AMMO 28 ARMY ELECTRICAL EXPLOSIVES
SAFETY EXAM 2026-2027 QUESTIONS AND
CORRECT ANSWERS GRADED A+
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?
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.
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?
Appendix D
,How often is a visual inspection required on an LPS?
Every 12 months
While conducting the LPS inspection, the team saw these surveillance cameras.
Does this building comply with LPS standards?
No, because the surveillance cameras are outside the zone of protection.
How long must LPS test results be kept on file?
6 inspection cycles
How often is a conductive floor electrical test required in an ESD-sensitive
operating facility?
Every 6 months
For best accuracy, how many individual resistance tests are recommended for a
conductive floor?
Refer to DA PAM 385-64, Section C-3 as required.
Ten test: Five electrode-to-electrode tests and five electrode-to-ground tests
,This conductive floor was tested at five locations. The average resistance of the
electrode-to-electrode test was 55,871 ohms. Does this test pass? Refer to DA
PAM 385-64, Section C-3.
Yes, because an average resistance of 55,871 ohms is within standards
How often is a 3-point fall-of-potential earth resistance test required on an LPS?
Every 24 months
When conducting a 3-point fall-of-potential earth resistance test on an integral
LPS, how far from the ground rod should you place the C2 and P2 test probes?
Refer to DA PAM 385-64, Table B-1 as required.
Select one response for the C2 probe distance and one response for the P2 probe
distance.
C2 probe at 131 feet
P2 probe at 82 feet
What is the maximum allowable resistance reading for a 3-point fall-of-potential
earth resistance test?
25 ohms or less
How often is a bonding resistance test required on an LPS?
, Every 24 months
What is the maximum allowable reading for a bonding resistance test on an LPS
conductor?
1 ohm or less
When conducting a bonding resistance test on an integral LPS with 10 air terminals
and two down conductors, how many individual resistance tests are required, at a
minimum?
20
While conducting a bonding resistance test on the integral LPS below, you placed
test leads on ground rod S and air terminal N. Which three bonds listed below are
NOT being tested?
B
H
P
What information should be in a destructive weather plan? Select all that apply.
Which operations to shut down
Who is responsible for shutting down each operation
