should include a vapor barrier – a plastic shield that lessens the moisture transference of the concrete flooring. But older buildings may not include this and preventative measures should be taken.

The best and most economical solution is to install resilient flooring to the concrete base before laying down the adhesive backed ESD flooring. Resilient flooring is an organic floor surfacing material in sheet or tile form: rubber, vinyl, cork, or linoleum are all viable options.

You can also apply a resin-based moisture barrier coating before laying down your ESD flooring tiles.

A more efficient method is to simply pour a static conductive water-based epoxy floor covering. This eliminates the need for an additional layer of ESD flooring as the epoxy itself provides the protection.

What you can’t do is nothing. Moisture-related floor covering failures are responsible for over $1 billion annually in damages.

How Do You Care for Your ESD Floor?

So you’ve finally got your brand spanking new Electrostatic Discharge (ESD) preventative flooring installed. It looks great, it works great. But how do you keep it that way?

You’re smart enough to know that just like this is a specialized floor, it requires specialized care. Not just any cleaning products will work. You certainly don’t want to void the warranty, or even worse, compromise the ESD properties of the floor. That could drastically escalate costs – replacement of the damaged electronics, replacing the floor itself – having to apologize to your clients and replace the electronics they trusted you to provide.

You can’t find anything in the installation instructions. You hear the boss’ voice around the corner, you know he’s going to ask these questions. You don’t have the answers. You look down and you’re not wearing any pants!

Well, we can’t do anything about your pants, but we do have some answers to avoid that other nightmarish scenario.

For starters, take a break – for the first 5 days following a new installation, don’t wash or machine scrub the floor. This allows the adhesive to properly bond with the concrete base, as well as to prevent excess moisture – the #1 enemy of ESD flooring – to interfere with the adhesive.

The First Steps

Once the first week has passed, do an initial maintenance cleanup. Sweep or dust mop the surface to clear it of all sand, grit, debris, or dirt. Then mix a neutral pH detergent with a small bit of water in a mop bucket.

Dip the mop in the solution and fully wring it out. It is important to ONLY use a damp mop. Do not flood the floor with cleaning solution. Use as little liquid as possible to clean the surface.

If needed, scrub the floor using a rotary scrubber with scrubbing pad or automatic scrubber with scrubbing pads. Again, using as little water as possible!

Use the wrung out mop or a wet vac to wipe up any excess cleaning solution. Carefully rinse the surface with cool, clear water, but not too much, and again vacuum or damp mop up the water and let it dry.

Never use standard floor wax or standard floor finish! Doing so will destroy the floor’s ability to prevent ESD. A high gloss appearance can be achieved with a high speed buffing machine with an untreated polishing pad.

Daily Care & Cleaning – Two Options

For your day to day cleaning and upkeep, there are two standard approaches for ESD flooring. Both are viable, but for obvious reasons, we prefer the first method.

Safety First!

Always be aware that a wet floor is more slippery, and therefore more dangerous to personnel. Try to coordinate cleaning of the floor to the end of the workday when fewer people are around, put up appropriate signs, and always exercise caution to prevent workplace injuries.

The first step in either case is to sweep or dust/dry mop the surface.

Dry Maintenance Method (Option 1)

By limiting the amount of liquid your floor is exposed to, you stand they best chance of avoiding the #1 enemy of ESD flooring – moisture. The Dry Maintenance Method is a simple, single step process.

Spray clean or burnish floor using a 1200 – 1500 rpm rotary buffing machine with appropriate pads (usually white) and a spray buff solution containing water, alcohol and a pH neutral detergent.

If heavy cleaning is necessary use a more concentrated pH neutral detergent and a brown pad.

Wet Maintenance Method (Option 2)

Similar to our initial cleanup procedures following installation, the wet maintenance method uses a damp mop and a cleaning solution that includes a neutral pH detergent.

If the floor is exposed to grease or oil, a pH neutral, citrus-based degreasing detergent may be used.

Scrub with rotary scrubber with scrubbing pad or automatic scrubber with scrubbing pads. Again, do not flood the floor with solution, water or any liquid.

Wipe up the solution with a damp mop or wet vac.

Carefully rinse with clean cool water, wipe it up, then let the floor dry (generally overnight).

Two final notes:

Several times we’ve mentioned using a pH neutral detergent. While there are many options, we highly recommend the industry standard – ZeroStat products. They can be purchased through our site or any reputable supplier of ESD preventative products.

Earlier, we recommended not using a standard floor wax. While there are professional ESD waxes available from ZeroStat that maintain the ESD preventative properties of your flooring, even those waxes generally cut five to ten tears off the life of your ESD floor and should be used with caution.

What Are ESD Mats & How Do They Work?

Static Electricity and ESD Matting

Have you ever been working in your garage and accidentally made contact with a metal part of an ungrounded electrical appliance, like a box fan or a badly wired junction box? The jolt you receive wakes you up faster than a cup of coffee or one of those 5-hour energy drinks. Now imagine what that could do to sensitive electronics—devices and circuit boards with a much lower resistance than your skin.

