such as stacking height, floor capacity, structural
clearance, and other obstacles.
EQUIPMENT CAPABILITIES. Use of
potential warehouse storage height may be
restricted by the equipments inability to reach
the full vertical space.
MATERIAL CHARACTERISTICS. The
maximum stacking height depends upon the
material or its packaging. The material
characteristics could cause the stacking height to
TOTAL WAREHOUSE STORAGE SPACE.
The gross storage space within a warehouse
includes the support spaces, aisles, structural
loss, and net storage space.
OCCUPANCY OF NET STORAGE SPACE.
Occupying the maximum net storage spare can
be hindered by ceiling heights, material
characteristics, and elbow room. Sufficient
elbow room should be available to minimize
relocation to make space for new receipts.
Fifteen percent of net available space is
considered an adequate allowance for elbow
room for general supplies.
AISLES. The layout plan must include the aisles
to prevent placement-of material in inaccessible
areas and loss of space.
Items with similar handling requirements should be
stored together when practicable. This will facilitate
storing, caring, and moving of material. The fastest
moving items should be stored in areas easily accessible
to MHE and issue personnel. Loose and unpacked items
issue areas should be adjacent to packing and
processing areas. Slow moving items should be stored
farther from active or processing areas.
The critical factors in developing the layout for
storage operations include the relationship between the
equipment and warehouse dimensions. Although there
are various types and styles of forklift trucks, shelvings,
bins, and racks, few conform to predetermined
standards. Different makes and styles of forklift trucks
require different aisle widths and turning radii. Racks
and shelves have different internal dimensions such as
column and rail thickness.
Several factors should be considered in planning
the layout to support efficient operations. These
include handling classification, special handling
requirements, pallet rack operations, and small items.
There are three basic handling classes of storage in
the Navy system. They include the following:
High cubes and large lots. A limited storage
space is needed for bulk or high cube items or
large quantity of palletized items.
Palletized packaged material. These are items of
various sires, shapes, and configurations that are
stored on pallets.
These items include
instruments, system components, parts, power
tools, and so forth.
Shelf or bin material. These are small items that
can be stored in bins or shelves.
Separation of Elements
Storage spaces used for stowing materials that
require special handling need careful planning of
These are materials that require
environmental control, air conditioning, or security and
are stored separately from general commodities.
Hazardous items should be stored or handled to prevent
hazard to personnel and facility. Strict segregation of
incompatible materials is mandatory. Incompatible
hazardous items, when accidently mixed, could cause
fires, explosions, or give off toxic gases. Sensitive
items require a high degree of protection and control.
Shelf-life items are handled on a first-in, first-out basis.
Pallet Rack Operations
This is the simplest way of handling material.
There is no difference in handling a pallet load of
batteries or a pallet load of electronic circuit cards. The
MHE interfaces with the pallet, and the material on the
pallet does not influence the way the material is
Small items are materials that can be stored in bins
or shelves. In planning the layout, consideration should
be given to the shelvings, bins, and MHE. Always
consider the number and height of the required
