Structural Problems Raised Floor Structural problems, such as rocking panels and gaps between panels, can cause significant damage to equipment and injury to personnel. Regular inspections for the structural integrity of a raised floor system can help to identify and mitigate problems. Equipment and floor damage can happen when using flooring that does not meet load demands. Load ratings range from 1,000 pounds to 25,000 pounds. Higher panels can be used on heavier areas of a floor where as lower panels can be used on lighter areas.
Metal whiskers Raised floors and other metal structures such as cable trays and ventilation ducts have caused many problems with zinc whiskers in the past, and likely are still present in many data centers. This happens when microscopic metallic filaments form on metals such as zinc or tin that protect many metal structures and electronic components from corrosion. Maintenance on a raised floor or installing of cable etc. can dislodge the whiskers, which enter the airflow and may short circuit server components or power supplies, sometimes through a high current metal vapor plasma arc. This phenomenon is not unique to data centers, and has also caused catastrophic failures of satellites and military hardware.
Structural Problems Raised Floor Many such problems can be attributed to sub-par installation. During installation, attention should be paid to the condition of the subfloor, which should be clean of debris and should be as level as possible. The walls surrounding the raised floor should be as square as possible to minimize the need for cutting raised floor panels and to minimize rocking panels and gaps.
Floating floors as used in sound studios can be either just larger versions of the domestic variety, or much larger constructions with slabs of concrete to keep the resonance frequency down. The manufacture of integrated circuits uses massive floating floors with hundreds of tons in weight of concrete to avoid vibration affecting mask alignment.
