Answer 11

Inhabbited building distance

Question 12

rockets and misssle to be regarded as self propelled

Answer 12

Always point self propelled at the wall (Where there is tranvers) NOT AT the door

Question 13

Advantages of a travers?

Answer 13

Can be used to increase quantites of stored muntion
reduces the distance between two ESH

Question 15

What happens if the traverses are to close to the PES?

Answer 15

The explosion undermines the travers

Question 16

from the furthest point from the PES to the travers what angle and distance through the travers does a line need to go?

Answer 16

Go through at least 1m from 2 degress at a higiet of 0.6 m and 2.4m from the top of the stack

I - Double slope earth mound
II - Single slope vertical face earth mound ( or partial vetical face mound)
III- steep double slope eath mound or chilver type
IV - bunker building or combined traverse this includes fully buried building not more than 600mm below ground level
V - wall traers contrcuted of brick reinforce contrete and compostie contsruction
VI - natural features of site hillock these are to be the same as type I at a minumin size

Question 23

What is aggregation?

Answer 23

Mixing of HDs 1.1-1.6

Question 24

What is unitization?

Answer 24

Partition of explsoives by divindng walls, delay in communcation, onkly applicable when stored in orginal packaging

QD = 50m
LEss then 10kg non frag
No LOS between stack
minium of 1m between stacks

Question 25

What is grouped PES?

Answer 25

When IMD are to small for liencings you group them as one PES You can group CGs that cant mix in the two seperate buildings. allows more freedom IF diffenret buildings you take the lowest value and use it for both

Question 26

What is a compartmented building?

Answer 26

Seperate rooms no connecting doors at least meduim wall R&I bay needs to be heavy wall indivudal bay is Individual PES 5 Units 5 liences

Question 27

Ristrictions on compartmented buildings?

Answer 27

Compartments containing 1.1 1.2.1 and 1.3.3 cannot be adjacent two bays containing HD 1.1 have to be trhee buffer bays buffer compartments may be empty or contain inert items or contain HD 1.2.2 1.3.4 or 1.4 1.1 to 2500kg 1.3.3 5000kg 1.2.1 1.2.2 1.3.4 to be liencesed capacity OQD will dicate if less than max aggregation to be in each bay seperatley ( Dont forget they will change the HD or CG depedning on what you mix)

Question 28

What is ESM?

Answer 28

Explsoive safeguarding map

Question 29

Whats the difference between registered and unregistered ESM?
