ESD flooring and footwear system is an effective way to ground people that need
to be on the move in a factory. The
footwear, when worn properly, is designed to drain the voltage from a person to
the floor and then to ground. Periodic
testing of both the floor and the footwear is required to verify proper
Until recently, a System Resistance Test (ANSI/ESD STM97.1) was all that was needed to qualify an ESD control flooring and footwear system. If the resistance was less than 35 megohms, it was assumed that the person’s voltage would not exceed 100 volts (the upper limit for ANSI/ESD S20.20). However, this testing is done with the person stationary and having both feet flat on the ground. What happens when the person starts moving and the entire foot is not making contact with the floor?
The most recent version of ANSI/ESD S20.20 now requires a Walking Voltage Test (ANSI/ESD STM97.2) be performed when qualifying flooring and footwear systems. The test consists of measuring body voltage generate during a six step pattern used to simulate moving throughout a facility. This test will determine the actual voltage on the person while moving. Research has shown that when tested separately, ESD floors and footwear systems may pass the resistance test, but when used together, can greatly exceed the 100 volt threshold.
the maximum voltage generated by people moving on the factory floor is very
valuable information. By knowing the
maximum voltage generated you will know that your flooring and footwear
investment is performing as designed.
You may also be pleasantly surprised to find out that the system is
working quite well and you are able to handle devices with much lower Human
Body Model (HBM) damage thresholds.
Equipment is available to accurately measure and record the
walking voltage. One such instrument is
the WT5000. The WT-5000 walking test
kit measures and records the walking voltage while providing a graphical
readout. The instrument connects to a
PC using any Windows version for easy data collection. The WT-5000 identifies the peak voltages per
the requirements in the standards.
The two-in-one EFM51WT meter
holds the PEAK value of the measured body voltage, as well as the LIVE static
voltage measured on the operator’s body. The kit includes the EFM51 static
field meter, walking test adapter plate, hand probe and
conductive carrying case. The EFM51 is a fully function
field meter that in addition to the Walking Test, measures and
detects electrostatic fields, surface potentials and discharge times (with
optional charge plate accessory – p/n 7100.EFM51.CPS.SET.)
You have made the investment in an ESD flooring and footwear
system so that people can be mobile and still protecting your products from ESD
events. Determining your actual walking
voltage generated is critical to knowing that your products are being protected.

Cuts and lacerations are responsible for nearly 30% of lost-time work injuries in North America, the majority of which are to the hands. Wearing the correct glove is the most critical factor in proper hand protection. It’s even more important to understand cut resistant gloves and the characteristics they hold. Cut-resistant gloves come in various fabrics offering different level of cut resistance. It’s important to consider the requirements of a particular application when choosing a glove material. Transforming Technologies specializes in anti-static gloves which improves the quality of products or solves a process issue.
What Are Cut-Resistant Gloves?
Cut Resistant Gloves can be divided
into three categories based on the materials they are made from: metal mesh
gloves, cut-and-sewn, and seamless knitted gloves.
Metal mesh gloves are a form of chainmail and are made of rings of stainless steel.
Cut-and-sewn gloves can be made using only a cut-resistant material or by using conventional materials with full or palm lining of cut-resistant materials. The materials are cut to shape and sewn into a glove.
Seamless knitted gloves are knitted in one piece and the cut protection is provided by high performance materials such as Para aramid (Twaron, Kevlar), Ultra High Molecular Weight Polyethylene (UHMWPE), special PVA yarns (SupraBlock) or steelfibre and fibreglass yarns. The gloves are usually coated with solid or foamed Latex, Nitrile or Polyurethane.
Which Cut Resistant Glove Is Right For Me?
Not all cut-resistant gloves are
created equal and that’s a good thing, depending on the severity of the hazards
that you’re facing. The best rated glove is the one that protects against the
hazards you face. A worker who uses a box cutter once a day doesn’t need the
same protection as someone who works in metal stamping eight hours a day.
Using a glove designed for
heavy-duty cut protection for a light-duty application has a snowballing
effect: If a worker has less dexterity in the glove, they won’t be able to do
their job right. If they can’t do their job right, they won’t wear the glove
and then compliance takes a hit. Then the risk of hand injury skyrockets!
How Are Cut-Resistant Gloves Rated:
There are two common standards used
for measuring the cut-resistant properties of gloves. One used primarily in
North America and the other is used in Europe and Asia.
North American Standard (ANSI/ISEA 105-2016): The protection level is given by a
number between 1 and 9, where 9 indicates the highest cut protection.All gloves are tested on a TDM1000
machine which provides uniform testing.
The glove sample is placed on a conductive strip and loaded onto the TDM-100. When the metal blade touches the metal strip, the test is terminated.
