In Lesson 6 I was struggling to comprehend how the cleanroom floors during my practical were so smooth and was not dirty. This video helped me understand how the cleanroom floors are thoroughly clean after each practical we have in school. This video demonstrated the very specific and orderly method cleanroom cleaners have to perform when ensuring the sterility of the cleanroom so that the contamination from microbes for example have an extremely low chance of occurring.

In lesson 5, i had a hard time understanding the strict attire needed in the clean room. This article helps me understand that we humans have a lot of contaminant. Contaminants like sweat, hair and fabric from the inner clothing can affect the cleanliness of the cleanroom. Wearing gloves, clean gowns , hair nets and shoe covers, This allow us to minimize the amount of contaminants in the clean room.

Cleanroom environments are unlike any other. They come with challenges and requirements specific to their construction, classification, and purpose. Not only do you and your cleaning crew need to have a thorough understanding of the regulations specific to the controlled environment, but so does everyone who enters the room. You need to establish a clear set of rules to limit the amount of particulate in the room, the disruption of particles, and general contamination.

Cleanroom Environment Protocols:

1. Leave personal items outside the controlled environment

If items such as keys, wallets, phones, etc. must be brought into the cleanroom for any reason, ensure they stay concealed beneath appropriate cleanroom garments.

2. Do not eat, smoke, or chew gum inside the cleanroom

3. Do not enter the cleanroom if you're unwell
Germs and other issues associated with physical illness should not be allowed within the cleanroom environment.

4. Don't let anyone enter the cleanroom if they aren't appropriately covered, with clean and gloved hands, face masks, covered shoes, safety glasses, etc.

5. Do not touch your face or hair with gloved hands If you need to tuck some hair under your bouffant or scratch an itch, properly exit the cleanroom to do so and replace your gloves before re-entering.

Why You Need a Cleanroom Protocol

People naturally produce contaminants. Flakes of skin, oils, sweat, and hair are all contaminants within the cleanroom environment and precautions must be taken to limit their reach. Human behavior also has a massive effect on the cleanliness of the cleanroom. Moving too quickly and sneezing or coughing in a controlled env ironment puts the entire environment at risk.

The above list is limited to what those who enter the cleanroom environment should and should not do once inside, but it is by no means an exhaustive list of all cleanroom guidelines and regulations. Simply following this list will help control contaminants in the cleanroom, but it will not actually clean the cleanroom.

I admit the technique shown in this video seemed pretty strange to me at first. 'Why so troublesome?' - the thought i had when i watched it initially.

Oh, we all definitely did clean a table or a surface with a clothe before right? And of course, we wiped the cloth against the surface in random up down left right motions and if the surface becomes clear, we instinctively think that the table is clean - its a habit! which was the main challenge i faced in lesson 6.

In this video, the personnel showed an example of proper sanitization of workplace counter tops, etc. - in which we were tasked to perform in lesson 6's protocol.

As mentioned above, the biggest challenge i encountered was to constantly remind myself that the cleaning of surfaces in a cleanroom involves tedious and meticulous efforts to;

Constantly flip the wipes to its clean side after cleaning a surface.

Overlapping of the second wipe with the first stroke upon second surface cleaning and each subsequent cleaning of surface. 25-50%!

Wipe in a slow steady and downwards/upwards throughout the surface wiping process.

Thankfully though. This video, together with what Dr. Joel explained in class allowed me to reinforce my understanding and to know precisely why is this cleaning technique yet so important. Without knowledge of this cleaning technique, I'd have wiped the BSC in the practical like i always do without sparing a thought about its effectiveness.

Cleaning with this technique CLEANS our surface rather than SPREAD the dirt all over like conventional techniques.

Summary of the video

- Use water for injection quality or freshly filtered demineralized water for the cleaning process

- Add precise amount of water and cleaning substance to the container

- Flush filling lines with the proper cleaning solution

- Gather broken products or dirt without releasing into the air

- Monitor wear and tear on equipment

- Use a one- or two-bucket system depending on the SOP

- Periodically fog the cleanroom and thoroughly clean out any leftover fogging solution

- Record all cleaning tasks in the cleaning log for supervisor approval

In lesson 5, we talked about the practices and the arrangements of certain clean rooms. I was a little confused about how to disinfect the room so that it is free of or minimised from contamination. As we walk in and out, we will bring in certain germs or bacteria from our clothes or on ourselves, and as we touch those materials or equipment, we are spreading bacteria even though we use sanitiser and ethanol to disinfect the places, there will still be places where the bacteria are still found, and it might accumulate the number of bacteria contaminating the room.

This video helped me to have a better understanding of the procedures we have to do to minimise the contamination in the clean room and what we can do to prevent exposing the bacteria and contaminants to the rest of the room after our practical. They showed a step-by-step procedure which is easier to follow as it moves in a direction.

It also talks about being aware of the equipment and its conditions and having to report and record for further actions.

They show a part where they talked about sweeping the products off the floor, especially those toxic products before they are released into the air. I find that is quite an important part especially when handling substances that are more dangerous, as while handling bottles or any agar plates we might have some mishandling e.g dropping or breaking, and this is a great example of why we need to clean it up quickly.
