Cleanroom Shoe Covers: 3 Factors to Consider

Cleanroom Shoe Covers 3 Factors to Consider

Having the proper cleanroom 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 company will depend on a number of different factors.

To decide which type of shoe covers is best for your cleanroom, take a look at the following key considerations:

Necessary Features 

In order to be considered cleanroom compatible, shoe covers must meet some specific requirements. For instance, basic fabric shoe covers might work for open houses and other general applications, but in cleanrooms, they’re liable to release fibers and compromise your environment. Shoe covers made from non-woven materials, however, are better suited for cleanrooms because they reduce particulate release.

Specifically, spunbound polypropylene is the go-to choice for shoe covers to be used in cleanroom settings. In addition to materials, you’ll also want to consider any other features your shoe covers may need, such as conductive strips. Conductive strip shoe covers are designed to reduce static and will help keep even your most static-sensitive cleanroom devices protected. Water and abrasion resistance are additional features you may need to consider, depending on the type of work performed in your environment.

Comfort & Fit

Donning a pair of shoe covers shouldn’t interrupt an operator’s workflow. Thus, you should seek out shoe covers with a slip-on design to make the process as convenient as possible for employees. It’s also helpful to have shoe covers available in a range of sizes, as your operators likely have different shoe sizes.

Additionally, clunkier shoe styles could make it difficult for operators to wear covers that are too small in size, so it’s always wise to keep larger sizes on hand. That being said, shoe covers that are too large (XL and up) for the wearers with smaller feet may leave too much extra fabric and increase the risk of slips or tears. Take a look at the measurements of the covers when placing your order to make an informed decision before purchasing.

Floor Surface

More than likely, your cleanroom likely has a smooth floor. When coupled with the fabric of shoe covers, smooth floors are notorious for causing slips. To keep your operators safe from slips and falls, you may want to consider shoe covers with added traction. In order to reduce slips, these shoe covers are specially designed with small strips on the sole for gripping the floor better than regular covers, or the entire sole is slip resistant.

They are available in a variety of seizes and are just as safe for use in cleanrooms as other options. Made from spunbound polypropylene, skid-free shoe covers are among the most highly sought-after options for cleanroom operators.

The 4 Most Common Cleanroom Contaminators

The 4 Most Common Cleanroom Contaminators

Maintaining a cleanroom environment has unique challenges because it’s constantly being exposed to a number of contaminants. To stabilize your company’s particle count, identifying your leading sources of contamination is critical. While these sources may vary from one organization to the next, the most common contaminators tend to be similar across most industries.

Here, we discuss four of the most widespread culprits of contamination in cleanroom environments, along with strategies for combating each source:

Cleanroom Operators: While they’re likely the most highly-trained on reducing contamination, operators actually tend to be the leading source of it in cleanroom environments. Employees can compromise your particle count by neglecting to wear the required disposable apparel to maintain your cleanroom environment. Consider how an operator who just left the building for their lunch break might contaminate an environment by neglecting to wear the proper shoe covers, face masks, or other protective apparel. Frequent reinforcement of procedures, coupled with availability of necessary disposable resources, can help to prevent contamination by operators.

HVAC Systems: Inadequate air volume or velocity can impact your environment, exposing it to a rising number of particles. Even if your cleanroom is stable, it’s possible that HVAC systems working below capacity could be pulling in particles from nearby non-cleanroom environments and contaminating your critical areas. To prevent HVAC-related contamination, make sure you’re following the prescribed maintenance schedule for your HEPA filters. A general rule of thumb to follow is to have your pre-filters replaced at least twice per year.

Supplies: Wipes, gloves, and other cleanroom supplies can either help or hurt you in controlling contaminants. If you’re not using the proper shoe covers, for example, you could actually be increasing ESD risks instead of limiting them. The same goes for the gloves and wipes you select. Make sure that the supplies you choose are intended for use in your cleanroom level. For instance, wipes made from a polyester/cellulose blend are ideal for cleaning spills in controlled environments, and many are available for environments of varying classes. There are contaminant-reducing gloves designed specifically for cleanrooms. Using cleanroom documentation, such as paper and notepads, intended for use in cleanrooms is also helpful for reduce particle generation.

Cleaning Procedures: Maintaining a regular cleaning schedule is imperative in cleanrooms, and without strict adherence to procedures and schedules, your risk for contamination increases substantially. In addition to scheduling airborne particle counts, regular inspections should also be performed on work surfaces and in critical places. Also, while general cleanings should be performed frequently, you should also be following a schedule of deep cleanses to keep particle and bacterial counts down.

