29
Q

Disposal of WP / RP - Disposal Site Considerations

A
  • WP/RP is not to be disposed of on a conventional
    demolition ground
  • WP/RP demolition is to be considered as
    contaminated ground and is to be marked
  • not to be used for the destruction of other natures
    of ammunition
  • The radius of contamination will vary but the area
    to be marked should not be less than 10 m
30
Q

Disposal of WP / RP Special Precautions - Medical

A
  • All personnel are familiar with the immediate
    treatment of WP burns
  • A plentiful supply of water is always to be readily
    available at the demolition area
  • A minimum of 20 L of sterilised water reserved
    exclusively for the treatment of WP burns
31
Q

Disposal of WP / RP Special Precautions - Before firing

A
  • The retired position is to be upwind of the demolition site
  • Open range safety distance is to be applied
32
Q

Disposal of WP / RP Special Precautions - After firing

A
  • Boots and implements are to be passed through a small fire
  • Not to be approached until 10 minutes have elapsed after the last smoke is seen
  • During the clearance phase, members are to remain standing
  • DPCU with sleeves rolled down and fastened at the wrist
  • Current in service gas masks and heavy duty leather gloves are to be worn when approaching the disposal site and while conducting the clearance
33
Q

What are acceptable disposal methods for RP/WP? (5)

A 
PE
CE Primer
Charge Block
Sheet explosive
Lengths of Det cord
34
Q

Subsequent actions after firing WP/ RP? (3)
Wait what time?
What must happen to the ground?
Tools must be passed through ____ and thoroughly ____

A
  • wait 10 mins after smoke has died down
  • Ground to be raked over
  • Pass rakes through fire
35
Q

Can AT pers declare the weapon serviceable after conducting projectile removal?

A

NO!

36
Q

2 distinct categories of stuck projectiles and the description for each

A

Simple Case - No shot travel

Anormal Case - Shot has been shot travelled and has become stuck

37
Q

Stuck Fast.
Whos responsibility is it to deal with:
- Simple Case
- Abnormal Case (2)

A

Simple Case - unit responsibility.

Abnormal

  • SATO/AT/ATO where ejection charge is required
  • Artificer (gun) if no explosive risk
38
Q

What is the purpose of the polystyrene foam former in ejection charges? (3)

A

Centres the PE4 charge
Minimises unequal pressure on the wall of the barrel
Provides an air cushion that slows the initial detonating velocity

39
Q

Stuck Fast

At what distance is the ejection charge placed from the projectile, in the barrel?

A

18 inches

40
Q

Process for Ejection Charge

A
  • Place charge 18 inches from the projectile

- elevate barrel and fill with water

41
Q

What is the purpose of filling the barrel with water for ejection charges?

A
  • water between charge and projectile will cushion fuze

- Water above charge provides a resistant medium against initial pressure

42
Q

What is the maximum width for loose propellant train?

What is the minimum width a point of initiation?

What is the maximum density?

A

1m wide

single stick

50kg / square metre

43
Q

What is the maximum/minimum widths for bagged charges?

A

max 4m wide, reduced to 3 charges

44
Q

What is the maximum density of the train for gunpowder

Where should pers be located (distance / loc)

A
  • 7kg / metre

- 50m upwind

45
Q

Disposal of Detonators

Maximum tiers in a stack?

A

6 tiers high in a stack

46
Q

What must be removed to prep for disposal of HE projectiles by burning?

A
  • Primary and augmenting carts
  • tracers if screw fitted
  • metal fuze well caps
  • Red Phos smoke boxes
  • Exploders or boosters
