Cleanroom: History And Why Cleanrooms Are Preferred in Sophisticated Units

 

An artificially designed, developed & created, environment for the specific purpose of either research, manufacturing and in healthcare sector is categorically known as cleanroom. As the name indicates these cleanrooms are such environments in specific and known boundaries that are meticulously and accurately planned and built, so that the interior of the construction is totally free form harmful gases, bacteria and other pathogens that may interfere with the woks and activities that are intended to take place within. A clean room is made free from such hazardous elements by incorporating certain sophisticated devices and machinery, so that the inner environment is kept totally sterile. Likewise in certain manufacturing industries especially the electronic parts like integrated circuits and allied semiconductor components, it is very much necessary to maintain an absolutely clean and dust free environment which otherwise proves to be quite disastrous.

A clean room not only keeps the internal area sterile but also facilitates the proper functioning and performance of the devices that are installed, as well as the ones that are being manufactured. In case of food industry it is obvious that the products that are manufactured are supposed to be for human consumption and must be manufactured with utmost care. Since even a slight bit of contamination can lead to a wide spread hazard which may be of very high magnitude.

In the health care sector it is very much understood that the places of treatment to the patients must be totally clean and microbe free, which otherwise may lead to other menacing conditions. Industries that need cleanrooms, will usually decide the quality depending on what activity is being done, which will help the sector to define what ISO class is essential for the cleanroom. However, cleanrooms by and large cannot be assumed to be the same or identical in all cases.

Clean rooms that are to be utilized in the production of semiconductors, integrated circuits, complex electronic components and other similar, do not need a need a sterile room especially with respect to microbes and pathogens. Whereas in a biotechnology laboratory or research centre must necessarily be free from microbes, viruses and other bacterial contamination. But in general and as a common rule, a considerably stringent regulation of airborne particulates such as dust and allied materials and surfaces of properties that are brought into the room, scholars, scientists, or other support staff who enter the room, apparatuses, substances, and equipment must be taken into consideration. Structuring and building a cleanroom and making it suitable for carrying out the desired work is usually done by experts like Airtech. Situated in Singapore, the organization, Airtech Equipment Pte Ltd, manufactures and installs exclusive and high-quality hospital door, cleanroom, biosafety level and operating room equipment.

Cleanroom Airflow Mechanism, Airflow Principles And Equipment

 

Maintaining a consistent airflow within the clean room is a matter of expertise and skilful installation and operation. Since the cleanrooms have to be maintained and kept under constant surveillance, for the efficient performance, it has to be equipped with the best possible device and gadgets. Cleanrooms generally have to keep up with a steady flow of particulate free air, which usually is achieved through installing HEPA or ULPA filters that work on the principles of laminar or turbulent airflow.       

In general laminar airflow systems contribute to about more than 75 percentages of cleanroom air filter systems. In these systems, the main components that are employed in the construction of the filters and the hoods is commonly stainless steel, in order to prevent unwanted airborne or object particles from entering into the area. Multidirectional air flow systems use laminar air flow hoods as well as non-specific speed filters in order to keep the air flow constant in a cleanroom.

Nevertheless, there are certain recommendations and limits that are set in for controlling the microbial contamination. This criterion that is set in for the control of level of microbes happens to be very stringent, especially in case of pharmaceutical clean-rooms. Clean rooms in some cases make use of ultraviolet light in order to attain disinfection of the air in a specific area. Ultraviolet devices that beam UV rays are conveniently placed in key points so that the beams scatter and disinfect the entire area by eradicating the infectious elements.

Ultra violet light has been a preferred method of non-contact sterilization that is employed to achieve sterile environments, especially in hospitals and their operating rooms. Being a contactless mode of disinfection the UV drastically reduces dependence on biochemical decontaminators which at times may cause allergies and irritation. Maintaining a positive pressure in a cleanroom is another significant point, by doing so the inside air that leaks out, get out from the chamber rather than giving room to contaminated air entering. Semiconductor manufacturing units follow this aspect because; even minute extents of particulate matter in a possible leakage would spoil the whole system.

Airtech is one of the leading companies in manufacturing, cleanroom equipment of high quality which complies with the global cleanroom technology. Commencing its operation in the year 1984, the company has been supplying cleanroom airflow devices and has also been actively installing and maintaining the devices for peak performances.

The credit of the development of the modern cleanroom was invented by an american physicist, while he created the initial plans for the cleanroom, he emphasised on the problems that earlier cleanrooms had by incorporating continual filtered air stream which was supposed to level out the influx of airborne impurities to a great extent.

Most of the cleanrooms are nowadays equipped with advanced devices like laminar air flow units, clean room air showers, integrated along with certain compounds which are used for eradicating bacterial and other airborne infectious elements.

But however not every cleanroom is the same n terms of application and utility and more than anything the sector in which it is being implemented. While semiconductor manufacturing sector may not be required to be thoroughly sterile and free from microbes and bacteria, but the biotechnology cleanrooms must be totally free from such contaminations, nevertheless a common aspect in all cleanrooms is stringent regulation of airborne contaminations whether particulates or other similar which possible may pose a threat to the activity proposed to be carried out in it. Another aspect that must be taken care of is the outflow of the particulate matter from the clean room to outside. In case of bacteriology labs and research centres where experiments concerned with bacteria and virus are being done then the outflow of such bacterial matter must be totally curbed because of the fact that such leakage of unknown species of virus and bacteria will pose a severe hazard to the society if it spreads.

On the other hand there are certain particular safety measures that are to be taken while entering and working in a clean room, since the environment in the cleanroom must be maintained according to the sector. In a biotechnology cleanroom, the scientists who work on the living microbes and other similar elements, protecting themselves with proper safety suits are a must, at the same time any contaminations from the human body like the hair must also be eliminated. So in order to avoid this, a proper head gear must also be incorporated in the suit.
