or shipyard, an appropriate work request must be
submitted using the Ships Maintenance and Material
Management (3-M) Manual, OPNAVINST 4790.4.
HAZARDOUS MATERIAL STORAGE
Certain materials with inherent hazardous
properties require special stowage facilities and
Afloat hazardous material
stowage is more restrictive than shore requirements for
damage control purposes. Storage requirements for
each type of material are provided in OPNAVINST
5100.19, chapters C23 and D15, on the Material Safety
Data Sheet (MSDS), and in NAVSUP Publication 573.
MSDSs are available on the Hazardous Material
Information System (HMIS), which replaced the
Consolidated Hazardous Item List (CHIL). The HMIS
is distributed on compact disk-read only memory
(CD-ROM) format only. The HMIS in compact disk
(CD) format contains both the DOD 6050.5L and DOD
6050.5LR. The CD format is issued quarterly. Each
issue contains updates in its entirety.
The HMIS provides the users the information
needed to properly manage hazardous materials. The
system provides Material Safety Data Sheets (MSDSs)
for standard stock numbered items, and a wide range of
information concerning safety, health, packaging, and
labeling. The HMIS gives a Hazard Characteristic
Code (HCC) for each item, which defines the storage
requirements. The HMIS also lists the transportation
information and disposal code for each item. The
disposal code indicates the pretreatment method and
ultimate disposal action prescribed for spilled, spoiled,
or other waste quantities of the item to which it applies.
The HMIS does not contain information for items
procured through open purchase.
The Ships Hazardous Material List (SHML) is a
record of the hazardous material (HM) carried aboard
U.S. Navy ships for which there exists a valid
requirement. The SHML provides ships with the
capability of determining which hazardous materials
are authorized for shipboard use to preclude stocking of
materials for which the ship has no use. Materials
which do not appear on the SHML should be suspect of
being in excess and should not be ordered. A SHML
Feedback Report can be submitted to add items to the
SHML if a valid requirement exists. Quantities of
materials are not provided in the SHML, nor is the
SHML to be used as specific to a ship or ship class. The
SHML is a list of HM that any ship with a valid need is
authorized to have on board. The Material Safety Data
Sheet (MSDS) in the HMIS will state in the first section
whether or not the item is authorized by the SHML.
NOTE: The SHML in CD format has been
incorporated into the Hazardous Material Control and
Management Program (HMC&M). The HMC&M in
CD format contains the SHML, HMIS, and Hazardous
Material Users Guide (I-MUG).
To report SHML inconsistencies or new products,
use the feedback report, NAVSUP Form 1400. This
form is included in the SHML on the CD and an
example is illustrated in chapter 2 of NAVSUP P-485.
If the item to be reported has an assigned national
stock number (NSN) and application data, but not listed
in SHML, submit the report directly to Naval Inventory
Control Point-Mechanicsburg (NAVICP-MECH).
This type of report does not require the commanding
officers (COs) approval. Send an info copy of the
report to the applicable type commander (TYCOM).
The report for items that do not have assigned NSNS
or application data and not listed in the SHML will
require the COs approval. The report must be signed
by the CO and submitted to NAVICP-MECH via the
When procuring nonstandard HM, the request must
include a copy of the approved SHML Feedback
Report. The approved report will serve as required
certification to procure the nonstandard HM that is not
listed in the SHML.
SHIPBOARD HAZARDOUS MATERIAL
Shipboard stowage facilities commonly used for
hazardous items are discussed in the following

OPNAVINST 5100.19, APPENDIX B3-E.
FLAMMABLE LIQUIDS STOREROOMS
The flammable liquids storeroom is normally
located at either end of the ship, below the full-load
waterline, not adjacent to a magazine, and is equipped
with an automatic fire alarm and fire extinguishing
system. This type of storeroom should also be equipped
with incandescent and explosion-proof overhead lights
(protected by lamp guards), with the switch located
outside the compartment, and nonsparking vent fans
