Locate light bulky materials in storerooms with
high overhead clearances for maximum use of
Segregate materials that are dissimilar in type or
Locate frequently requested materials as close as
possible to the point of issue.
Locate shelf-life items in a readily accessible
area to facilitate periodic screening.
Install appropriate stowage aids (flashlight,
paper, and pencil) in spaces where they are
Make aisles at least 30 inches wide, if possible.
Arrange material with identification labels
facing outward to make issue and inventory
Avoid multiple locations for the same item.
If you follow the preceding criteria and guidelines,
you should have no problems in maintaining your
spaces and issuing and inventorying materials.
SPECIAL STOWAGE OF ITEMS
At times, you will have items that require special
stowage. The Naval Ships Technical Manual (NSTM)
and the Hazardous Materials Information System
(HMIS), DoD 6050.5, outline the requirements for
shipboard stowage of dangerous materials and lists the
materials under each classification. We will now cover
the classifications of material and discuss storage
requirements for special types of material.
Hazardous material includes all types of
compressed gases and materials that present a fire
hazard or are otherwise dangerous. Paint and oil
constitute the bulk of material in this category. Paint
and flammable liquid storerooms are normally
provided with alarm and CO2 smothering systems that
can be activated by automatic temperature-sensitive
devices inside storerooms and by manual controls
A flooding system operated
manually outside storerooms is an additional safety
factor. These storerooms are located, when practical,
below the full-load water line, near either end of the
vessel, but not adjacent to a magazine. They are
equipped with watertight doors that must be locked
and dogged when not in use.
Stow compressed gases on the weather deck, and
securely fasten them in a vertical position. Protect the
cylinder valves from accumulations of ice and snow,
and screen the cylinders from direct rays of the sun.
NAVSUP P-485 contains more specific information
concerning handling compressed gas cylinders.
Liquid acid, unless classified as safe material, is
stowed in an acid locker. Acid lockers are leak-proof
and lead-lined boxes, chests, or lockers specifically
designed for stowing bottles or carboys of acid.
Medical acids may be stored in a medical storeroom.
Alcohol should be stowed in a locked container in
the paint and flammable liquid storeroom, to which
only the supply officer (or other officer designated in
writing by the commanding officer) has the key or
Shelf-life material is subject to deterioration.
These items are assigned a shelf-life code listed in the
The code denotes the shelf-life span of
material from the date of manufacture to the date of
disposal, or date of testing according to the inventory
managers instructions to extend the shelf life. Type I
codes (alpha) apply to items for which shelf life cannot
be extended. Type II codes (numeric) apply to items
for which shelf life may be extended.
OTHER REPAIR PARTS
Repair parts should be stored in their original
containers. With todays improving techniques and the
material used in packaging, repair parts may be stored
for a considerable time without damage from dust,
shock, or humidity.
When you are in charge of a storeroom, you are
also responsible for maintaining cleanliness of the
Before you secure each night, sweep the
storeroom and remove all trash. Periodically clean
bins, shelves, ventilation ducts, and fans.
