Cleaning Procedures and Equipment

conditions in the room. It is essential that any air introduction from outside the
computer room is adequately filtered and conditioned to ensure that it is within
acceptable parameters. These parameters can be looser than the goal conditions for the
room since the air introduction should be minimal. A precise determination of
acceptable limits should be based on the amount of air being introduced and the
potential impact on the environment of the data center.
Because a closed-loop, re-circulating air conditioning system is used in most data
centers, it will be necessary to introduce a minimal amount of air to meet the
ventilation requirements of the room occupants. Data center areas normally have a
very low human population density; thus the air required for ventilation will be
minimal. In most cases, the air needed to achieve positive pressurization will likely
exceed that needed to accommodate the room occupants. Normally, outside air
quantities of less than 5% make-up air should be sufficient (ASHRAE Handbook:
Applications, Chapter 17). A volume of 15 CFM outside air per occupant or
workstation should sufficiently accommodate the ventilation needs of the room.
Cleaning Procedures and Equipment
Even a perfectly designed data center requires continued maintenance. Data centers
containing design flaws or compromises may require extensive efforts to maintain
conditions within desired limits. Hardware performance is an important factor
contributing to the need for a high level of cleanliness in the data center.
Operator awareness is another consideration. Maintaining a fairly high level of
cleanliness will raise the level of occupant awareness with respect to special
requirements and restrictions while in the data center. Occupants or visitors to the data
center will hold the controlled environment in high regard and are more likely to act
appropriately. Any environment that is maintained to a fairly high level of cleanliness
and is kept in a neat and well organized fashion will also command respect from the
room's inhabitants and visitors. When potential clients visit the room they will
interpret the overall appearance of the room as a reflection of an overall commitment
to exslotence and quality. An effective cleaning schedule must consist of specially
designed short-term and long-term actions. These can be summarized as follows:

Daily Tasks

This statement of work focuses on the removal of each day's discarded trash and
rubbish from the room. In addition, daily floor vacuuming may be required in Print
Rooms or rooms with a considerable amount of operator activity.
