These two parameters are, in fact, fundamental for an up-to-standard production , which essentially takes place in four phases : Design : consists of the concrete analysis of the project and defines a series of factors, ranging from the requirements that the sterile environment will have to respect to the type of artefacts that will have to be protected within it, from the possible ways of contamination to the protection of the staff operating within the spaces, from the compliance with specific directives and technical standards to the detailed technical requirements relating to the preparation.

Development : this is the part relating to the actual creation of the sterile environment, which takes place through the collaboration of technicians and engineers with the ultimate goal of identifying the best solution to meet the needs of the project.

The key parameter of the purity class is one of the fundamental guidelines for the production of the correct elements such as wall systems, ceilings, floors, floodgates, but also electronic components and air conditioning technology to be installed inside these spaces.

Implementation : the implementation of the sterile environment takes place through the verification and testing of the entire technology.

If the results reflect the necessary prerequisites and meet the correct reference standards, the plant will proceed to the homologation phase. Monitoring and maintenance : the monitoring phase and any maintenance work carried out on a sterile environment must be guaranteed with consistency and regularity.

Similarly, the cleanliness of the sterile environment will also be carried out in accordance with specific rules and should only be carried out by specialised personnel.

Sterile environments -

It is well isolated, well-controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research, and in industrial production for all nanoscale processes, such as semiconductor manufacturing.

A cleanroom is designed to keep everything from dust, to airborne organisms, or vaporised particles, away from it, and so from whatever material is being handled inside it.

A cleanroom can also prevent the escape of materials. This is often the primary aim in hazardous biology and nuclear work , in pharmaceutics and in virology. Cleanrooms typically come with a cleanliness level quantified by the number of particles per cubic meter at a predetermined molecule measure.

The ambient outdoor air in a typical urban area contains 35,, particles for each cubic meter in the size range 0. By comparison an ISO level 1 certified cleanroom permits no particles in that size range, and just 12 particles for each cubic meter of 0. Semiconductor facilities often get by with level 7 or 5, while level 1 facilities are exceedingly rare.

The modern cleanroom was invented by American physicist Willis Whitfield. Whitfield designed his cleanroom with a constant, highly filtered air flow to flush out impurities. The majority of the integrated circuit manufacturing facilities in Silicon Valley were made by three companies: MicroAire, PureAire, and Key Plastics.

These competitors made laminar flow units, glove boxes, clean rooms and air showers , along with the chemical tanks and benches used in the 'Wet Process' building of integrated circuits.

These three companies were the pioneers of the use of Teflon for airguns, chemical pumps, scrubbers, water guns, and other devices needed for the production of integrated circuits. William Bill C. McElroy Jr. McElroy also wrote a four-page article for MicroContamination Journal, wet processing training manuals, and equipment manuals for wet processing and clean rooms.

A clean room is a necessity in semiconductor manufacturing , rechargeable battery industry, the life sciences , and any other field that is highly sensitive to environmental contamination.

Cleanrooms can range from the very small to the very large. On the one hand, a single user laboratory can be built to cleanroom standards within several square meters, and on the other entire manufacturing facilities can be contained within a cleanroom with factory floors covering thousands of square meters.

Between the large and the small, there are also modular cleanrooms. With such a wide area of application, not every cleanroom is the same. For example, the rooms utilized in semiconductor manufacturing need not be sterile i. Vice versa, operating rooms need not be absolutely pure of nanoscale inorganic salts, such as rust , while nanotechnology absolutely requires it.

What then is common to all cleanrooms is strict control of airborne particulates , possibly with secondary decontamination of air, surfaces, workers entering the room, implements, chemicals, and machinery. Sometimes particulates exiting the compartment are also of concern, such as in research into dangerous viruses , or where radioactive materials are being handled.

First, outside air entering a cleanroom is filtered and cooled by several outdoor air handlers using progressively finer filters to exclude dust.

Special lighting fixtures, walls, equipment and other materials are used to minimize the generation of airborne particles.

Plastic sheets can be used to restrict air turbulence, if the cleanroom design is of the laminar airflow type. Air temperature and humidity levels inside a cleanroom are tightly controlled, because they affect the efficiency and means of air filtration.

If a particular room requires low enough humidity to make static electricity a concern, it too will be controlled by e. introducing controlled amounts of charged ions into the air, using a corona discharge. Static discharge is of particular concern in the electronics industry, where it can instantly destroy components and circuitry.

Equipment inside any cleanroom is designed to generate minimal air contamination. The selection of material for the construction of a cleanroom should not generate any particulates, hence monolithic epoxy or polyurethane floor coating is preferred.

Buffed stainless steel or powder-coated mild steel sandwich partition panels and ceiling panel are used, instead of iron alloys prone to rusting and then flaking. Corners like the wall to wall, wall to floor, wall to ceiling are avoided by providing coved surface and all joints need to be sealed with epoxy sealant to avoid any deposition or generation of particles at the joints, by vibration and friction.

Many cleanrooms have a "tunnel" design, in which there are spaces called "service chases" which serve as air plenums that carry the air from the bottom of the clean room to the top so that it can be recirculated and filtered at the top of the clean room.

Cleanrooms maintain particulate-free air through the use of either HEPA or ULPA filters employing laminar or turbulent air flow principles. Laminar, or unidirectional, air flow systems direct filtered air downward or in horizontal direction in a constant stream towards filters located on walls near the cleanroom floor or through raised perforated floor panels to be recirculated.

Stainless steel or other non shedding materials are used to construct laminar air flow filters and hoods to prevent excess particles entering the air. Turbulent, or non unidirectional, air flow uses both laminar air flow hoods and nonspecific velocity filters to keep air in a cleanroom in constant motion, although not all in the same direction.

The rough air seeks to trap particles that may be in the air and drive them towards the floor, where they enter filters and leave the cleanroom environment. US FDA and EU have laid down guidelines and limit for microbial contamination which is very stringent to ensure freedom from microbial contamination in pharmaceutical products.

In addition to air filters, clean rooms can also use ultraviolet light to disinfect the air. Their use in other clean rooms may increase as equipment becomes more affordable. Potential advantages of UV-based decontamination includes a reduced reliance on chemical disinfectants and the extension of HVAC filter life.

Some cleanrooms are kept at a positive pressure so if any leaks occur, air leaks out of the chamber instead of unfiltered air coming in. This is most typically the case in semiconductor manufacturing, where even minute amounts of particulates leaking in could contaminate the whole process, while anything leaking out would not be harmful to the surrounding community [ citation needed ].

The opposite is done e. in the case of high level bio-laboratories that handle dangerous bacteria or viruses; those are always held at negative pressure , with the exhaust being passed through high efficiency filters, and further sterilizing procedures.

Both are still cleanrooms, because the particulate level inside is maintained within very low limits. Some cleanroom HVAC systems control the humidity to such low levels that extra equipment like air ionizers are required to prevent electrostatic discharge problems. This is a particular concern within the semiconductor business, because static discharge can easily damage modern circuit designs.

On the other hand, active ions in the air can harm exposed components as well. Over the last several years, they have carried out their Warehouse Labeling Gram Stains in the Lab Alexander Goldberg, Ph.
