detonation
A detonation is classed as an explosion. It is a chemical reaction that propagates with such rapidity that the rate of advanced
of reaction zone into the unreacted material exceeds the velocity of sound in the unreacted material. The rate of advance of
the reaction zone is termed “detonation rate” or “detonation velocity”. When this rate of advance attains such a value that it
will continue without diminution through the unreacted material, it is termed the “stable detonation velocity”. When the
detonation rate is equal to or greater than the stable detonation velocity of the explosive, the reaction is termed a “high-order
detonation”. When the detonation rate is lower than the stable detonation velocity of the explosive, the reaction is called a
“low-order detonation”.

b.
EOD No2: EOD Operator’s assistant, normally qualified to prepare charges, load weapons and drive the RCV.
c.
EOD No3 & 4 Operators: Team members at least qualified on basic EOR.
Deploy ability: To achieve the necessary agility across the spectrum of conflict, the overarching structure of an operational
EOD response can be divided into 3 levels: heavy, medium, light. Although linked to deploy ability and mobility rather than
any particular piece of equipment, this concept is applicable throughout the EOD capability.
•
Heavy. This describes EOD teams that can deploy with all their equipment in their own vehicles, normally bespoke.
The full choice of equipment can improve recovery of evidence and decrease collateral damage. In the maritime
environment, “heavy” applies to deployment with a support vessel, e.g. Mine Counter-Measure Vessels (MCMV). For
the air environment, “heavy” applies to teams configured to conduct rapid airfield clearance from armoured vehicles.
• Medium. This describes EOD teams that have limited lift so can only take an element of the team’s equipment. In
the maritime environment, this would cover deployment by small craft, e.g. medium or rigid inflatable boats. In the
land environment, this could include a quad bike and trailer delivered by helicopter. For the air environment, this may
apply to an EOD team configured for initial entry to a forward operating base (FOB) or deployed operating base
(DOB).
• Light. This describes EOD teams that are required to move to an incident on foot and will therefore need to carry all
their equipment and life support. In the maritime environment, this could be “dive to target”. Teams are the most
mobile but with the least equipment options when considering a render safe procedure, so are likely to be at
increased risk.

fuze, conditions
These definitions are based on the normal operation of a fuze. Safety devices and features, as used I the definitions, are
devices or features which positively prevent fuze arming until eliminated or rendered inoperative. Safety cotter pins, arming
pins, safety blocks, detents, arming wires, safety forks, and the like are examples of positive safety devices and features.
Some safety devices may not be externally visible so that it is not readily determined whether or not they have been
eliminated or nullified. In these cases, the fuze must never be considered unarmed.
a. unarmed – A fuze is unarmed when all of the safety devices and features incorporated in the fuze are present and
functioning so as to prevent the fuze from starting its arming sequence. It is the condition of the fuze when it is safe for
handling, storage, and transportation.
b. partially armed – A fuze is partially armed when any one (but not all) of the safety devices and features incorporated in
the fuze has been eliminated or is not functioning and the fuze has begun its arming sequence but has not completed it.
c. armed – A fuzes is armed when all the safety devices and features incorporated in the fuze have been eliminated or are
not functioning so that the fuze has completed its arming sequence, but has not been subjected to sufficient or proper
forces required to begin the fuze firing sequence.
d. armed and functioning – A fuze is functioning when a special tactical arming and/or firing delay, such as a clockwork
mechanism, chemical action, material creep, etc. Is operating.
e. dud-fired – A fuze is dud–fired when all of the safety devices and features incorporated in the fuze have been eliminated
or are not functioning, and the fuze has been subjected to the force required to begin its firing sequence but has failed to
fire.
f. armed and/or dud-fired – A fuze is armed and/or dud-fired when it has completed its arming sequence, but there is no
positive visual indication that the fuze firing sequence has or has not begun.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze, nondelay
A fuze that functions as a result of inertia of the firing pin (or primer) as the ordnance is retarded during penetration of the
target. The inertia causes the firing pin to strike the primer (or the primer the firing pin), initiating fuze action. This type of
fuze is inherently slower in action than the superquick (instantaneously) fuze since its action depends upon deceleration
(retardation) of the ordnance during impact with the target. Also called “inertia fuze”.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze, retainer
A device designed to restrict the turning of a fuze in a bomb fuze well.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze safety
Two terms that have been commonly used to describe the safety built into a fuze to prevent premature functioning at the
time of employment and to provide the required safety in transportation. One term, “bore safety”, is a term which is strictly
applicable only to fuzes in artillery or mortar projectiles or rockets, and refers to the provision of means to prevent functioning
while in the bore of the gun or in launching tube. Such fuzes are said to be “boresafe”. Detonator safety is the second term
and may relate to fuzes for any application. It refers to the provision of means to prevent functioning of the succeeding
element(s) of the explosive train if the detonator functions while the fuze parts are in the safe position. Such a fuze is said to
be “detonator safe”. In general the terms are interchangeable with respect to artillery, mortar, and rocket fuzes, but bore
safety applies only to those types of fuzes.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze, semi-all-way
A fuze designed to functioning within a radius of 270°of the direction of target impact. Commonly called “semi-all-ways
acting” fuze.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze, spitback
A fuze located in the nose of a shaped charge munitions. When initiated by impact, it produces a detonation which is
directed toward the base element which detonates the main explosive charge.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze, superquick
A fuze designed to function with the least possible delay after impact. The delay is of the order of microseconds. Also
referred to as “fuze, instantaneously”.
[Glossary of EOD terms, American Language Course, Defense Language Institute]
fuze, time
A fuze which is designed to operate after the lapse of a pre-determined time. Time fuzes may be designed to provide an
airburst but the term may also refer to long delay fuzes which function after the weapon strikes the target.

high explosive (HE)
An explosive which normally detonates rather than deflagrates or burns; that is, the rate of advance of reaction zone into the
uncreated material exceeds the velocity of sound in the unreacted material. High explosives are divided into two classes
according to their sensitivity to heat and shock: primary high explosives and secondary high explosives.
Note: Some authorities maintain that high explosives and primary explosives are entirely separate entities.
