Shoe Cover with Conductive Strip to prevent ESD

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, also sometimes referred to as conductive strip shoe covers.

Electrostatic sensitive devices can include computer cards, laser diodes, high-precision resistors, MOSFET transistors which are used to make integrated circuits (IC)s, and light-emitting diodes (LEDs). When exposed to ESD, these types of devices may be rendered useless, thus draining your company’s resources. As such, controlling ESD is imperative not only for ensuring safe and productive workflows, but also for extending the lifespan of your devices and staying within budget.


Even when floors are properly grounded, wearing ESD shoe covers is still a good idea. You can never have too many grounding methods. Some employees may feel that wearing ESD covers can be a nuisance, but in reality, it’s a necessary compliance step and should be viewed as a compulsory aspect of working in a cleanroom environment.
While there are many types of shoe covers available, only certain materials are considered static-resistant. For instance, polyurethane shoe covers may work well for general purpose applications, including medical and food processing environments, but a conductive strip must be included on conductive shoe covers to provide ESD grounding.
When choosing ESD shoe covers to meet your company’s needs, there are a few considerations to be mindful of:

  • Material: Of course, you’ll want to make sure you’re selecting anti-static materials. A non-woven carbon conductive strip can facilitate grounding and prevent ESD. Choosing latex-free options is also advantageous, as the material is a common allergen.
  • Fit: To accommodate wearers of all shoe sizes, a fit of 16” L by 8” W works well. The sturdy strips ensure a snug fit against the shoe to prevent slipping. Not only does this support comfort, it also thwarts ESD effectively.
  • Slip Resistance: There are both regular sole and skid-resistant options available for ESD shoe covers. The skid-free soles are useful in potentially slippery conditions. In cleanroom environments, where surfaces may be more slippery due to their sanitary nature, it may be beneficial to opt for skid-resistant conductive shoe covers to keep your employees safe.

Conductive shoe covers are made from lightweight material to prevent discomfort. In fact, they’re so comfortable that wearers may wind up forgetting they even have them on! In an environment where impurities simply can’t enter the equation, ESD shoe covers are an effective line of defense for keeping your devices safe. They’ll also limit contamination to help keep your cleanrooms and products immaculate.
Both regular sole and skid-resistant conductive shoe covers come in large quantities to last you a long period of time. To browse ESD shoe cover options, visit Harmony Business Supplies online.

How to Breathe Properly with a Face Mask

How to Breathe Properly with a Face Mask

Breathe Safely with Face Masks

In many work environments, face masks are critical for keeping employees safe against breathing in toxins, contaminants, or other harmful particles in the air. While wearing one is second-nature for many associates, if you’re new to the practice, it can feel unfamiliar at first.

Ensuring a proper fit isn’t just essential to your comfort; it’s also critical to keeping you and your fellow employees safe and healthy. Here, we go over the basics of wearing face masks properly to ensure safe breathing.

1. Prep

One aspect of wearing a face mask properly begins before you even put it on. In order to prevent germ transfer in a cleanroom setting, you must first clean your hands using antibacterial soap to keep the mask sterile/clean. If there’s no hand soap within reach, use alcohol disinfectant instead.

2. Place It

face mask placement

Before bringing the mask up to your face, make sure you’re holding it so that it’s facing the right direction. The top portion of the mask should have a bendable edge, which you’ll fit against your nose for a secure seal. Additionally, either side of the mask should have ear loops, which, as their names suggest, will be placed behind each ear. The loops on ear masks are elastic and thus designed to stretch for a comfortable fit with all face shapes. There are also tie style face masks instead of elastic ear loop face masks.

Some face masks also have eye shields to protect your eyes from coming into contact with hazardous fluids or objects. The shield components of these masks should fully cover your eye area. These protective shield face masks also feature fog-resistant panes to ensure clear vision while you’re working.

Once you’ve secured the ear loops or ties, you may also wish to adjust the top edge so that it sits more comfortably and securely against your nose and face. Make sure both your nose and mouth are fully covered by the mask.

3. Double Check

After the mask is secure, check the sides of it for any escaped air. While most designs with ear loops prevent air from escaping, you may have to press the sides against your face with some types of masks for a snug fit.

4. Breathe THIS Way

Finally, and perhaps most importantly, you can breathe with ease once your mask is secured firmly. Yet, it’s important to be mindful of your breath while you have your mask on, as there’s a certain way of breathing used by professionals who wear masks in clean environments. To ensure safe and comfortable breathing, inhale through your nose and exhale through your mouth. Your nose is designed to trap any contaminants in your cilia (the tiny hairs within your nostrils) to prevent them from entering your body. The mouth is better for exhaling, as it helps you release all of your air more efficiently.

5. Remove with Care

Once you’re done wearing the mask, be careful to touch only the ear loops or ties as you remove it. Dispose of it in the designated receptacle and wash your hands again.

Eye Protection for Infection & Hazards

Protecting Your Eyes

eye protection

Isn’t it great to be at your best in everything you do? Whether its work or leisure, it pays to have good eyesight. There’s nothing like hours of diligent hard work at the machine shop with a project that’s waiting for promising pay. Having good vision lessens the risk of injuries and unwanted accidents.

No doubt that you and I want to have the same great moments at work or play, but unfortunately there are some things that can get in our way, particularly with our vision.

Eye injuries in the work place are very common. Thousands of U.S. workers sustain job-related eye injuries every day! Choosing the right eye protection minimizes potential exposure to hazards and infectious diseases via ocular exposure.

Imagine not being able to meet a project’s deadline because a smokey and dusty environment is making it seeing difficult seeing your work on a machine. Or, handling corrosive chemicals in the lab and you have no eye protection on? Can you even imagine medical professionals not using eye protection? Definitively not!

Reasons for Eye Injury

Dust, small particles, smoke, harmful chemicals and ocular diseases can all impact our vision. Chemicals and flying shards are just some of the hazards facing many modern workplaces. Healthcare workers, lab workers and janitorial staff are all prone to infectious diseases from eye exposure.

The 2 major reasons eye injuries/infection happen on the job are:

  1. No eye protection was being worn
  2. The wrong kind of eye protection was worn for the job

Some occupations that have a high risk of eye injuries/infection include:

  • Construction
  • Carpentry
  • Electrical work
  • Maintenance
  • Lab work
  • Health/Dental care
  • Welding

Good eye protection provides a barrier to infectious or dangerous materials getting in your eyes.

Proper eye protection can actually help enhance your performance, improve your eyesight given the right kind of lens, and prevent exposure to harmful particles and harsh chemicals that might permanently harm your eyesight.

All you need to do is to pick the right the right kind of eye protection for your activity.

Picking Proper Protection

Safety Goggles

If you’re in a machine shop, you need a full-face shields, particularly when you are welding. This will keep your entire face from getting exposed to welding heat, sparks and smoke. You can use face shields as well on pretty much any kind of work akin to that of welding or any that keeps your entire face exposed to harmful materials.

In a medical or dental environment, using a full-face shield offers the most protection. Full-face shields cover more of the face and offer more protection from liquids in medical and dental applications.

Safety Glasses

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.