From cleanroom pens to wipes and apparel, Harmony Business Supplies has everything you need to help control contamination in your company’s cleanroom. Check out our extensive selection of particle-reducing products.

Disposable Apparel in Cleanrooms

Disposable Apparel in Cleanrooms

What is a Cleanroom?

A cleanroom is a controlled environment used in manufacturing, laboratories, scientific research, pharmaceutical, and other industrial applications. Cleanroom environments have controlled, low levels of environment pollutants and contaminates. The cleanliness of cleanrooms are measured by the number of particles per cubic meter in the air. An ISO 1 Cleanroom has only 12 particles per cubic meter, opposed to a typical urban environment that has 35,000,000 particles per cubic meter.

Why do Cleanrooms matter?

When constructing delicate equipment or doing specific scientific research, controlling the environment you are in is paramount to consistent and reliable results and manufacturing.

The modern cleanroom was invented by American physicist Willis Whitfield. Whitfield designed his cleanroom with a constant, highly filtered air flow to flush out impurities. Within a few years of its invention in the 1960s, Whitfield’s modern cleanroom spawned a revolution in high tech manufacturing.

Cleanrooms can be very large. Entire manufacturing facilities can be contained within a cleanroom with factory floors covering thousands of square meters. They are used extensively in semiconductor manufacturing, biotechnology, the life sciences, and other fields that are very sensitive to environmental contamination. There are also modular cleanrooms.

In the healthcare and pharmaceutical sectors, control of microorganisms is important, especially microorganisms likely to be deposited into the air stream from skin shedding.

How do you keep a Cleanroom clean?

Besides regular cleanroom cleaning and maintenance, once a cleanroom is established, personnel must wear special apparel when entering the cleanroom, in order to maintain its particle levels and not generate more particles.

What do you wear in a Cleanroom?

Disposable cleanroom apparel is a popular choice because you don’t have to launder the clothing, you can just toss it out and use a fresh new set, saving time and money.

Disposable Coveralls

Disposable Coveralls help provide overall protection from chemicals and particles in cleanrooms, laboratories, production environments, and more. They also greatly reduce particles generated from skin shedding and personal clothing.

Disposable Coveralls come with attached hood and boot configurations lending themselves to Cleanroom uses, offering more complete covering and protection.

Cleanroom Gloves

Wearing disposable gloves in cleanrooms are required to prevent contamination. Special Cleanroom Gloves are clean-processed and designed to meet the demands of pharmaceutical, medical device, and biotech manufacturers in controlled environments, as well as professionals in lab environments. Cleanroom Gloves are designed to protect both the personnel and the products being made/handled. Wearing Cleanroom Gloves minimizes sub-micron particle contamination of the product or process from the operator’s hands.

Cleanroom Gloves serve a critical function inside a cleanroom or controlled-environment ensuring product quality and safety.

Disposable Shoe Covers & Disposable Boot Covers

Keeps floors clean and safe and prevents tracking dirt and particles into the cleanroom. Wearing shoe covers are essential to maintaining a cleanroom environment.

Cleanroom Face Masks

People are a significant source of contamination in Cleanrooms. Having the right mask for the job, can make a critical difference. Cleanroom Face Masks are used in many different industries and controlled environments, including laboratories, research facilities, aerospace, and semiconductor industries.

Cleanroom Face Masks provide comfort with excellent filtration to avoid contamination in Cleanrooms. Cleanroom Face Masks are engineered for protection against the entry of particulates into a cleanroom or other controlled environments.

Disposable Bouffants & Beard Covers

Disposable Bouffant Caps are worn on the head to provide defense against contamination from hair while remaining comfortable to wear. Bouffant Caps are light weight, strong, durable, and non-linting caps. Keeps hair out of your eyes and out of your work area. These tear resistant bouffant caps are ideal for clean rooms and other sensitive environments.

Disposable Beard Covers are necessary items to have in stock in plants, manufacturing, etc. and are often required by the FDA. After use, employees can simply throw them away. Made of lightweight polypropylene beard covers are comfortable and cool enough for employees to wear all day.

Adhesive Mats in Cleanrooms

Adhesive mats are also used in Cleanrooms. While not an apparel item, adhesive mats play a vital role. Placed on the floor at traffic entrances and exits, this adhesive film instantly captures dirt and particles from the bottom of shoes and equipment wheels, helping to keep the floors clean and maintain the clean environment.

With the right disposable apparel from head to toe, you can prevent contamination in your cleanroom and clean environments and keep your cleanroom operating at the right state, guaranteeing reliable performance for your applications or testing.
