The establishment of a clean room has today become a term of non condition for certain industries and laboratories. Clean room becomes compulsory when biological, pharmaceutical, and scientific industry require enhanced protection against the environment. They meet the principle of contamination control and meet very specific standards. What is a clean room? How do we decontaminate it?

Role of clean rooms

It is a room in which the concentration of particles is controlled. The concentration is controlled in order to minimize the risks of introduction, generation and accumulation of particles. The taking of such precautions generally has an industrial or scientific aim. In addition, data such as temperature, humidity, and lighting are taken into account and must be kept at a precise level. The Cleanroom Certification is given after following all procedure.  The clean room is used in areas vulnerable to environmental contamination and is used for handling substances which may be harmful to humans. This is the reason for the requirement for professionals to wear coveralls. This room contributes to daily sustainable development, by its protective function of the environment.

Decontamination process by professionals

The air entering the clean room is filtered at different levels so that no unwanted items pass through. To avoid early clogging of the filters, the air taken up at the bottom point is treated again in an air handling unit before being returned to the clean room from above. To avoid the concentration of CO2 released by scientists and to compensate for door openings, 30% of fresh airs are added every hour filtered using a process similar to recycling.

It is important to perform Cleanroom Recovery Test to distinguish between overpressure rooms which prevent the introduction of elements such as dust and vacuum rooms which prevent the exit of contaminants such as viruses. The entry and the exits are done by one or more airlocks equipped with air or water shower. The human body, naturally producing a non-negligible amount of contaminants (hair, hair, dead skin cell), wearing a suit before any entry is required. The Clean Room Particle Count is conducted to ensure the neat atmosphere.

Sectors of activity concerned by the clean room

Clean rooms are essential in areas where the presence of particles can distort the quality of manufactured products, endanger the life of humans or compromise the functioning of objects or tools. We distinguish:

• 
  
  
  
  • The agro-food industries whose food products are at high risk and require that they be protected during their manufacture and their conservation. The Fume Hood Certification certificate awarded to hygienic place.
  
  
  • Automotive industries which often encounter the problem of dust encrusting in manufactured parts.
  
  
  • microelectronic industries whose products develop a high sensitivity to contamination
  
  
  • the space industries due to the satellite, the lifetime of which is subject to compliance with certain specific constraints such as temperature, pressure, lighting and particular cleanliness.
  
  
  • Health establishments due to the multiplicity of sources of contamination. These are the personnel, the work tools and the environment. These factors are favourable to the risk of infections which can spread very quickly.
  
  
  
  

Ultimately, the clean room aims to eliminate the risk of contamination when handling substances or products sensitive to the environment. It is therefore desirable to comply with the standards in force in order to avoid a possible disaster.
