Electronic hardware is generally sensitive to airborne contaminants. The computer room should be designed to achieve a high level of cleanliness and to minimize airborne dusts, gases, and vapors than can potentially impact performance and reliability of the hardware. Failure to maintain the computer room according to the standard may result in intermittent interference and/or actual component failures.
