instructions in NAVSEA OP 2165 cover the preparation,
flow, and use of all the documents required to ship,
receive, and report shipments. Instructions for the use
of ordnance transport equipment, materials to be
transported, division of responsibility for carrying out
inspections, and criteria for accepting or rejecting equip-
ment are also contained in this publication. NAVSEA
OP 2165 contains the general information needed for
you to efficiently, safely, and economically perform the
duties required when shipping ordnance materials.
Department of Transportation Explosive
Hazard Classifications
The Department of Transportation (DOT) has
established explosive hazard classifications for
ammunition and explosives in shipment. DOT defines
explosives as any chemical compound, mixture, or
device whose primary or common purpose is to function
by explosion. Explosives includes, but are not limited
to, individual land mines, demolition charges, blocks of
explosives (dynamite, TNT, C-4, and other high
explosives), and other explosives (gun powder,
nitroguanidine) that have a total weight of 10 pounds or
more. All naval explosives fall within three explosive
hazard classifications-Class A, Class B, and Class C.
These classifications are discussed in the following
paragraphs.
CLASS A.— Class A explosives are chemical
compounds, mixtures, or devices (mass detonating,
spark initiated, or shock sensitive) that constitute a
maximum shipping hazard; for example, black
powder, explosive warheads, nitroguanidine, and
nitrosoguanidine.
CLASS B.— Class B explosives function by rapid
combustion rather than by detonation for example,
rocket ammunition without projectiles, special
fireworks, and starter cartridges for jet engines.
CLASS C.— Class C explosive devices contain
Class A or Class B explosives, or both, but in restricted
quantities. They also have certain types of fireworks.
Examples of Class C devices are electric squibs,
explosive bolts, common fireworks, and small arms
ammunition.
NOTE: Remember, these explosive hazard
classifications apply to ammunition and
explosives during shipment only. They do not
apply to the storage classifications discussed
earlier in this chapter.
Explosives Driver
An explosive driver is often an AO with an excellent
safe driving record, and a person fully qualified
according to Motor Vehicle’s Driver’s Handbook
Ammunition, Explosives, and Hazardous Materials,
NAVSEA OP 2239. To become a qualified explosives
driver, you must meet the qualifications described
below. If you meet these qualifications, you are
certified to drive motor vehicles that transport
hazardous materials (HM).
STATE OPERATOR’S LICENSE.— An
explosives driver must hold a valid state operator’s
license, not necessarily issued by the state in which the
activity is located. This applies to operation of vehicles
both on- and off-station. This requirement is
permanently waived for those personnel stationed
