Forensic Science Cleanrooms

The types of impurities that are kept out of the cleanroom through filtering include airborne microbes, dust, chemical vapours, and aerosol particles among others. We have Forensic Sciences Modular Cleanrooms that satisfy the requirements of the international organisation for standardisation (ISO) 14644-1: 2015.

Forensic Sciences Modular Cleanrooms, built to the ISO 14644-1:2015 specification, are classed from 1 to 9. The class of each Cleanrooms can change depending on prevalence and size of air contaminants in the cleanroom. The class 1 range of Cleanrooms, which stands as the greatest, will be evaluated for the lowest frequency and smallest particulate size while the least classification (Class 9), will have a larger air particulate size and higher frequency than all other Cleanroom classifications.

Particle counters are used to gauge the Particles Per Cubic Metre (PPCMM) of Forensic Sciences Modular Cleanrooms to determine their classification. An ISO class 9 cleanroom has a PPCM commensurate with atmospheric air (identical to the environment of a suburb) but with larger particles >5 microns filtered out.

The Class 1 Modular Cleanroom sees to the filtration of much lower air particulate sizes of >0.1 and >0.2 microns, ensuring that the confined space maintains a low level of contamination. The following is an example of this standard of testing.

The evaluation of Class 7 Cleanrooms focuses on an air particulate size of >0.5 with a particulate count of 352,000 at most. If results of the test find that the clean air space does not satisfy these requirements, the Forensic Sciences Cleanroom will be adjusted and retested to meet the standard of the classification.

HEPA and ULPA filters are typically used to maintain the clean air environment in Forensic Sciences Modular Cleanrooms. The use of these filters have passed scientific evaluation and are proven to keep out certain amounts and sizes of air particulates from a cleanroom. Contaminated air goes through Filter Fan Units (FFUs), ensuring there’s positive pressure in the Cleanroom. This positive pressure helps maintain the controlled level of clean air by preventing contaminated air from entering back into the cleanroom through perforated openings.

The type of Forensic Sciences Cleanroom mentioned earlier sees to contamination-free production because only air that goes through the filtration unit is allowed to enter the internal area.

With a Forensic Sciences Cleanroom solution, there’s a low likelihood of product contamination and this is the first stage of securing a pollution-free production area. Putting clean air policies in place that will ensure particulates are not brought in by personnel working in the cleanroom is the next step in developing a clean production environment. This introduction of contaminants can be prevented by the proper use of Cleanroom PPE such as gowning, hair nets and overshoes. Fibres and other potential pollutants entering the cleanroom will be further reduced as a result, allowing production and research to go on without interference. Personnel has to be taught pollution reduction techniques that will ensure required levels of contaminants in the cleanroom are maintained.

Cleanrooms are critical in the production and research processes of industries that require a minimised level of particulate occurrence in order to avoid product contamination.

A Cleanroom is essential for a controlled air space reducing the incidence of particulate contamination via air filtration. The use of Cleanrooms are employed in industries such as science and technology, semiconductors, production, electronics, medical devices, research, food production and more.

At TCA, our main goal is to see to it that you’re provided with the right solution for your needs. Further guidance can be provided if you need assistance with choosing the right standard of Forensic Sciences Cleanroom for your industry.

We only provide Forensic Sciences Modular Cleanrooms that meet the ISO 14644-1: 2015 standard. These Forensic Sciences Modular Cleanrooms are differentiated according to classes – ISO 1-9. A Cleanroom will be classified based on the prevalence and size of the air particulate in the clean air space. To be categorised in the greatest classification (ISO 1), a Cleanroom will be tested for the smallest air pollutant size while Class 9 cleanrooms are tested for larger air particulate sizes and higher quantities.

The Cleanroom validation test method in which these Cleanrooms are classified is by use of particle counters, measuring the Particles Per Cubic Metre (PPCM). The use of particle counters accounts for the number and size of air particulates. ISO 1 rated cleanrooms are evaluated for the extraction of small air particulates >0.1 microns and >0.2 microns whereas an ISO 9 cleanroom, which has a similar PPCM to suburban air, will be tested for the removal of larger air contaminants >5 microns.

Containment solutions are ideal in cases where you have hazardous materials that need to be prevented from making it to the outside air from the cleanroom. Forensic Sciences Modular Cleanrooms can be made to keep production safe by introducing contamination-free air into the work space and contain hazardous materials that come about during production through the use of ULPA, HEPA, or Carbon filters. With our help at TCA, you can have containment solutions installed in your modular cleanroom that will see to the prevention of hazardous substances entering the outside air, keeping you out of the crosshairs of regulators.

Containment solutions can differ due to the fact that hazardous materials are different from each other based on quantity and use of each cleanroom. This goes to mean that each customer’s containment needs can differ from that of others. We will always work closely with you to provide a system that ideally suits your needs.

Airflow and Filtration

Our Cleanrooms are designed to be compliant to the specified ISO 14644-1:2015 grading. With this in mind, we take into consideration the level of air filtration required and the end function of the cleanroom. The level of air filtration required is determined by the air changes per hour (ACH), this determines how many Filter Fan Units are to be used in the cleanroom. What we also determine by the strategic positioning of the FFUs and exhausts is the flow of air around the cleanroom. This can mean the difference between a uni-directional (laminar flow) and a non-unidirectional (turbulent flow) airflow around a cleanroom, potentially leading to a contaminated product. With this in mind, we can greatly increase the number of ACH and control the air flow within the cleanroom.

Filtration of air is controlled by our ultra-quiet, high-efficiency filtration modules. These filtration modules automatically compensate for a build-up of dust and other materials that occur over time within a HEPA/ULPA filter increasing the fan speed to reach the set flow rate. This increases the life of the filter, reducing cost overtime for the end user.

At TCA there is no such thing as a standard modular cleanroom. Each Cleanroom we design is made to fit your unique work conditions and is designed with your needs in mind. We make each modular Cleanroom to order and make you part of the design process.

With TCA you have the option of doing almost anything with a cleanroom design. This means that your Cleanroom can be many shapes and sizes fitting the most obscure of rooms and can have a range of finishes. We have yet to find a design that we could not accommodate.
