dangerous to store or handle and present real or
potential hazards to life and/or property.
HONEYCOMBING The storing or withdrawing
of supplies in a manner that results in vacant space that
is not usable for storage of other items.
LAYOUT A floor plan showing assignment of
gross space for storage operations and support
MANNED STORAG/RETRIEVAL MACHINE
A variation of the storage/retrieval (S/R) machine
containing an operator cab that permits use of the
machine for order picking.
NET STORAGE SPACE Floor area on which
storage racks and/or bins are erected and on which bulk
material is or can be stored.
ORDER PICKING TRUCK A forklift-type of
machine on which the driver rides up and down on the
mast in an open cab.
The vehicle is specifically
designed for order picking and is not suitable for pallet
PALLET RACKS Metal racks of multiple levels
used for the vertical storage of pallets.
PLANOGRAPH A scale drawing of a storage area
showing the approved layout.
RACK ORDER PICKING Order picking system
in which unopened (full) cases of material are picked
from pallets or pallet rack shelving to fill orders.
RACK SPACE-Any floor area identified as a
specific location and distinguished from bulk storage,
occupied by racks, box pallets, or pallets with metal
superstructures installed when used as permanent
STORAGE/RETRIEVAL (S/R) MACHINE A
specialized machine, usually computer controlled, used
for rapid storage and retrieval of materials.
STRUCTURAL LOSS-In covered warehouses,
this is the gross space that is not usable for storage
because of obstructions. These obstructions include the
frosts, pillars, ramps, door clearances, fire walls, and
installed equipment. Structural loss does not include
the spaces used for aisles.
In open storage, structural losses are spaces taken
up by firebreaks and clearances. Firebreak is a barrier
of cleared or plowed land intended to check a grass fire.
SUPPORT SPACE The storage space used for
receiving, shipping, packaging/preservation,
inspection/identification, packing, crating, assembly,
and offices. It also includes parking areas for material
handling equipment (MHE), battery charging stations,
rest rooms, tool rooms, locker rooms, time clock area,
and break rooms.
SWING ARM SORTER A sorting device that uses
a pivoting arm to sweep an item off a conveyor and onto
the proper discharge lane.
TILT SLAT SORTER A flat surface sorting
conveyor built of pivoting slats. A number of slats
determined by package size are tilted to discharge the
item into the proper lane.
TOTE BOX A small durable container usually
used for order picking and/or shipping of small items.
TOWLINE A continuous chain conveyor used to
pull wheeled carts around a fixed path. The conveyor
may be mounted overhead or in the floor.
The basic resource of any storage operation is the
storage space. The cost of storage operations depends
upon the optimum use of the space and efficient
procedures for the receipt, storage, and issue of
materials. Minimizing cost in storage space can be
obtained by thorough planning for the use of the space.
The different types of storage facilities ashore are
described in detail in the AK3 training manual. The
Warehouse Modernization and Layout Planning Guide,
NAVSUP P-529, provides information in planning the
layout of modem storage facilities.
PLANNING THE STORAGE LAYOUT
A storage area floor plan layout is an excellent
management tool in the effective use of space. The
floor plan shows the divisions of space into storage,
support areas, and aisles. The floor plan also shows the
square footage of gross space, nonstorage space, and the
net space available for storage.
The required storage space is the key factor in
planning warehouses ashore. Several factors are used
in computing the required storage space. These factors
include the following:
l QUANTITY OF INVENTORY. This is the
basic part or conversion factor in estimating the
required storage space.
l CHARACTERISTICS OF STORAGE
FACILITY. This includes storage limitations
