Class 10,000 Cleanrooms

Class 10,000 Cleanrooms

Of course, you want to keep the rooms in your home clean. A clean home isn’t what we’re referring to when we discuss Class 10,000 Cleanrooms. A cleanroom is a specific type of sterile environment defined by the level of pollutants present in the air.

The first Cleanroom was designed by an American physicist in 1960. Today, cleanrooms are often used in commercial settings. If you need to include one or more cleanrooms in your commercial building project, work with a qualified builder to ensure the rooms are built according to legal requirements.

Requirements for a Class 10,000 Cleanroom

To be classified as a Class 10,000 Cleanroom, an environment must have less than 10,000 particles 0.5 µm or larger per cubic foot of air. Examples of particles that must be kept to a minimum in these rooms include dust and airborne microbes. Other classifications that use this naming system include Class 100 Cleanrooms and Class 1,000 Cleanrooms. In a Cleanroom, there must be a minimum of 45 to 60 air changes per hour.

Certain environments must be kept this clean to avoid contaminating the products used and manufactured within them. To circulate the air according to Cleanroom standards, laminar or turbulent air flow processes to direct the air toward HEPA or ULPA filters. The airflow distribution system is a critical part of Cleanroom design because without an effective way to maintain a particle-free environment, the air in the room can quickly exceed Class 10,000 Cleanroom standards and put the sensitive materials used in the room at risk of becoming contaminated with these particles.

When workers are in Cleanrooms, they must wear appropriate protective suits to prevent the sterile air from coming into contact with their skin and hair and becoming contaminated by the particles that travel on their bodies. These suits include hoods, masks, and boots. Sometimes, workers are required to pass through air showers before entering a Cleanroom.

Cleanrooms often contain the following features:

  • Gowning rooms with airlocks;
  • Stainless steel benches;
  • Gown racks;
  • Stainless steel hands-free sinks;
  • Epoxy or heat-welded vinyl floors;
  • Sealed lighting;
  • Sticky mats for workers to pass over when entering and exiting the Cleanroom; and
  • Air conditioning.

Where are Cleanrooms Used?

Cleanrooms are used in many types of manufacturing environment, such as pharmaceutical and aerospace manufacturing. Other examples of environments that need to be created as Cleanrooms include:

  • Pharmaceutical compounding;
  • Semiconductor non-photolithography;
  • Nanotechnology engineering;
  • Laboratories and manufacturing facilities where military technology is designed and manufactured;
  • University and government research labs;
  • Environments where harmful biological agents, such as bacteria and viruses, are in use; and
  • Optical lens manufacturing.
