When a product becomes prone and sensitive to dust, vapours or other dangerous airborne particles then know that it is high time to use a cleanroom for it and different cleanliness manufacturing operations.
If you are someone who doesn’t know much about a cleanroom then stick a little longer to this article and we will tell you all you need to know about these rooms and what are they made for.
A cleanroom basically is a closed area where there is a very limited or near to zero amount of contamination. These rooms are kept under strict controls and HEPA filters, also known as high-efficiency particulate attenuation filters are used in order to remove the ionizing grids and airborne particles to neutralize the environment of that area. Now on the other hand it is an undeniable fact that no area or cleanroom can stay statically stable and neutral, free of any contamination because work is a dirty process and even a light human movement, vacuuming or lifting can contaminate the cleanroom. Now there is an alternate that can help prevent the dirt and dust in the cleanroom like robotics and zero maintenance equipment but that can be a bit costly and it isn’t always feasible too.
Here are a few things that can be done in order to keep the cleanroom safe from all sorts of contaminations;
- Special furnishes, vacuums and other cleanroom equipment should be used that are made up of non-shedding materials.
- The oils and all other sorts of greases should be tested with FTIR (Fourier transform infrared analysis) in order to identify and prevent any contamination.
- Every product brought into the cleanroom must be deionized and washed with water and other special surfactants.
- For identifying the presence of particles, ultraviolet light source must be used so that the operator can make sure that whatever product is going inside the cleanroom, it is safe of any airborne particles or dust.
- Everyone who enters the cleanroom, he or she must be properly suited in the cleanroom garments, these garments include, gloves, suits, glasses and even shoe coverings.
Cleanrooms should be kept under high maintenance operations and the operator should make regular checks to see if everything is going perfectly fine. The maintenance of the cleanrooms starts from the highest point and goes all the way down to the floor, here all the edges and corners are first vacuumed properly and then damp wiped to ensure proper cleanliness. As far as the floor is concerned, well, it is neither buffed nor waxed, in fact, special DI water and isopropyl alcohol mixture is used to make sure it has no dirt left on it. There are special processes and procedures for every single part that has to be cleaned in the cleanroom. Moreover, special professionals and a highly trained team is assigned to each cleanroom so that there is no stone unturned to keep the cleanroom and it’s equipment cleaned. Also, the use of sprays and lubricants is avoided inside the cleanroom to make sure that no airborne particles develop in the air. Everything, from the room to the equipment of the cleanroom area is kept under special maintenance so that nothing, not even the air of that area gets contaminated.
