Electrostatic discharge (ESD) is an abrupt electrical flow between two electrically charged objects caused by contact between the objects. Lightning exemplifies the concept of ESD. On a smaller scale, the human body is able to carry a charge and cause ESD when touching another charged object.
ESD Safe matting, apparel, gloves, swabs, wipes, and other supplies help ensure your environment is safe from electrostatic discharges (ESD) as much as possible. Very small discharges from static electricity can cause irreparable damage to sensitive components and electronics.
Even tables can carry a charge, causing contaminants to stick to them. Besides airborne particles attaching to surfaces, ESD from humans can damage electronics and semiconductors and can cause electrical failure. ESD Safe products are designed to be non-conductive or to “cage” and dissipate harmful electrostatic discharges. To prevent damage in a manufacturing or lab setting, workers wear ESD gloves or other grounding devices.
Why do you need Static Protection?
With uncontrolled electrical flows, materials can be subject to damage. Quick bursts of lightning, invisible to the human eye, in an instant effect electrical components such as processors. With static dissipative material, instead of a quick burst of lightning, static control products provide a way for the electric charge to dissipate slowly without damage to electronics.
Static Control Products Do 3 Things:
- Prevent static generation
- Dissipate or Shield electrostatic charges
- Protects material from particulate contamination
We only notice ESD greater than 3500 volts; however, an ESD of as little as 20 volts can cause electronic damage.
Electronics that have undergone an electrostatic discharge onto them may experience equipment failure months later. Therefore, to manufacture the highest quality products, ESD Gloves are needed for employees that interact with delicate equipment susceptible to damage from ESD and skin contaminants.
Is Nitrile the best ESD material?
Nitrile is the industry standard for ESD gloves. Found in Biotech, Electronic, and Pharmaceutical manufacturing, nitrile gloves are the industry workhorse. The material is naturally anti-static, puncture resistant, chemical-resistant, and durable, making nitrile the best choice for cleanroom applications. And, researchers find cleanroom nitrile gloves to be more comfortable than other materials because of its “memory” that molds well to the individual’s hand.
Whenever a worker needs hand protection, it is best to choose nitrile as it provides the best barrier protection against cuts and chemicals. However, nitrile is not compatible with aromatic solvents and ketones commonly found in paints and adhesives. For applications involving aromatic solvents, multiple types of glove material must be provided to maximize safety.
Is Nylon ESD Safe?
Nylon is used frequently in electronic manufacturing and handling because of nylon’s dexterity. Nylon is not suitable for cleanroom environments “due to their very high non-volatile residue values”.1
A Higher NVR values correlates to a lower surface resistance, which decreases ESD strength in high humidity environments. The material, generally coated with a polyurethane-coat, reduces static while increasing grip. Workers won’t have to worry about their glove sticking to any material. The polyurethane-coat provides additional puncture resistance and prevents against the glove shedding its material in high volume applications. Additionally, nylon gloves are compatible with all touchscreen devices.
The polyurethane coating maximizes precision and dexterity by retaining touch-sensitivity and by increasing grip without feeling “sticky”.
Is Latex ESD Safe?
No! Normal Latex gloves generate static, so cleanroom environments need material included with an anti-static additive. With an additive, esd safe latex finger cots will prevent static discharge. 5000 Volts become 0 volts in .01 seconds with Suzuki finger cots.
Static Control Goes Beyond
When working with delicate electronic components susceptible to damage from human contamination, ESD gloves are necessary.
However, other static control procedures and devices will provide protection beyond a single employee’s hands. To minimize static electricity and damaging particulates, there are static control products to fully ground employees entering sensitive environments.
When working with sensitive equipment, ESD swabs protect from static damage. No matter your environment, ESD is controllable and damage is easy to minimize with the proper products.

Great care goes into the manufacturing and finishing of optical surfaces, and there are many challenges that can compromise finished product integrity. These optical devices include multiple applications, from consumer to industrial, in a variety of industries such as; automotive, electronic displays, sensors, mirrors, eye-glasses, solar cells, and more. Typically, there are several process steps…
Evolution of Alcohol Wipes & Swabs Do you know the difference between “Pail Wipers” and “Bagged”…? The cleanroom wipes we know today are an evolution of baby wipes. Indeed, pre-wetted wipes used for baby care needs existed long before the cleanroom industry designed their own pre-saturated wipes. While the general concept behind the two products is…
A cleanroom bears its name for a reason: its very purpose is to stay sanitary and free of contaminants to maintain a stable work environment. Because employees handle sensitive equipment and components in these critical areas, keeping contaminants at bay is essential to everyday workflow, and ultimately, maintaining profitability. It may come as no surprise…
Maintaining a cleanroom or controlled environment requires the use of products and tools designed specifically for these areas. When spills and contamination occur in these critical environments, your employees should be able to have cleanroom wipes within reach for the most effective and convenient cleaning possible. Here, we’ll provide a basic overview of cleanroom wipes…
Gloves manufactured for cleanrooms are not manufactured the same as general purpose nitrile or latex gloves. You especially do not want to use food service gloves in your cleanroom. But why can’t you? It might seem obvious, but shouldn’t a high quality nitrile glove be enough? What is the difference between cleanroom latex and medical…
Cleanroom Supplies from Harmony At Harmony Lab & Safety we know that cleanrooms require special attention and products when it comes to maintaining the operation of your controlled environment. If you run or manage a cleanroom, we offer great products designed just for use in cleanrooms of all types. Disposable Apparel for Cleanrooms Many cleanroom…
In many industries, electrostatic discharge (ESD) has the potential to contaminate equipment, products, and environments. One of the most effective ways to prevent ESD is to limit the ways in which it’s created. In cleanroom environments, that starts with grounding your employees. To keep operators grounded and to thwart ESD, employers implement ESD shoe covers,…
Maintaining a cleanroom environment has unique challenges because it’s constantly being exposed to a number of contaminants.
Having the proper cleanroom booties or water resistant shoe covers helps limit the number of contaminants entering your environment. Because operators themselves are the leading source of cleanroom contaminants, outfitting them with the proper disposable attire is critical. Not every environment requires the same type of cleanroom shoe covers, however. Ultimately, the best type for your…
Combat ESD in Sensitive Environments with the Right Swabs Controlling electrostatic discharge (ESD) is an important aspect of ensuring the quality of electrical components throughout manufacturing processes. By nature, some electronics are more sensitive to static than others, which is why many manufacturing plants have special environments like cleanrooms for keeping static at the lowest…
