WARNING: Metallic particulates can be especially harmful around electronic
equipment. This type of contamination may enter the data center environment
from a variety of sources, including, but not limited to, raised floor tiles, worn
air conditioning parts, heating ducts, rotor brushes in vacuum cleaners or
printer component wear. Because metallic particulates conduct electricity, they
have an increased potential for creating short circuits in electronic equipment.
This problem is exaggerated by the increasingly dense circuitry of any
electronic equipment.
Over time, very fine whiskers of pure metal can form on electroplated zinc,
cadmium, or tin surfaces. If these whiskers are disturbed, they may break off
and become airborne, possibly causing failures or operational interruptions. For
over 50 years, the electronics industry has been aware of the relatively rare, but
possible, threat posed by metallic particulate contamination. During recent
years, a growing concern has developed in computer rooms where these
conductive contaminants are formed on the bottom of some raised floor tiles.
Although this problem is relatively rare, it may be an issue within your computer
room. Since metallic contamination can cause permanent or intermittent failures
on your electronic equipment, Hewlett-Packard strongly recommends that your
site be evaluated for metallic particulate contamination before installation of
electronic equipment.