A straight blade is loaded into the machine.
Weight is added to serve as force.
The blade moves across the fabric.
The blade is replaced with a new one to ensure accuracy.
The sample is cut five times, each with three different loads.
The distance traveled to cause cut through at various forces is recorded.
The data is used to determine the load required to cut through the sample.
The glove receives a rating based on the above information between A1 and A9, with A1 being the lowest and A9 being the highest level of cut protection.
European Standard (EN 388): The protection level is given by a
number between 1 and 5, where 5 indicates the highest cut protection. Until 2016,
the Coup Test, as described below, was the only test used under the EN 388
standard. The standard update in 2016 introduced the ISO 13997 concept, which
closely relates to the North American standard test.
A test sample is taken from the palm of a glove.
A rotating circular blade moves back and forth across the test
sample until a cut-through is achieved.
The test sample is compared to a reference material (usually
The reference material and the test sample are cut alternately
until at least five results are achieved.
To help account for a loss is sharpness to the blade, the
reference material is cut before and after the test sample.
The cut resistance is a ratio of the number of cycles needed to
cut through the test sample compared with the reference material.
Can You Wash Cut-Resistant Gloves?
The short answer is yes. Laundering
and dry cleaning have no significant impact on the protective properties of
cut-resistant gloves. Most quality cut-resistant gloves will retain their
protective properties even after ten or more washes. It is important that you
follow manufacturer instructions when washing cut-resistant gloves.
Frequently Asked Questions:
Q. Do cut-resistant gloves offer
A. No. Many cut resistant gloves
are manufactured to protect hands from being slashed by sharp objects like
knives/blades. However, they may provide very little or no puncture resistance
from a pointed item, such as a needle.
Q. What is the difference between
puncture resistance and needle or needlestick resistance?
A. Needles are sharp, beveled
cutting instruments designed to pierce the skin. To stop them you need to stop
the cutting action by putting something hard in front of them, such as the
protective guard plates found in SuperFabric® brand materials. ASTM/EN388 test
probes are rounded and tear fabric instead of cutting as it penetrates. This
rounded ASTM/EN388 tip functions more to test bust strength whereas the .25G
medical needle tests true needle resistance. Various testing bodies throughout
the world have acknowledged this deficiency and are adapting standards to meet
this. Two examples are the Canadian research organization IRRST and the ASTM
F23 Standards committee, who are working together to design a standard that
uses the same test procedures as tested herein.
Q. Should cut-resistant gloves be
used to protect one from cuts from powered/mechanical equipment like powered
saws and drills?
A. Most all manufacturers of
cut-resistant gloves will not suggest the use of cut-resistant gloves for
protection against powered devices. Gloves are typically tested for use with
non-powered blades and sharps only.
The use of a glove with powered
equipment could potentially harm an individual. If the moving blade catches the
glove, it could result in a person getting pulled into moving machinery. Moving
machine parts have the potential for causing severe workplace injuries, such as
crushed fingers or hands, amputations, burns, or blindness. Safeguards are
essential for protecting workers from these needless and preventable injuries.
Any machine part, function, or process that may cause injury must be
safeguarded, especially when the operation of a machine or accidental contact
with it can injure the operator or others in the vicinity. These hazards must
be either eliminated or controlled.
Q. What makes HexArmor products
highly cut and puncture resistant?
A. HexArmor® products offer
industry leading cut protection through the innovative configuration of
SuperFabric® technology which provide resistance to lacerations and slashes
like no other material on the market. Typical cut-resistant products are made
of high performance yarns such as Kevlar®, Dyneema®, or Spectra®. While blends
of these technologies protect users from straight edged cut hazards, they do
not offer sufficient protection from variable hazards such as metal burrs,
wires, or slivers.
ESD jackets, also commonly known as ESD smocks, ESD lab coats or ESD garments, offer protection from electrostatic fields generated by clothing on the user’s body. ESD jackets are worn where ever static damage is a concern. ESD jackets differ from common work garments because they are made with a grid of conductive fibers throughout. The grid creates a “Faraday Cage” effect around the body of the operator that shields charges generated from the operators clothing from damaging ESD sensitive devices. The conductive fibers also lowers the static charge generation of the jacket(also refereed as tribocharging) to a safe level.
ESD Jackets as part of a complete Quality Control Program.
ESD jackets are the most visible sign of ESD protection and any facility that mandates ESD garments demonstrates a commitment ESD protection. ESD jackets are a recommended addition to a program that already includes typical grounding measures, such as wrist straps and heel grounders. This is because of the potential hazard of the operator’s clothing. The ESD TR20.20-2008 states: “While a person may be grounded using a wrist strap or other grounding methods, that does not mean that insulative clothing fabrics can dissipate a charge to that person’s skin and then to ground. Personnel clothing usually is electrically separate or isolated from the body.”