Considering just the physical activity of moving your arms and legs can build up relatively large electrostatic discharges (ESD) that we may never notice, there’s very little activity that isn’t dangerous to electronic components – even their assembly. But there are steps you can take and tools that have been developed to protect your sensitive electronics. One simple, popular tool is an antistatic or ESD mat.

How Does an ESD Mat Work?

Antistatic or ESD Mats have a high electrical resistance, which allows the electrostatic discharge to “flow” across the surface of the mat at a slow rate – enough to get the ESD away from your electronics, while at the same time neutralizing what little charge inevitably does build up.

The simplest form of an ESD mat is simply that – a tabletop mat, about the size of a placemat, that you use on a desk, table or any flat surface. They typically connect with a personal grounding wrist strap – adding additional protection by drawing any ESD charge away from the person working on the device.

ESD mats also use a common ground to draw the electrostatic discharge away from offending areas. Without that ground, the mat could, in theory, protect the item being worked on at first, but would then transfer the ESD to the very next thing it comes into contact with – the next item, the person holding it (and then to the item), or even right back onto the item it was originally meant to protect.

For larger workspaces, or dedicated ESD workstations, you can invest in rolls of ESD matting or custom-sized mats. You can even get ESD matting with built-in static control monitors and self-adhesive backing. Just make sure, regardless of the size or quantity used, that all of the mats are grounded.

You can also increase protection as well as worker safety by investing in ESD flooring mats, which not only act as further neutralization of potential electrostatic discharge but also can provide cushioning, easing the fatigue of the person standing while working on the electronic devices. The hazard of slippery floors is also alleviated by an ESD flooring mat.

Bear in mind that not all ESD matting is tested to the same level. We recommend checking to make sure the mats you are buying are properly assessed to ensure you are getting the protection you need, and ideally, include ISO certification for your company’s protection.

Building an Electrostatic Protected Area (EPA)

Almost everyone’s familiar with the image of a white “cleanroom” or “bunny suit.” They show up in just about every depiction of people working in computer facilities in popular entertainment, and it’s a highly sought after specialty ‘armor’ in the video game Fallout 4.

What most people may not know is that the suits are designed not to protect the person inside, but the delicate circuitry they’re working on. But not everyone who works with small, sensitive electronics needs to spend money for a full-on, disposable suit.

If you work with a lot of small electronics, a more affordable solution is to put together an electrostatic protected area (or EPA). This doesn’t have to take up a lot of space and can actually be quite portable. It just needs to be done properly.

Let’s start with the basics and work our way up to the safest and most expensive options.

Simple EPA

At a bare minimum, all personnel working within an EPA should have a personal grounding wrist strap. These make sure any excess energy is grounded – forced away – from the electronic devices and circuit boards being handled.

Connected to that grounding strap is a dissipative mat. Dissipative means quite simply to disperse or disappear. A properly designed and implemented dissipative mat does for the surface what the grounding wrist strap does for the person – protects sensitive electronics from electrical discharges.

Mats can be purchased pre-cut or in rolls, depending on what your needs are.

Attached to both of these is a common point cord, also referred to as a grounding cord. These cords are fully insulated and take any electrostatic charges away from the person and the ESD mat to be grounded safely.

Often these simple options are packaged together as a field service or workstation kit that can be purchased as one unit to avoid forgetting any key elements.

Now that we’ve established the minimum requirements for an EPA, let’s look at additional options that can be easily implemented within your system to further insure the safety of the components and reduce the risk and excess cost of replacement.

From the Ground Up

For more permanent EPA installations, there are a variety of flooring options that can be integrated. Everything from conductive and dissipative vinyl tiles to anti-static carpeting that can be utilized in the work area or just in the area surrounding your EPA system. You can even add flooring with a high-end moisture barrier as well as anti-static protection.

Sole Protection

One of the most obvious ways we build up a potentially dangerous electrostatic discharge is just by walking. Static charges build up naturally. While a personal grounding wrist strap will help dissipate the charge, there are additional options for your feet.

Shoe covers with conductive strips are a quick, low cost addition to an existing EPA system and great for alleviating the risk of allowing visitors into the EPA area.

For employees whose duties mean they spend substantial time in the EPA area, you can add foot and heel grounders, toe grounders and sole grounders.

For even more protection, grounders can be upgraded to ESD shoes. These come in a variety of styles for your business setting – even weatherproof boots and hiking models.

Additional Considerations

Adding isolation protocols and ESD protective containers can also complement your EPA system and reduce the chance of any accidental charges building up or discharging into your electronic components.

Of course grounding should be a consideration with any additions to your EPA system. Whether it’s flooring or matting, grounding cords with a built in resistor add that much more protection to your area. And the more working parts you have, the more grounding capability you require.

There are simple options to increase the grounding ability of any size EPA system, as well as monitors that can be added to the system – at the personal or system-wide level.

And if you really feel the need to cover yourself top to bottom, there are more workable clothing options as well.
