GROUP A - Group A items are initiating
explosives. These are bulk initiating explosives that
have the necessary sensitivity to heat, friction, or
percussion to make them suitable for use as initiating
elements in an explosive train. Wet lead oxide, wet lead
styphnate, wet mercury fulminate, wet tetracene, dry
RDX, and dry PETN are examples of initiating
explosives.
GROUP B - Group B items are detonators and
similar initiating devices. These are items containing
explosives that are designed to initiate or continue the
functioning of an explosive train. Detonators, blasting
caps, small arms primers, and fuzes without two or
more safing features are examples of Group B items.
GROUP C - Group C items are bulk solid
propellants, propelling charges, devices containing
propellant with or without a means of ignition, and
items that will deflagrate, explode or detonate upon
initiation. Examples of Group C items are single-,
double-,
and
triple-base
propellants,
composite
propellants, rocket motors (solid propellant), and
ammunition with inert projectiles.
GROUP D - Group D items are secondary
detonating explosive substances or black powder or
articles containing a secondary detonating explosive
substance, in each case without means of initiation and
without a propelling charge, or articles containing a
primary explosive substance and containing two or
more effective protective features. Examples of these
items are explosive switches or valves, and other
ammunition items packaged to meet the criteria
established for this group.
GROUP E - Group E items are ammunition that
contains HE without its own means of initiation with a
propulsive charge (other than one containing a
flammable or hypergolic liquid). Examples of these
items are artillery ammunition, rockets, and guided
missiles.
GROUP F - Group F items are articles containing a
secondary detonating explosive substance with its
means of initiation, with a propelling charge (other than
one containing flammable liquid or hypergolic liquid)
or without a propelling charge. Examples are items
initiated by means of a bouchon-firing device,
grenades, sounding devices, and similar items that have
an in-line explosive train in the initiator.
GROUP G - Group G items is fireworks, and
illuminating, incendiary, smoke (including HC) or
tear-producing munitions other than those munitions
that are water activated or contain white phosphorus,
flammable
liquid
or
gel.
This
group
includes
ammunition that, upon functioning, results in an
incendiary, illumination, lachrymatory, smoke, or
sound effect. Examples of these items are flares,
signals, incendiary or illuminating ammunition, and
other smoke or tear-producing devices.
GROUP H - Group H items contains explosives
and white phosphorus or other pyrophoric material.
Ammunition in this group contains filler, which is
spontaneously
flammable
when
exposed
to
the
atmosphere. Examples of these items are white
phosphorus
(WP),
white
phosphorus
plasticized
(PWP), or other ammunition containing pyrophoric
material.
GROUP J - Ammunition in this group contains
both explosives and flammable liquids or gels. This
ammunition contains flammable liquids or gels other
than those that are spontaneously flammable when
exposed to water or to the atmosphere. Examples of
these
items
are
liquid-
or
gel-filled
incendiary
ammunition,
fuel
air
explosive
(FAE)
devices,
flammable-fueled missiles and torpedoes.
GROUP K - Ammunition in group K contains both
explosives and toxic chemical agents. Ammunition in
this group contains chemicals specifically designed for
incapacitating effects that are more severe than
lachrymation. Examples of these items are artillery or
mortar ammunition (fuzed or unfuzed), grenades, and
rockets or bombs filled with a lethal or incapacitating
chemical agent.
GROUP L - Ammunition in-group L is not
included in other compatibility groups. Ammunition in
this group has characteristics that don't permit storage
with other types of ammunition, explosives, or
dissimilar ammunition within this group. Examples of
these items are water-activated devices, prepackaged
hypergolic
liquid-fueled
rocket
engines,
certain
fuel-air-explosive (FAE) devices, TPA (thickened
TEA), and damaged or suspect ammunition of any
other group. Types of ammunition having similar
hazards can be stored together but cannot be mixed with
other groups.
GROUP S - Ammunition in this group presents no
significant hazard. It is designed or packed so all the
accidental functioning hazards are confined within the
package, unless the package has been degraded by fire.
In this case, all blast or projection effects are limited to
the extent they will not significantly hinder fire-fighting
operations. Examples of these items are thermal
batteries, explosive switches or valves, and other
