Airborne Contaminates
Excessive concentrations of certain airborne contaminants can cause the server’s
electronic components to corrode and fail. Take measures to prevent contaminants
such as metal particles, atmospheric dust, solvent vapors, corrosive gasses, soot,
airborne fibers, or salts from entering, or being generated within, the data center.
Avoid locating the data center near print rooms, machine shops, wood shops, loading
docks, and areas that involve the use of chemicals or generate toxic vapors or dust.
Ensure the exhaust from generators or other sources of exhaust do not enter the
intakes of air conditioning systems serving the data center. If the data center must be
located near these hazardous locations, add and regularly maintain adequate filtering
systems.
Note – To avoid introducing airborne contaminates to the data center, unpack the
server outside of the data center and then move the server to its final location.
