Questions and Answers Graded A+ comprehensive
110+ question exam on the Application of US
Army ESQD Principles, complete with answers and
detailed rationales!!!
Section 1: Regulatory Framework and Foundational Concepts.
1. Which document contains the minimum required ESQD criteria for the US Army?
a) DESR 6055.09
b) DA PAM 385-64
c) OSHA 1910.109
d) NFPA 1127
Correct Answer: b) DA PAM 385-64
*Rationale: DA PAM 385-64 (Ammunition and Explosives Safety Standards) is the specific
Army regulation that implements the DoD’s ESQD requirements outlined in DESR 6055.09.
While DESR 6055.09 applies to all branches, DA PAM 385-64 is the governing publication for
the Army.*
2. The "Cardinal Rule" of explosives safety is designed primarily to protect:
a) Ammunition and explosives (AE) from theft
b) The continuity of military operations
c) People and property
d) The environment from contamination
,Correct Answer: c) People and property
Rationale: The Cardinal Rule states: "Expose the minimum number of people for the
minimum time to the minimum amount of explosives." This risk management principle
prioritizes human life and critical infrastructure over the protection of the explosives
themselves.
3. After the Lake Denmark Naval Ammunition Depot mishap in 1926, what did the State of
New Jersey create that was later adopted by the War Department?
a) The first fire suppression sprinkler system
b) Standardized ESQD tables
c) The concept of Net Explosive Weight (NEW)
d) Barricade construction standards
Correct Answer: b) Standardized ESQD tables
Rationale: The catastrophic explosion at Lake Denmark (which shared a border with a
Picatinny Arsenal facility) resulted in widespread off-site damage. The subsequent legal and
safety reviews led New Jersey to establish quantity-distance regulations, which served as the
model for the War Department’s first standardized QD criteria.
4. The purpose of ESQD requirements is to:
a) Eliminate all explosive hazards
b) Minimize potential damage
c) Maximize storage efficiency
d) Reduce transportation costs
Correct Answer: b) Minimize potential damage
Rationale: ESQD principles do not prevent explosions; they mitigate the effects. By controlling
the quantity of explosives (Q) and the distance (D) from exposed sites (people, buildings,
roads), the goal is to minimize the risk of propagation, injury, and structural damage.
5. Quantity Distance (QD) provides protection by:
a) Increasing the weight of explosives stored
b) Limiting the amount of explosives and varying the distance
c) Standardizing the type of explosives used
d) Requiring all explosives to be stored underground
,Correct Answer: b) Limiting the amount of explosives and varying the distance
Rationale: QD is a risk management formula. For a given location (PES), you can either limit
the Net Explosive Weight (Q) to allow a shorter distance (D), or increase the distance to
accommodate a larger quantity.
6. Detonation is a characteristic of:
a) Low explosives
b) High explosives
c) Propellants only
d) Pyrotechnics only
Correct Answer: b) High explosives
*Rationale: High explosives (e.g., TNT, C-4) undergo detonation, a supersonic chemical
reaction producing a shock wave. Low explosives (e.g., black powder) undergo deflagration
(rapid burning).*
7. Which Hazard Division (HD) consists of explosives that present a mass explosion hazard?
a) HD 1.2
b) HD 1.3
c) HD 1.4
d) HD 1.1
Correct Answer: d) HD 1.1
Rationale: By definition, Hazard Division 1.1 includes substances and articles that have a
mass explosion hazard. A mass explosion affects virtually the entire load instantaneously.
8. HD 1.2 consists of explosives that present a:
a) Mass fire hazard
b) Mass explosion hazard
c) Non-mass explosion, fragment-producing hazard
d) No significant hazard
Correct Answer: c) Non-mass explosion, fragment-producing hazard
Rationale: HD 1.2 materials are characterized by a projection hazard (fragments) but not a
mass explosion hazard. The explosion is localized but sends dangerous fragments outward.
, 9. HD 1.3 consists of explosives that present a:
a) Mass fire, minor blast, or minor fragment hazard
b) Mass explosion hazard
c) Hypergolic reaction hazard
d) Toxic chemical release hazard
Correct Answer: a) Mass fire, minor blast, or minor fragment hazard
*Rationale: HD 1.3 includes propellants and pyrotechnics. The primary risk is rapid
combustion leading to a mass fire, though minor blast/fragmentation may occur from
packaging or individual articles.*
10. HD 1.4 consists of explosives that present a:
a) Mass explosion hazard
b) Significant fragmentation hazard
c) Moderate fire, no significant blast or fragment hazard
d) Toxic vapor hazard
Correct Answer: c) Moderate fire, no significant blast or fragment hazard
Rationale: HD 1.4 is the lowest risk category for explosives. While they may catch fire, they
are packaged or designed to limit the effects, preventing fragments from leaving the
package or significant blast overpressure.
11. Which document contains the minimum required ESQD criteria for ALL branches of
service?
a) DA PAM 385-64
b) UFC 3-340-01
c) DESR 6055.09
d) AR 190-11
Correct Answer: c) DESR 6055.09
Rationale: The Department of Defense Explosives Safety Regulation (DESR 6055.09) is the
overarching directive for all DoD components (Army, Navy, Air Force, Marines).
12. A location containing Ammunition and Explosives (AE) that could create a blast if an
explosion occurs is a/an:
