/ ALREADY GRADED A+
Which radiation hazard category describes the danger of detonation or device failure resulting
from exposing electrically initiated devices (EIDs) to EMR? - ANSWER--HERO
Which type of LPS is identified in the image below? - ANSWER--Mast
How many down conductors are required for a building with a perimeter length of 425 feet? -
ANSWER--WRONG 3
Which publication provides detailed information on Hazards of Electromagnetic Radiation to
Ordnance (HERO)? - ANSWER--AFI 91-208
Which two publications provide detailed information on lightning protection systems? -
ANSWER--DA PAM 385-64
NFPA 780
Which statements about lightning protection are true?Select all that apply. - ANSWER--
Lightning can detonate munitions and explosives.
Lightning seeks the path of least resistance to ground.
Lightning cannot be stopped or prevented.
Which statement is true about a mast LPS? - ANSWER--Each mast must have two paths to
ground.
,A 30-foot tall building is protected by a catenary system. How far from the building should the
masts be placed? - ANSWER--at least 6 feet
Which LPS uses air terminals and conductors mounted directly to the structure? - ANSWER—
Integral
Why does the wooden mast have an air terminal on top and two down conductors running its
entire length? - ANSWER--The wooden mast is not electrically conductive
Which of the following is NOT a requirement for air terminals? - ANSWER--Air Terminals must
be at least 6 feet tall.]
During the inspection, John's team logged a discrepancy for this air terminal. Why? - ANSWER--
The air terminal is not attached to a conductor.
How many down conductors are required for a building with a perimeter length of 325 feet? -
ANSWER--4
While conducting an LPS inspection, you see mast down conductors routed as shown in the
image below. Do you write it up as a discrepancy? Why or why not?
- ANSWER--Yes, because mast down conductors should be 180 degrees apart.
A steel beam, connected to the main LPS at its upper and lower extremities, is used as a down
conductor. At what intervals should it be connected to the grounding system? - ANSWER--60
feet or less
Which statement about grounding systems is true? - ANSWER--The resistance should be 25
ohms or less.
Which of the following statements regarding bonding are true? Select all that apply. - ANSWER-
-Bonding reduces the threat of sideflash by providing a low impedance path to ground.
Bonding is a way of connecting LPS conductors to grounded metal objects.
When should a grounded metal object be considered for bonding? - ANSWER-- When it's within
6 feet of a conductor
Which bonding method is the most permanent and secure? - ANSWER-- Exothermic weld
, Which factors are used to calculate bonding distance?Select all that apply. - ANSWER--Height of
proposed bond
Flashover medium
Number of down conductors
While conducting the inspection, John's team noticed a new metal light pole installed 3 feet
from the down conductor at the corner of this building. They logged a discrepancy. Why? -
ANSWER--Because grounded metal objects within 6 feet of LPS conductors should be bonded to
it
Which types of information does an LPS record provide? Select all that apply. - ANSWER--Test
locations
Test item descriptions or listing
Type of test
Responsibilities for conducting and administering the test plan
Which section of DA PAM 385-64 provides LPS visual inspection guidance? - ANSWER--Appendix
D
How often is a visual inspection required on an LPS? - ANSWER--Every 12 months While
conducting the LPS inspection, the team saw these surveillance cameras.
Does this building comply with LPS standards? - ANSWER--No, because the surveillance cameras
are outside the zone of protection.
How long must LPS test results be kept on file? - ANSWER--6 inspection cycles
