What Are the Do’s And Don’Ts of a Clean Room?

When you own a clean room, there are some things you can and cannot do while in the clean room. As a clean room manufacturer, Zonsteel recommends that you keep the following Do’s and Don’ts in mind while using the clean room.

✧  Do remove all jewelry and other personal items from the pockets before getting into the clean rooms. This is because these items can have contaminants that can affect the clean room integrity.

✧  Do always use only the approved pens and writing paper while in the cleanroom. This is to ensure that you always have the right materials in the clean room.

✧  If you have to blow your nose or related activity, then consider doing it in the service area or the gowning room. This is to keep the contaminants as low as possible.

✧  It would help if you always used the utmost precautions each time you cough or sneeze

✧  Do not ever wear cosmetics into the clean room. As a clean room manufacturer, Zonsteel understands how the cosmetics can affect the clean room safety and integrity. Such cosmetics include hair products, perfumes, fingernail polish, mascara, and more.

✧  Do not lean on equipment or surfaces while in the clean room. Sometimes the equipment can be costly and you end up breaking it since you decided to lean on one of them.

✧  Do not allow unauthorized personnel to get into the clean room. Such people might not know the best way to carry themselves around while in the clean room, leading to clean room integrity issues.

Any clean room manufacturer will always list the things you can and cannot do while in the clean room. The idea is to help you keep the clean room a better condition to maintain its integrity over a long time. Considering that you are trying to keep it in a particular clean room class, then maintaining its cleanliness is crucial.

What Is the Cleaning Procedure of a Clean Room?

Figure 8: Cleaning the clean room to maintain its integrity

As the name suggests, it is important to have the right clean room cleaning procedure in mind if you hope to maintain the clean room integrity.

As a clean room manufacturer, Zonsteel recommends the following steps to keep in mind if you want to maintain the clean room’s cleanliness.

  1. Ensure that you are using the recommended clean room cleaning agents as recommended by the clean room manufacturer. Deionized water is highly recommended for scrubbing the floors, walls, benches, and more surfaces.
  2. Do not use powders, rags, or scrubs for cleaning the clean room. It is best to get the clean room mops as recommended by the clean room manufacturer. These mops will have woven polyester important for limiting the shedding and tearing on the surfaces as you clean them.
  3. As much as you will be cleaning the clean room surfaces, we recommend that you do not forget about the floors. It is recommended by any clean room manufacturer to clean the floors using a vacuum and the floor also mopped every shift. As for the weekly cleaning routine, make sure to use a cleanroom detergent to remove more dirt in detail.
  4. The windows, walls, and doors need regular cleaning too. Vacuum these parts each day to minimize the particle accumulation and other contaminants on these surfaces. Also, use lint-free wipes if you have to clean them in detail.
  5. The overhead light lenses and the troffers also need regular cleaning. They can be cleaned once a week and then vacuumed dry before using them. This is to ensure the whole clean room always remains clean.

Any clean room manufacturer will outline some of the things you will need to do as the clean room owner to clean and maintain the clean room even better. With the right guidelines, you can be sure that the clean room would serve you better.

Figure 9: A table containing cleanroom classification standards

The clean rooms’ classifications from a clean room manufacturer are mostly based on the square footage and the amount of cleanliness you can expect in the clean room. Below, we want to discuss some of the most common clean room classifications you can get right now.

ISO 5 Clean Room

This is a super clean room classification you will ever get in the market.

This type of clean room must have less than 3,530 particles of size >0.5 microns per cubic meter. As for the air changes per hour, they will be 250 to 300.

Such a clean room will commonly be used in semiconductor manufacturing and the pharmaceutical filling rooms. This is to ensure no contaminants get into the whole manufacturing process.

ISO 6 Clean Room

We can say this is an immaculate cleanroom type of classification. This type of classification needs to have less than 35,200 particles of size >0.5 microns per cubic meter. As for the air changes per hour performance, they will be 180. All the air changes must be HEPA filtered.

ISO 7 Clean Room

For this type, it is classified as a common clean cleanroom. This cleanroom type needs to have less than 352,000 particles of size >0.5 microns per cubic meter. When the particles are in this range, then the clean room would maintain its integrity.

The clean room also needs 60 HEPA filtered air changes per hour to qualify as an ISO 7 clean room. Any clean room manufacturer will give you a few ideas on maintaining this type of air changes per hour.

You will find that this clean room type is common for compounding rooms in the pharmaceutical world, medical device manufacturing, and electronics manufacturing.

ISO 8 Clean Room

Among the different types of clean room classifications, this is the least clean cleanroom classification.

