Cleanrooms are planned and manufactured using strict protocol and methods. They are frequently found in electronics, pharmaceutical, biopharmaceutical, medical device industries and other critical manufacturing environments. It only takes a quick monitor of the air in a cleanroom compared to a typical office building to see the difference. Class 1000 and Class 10,000 cleanrooms are designed to limit particles to 1000 and 10,000 respectively. A human hair is about 75-100 microns in diameter.
Contamination can lead to expensive downtime and increased production costs.
In fact, the billion dollar NASA Hubble Space Telescope was damaged and did not perform as designed because of a particle smaller than 0.5 microns. Once a cleanroom is built it must be maintained and cleaned to the same high standards. This handbook has been prepared to give professional cleaning staff information about how to clean the cleanroom. Contamination is a process or act that causes materials or surfaces to be soiled with contaminating substances. It is widely accepted that particles of 0.5 microns or larger are the target.
