Brief History of Cleanrooms

A Brief History of Cleanrooms
The first cleanroom identified by historian’s dates back to the mid-19th century, where sterilised environments were being used in hospital operating rooms, although not clean by today’s standards they were none-the less clean for their time. Modern cleanrooms were created during World War 2 where they were created to produce and manufacture state of the art weaponry in a clean and sterile environment.

During the war, US and UK industrial manufacturers designed a colossal amount of hardware such as tanks, airplanes, and guns, this contributed to the success of the war by providing the military with weaponry that was needed at each juncture of the war.

It is known that the HEPA filters were being used throughout cleanrooms by the early 1950s. Some believe that cleanrooms date back to World War I when there was a need to segregate the work area to reduce cross-contamination between manufacturing areas; however no exact date can be found for the introduction of the first cleanroom.

Regardless of when they were introduced into the manufacturing world, contamination was one of the main problems and cleanrooms were the solution. Continually growing and constantly changing for the betterment of projects, research, and manufacturing, cleanrooms as we know them today are recognised for their low levels of pollutants and contaminants allowing for incredible scientific breakthroughs such as Nano Technology etc.

Prior to the creation of modern cleanrooms, early cleanrooms had contamination due to particles and unpredictable airflow throughout the room. With this in mind cleanrooms were created allowing for a constant, high-filtration airflow, which is what is used throughout cleanroom design and construction today.

Particle Testing to Cleanrooms

Cleanrooms come in all shapes and sizes from small laboratories through to large manufacturing buildings. Cleanrooms are used for a variety of industries such as pharmaceutical production, scientific research, software engineering and manufacturing and aerospace engineering.

Though the cleanliness standards may have changed throughout the years, their purpose has always remained the same. Cleanrooms will continue to evolve as more and more research is conducted and air filtration mechanics continue to improve.

Seven things you didn’t know about cleanrooms:

  1. More and more food industries are using cleanrooms to manufacture products that rely on high sanitation standards, thus improving the quality of their products.
  2. Cleanrooms are rated by their class, which is dependent on the number of particles found in the room at any given time.
  3. Did you know that a motionless person standing in a cleanroom still emits more than 100,000 particles per minute? That’s why it essential that the correct clothing is worn at all times.
  4. The top four things that you need to wear in a cleanroom should be a cap, cover/apron, mask, and gloves.
  5. NASA relies on cleanrooms to continue growth for the space program as well
  6. There are many different types of contamination that can contribute to product failure and inaccurate testing and results, such as micro-organisms, inorganic materials, and air particles.
