adopted by the War Department?
A. Minimum explosive safety training standards
B. Standardized ESQD tables
C. The Army Explosives Safety Program (AR 385-10)
D. The first above-ground magazine design
Answer: B
Explanation: Following the catastrophic explosion at Lake Denmark, New Jersey developed
standardized ESQD tables, which were subsequently adopted by the War Department as the
foundation for explosive safety regulations
2. Which Department of Defense document contains the minimum required ESQD criteria for all
branches of service?
A. DA PAM 385-64
B. AR 385-10
C. DESR 6055.09, Edition 1
D. NAVSEA OP 5
Answer: C
Explanation: DESR 6055.09, Edition 1 (Department of Defense Explosives Safety Regulation)
establishes the baseline ESQD criteria applicable to all U.S. military branches.
,3. Which document contains the minimum required ESQD criteria specifically for the Army?
A. DESR 6055.09
B. AR 385-64
C. DA PAM 385-64
D. DoD 6055.09-STD
Answer: C
Explanation: DA PAM 385-64 (Ammunition and Explosives Safety Standards) provides the Army-
specific implementation of explosives safety requirements, including ESQD criteria.
4. The cardinal rule for explosives safety is designed to protect:
A. Ammunition and explosives only
B. Ammunition, explosives, and property
C. People and property
D. Property and public roadways
Answer: C
Explanation: The cardinal rule prioritizes protection of people and property by ensuring minimum
people, minimum time, and minimum explosives are used during operations.
5. What are the three components of the cardinal rule for explosives safety?
A. Maximum distance, maximum shielding, maximum warning time
B. Minimum people, minimum time, minimum explosives
C. Maximum people, maximum distance, maximum explosives
D. Minimum distance, minimum shielding, minimum explosives
Answer: B
,Explanation: The cardinal rule requires that operations involving ammunition and explosives use
the minimum number of people for the minimum time with the minimum quantity of explosives
necessary.
6. The primary purpose of ESQD requirements is to:
A. Maximize storage capacity at ammunition depots
B. Minimize potential damage from an accidental explosion
C. Reduce the cost of ammunition storage
D. Standardize ammunition packaging across all branches
Answer: B
Explanation: ESQD requirements are fundamentally designed to minimize the potential damage
to people, property, and the environment in the event of an accidental explosion
7. Quantity distance provides the greatest amount of protection between locations by:
A. Limiting the amount of explosives and varying the distance
B. Increasing the amount of explosives and decreasing the distance
C. Standardizing both the amount of explosives and the distance
D. Using only earth-covered magazines
Answer: A
Explanation: The QD principle balances two variables: limiting the quantity of explosives stored
and increasing the separation distance to achieve the desired level of protection.
8. The Lake Denmark mishap occurred in which year and involved what type of facility?
A. 1916, Naval Ammunition Depot
B. 1926, Naval Ammunition Depot
C. 1936, Army Ammunition Plant
D. 1946, Air Force Munitions Storage Area
, Answer: B
Explanation: The Lake Denmark mishap occurred in 1926 at a Naval Ammunition Depot in New
Jersey, leading to significant reforms in explosives safety regulations.
9. Which Army regulation establishes the overall Army Safety Program and references DA PAM
385-64 for explosives safety?
A. AR 385-10
B. AR 190-11
C. AR 700-141
D. AR 710-2
Answer: A
Explanation: AR 385-10 (The Army Safety Program) is the overarching regulation that establishes
safety policies and references DA PAM 385-64 for specific ammunition and explosives safety
standards.
10. The Department of Defense Explosives Safety Board (DDESB) is responsible for:
A. Manufacturing all military explosives
B. Approving explosives safety site plans and waivers
C. Conducting all ammunition inspections
D. Training all explosives safety personnel
Answer: B
Explanation: DDESB provides final approval for explosives safety site plans (ESSPs) and reviews
waivers and exemptions from ESQD criteria.
11. DA PAM 385-64 implements which Department of Defense standard?
A. DoD 4145.26-M
