Growing Number of Clean Rooms
The process of clean room system design involves planning and fabricating the clean room system’s layout and features. In order to make the clean room’s intended design a reality, a wide range of procedures are implemented. In order to accommodate this wide variety of methods, clean room designers have come up with a variety of clean room configurations.
State-of-the art clean rooms achieve high levels of cleanliness and are equipped with high-efficiency features. This level of efficiency can only be achieved by having a carefully analyzed plan. In order to effectively fabricate a clean room, one must put extensive time and effort into planning the clean room design long before the construction phase even begins. In deciding the size and capabilities of a clean room, there are numerous factors that must be considered, such as the maximum personnel capacity. It is crucial to avoid workflow patterns that cause people to retrace their steps; therefore, extra care must be used in drawing out the blueprints. Another important element in the planning stages is carefully considering the types of materials and components that will be used in the clean room’s construction. In designing a clean room, a team of manufacturers and designers will work closely with the client and make note of every specification necessary to ensure that the cleanroom meets the standards of its ultimate destination.
Since clean rooms were first introduced, the clean room industry has experienced a significant amount of growth. Clean rooms have been in high demand from industries that involve dealing with sensitive materials, such as pharmaceutical companies. Due to these companies increasing demand of clean rooms, the clean room manufacturing industry has boomed. This surge in clean room manufacturing has caused governments around the world to create and implement stricter laws and systems of regulations during the processing of numerous medications. The semiconductor industry has also depended on clean rooms to develop their products and maintain production quality. There are numerous companies that even choose the option of building brand new clean rooms over the option of expanding pre-existing spaces. As these industries continue to grow and develop, so will the development and construction of clean rooms.
Various international governmental entities such as the United States Government and the International Organization for Standardization (ISO) have set in place systems of strict regulations and standards for each and every component of a clean room. These systems of standards are crucial in ensuring that the clean rooms are effective in protecting the sensitive operations that are carried out within them. These high-tech operations include electron microscopy, medical testing, nanotechnology development, biotechnology research, and semiconductor fabrication. Carrying out each of these operations require a clean room with varying levels of decontamination, and clean room equipment such as clean room suits (also referred to as bunny suits), personnel decontamination air jets, and filters. Each piece of equipment is vital to controlling the levels of contaminants within a clean room. State-of-the-art clean rooms sometimes feature oxygen supplies for personnel, and are used in research operations that involve studying dangerous chemicals or infectious diseases.
The US FED STD 209E standard system is implemented by the U.S. government, and gives clean rooms a rating based on the number of 0.5 micrometer-sized particulates present per cubic foot within a certain space. The number that the system assigns corresponds to the particle volume. Class 1 clean rooms contain no more than one 0.5 micrometer-sized particle per cubic foot within the clean room’s atmosphere. The layout of Class 1 clean rooms must feature a set of high-efficiency particulate air (HEPA) filters that work in conjunction with other decontamination equipment. The class number increases in correspondence to the permissible level of presence of particles. Class 10,000 clean rooms, for instance, should have no more than 10,000 0.5 micrometer-sized particles per cubic foot. Normal, unfiltered air would be labeled Class 1,000,000 if it were classified using this system. The lower the clean room’s class, the more likely it is to be stationary with hard walls and extensive measures of decontamination and filtration equipment. Clean rooms of a higher class can come with modular features and are more portable. Clean rooms that come with these features can be easily disassembled, reassembled, and moved around, and they provide standard protection. The final design of the clean room, no matter what the design may be, must be carefully considered prior to construction, as it plays a central role in the clean room’s overall functionality.
