Q
  1. What is WT?
A

Wait time

Allows capacitors to bleed down in electrical fuses, self-destruct and self-neutralizing ordnance to function, or functioning of slow burning pyrotechnic fuses

20
Q
  1. What are the WT for UXO?
A

Pyrotechnic Delay: 1 HR WT

Projected electrical fuses: 1 HR WT

Guided missiles: 3 HRS WT

Bomb fuses: 24 HRS WT

21
Q
  1. What are the safety rules of CHEM?
A

Stay upward of suspected chemical munitions

Proper PPE, and use detection device

600m upwind hazard
2000m downwind hazard

22
Q
  1. What is minimum distance for Chemical?
A

600m upwind

2000m downwind hazard

23
Q
  1. What is WP?
A

White phosphorus

24
Q
  1. What are the safety rules of WP?
A

Do not crush or break WP residue

Exposure to air will reignite

Submerge item in mud or wet sand

PPE (Hand and eye)

25
25. What are the safety rules of Fire?
Do not allow heat or spark producing material in area Some munition contains pyrophoric liners Have proper PPE and fire fighting equipment
26
26. What is CW?
Clockwork Machinery (fusing) containing a train of wheels/gears of a small size designed to operate for a preset amount of time
27
27. What is C/S?
Cocked Striker (C/S) A striker/firing pin/detonator that is held in a ready to fire position under spring tension
28
28. What are the safety rules of C/S?
Do not move, jar or strike a UXO with a cocked striker
29
29. What is BT?
Booby Trap Concealed and set to explode when an unsuspecting person touches off its firing mechanism as by stepping or moving a harmless looking OBJ *** Enter and Exit on same cleared path***
30
30. What is MAG?
Magnetic An ability to attract Explosive body having the property of attracting iron and/or producing a magnetic field external to itself
31
31. What are the safety rules of MAG?
No movement of ferrous metal Do not approach with metallic objects Do not turn on or off power lines Do not move UXO
32
32. What is SEISMIC/ACOUSTIC?
SEISMIC A sensor that can be used to detect very low frequency vibrations ACOUSTIC A sensor that is designed to be actuated by sound emitted from a specific target
33
33. How should you approach an explosive?
45 degree angle from the rear
34
34. How long should you spend on target? (TOT)
Minimize time on target IOT reduce hazards to personnel and equipment
35
Two parts of disposal of UXO
Disposal of Incident | Final disposition
36
Disposal of Incident
The action taken to render a hazardous situation safe, either: Render safe procedures Blow in place
37
Final Disposition
What is left after rendering a hazardous situation safe BIP is disposal and final disposition at the same time
38
Most preferred and safest method of disposal
The preferred and safest method of disposal is to destroy UXO in its original position (BIP) There is no RSP (EOD only) procedure needed.
39
Definition of Render Safe Procedures
Render safe procedure (RSP) is the removal of an item that would not allow the munition to function (EOD only)
40
Is RSP a disposal?
No RSP is not a disposal, a BIP is not a procedure
41
Is BIP a procedure?
No RSP is not a disposal, a BIP is not a procedure
42
Safety/PPE Considerations/Precautions
*Verbatim* When conducting UXO disposal, ballistic helmet, Level III body armor, approved hearing protection, and ballistic eye protection must be worn
43
Basic considerations
``` There is no "safe" procedure Improvised procedures may be used Do not take tools/eq near item until it can be determined that it is not magnetically functioned UXO operations should be planned Limit personnel exposure to site ```
44
How should you treat unknown explosives?
Treat as the most hazardous type, with the most hazardous features, under the most hazardous condition
45
How many people must be involved in UXO operations?
2 | Short-stop halfway for communication
46
Battle drill for UXO
Clear Cordon Control Call EOD
