Section 1: Explosives Safety Fundamentals
Q1: The primary purpose of explosives safety is to:
A. Maximize explosive power
B. Protect personnel and property from explosive hazards [CORRECT]
C. Increase ammunition production
D. Simplify storage procedures
Correct Answer: B
Rationale: The primary purpose of explosives safety, as outlined in AR 385-64, is to protect
personnel and property from the hazardous effects of ammunition and explosives (AE). Options
A, C, and D are not the primary safety objectives.
Q2: Which Army Regulation serves as the primary reference for ammunition and explosives
safety standards?
A. AR 190-11
B. AR 385-64 [CORRECT]
C. AR 700-48
D. FM 4-30.13
Correct Answer: B
Rationale: AR 385-64 (Ammunition and Explosives Safety Standards) is the primary regulation
governing explosives safety. AR 190-11 governs physical security. AR 700-48 covers recovery
and disposal.

Q3: What is the concept of "minimum practical risk" in explosives safety?
A. Avoiding all risks regardless of the mission impact.
B. Accepting risk only when the benefits outweigh the potential costs, consistent with mission
requirements. [CORRECT]
C. Delegating all risk decisions to the lowest possible level.
D. Ignoring minor safety violations to maintain operational tempo.
Correct Answer: B
Rationale: Minimum practical risk involves making decisions that balance the mission
requirements with the need to protect personnel and property. It does not mean avoiding all risk
or ignoring regulations.
Q4: The explosive "hazard zone" is defined as the area where:
A. Only authorized personnel are allowed.
B. The potential exists for injury to personnel or damage to property from an explosion.
[CORRECT]
C. Storage magazines are located.
D. Explosives are actively being manufactured.
Correct Answer: B
Rationale: The hazard zone is the area exposed to the potential hazardous effects (blast,
fragments, debris) resulting from an explosion or fire. It is not limited to storage areas.
Q5: Which of the following is NOT a primary hazard category associated with explosives?
A. Blast pressure
B. Fragmentation
C. Thermal radiation (heat)
D. Electronic interference [CORRECT]
,3
Correct Answer: D
Rationale: The primary hazardous effects of explosives are blast pressure (shock wave),
fragmentation/debris, and thermal radiation (heat). Electronic interference is a secondary or
compatibility concern, not a primary explosive effect.
Q6: The term "explosive safety site plan" (ESSP) refers to:
A. A plan to respond to explosive accidents.
B. A drawing and data package that defines the explosives limits and safety requirements for a
specific location. [CORRECT]
C. A training schedule for explosive handlers.
D. A security plan for storage magazines.
Correct Answer: B
Rationale: The ESSP is a comprehensive document that outlines the explosives limits, quantity
distances, and specific safety measures for a facility or site. It is required for all locations storing
or handling AE.
Q7: Who is ultimately responsible for explosives safety at an Army installation?
A. The Ammunition Officer
B. The Installation Commander [CORRECT]
C. The Safety Manager
D. The Unit Armorer
Correct Answer: B
Rationale: The Installation Commander has overall responsibility for the safety of the
installation, including compliance with explosives safety standards. The Safety Manager acts as
an advisor.

Q8: "Quantity Distance" (QD) is defined as:
A. The distance between two storage magazines.
B. The minimum distance required between an explosives location and other sites based on the
quantity of explosives. [CORRECT]
C. The maximum amount of explosives allowed in one location.
D. The distance a worker must travel to reach a magazine.
Correct Answer: B
Rationale: Quantity Distance (QD) is the minimum acceptable distance between an explosives
potential explosion site (PES) and an exposed site (ES), determined by the net explosive weight
(NEW) and the type of exposure.
Q9: What is the requirement for personal electronic devices (cell phones, pagers) in an explosive
storage area?
A. They are allowed if kept on silent mode.
B. They are generally prohibited unless specifically evaluated and approved for use.
[CORRECT]
C. They are allowed only inside vehicles.
D. They are allowed if they do not have a camera.
Correct Answer: B
Rationale: Electronic devices can generate radio frequency (RF) energy or static electricity,
which may act as an ignition source for electro-explosive devices (EEDs). Their use requires
strict evaluation and approval.
Q10: "Net Explosive Weight" (NEW) is best described as:
A. The total weight of the ammunition item.
B. The weight of the explosive material only, excluding packaging and hardware. [CORRECT]
C. The weight of the packaging and the explosive combined.
