Question 21

HD 1.1

Answer 21

Blast

Contains ammunition which presents a mass explosion
hazard, which will produce severe structural damage to
surrounding buildings in the immediate neighbourhood.

The severity of the damage is dependent upon the
quantity of explosives involved and the distance of the
buildings from the explosion site.

Blast and high velocity fragments are the major hazards
although there may be a danger from heavy fragments
propelled from the structure in which the explosion
occurs.

Question 22

HD 1.2 Projection Effects

Answer 22

Contains ammunition which has a projection hazard
but not a mass explosion hazard.

The explosion will result in items burning and exploding
a few at a time. Fragments, firebrands and
unexploded items may be projected in considerable
numbers, some of which may explode on impact and
so propagate fire, and/or explosion.

Blast effects will be limited to the immediate vicinity of
the exposed site.

Question 23

HD 1.2 Subdivisions

Answer 23

HD 1.2.1
HD 1.2.1 comprises those munitions that contain a
high explosive charge and may also contain a
propelling or pyrotechnic charge. These items will have
an individual NEQ greater than 0.73kg.

HD 1.2.2
HD 1.2.2 comprises those munitions that contain a
high explosive charge and may also contain a
propelling or pyrotechnic charge. These munitions will
have an individual NEQ equal to or less than 0.73kg.

Question 24

HD 1.3.3 Producing a mass fire effect.

Answer 24

Consists of the more hazardous items of HD 1.3 and are
more likely to be bulk packed gun propellants which
produce a fireball with intense radiant heat, firebrands
and some fragments.

The firebrands may be only small glowing particles of
packaging materials but sometimes there may be
massive fiery chunks of burning propellant.

Ammunition that gives rise to considerable radiant heat.

Question 25

HD 1.3.4 Not producing a mass fire effect.

Answer 25

Consists of the less hazardous items of HD 1.3 that produce a moderate fire with moderate projections and firebrands.

Question 26

HD 1.3 Fire and Radiant Heat

Answer 26

Contains ammunition which has a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard. Items in this division may explode but do not usually form dangerous fragments. Firebrands and burning containers may be projected. It includes some items which burn with great violence and intense heat emitting considerable thermal radiation (mass fire hazard) and others which burn sporadically.

Question 37

Types of ammunition sub batched:

Answer 37

Fixed ammunition. Semi fixed ammunition. Separate loaded ammunition. Mortar ammunition.

Question 38

HD 1.4

Answer 38

No Significant Hazard Contains ammunition with only a moderate fire hazard which will not contribute excessively to the fire. The effects will be largely confined to the package, however the external fire may cause the package to be degraded such that it will not entirely contain the effects of the ammunition. No fragments of appreciable size or range are to be expected. An external fire will not cause a mass explosion of the total contents of the package, irrespective of the number of items in the package.

Question 39

HD 1.5

Answer 39

Blast Contains ammunition which although potentially mass explosive, very insensitive: Usually when conditions of extreme confinement plus large quantities are involved. Ammunition in this division is confined to certain types of bulk explosives which are so insensitive that there is very little probability of a transition from burning to detonation under normal conditions of storage and transport.

Question 40

Position of Identification package
