Flashcards in Volume 2 - Unit 4. Protecting Air Force Security Systems (4) Fence questions = nuclear areas Deck (169)
What type fencing is required for all permanent areas containing nuclear resources?
type A fencing
What regulation contains specific fencing requirements?
AFMAN 32-1084, facility requirements
______ must facilitate efficient and effective circulation control.
placement of fencing
What are the primary considerations when determining area boundaries?
1. area size
2. facilities or equipment within the area
only the smallest area necessary to contain the resources and meet operational requirements.
What characteristics must perimeter fences be? (3)
1. chain link
2. two inch square mesh
3. woven nine-gauge steel wire fabric
What gauge must the steel core of perimeter fencing be?
nine-gauge - this only includes the steel core and does not include any coating
What color must perimeter fencing be painted?
non-reflective substance to reduce glare
What serves as a sensor system platform around limited areas?
Because fences serve as sensor systems platforms around limited areas, they must be:
Where is fence fabric mounted with additional bracing and fasteners? (2)
2. gate openings
What can you substitute metal posts on fences with if metal posts are not available?
reinforced concrete posts
Where do you located fence posts, bracing and other structural members?
on the inside (site side) of the fence fabric
From which side of the fence should you secure the fence fabric to the fence posts?
from the inside of the fence fabric
What do you use to secure the fence fabric to the fence posts?
fasteners of tensile strength
What tensile strength should the fasteners (used to secure fence fabric to fence posts) be?
at least equal to that of the fence fabric
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
Who *approves* the depth at which line posts are driven to in areas susceptible to frost heave?
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
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
The approval and certification of drive depth in areas of frost heave must be provided to both:
the unit and the MACJCOM
The minimum height of the top of the fence mesh fabric above the ground surface must be:
What must be installed at the top of each fence?
two 15 inch long outriggers
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
What degree and configuration are the outriggers installed at the top of the fence?
45 degree angles in a "Y" configuration
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
Install ________ between the Y outriggers only if the nuisance alarm rate will stay within acceptable limits.
barbed tape or concertina roll
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
What intervals should you use topping tape?
no greater than every 18 inches
