1

What type fencing is required for all permanent areas containing nuclear resources?

type A fencing

2

What regulation contains specific fencing requirements?

AFMAN 32-1084, facility requirements

3

______ must facilitate efficient and effective circulation control.

placement of fencing

4

What are the primary considerations when determining area boundaries?

1. area size
2. facilities or equipment within the area

5

T/F Fence
only the smallest area necessary to contain the resources and meet operational requirements.

true

6

What characteristics must perimeter fences be? (3)

1. chain link
2. two inch square mesh
3. woven nine-gauge steel wire fabric

7

What gauge must the steel core of perimeter fencing be?

nine-gauge - this only includes the steel core and does not include any coating

8

What color must perimeter fencing be painted?

non-reflective substance to reduce glare

9

What serves as a sensor system platform around limited areas?

fences

10

Because fences serve as sensor systems platforms around limited areas, they must be:

stabilized

11

Where is fence fabric mounted with additional bracing and fasteners? (2)

1. corners
2. gate openings

12

What can you substitute metal posts on fences with if metal posts are not available?

reinforced concrete posts

13

Where do you located fence posts, bracing and other structural members?

on the inside (site side) of the fence fabric

14

From which side of the fence should you secure the fence fabric to the fence posts?

from the inside of the fence fabric

15

What do you use to secure the fence fabric to the fence posts?

fasteners of tensile strength

16

What tensile strength should the fasteners (used to secure fence fabric to fence posts) be?

at least equal to that of the fence fabric

17

What can you do with line posts for fences in areas susceptible to frost heave?

line posts may be direct driven instead of set in concrete

18

Who *approves* the depth at which line posts are driven to in areas susceptible to frost heave?

local engineers

19

Who *certifies* the depth at which line posts are driven to in areas susceptible to frost heave? (2)

1. AF civil engineering support agency
2. AF facility structural engineer

20

The approval and certification of direct driven line posts in areas susceptible to frost heave must ensure the recommended direct drive depth: (2)

1. mitigates occurrences of frost heave due to deep freezing conditions
2. mitigates occurrences pull out/overturn due to wind loading

21

The approval and certification of drive depth in areas of frost heave must be provided to both:

the unit and the MACJCOM

22

The minimum height of the top of the fence mesh fabric above the ground surface must be:

seven feet

23

What must be installed at the top of each fence?

two 15 inch long outriggers

24

Two 15-inch long outriggers are installed at the top of each fence. What is placed on those outriggers?

each outrigger has three strands of barbed wire

25

What degree and configuration are the outriggers installed at the top of the fence?

45 degree angles in a "Y" configuration

26

Which nuclear sites are exempted from having outriggers at the top of the fences?

nuclear sites employing approved taut wire sensor (TWS) system or equivalent approved detection system at the top of the fence

27

Install ________ between the Y outriggers only if the nuisance alarm rate will stay within acceptable limits.

barbed tape or concertina roll

28

When should you install barbed tape or concertina roll between the Y outriggers on top of a fence?

only if the nuisance alarm rate will stay within acceptable limits

29

What intervals should you use topping tape?

no greater than every 18 inches

30

Where are top rails installed? (3)

1. top of fence fabric
2. below the outriggers
3. taut wire sensor (TWS)
