About Cut Resistant Gloves

April 1, 2019

GL2500 StaticCare ESD Cut Resistant Gloves

Cut Resistance Gloves

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.

Transforming Technologies supplies a Cut Level 2 ESD Gloves.

  1. 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.
  2. A straight blade is loaded into the machine.
  3. Weight is added to serve as force.
  4. The blade moves across the fabric.
  5. The blade is replaced with a new one to ensure accuracy.
  6. The sample is cut five times, each with three different loads.
  7. The distance traveled to cause cut through at various forces is recorded.
  8. The data is used to determine the load required to cut through the sample.
  9. 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.

  1. A test sample is taken from the palm of a glove.
  2. A rotating circular blade moves back and forth across the test sample until a cut-through is achieved.
  3. The test sample is compared to a reference material (usually cloth).
  4. The reference material and the test sample are cut alternately until at least five results are achieved.
  5. To help account for a loss is sharpness to the blade, the reference material is cut before and after the test sample.
  6. 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 good puncture-resistance?

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.

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.

 

How can I eliminate static electricity when spray-painting?

August 3, 2017

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.

Answer:

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.

The Wireless Wrist Strap – Do They Work?

 We Put Them to the Test!  And They FAIL!

The wireless wrist strap has been available for over 10 years.  We have seen them used in the electronics manufacturing and other assembly applications and have received several inquiries about their performance.

In this blog, we test and report on the effectiveness of the wireless wrist strap. Our results indicate wireless wrist straps fail to ground operators or keep operators sufficiently neutral. Read why the wireless wrist strap system results in a potential nightmare of problems and view the hard data that proves they don’t work.

Background: The Wireless Wrist Strap Dream

It would be nice to be able to effectively drain the charge from a person without them tethered to a work station with standard wrist straps or other ground connection.  ESD flooring and footwear is an option, however it can require a significant investment for it to be effective. Hence, the dream of the wireless wrist strap.

So what about the wireless wrist strap?  The advertising says “This compact wrist strap eliminates static without the need for a pesky grounding cord.  This allows you freedom of movement so you can leave your work area without needing to unclamp yourself and lose your anti-static protection.”  It also states that the band “…ensures that you have a much smaller static build-up and dissipates it quickly.

Wireless Wrist Straps vs. Physics

That all sounds wonderful in theory, unfortunately it does not work as advertised.   Most companies follow the ANSI/ESD S20.20 standards for their ESD Control Programs which requires human body voltage to be less than 100 volts and the wireless wrist strap does not meet the requirements of the standard.

The standard states “All personnel shall be bonded or electrically connected to the grounding/equipotential bonding system when handling ESDS items.” The standard goes on to list the requirement of a resistance between the operator and ground of less than 35 megohms.  This requirement seems quite impossible to meet with the wireless wrist strap.

Corded wrist straps

Resistance to Ground of person wearing a corded wrist strap

wireless-wrist-strap-walking-test

Resistance to Ground of person wearing wireless wrist strap

But what if you are not tied to the industry standard and just want to make sure that you are not generating excessive voltage that could harm electronic devices or assemblies?  The voltage generated and stored on the person is what is important.  So let us conduct another measurement that compares the voltage generated on a person that is a: not grounded, b: grounded through a conventional wrist strap/cord system and c: a person wearing the wireless wrist strap.

The Walking Test

For this test we will use the Warmbier WT5000 walking test instrument.   This instrument measures and records the voltage on a person while walking or simply standing.  To measure the voltage we held the test electrode on the instrument and repeated the six step walking test described in ANSI/ESD STM97.2 – Voltage Measurement in Combination with a Person.

Figure Standard shoes, tile floor, with no wrist strap

Figure 1: Standard shoes, tile floor, with no wrist strap

You see that from Figure 1 that the voltage on the person wearing standard shoes on a tile floor and no wrist strap was greater than -500 volts.   This voltage is well in excess of the damage thresholds for many devices today.    Next we will try the same floor and footwear but the operator will wear a standard wrist strap with coil cord (Figure 2).

Standard shoes, tile floor, wearing corded wrist strap

Figure 2: Standard shoes, tile floor, wearing corded wrist strap

In this case you should notice that the voltage is minimal.   The peak voltage was -1.41 volts and the valley was +0.46 volts.

Finally, we test the same floor and footwear with the wireless wrist strap (Figure 3).

Cordless wrist strap

Figure 3: Wireless wrist strap

The graph in Figure 3 shows that while wearing the wireless wrist strap, voltages of greater than

-100 volts were reached within one second of the test and peak voltages exceeding -500v were reached in less than 10 seconds.

Wireless Wrist Straps are Unacceptable

So in addition to not being electrically bonded to ground, the wireless wrist strap does not prevent charge build-up or decay charge at a rate that is acceptable for handling electronic devices.

It would be nice to be able to handle electronic devices without that bothersome coil cord getting in the way or without having to invest in a flooring and footwear system, however the reality is that a person must be physically and electrically attached to ground to drain charge from their body.

Medivators training31

 General Static Charge Audit

Find out if your facility has static charge in locations that can be harmful to your manufacturing process. The work includes benchmarking of each step of the production line, measuring electric fields and electromagnetic interference caused by electrostatic discharge.  A report is supplied with interpretation of results and assessment of the magnitude of each item found.

Additionally, this service can also include a search for ESD induced transient EMI. This can be important in facilities with lots of computer-driven robotics or automated testing. This type of EMI can disturb microprocessor operations resulting in locked up  or stopped robots, other robotic unexplained behavior or cause good parts to test bad.

Facility Review

Includes a complete static charge audit and detailed review of each step in the manufacturing process. If you prefer, the study can focus on one part of the manufacturing process, for example photolithography.

Where problems are identified a selection of choices of solutions are recommended.  In addition. The study focuses on identifying the steps required to achieve best practices concerning personnel grounding, garments, equipment grounding, hand tools, chairs, work surfaces and automated handling procedures.  A report is supplied with recommended upgrades to the facility intended to improve facility ESD safety.

Ionizer Performance Verification

Find out if the ionizers in the process are working properly and if they are correctly designed in so that they can achieve the results required,  If the ionizers are in need of maintenance or adjustment you will know it.  If ther ionizers can be made to work better, you will receive recommendations.  If the ionizers used are the wrong type or if additional ionizers are required, the report will include these facts.

Ionizer Service: Clean and Calibrate

Corona ionizers collect material from the environment much like a dust precipitator.  That material lowers the efficiency of the ionizer and must be removed.  Also as tools and fixtures are moved in the cleanroom, the balance of the ionizer is effected.  For both of these reasons and because the control circuitry in the ionizer drifts over time, the ionizers require maintenence.

ESD Training

No ESD control program can succeed without the help and cooperation of the production team.  LBL offers a seminar to teach the people manning your production floor about static charge and how the various steps in a control program work.

ESD Issues for the Senior Manager

LBL understands the complex issues that arise from being in charge of quality management and safety. LBL will work with senior management to consolidate best the practices and drive standardization across the organization.

Specific Problem Solving