How To Choose an ESD Jacket?
A quick search online reveals numerous options for ESD jackets. We have summarized the main considerations when choosing ESD jackets:
ESD Garments come in many shapes and sizes. Typical distinctions are:
The jackets you choose will most likely depend on style preference but the ESD properties should be the first priority to ensure the jackets will protect against ESD as intended.
Level 1:Static Control Garment (surface resistivity of < 1 x 10^11 ohms resistance);
Level 2:Groundable Static Control Garment (surface resistivity of < 1 x 10^9 ohms resistance); or
Level 3:Groundable Static Control Garment System (surface resistivity of < 3.5 x 10^7 ohms resistance).
ESD jackets are classified by ESD properties (how conductive they are), with level 1 being the lowest and level 3 is highest. Level 1 jackets are typically the lowest cost but because the ESD properties are low they may wear out faster and need to be replaced more often. Level 3 jackets are conductive enough that the fabric can be used as part of the ground path for wrist straps which allows for safe, hands-free grounding. Level 2 is in the middle.
How to Test ESD Properties
There are several ways to test an ESD jacket but for general purposes, a sleeve-to-sleeve measurement is the most important. This test is used to confirm electrical continuity across garment panels and sleeve components. At minimum, an ESD jacket must be dissipative (surface resistivity of < 1 x 10^11 ohms resistance). This test is performed with a Surface Resistance Meter. The ESD properties should be included in the data sheet for the ESD jacket from the manufacturer. It is always recommended to regularly test your ESD jackets because wear and tear and laundering will effect the ESD properties over time.
Fabrics composition will vary by the manufacture but are typically made with a combination of carbon with polyester fabric or a cotton polyester blend. Commonly, the fabrics are described with a percentage. For example, 88% polyester and 12% carbon. Your choice of fabric will be determined by operator comfort and ESD performance. You may choose a lightweight polyester for warmer climates or a cotton polyester blend for cooler climates.
The amount of carbon in the jacket is important to note because this is the element that makes the jacket “ESD safe”. The more carbon, the better the anti-static performance. Lower cost ESD jackets are available with a carbon content of less than 5%, but they may not perform well or last as long as jackets with higher carbon content.
Collar Options Collar options typically include Lapel, V-Neck or Military style. The type of collar you choose will be based on user comfort and sensitivity of the application. The various collars allow more or less clothing to be exposed to your environment. V-Neck collars are the most open and may be cooler to wear. Military Collars covers the most clothing, but may more uncomfortable to wear. Lapel collars are in between the two and are the most commonly used collar.
Sleeve Terminations ESD jackets have either a Snap Cuffor an ESD Knit Cuff. The snap cuff includes three snap that adjusts for a proper fit and are typically cheaper. The three snap cuff is ideal when you already have wrist-straps, or in cases when wearers find the cuffs a little too snug. A wrist strap can be snapped to the garment sleeve and cord is attached at the hip pocket to ground both the person and the jacket.
An ESD Knit Cuff is very similar to the cuff on
the end of a sweatshirt and allows for hands free grounding. ESD Knit cuffs
form a contact path around both of the wearer’s wrists. The garment and wearer can
then both be grounded by attaching a ground cord to the 4mm stainless steel
snaps on the hip pocket.
Short sleeve jackets are also available from
Length ESD jackets come in three lengths: waist length, 3/4ths and full length. The length you choose depends on the sensitivity of the application and the comfort of the wearer. Waist length jackets leaves the most clothing exposed but may be cooler. Full length jackets cover the most clothing by going down to about the knees and are sometimes referred to as lab coats. 3/4ths length jackets come down to mid-thigh and are between the waist length and full length.
Colors ESD Jackets come in many colors, with blue the most common. The color has nothing to do with performance and is only preference by the company using them. Many companies will color code their employees with their ESD jackets. For example, employees may wear blue, management wears black and visitors wear white. High-Visibility jackets are available for safety reasons. Color options vary by manufacturer, and by fabric. Jackets may also be died to match company colors but will have a high minimum order quantity.
of ESD jackets
choose to embroidery their company logo or employee name onto their ESD
jackets. Sublimations, screen printing
and patches are also ways to add logos or names.
ESD Jackets are an important part of an ESD program. There are many styles to choose from, but ESD properties should be the most important factor in choosing an ESD jacket. After you ensure your jacket will protect your application, you have your choice of fabrics, collars, sleeves, and colors.

The conveyor belt is an indispensable part of the automatic transportation equipment. But the conveyor belt can be a major generator static electricity that can cause numerous problems, from static shocks to employees to catastrophic damage to components. The cause of static is friction, and on belt conveyors, the belt surface is continually rubbing the pulley surface, generating static electricity. As the conveyor continues to operate, the static charge will continue to accumulate and increase unless it is bled off (or discharged) in some manner. Conveyor and assembly trays can also create a static charge and shock employees.
