This type of warehouse is used for the storage
of highly combustible materials such as oils and
paints. They are built of noncombustible materials
and have firewalls with a 4-hour fire resistance
rating. Their main dependence for fire protection
is placed on an automatic deluge-type sprinkler
system connected to an adequate water supply and
an alarm reporting system.
OPEN STORAGE SPACE
Open storage space is an improved or unim-
proved area designated for use in storing material.
Open improved storage space is an open area that
has been graded and hard surfaced or prepared
with a topping of some suitable material to per-
mit effective materials-handling operations.
Although covered storage is preferred and
necessary for most supplies, materials that are not
readily susceptible to damage by adverse weather
conditions can be accommodated in open storage.
Figure 7-5 illustrates a typical improved open
Open unimproved storage space is an open
area that has not been surfaced for storage pur-
poses. This method of storage is comparatively
inexpensive to operate and maintain and is nor-
mally used for items that are unaffected by
weather conditions. The restriction placed on the
use of materials-handling equipment is one of the
principal disadvantages of this type of area.
For this discussion of warehousing, the focus
will be on those things that the SK normally has
some control over; that is, the actual arrangement
of the stores. Factors in warehousing such as
design, size, and interior characteristics of the
warehouse are usually permanent and cannot be
changed without extensive alteration.
Planning the Storage Layout
Storage space is the basic resource of any
supply department. It is important, therefore, that
the use of this storage space should be as efficient
as possible. This can be obtained only by planning
of storage space. Some of these plans are ex-
plained as follows.
SIMILARITY STORAGE. The basic prin-
ciple of similarity storage is that, as far as
possible, like items should be stored together. For
example, all items in group and class 7510 would
be stored in the same area; or to take it a step fur-
ther, all items in group 75. This method of storage
has some obvious drawbacks. It does not
recognize that some items move faster than others
and should be convenient to the breakout area,
and it also makes little allowance for the size
difference in items within a group. Similarity
storage is more often used by supply centers and
depots where the number of warehouses would
allow this type of storage to be used on a prac-
