Q

What is the order of precedence for RSPs shown in the AEODPS?

Q

List the 8 RSP options.

A

Mark and bypass/avoid - to be dealt with at at later time
BIP - Quickest and safest, high order detonation will occur
Low order technique - shaped charge to clear the fill, high order may occur
SMUD - stand off munitions disposal - ADF authorised service rifle, may cause high order
Remote pull - remotely moved to a safe location for disposal nearby
Remote fuze attack - disable the fuze indirectly
Fuze gagging - prevent fuze functioning
Manual fuze removal - high risk action in extreme situations

Q

What are the 4 categories of RSP?

A

Component isolation/removal - break the explosive train
Power interruption/removal - disable the initiation mechanism or capability for an electrical det to function.

Q

List 11 generic safety precautions when using RPS tools.

A

a. RSP tools that use a blank cartridge immediate area must be free from volatile liquids/gases and loose explosive fillings.
b. Due to stat/EMR hazards, assembly of electrically initiated RSP tools within the weapons loading area of the ICP. Final connection near the UXO location or at the weapon loading area at the EOD technician’s discretion.
c. No radio transmitting equipment within 15 m of electrically initiated cartridge equipment and wires.
d. EOD equipment is only to be operated and employed by trained, qualified and current personnel.
e. Operators must ground themselves before handling electrical cartridges or firing systems.
f. The wearing of ear and ballistic eye protection is mandatory when handling cartridges and loading weapons.
g. The hazards of a UXO must be observed during the removal of the fuse or components when the
equipment is deployed against live ordnance.
h. Normal safety precautions must be observed when handling demolition stores.
i. Equipment that has been modified without approval
from the Designated Logistics Manager is not to be used. If unauthorised modification equipment must be classified as DO NOT USE – XX.
j. Refer to the equipment material safety data sheets, if applicable, for further information.
k. EOD robots are to be turned off when loading electrically-initiated EOD tools.
l. Once EP have been employed on task, be cautious of constant introduction and removal from the task site. The only reason to remove should be due to a positive action or battery replacement.

Q

What is the purpose of ordnance staking?

A

To secure the ordnance from moving when applying techniques by stopping rotational movement and applying downward force. 500kg or less items.

Q

What items are required for ordnance staking?

A

Sledgehammer - no staking if cocked striker hazard held
four stakes - pairs of stakes driven front and rear
4 wooden wedges - to create a downward force with stakes
cordage - lash the stakes to pull together against the wedges

16
Q

How can you stabilise ordnance if staking is not possible?

A

Sandbagging

17
Q

Describe “Gagging” to stabilise ordnance.

A

Immobilising moveable components of a fuzing system to prevent the additional arming or functioning of the fuze.

18
Q

What are some materials that can be used for gagging?

A

wooden wedges
paperclips
cotter pins
wire
tape
straps/belts
nails
plaster of paris
quick set epoxy
mud
rock

19
Q

What is HERO in relation to EMR hazard?

A

A rating of how susceptible EO to EMR. Hazard of electromagnetic radiation to ordnance rating is either unsafe, susceptible or safe. In particular the Electro-explosive devices used in mechanisms or to function devices.

20
Q

What can create or amplify EMR hazards to ordnance?

A

Radio waves - strength and distance
Wire cordage can act as an antenna in lifting equipment
Metal frames, fences and even the human body can act as an antenna
Power lines, microwaves and x-rays emit radio waves
Damage to sensitive component EMR shielding
exposed contacts or contact surfaces

21
Q

What EMR precautions or shielding can the EOD technician apply to EO?

A

Maintain an “as found” state for electrical wiring and components unless detailed technical knowledge of what to short out or open circuit
Exposed contacts, prongs, rings and bands should be covered in insulation tape.
Wrap in foil to insulate from EMR sources - insulate from electrical surfaces, ensure there are no tears of holes
Place in sealed metal box

22
Q

When may a field devised RSP be required?

A

An alternative to destruction for a first seen/undocumented device
Fuzes with untested or no RSP in the AEODPS
When prescribed EOD procedures cannot be applied
When precscribed EOD tools are not available

23
Q

What factors should you consider when applying a field devised RSP.

A

EOD technician to have a detailed understanding of the fuze to develop a method - X-raying the fuze may be essential
Focus targeting on the firing pin of mechanical fuzes
Noticeable fuze breakpoints may be good aim points
For multiple option fuzes prioritise targets to the most hazardous or sensitive components
Electrical operated fuzes consider attacking power source

24
Q

What forces do different RSP tool projectiles bring to bear on ordnance?

A

slug - shearing action
chisel/wedge - parting action
prong - gagging or jamming

25
Q

Why is documentation important after conducting field devised RSPs.

A

Disseminate first hand knowledge of an EOD procedure to other EOD units in the AO, especially for first encountered and no tested RSP items.
Assist developing 60 series manual coverage
Photos, tool placement and written procedures assist in clear and accurate information
