 Water leaking due to clogged drainage pipelines on the roof or in the upper floor(s)
c) Preventing water leakage from air conditioning facilities
Because air conditioning facilities commonly involve the use of water, as in coolant
pipelines, humidifying feed water, and water generated as a result of dehumidifying,
they would require measures to prevent water leakage. These measures include:
 Embankments surrounding air conditioning facilities and detection of water
leakage inside the embankments
 Detection of water leakage from water pipes
(4) Fires
a) Fireproofing
Buildings should be made fireproof.
b) Buffer zones
Buffer zones should be provided to avoid the effects of fires in the neighborhood.
c) Effects of fires in the neighborhood
Regarding the effects of smoke and heat caused by fires in the neighborhood,
following circumstances must be reviewed:
 From the standpoint of security, computer rooms and media storage rooms should
be windowless or have double walls to provide protection from fire, etc.
 The air intake duct in the computer room should be capable of being cut off
immediately during outbreaks of fires.
(5) Disasters caused by human neglect
Things to consider with regard to disasters caused by human neglect are summarized
below:
 Markings that clearly point to the presence of a server system should be avoided.
Such signboards would include those attached to a building.
 Computer rooms should be at locations where access can be limited to only
authorized personnel.
 Areas surrounding buildings housing server systems should be guarded by
patrolling, for example.
 Rooftop facilities and ground facilities on the premises visible from outside the
premises should be removed from view with screens or fences.
 Computer rooms should also not be visible externally.