Any clean room manufacturer will classify an ISO 8 cleanroom with less than 35,200,000 particles of size >0.5 microns per cubic meter. As for the air changes per hour, they can be as low as 20.

Even if it is not the cleanest cleanroom, it is still clean enough to have several applications.

This type of clean room would be ideal for e-liquid manufacturing, nutraceutical packaging, and much more. There is no doubt you would still find various applications to still use the clean room.

How Much Does It Cost to Set Up a Clean Room?

For sure, the needs of a project are going to affect the cost of setting up a clean room.

If you want to handle highly sensitive projects, then it means that you have to go for the highest cleanliness in a clean room. This is to ensure that you get the best clean room for the project.

The accessories that you might have to add onto the clean room also matter. Sometimes you might have to set up a fancy air filtration system. In such a case, there is the need to ensure that you use the best accessories to make it happen.

If you are unsure where to begin learning about the cost, then contact a clean room manufacturer such as Zonsteel. Since the company has been in the business almost 20 years, you should have all the information that you need to pick the best clean room for the job.

Do You Need a HEPA Filter For a Clean Room?

Figure 10 :Testing of the HEPA filter

Yes. A HEPA filter is an integral part of a clean room air filtration system. It would be able to help in filtering the air even better on overall. You should never have to worry about the particles getting into the clean room when you have the right HEPA filter set up in the clean room.

As for its lifespan, the HEPA filter can last from three to five years depending on the contamination in the environment and your pre-filters maintenance.

If the pre-filters are not properly maintained, then you will end up with a filter that easily gets dirty and thus its filtration capability quickly downgrades.

The HEPA filter capacity can also decrease with time as the filter media gets saturated, and the static pressure increases.

Always follow the clean room manufacturer instructions on how to maintain your HEPA filter. One good thing about such a filter is that it does not need too much maintenance.

Keep in mind that not all HEPA filters are washable. You might have to replace the filter if you find that it is not washable.

What Materials Are Commonly Used In the Clean Room?

If you are going to use a clean room more often, then there are some things you need to know more about the clean room before buying one.

Depending on the clean room class, the clean room manufacturer will highlight some of the things you can take into the clean room and those you cannot.

If you are using a super clean cleanroom, then such a clean room will have acceptable garments to use while in the cleanroom. The same applies to the solvents you can also use in the clean room.

In most cases, the everyday use personal items are not allowed in clean rooms. This is because these items are likely to have contaminants from the outside that might affect the clean room integrity.

Here is a list of items that the clean room manufacturer would recommend as safe objects to use in a clean room.

✧  Notebooks and paper

✧  Solvents

✧   Plastic containers

✧   Pencils and pens

✧   Adhesives and tape

Cleaning materials such as detergents, wipes, cleaners, mops and more.

What about items that are prohibited? If you are going to own a clean room from a clean room manufacturer, it is best to know what the clean room manufacturer does not recommend to use in the cleanroom.

Here is a list of prohibited items for any clean room classification

✧   Drink, gum, or food

✧   Jewelry and makeup

✧   Cardboard

✧   Leather

✧   Regular writing paper and notebooks

✧   Lubricants, oils, and greases

✧   Velcro

✧   Powders

✧   Unapproved adhesive or tape

✧   Unapproved plastic containers

It is easy to see that it is best to consult with a clean room manufacturer or a professional in the field to know what can go into the clean and what needs to stay out.

How Can You Reduce the Contaminant Levels In a Clean Room?

Figure 11: Wiping the cleanroom floor

Particulate control is important for anyone who wants to keep the contaminant levels in a clean room low.

How people carry themselves around the cleanroom can determine if the contaminants can be kept to a minimum or not. Using the proper garments is the first step a clean room manufacturer would advise when it comes to using a clean room.

The same goes for hygiene and behavior. If everyone is clean and can follow the clean room guidelines, you can have a better clean room.

Here are some additional tips for reducing the contaminant levels in the clean room.

✧    You should walk and work in slow and calm movements. Being fast or hasty sometimes can easily generator particles in the clean room.

✧   Do not smoke or enter the cleanroom immediately after smoking. Even if you like to smoke, it can end up affecting the cleanliness of the cleanroom.

✧   Always wash your hands before getting into the clean room. Many people will do this, but they will not wash them when getting from the cleanroom. Cleaning your hands after getting from a clean room is still as important.

✧   For those with facial hair, it is advisable to use hairnets and beard covers. This is crucial to leave you with a cleaner working space. Your facial hair can carry particles from the outside. If they are covered, it reduces the chances of dropping the particles into the working space.

✧   Look at what the clean room manufacturer recommends for use in the clean room. The aim is to reduce the chances of bringing unnecessary items into the clean room. As such, you would always end up with a better clean room to operate in.
