PSP Perimeter Security and Physical Barriers 3

Question 1

Which perimeter intrusion detection system (PIDS) technology is MOST susceptible to nuisance alarms caused by wind, animals, and debris?

Accepted Answer

Buried seismic/vibration sensor cable

Answer

Buried seismic/vibration sensors are highly sensitive to ground vibrations from any source, making them susceptible to nuisance alarms from wind-driven debris, animals, and nearby traffic.

Question 2

What is the primary security benefit of constructing a facility with a 'setback' from the property line in addition to a perimeter fence?

Accepted Answer

It provides depth-of-defense by creating multiple security layers with detection time between them

Answer

Physical setback between the property line and the building creates detection time — the distance an attacker must travel after breaching the outer perimeter gives security personnel time to respond.

Question 3

According to ASTM standards, what does an 'F2656 M50 P1' anti-ram barrier rating indicate?

Accepted Answer

The barrier stopped a 5,000 kg vehicle at 80 km/h with less than 1 meter of penetration

Answer

ASTM F2656 M50 P1 means the barrier stopped a 5,000 kg (Class M) vehicle at 80 km/h (50 mph) with 1 meter or less penetration (P1 = Penetration Level 1).

Question 4

A perimeter fence line must pass through a low-lying area prone to flooding. What is the BEST security solution to maintain perimeter integrity during flood events?

Accepted Answer

Install a flood gate or flap gate designed to allow water flow while deterring human intrusion

Answer

Flood gates or anti-intrusion flap gates are designed to allow water to pass freely while physical barriers and sensors prevent human intrusion through drainage openings.

Question 5

What is the recommended maximum spacing between fence posts for a standard 7-foot chain-link security fence to maintain structural integrity under attack?

Accepted Answer

10 feet (3m)

Answer

ASIS and DoD perimeter security guidelines recommend a maximum 10-foot (3m) post spacing to ensure the fence maintains structural integrity and cannot easily be pushed down.