Anti-static conveyor equipment exists, so when choosing the conveyor belt, pay special attention to whether the belt has anti-static characteristics. A surface resistance meter can be used to measure the anti-static properties of a conveyor belt. But if your equipment is not anti-static, then you must eliminate static in other ways. The first step in eliminating static is to measure it. If you can feel the static charge or receive shocks, then the charge is already way to high and needs to be addressed. Human feel static at 2000 volts, but components can be damaged with as little as 100 volts. A static field meter can be used to measure the static charge on your conveyor.
Drag chains can be a do-it-yourself solution to drain a charge, but they are not always practical or effective enough. Anti-static ionizers are the most effective method of eliminating static on conveyors. Ionizers blow specialized air that eliminates static charges. They are designed to be mounted overhead, or in targeted areas and can be effective without interfering with the movement of the conveyor or components. Ion bars are excellent for conveyors because they can cover wide areas with a relatively small footprint. A three fan overhead ionizer is also an effective ionizer for conveyors. If the target area for ionization is small, ionizing nozzles can be very effective. They provide a targeted stream of ionized air that can even be activated automatically with a photoelectric eye.
This will vary by application. Mount
ionizers at friction points in your process and the locations of the biggest static
issue. Mount the ionizer as close to the problem area as possible, but not too
close that the ionizer does not have enough time to do its job. If your employees are getting shocked, you
will want to install the ionizer just prior to the employee exposure.
Conveyors generate static due to friction, which can cause numerous problems. Anti-static ionizers are a very effective tool to remove the static charge.

Complies with ANSI/ESD S20.20 ( per ANSI/ESD S11.11 & ANSI/ESD DS11.12 )
There are THREE types of Static Control Garments that are compliant to the ANSI/ESD S20.20-2014 Standards.
1) Static Control Garment – Level 1
These smocks are primarily designed to shield the technician’s clothing from the ESD Sensitive product. They DO NOT come with a ground snap and DO NOT require a ground cord. When these static control garments come into contact with the users skin (the user’s skin is about as electrically conductive as the garment) the static charge is equalized and goes to ground via the technician’s primary ground source (normally an ESD wrist strap and or ESD heel grounders).
2) Groundable Static Control Garment – Level 2
These smocks are primarily designed to shield the technician’s clothing from the ESD Sensitive product but they also provide redundant protection in the unusual event the smock does not make contact with the users skin. The ESD smock has a snap on the hip that can connect a ground cord to create a path to electrical ground. A Groundable Static Control Garment is NOT recommended as the technician’s primary ground source (an ESD wrist strap and or ESD heel straps are still required).
3) Groundable Static Control Garment System – Level 3
These smocks are designed to act as a primary ground source for the technician (they can act as a replacement for a wrist strap). In addition to grounding the technician, they will also help to shield the technician’s clothing from the ESD sensitive product. They are reliant on good skin to smock contact. Hence, they may come with ESD cuffs or snap style cuffs that fit snugly around the users wrist.
Question: We are currently experiencing difficulties with static electricity in our paint booth. All of our products cannot be cleaned well enough before topcoating and we are looking into several solutions, but wondering which actually works. I also can’t get the color to go on evenly. The sprayed paint seems to dance before landing on the sheet in funny patterns.
In the painting industry, electrostatic discharge is a constant challenge in a world where perfection is the only option–and dust and static are a constant. Static attracts dust and unwanted particles, making it very difficult to keep surfaces clean, causing blemishes in paint finishes and other work surfaces. It’s absolutely essential to eliminate static from the environment–at every stage of painting–in order to avoid costly reworking.
Specialty ionizers for the auto body industry are used to eliminate surface contamination. These ionizers allow you to keep the surface clean so you can avoid unnecessary reworking and buffing, saving both time and money. The guns work twofold: as a forceful blow off gun that easily removes particulate from surfaces and as a neutralizer to remove the charges responsible for the attraction of contaminants to product surfaces in the first place.
Anti-static wipers have been developed to clean off surfaces and can be used to clean surfaces as well. Static is caused by friction, so wiping down surfaces to remove dirt can actually make the static problem worse. The anti-static wipers are made with a specially designed fabric that will not tribocharge and will not lead to more static buildup.
ESD inspection/assembly gloves are designed to be worn when handling items that can be affected by static. They are made with dissipative nylon fibers that reduce charge generation. The gloves will decrease contamination to parts due to oils, dust and fingerprints. Cut resistant ESD inspection gloves are also available if you must handle items with sharp edges such as glass and metal.
