How to Prevent Cleanroom Contamination


Do you operate a cleanroom? Well, here is a big deal that you need to tightly focus on, or else things can turn out to be menacing at the same time. Just far from the exit strategy, how about the cleanroom contamination? Did you ever think as the foreign agents if entered, can definitively impact, and degrade the quality of your end products that oftentimes get processed in the cleanrooms? Well, to cut the long story short, to have flawless execution, it is indeed important to have complete information about every aspect in the best possible manner. That is how you can manage to get through and implement the cleanroom contamination prevention methods everlastingly. So, to take this guide to your advantage spectacularly, ensure to stick around since we will be covering ‘Major Sources of Contamination in a Cleanroom’ and ‘How to Prevent Cleanroom Contamination’ you need to know about the subject matter constructively. It is now time to tune in!

Major Sources Of Contamination In A Cleanroom

It’s always about avoiding the wrong side of the tracks and identifying what blows up the contamination chances in the cleanroom facility. What is further majestic is – Ensuring a thorough and consistent investigation and observation just to keep things in place. Now, with a positive connotation, this will not ever be terribly wrongful to just focus on foreign agents and keep them away out from your cleanroom facility. And, since we understand the role of cleanrooms in various industries, and how such facilities usually maintain the sustainability and integrity of the drugs’ getting produced and processed within a stipulated time frame, what if we manage to catch the main source that potentially contaminates the facility and figure out further to stopping them entering. Well, if this is supported, this will not take that long to prevent such foreign agents from getting into your cleanroom facilities and processes at the same time. With this being said – Below are the major sources of contamination in any cleanroom that you need to highly take care of.

  • Physical Contaminants
    Anything can come out of nowhere. It is big talk. Thus, to haunt the physical contaminants, it is important to understand the entirety of the source. Thus, physical contaminants can be observed and touched. And the only distinction is – It is not necessary for them to be a part of the product or raw material being used as a part of the cleanroom production facility. Thus, this is not going to turn the heads in no time. Therefore, let us cover the examples of physical contaminants for better understanding.
  • Airborne Contaminants
    These are the materials that mix up in the air but are not initially a part of the air mixture. Thus, you can understand as the materials to be foreign particles which later mix up in the air and become contaminants. Moreover, they are mainly the volatile industrial chemicals such as benzene, ethyl alcohol, and chloroform, and toxic metals such as dust, fumes of lead, chromium, mercury, and so on. To add – Nuisance dust and other particulates as silica can be clubbed in the category by far.
  • Foreign Materials
    Consider these materials to be foreign bodies that could trigger illness or injury in some cases. However, they are oftentimes harmful to various industrial operations too. And the case is quite similar when it comes to cleanroom facilities whereas the foreign materials such as metals, glass particles, fibers, cosmetics, perfume, deodorants, lotions, and clothing can impact the functioning of cleanroom operations in no time.

Chemical Contaminants

When you try to hit hard and operate your cleanroom functioning for drug-related operation, and out of the blue – Any chemical swings and interrupts the entire process within the premises, this is something should be avoided with proper and consistent precautionary measures, or else – You just need to face severe consequences at the end of the day. To burst out the fact – Widespread chemical contaminants can be unwanted chemicals that likely to crack the cleanroom facility, resulting in retarding its functioning and quality of the end-products. This is quite surprising to consider; however, these chemicals put on severe impacts you can ever know about. Furthermore, all you have later at the stage is an unfit drug to use. Thus, does it seem all good and cool in place? Similarly, let’s cover up the examples of chemical contaminants for your reference.

  1. API Of Drugs
    For just an information purpose, API stands for ‘Active Pharmaceutical Ingredient’, and all it means is – The active ingredient which is made available in the medicines. Thus, there are certain APIs of drugs that can trigger and highly impact cleanroom operations and processes by far.
  2. Intermediate Excipients
    As we talked about the APIs which are active ingredients in the medicines, similarly – When it comes to intermediate excipients, they are inactive substances that are mostly used as a carrier of APIs in medicines. So, having an inspection done and removing intermediate excipients become a deal that no one would want to get affected through in terms of keeping cleanroom functioning as seamless as possible.
  3. Intermediate Chemical Reagents
    Consider these reagents having molecular entities that can be compounds or mixtures. And take Grignard, Tollens’, Fehling’s, Collins, and Fenton’s as the reagents which are not at all accepted in the cleanroom facilities at the same time.
  4. Cleaning Agents
    The considerable job of the cleaning agents is to remove dirt, dust, stains, bad smells, and clutter on the surfaces; however, these agents are quite reactive and should not be used inside your cleanroom facility. To share – Detergents, Degreasers, Abrasives, and Acids are agents that you need to know about.

Viable & Microbial Contaminants

When a bunch of right efforts and measures are put down to ensure the strictness and authenticity in any specific setting, it can always result in building a strengthened level of fineness in the industry-related operations and processes. In saying so – Cleanrooms are often tightened up environmentally to ensure that nothing impacts the quality of the drugs being processed during the process. And, to keep things in the momentum, it becomes a dire need to keep contaminants just away entering the facility. Therefore, when it comes to viable & microbial contaminants, these work as the infectious materials that impact the quality and compromise the drugs’ development. To add – Below are the examples you need to press your thoughts on for sure.

  1. Viable Contaminants
    These are the particles/contaminants that do not free-floating in the air mixture. However, they always need some carriers to travel from one place to another. Overall, you can consider viable contaminants to be people, surfaces, air, water, living microorganism, and equipment as carriers.
  2. Microbial Contaminants
    As the name suggests, they are living microorganisms like bacteria, mold spores, yeast, fungi, virus, prions, toxins, protozoa, and their by-product. More importantly, they are brought into the cleanroom facility accidentally in the most non-intended manner possible. Thus, keeping them away will always be a nice choice at the end of the day.

Non-Viable Contaminants

In the most intensifying manner, environmental monitoring daily is highly permissible and regarded. That is how you can get the best jobs done through cleanroom facilities and have the desired end-products processed and produced at the same time. Thus, let’s get through the examples of non-viable contaminants for your reference.

  1. Non-Viable Contaminants
    These are the contaminants that do not possess any living organisms. However, they can be a medium for viable contaminants to get transported from one place to another. In saying so – non-viable contamination can come from paper, equipment, tubing, rust, dust, and disinfectants to just name!

How To Prevent Cleanroom Contamination

As we talked about the major sources of contamination in the cleanroom facilities, and on a large scale, humans have been the major ones you will ever consider. In short, they are the production personnel who work within the cleanrooms for specific operations. Overall, let us discuss the possible ways to prevent contamination in the cleanroom for your reference right below.

  1. If you regularly use beard covers, including hairnets, you can amazingly prevent any contamination getting entered your cleanroom facility.
  2. If it’s not mandatory, ensure to never bring any stuff with you inside the facility since the chances of getting the space contaminated rise up at high rates.
  3. If you just keep your clothes as fit as possible, this will possibly bring down to prevent contamination. Thus, take care of the pointer.
  4. If you learn the right manners to put on and off the clothes in the best possible manner, you can significantly nail things up the right way possible.
  5. If you keep a consistent handwashing habit both before and after entering the cleanroom, this will bring the best outcome for your end-product getting processed and produced in the cleanroom facility.
  6. If you work slowly and gradually without rushing or making movements into the cleanroom facility, this will further promote and prevent contamination level quite low
  7. If you keep up with the habit of talking minimally, it’s highly preferred and a good practice to reduce the contamination ratio by far.
  8. If you smoke, entering the cleanroom shouldn’t be that quick enough since this will increase the cleanroom contamination levels at large.
