The US Army Explosive Safety Familiarization (AMMO-63-DL) course is a mandatory, competency-based training
requirement for all personnel who handle, store, transport, or supervise ammunition and explosives (A&E)
within the Department of Defense. Administered by the Defense Ammunition Center (DAC) and governed by
DESR 6055.09, AR 385-10, and DA PAM 385-64, this course ensures that every service member understands the
catastrophic consequences of improper A&E handling and the regulatory framework designed to prevent
mishaps. The exam is critical because a single failure in explosives safety can result in mass casualties,
destruction of critical assets, and mission failure. The assessment consists of multiple-choice and scenario-
based questions covering hazard classification, quantity-distance (QD) principles, storage compatibility, net
explosive weight (NEW) calculations, transportation safety, electromagnetic radiation hazards, and emergency
response procedures. This question bank has been meticulously crafted to simulate the advanced, application-
level difficulty of the actual AMMO-63-DL exam. By working through these 200 scenario-driven questions, you
will develop the regulatory precision and safety critical thinking needed to pass on your first attempt.
CORE DOMAINS TESTED
1. Explosives Safety Fundamentals & the Cardinal Principle – Minimum exposure of personnel through
separation, quantity-distance, and proper siting; risk management responsibilities; and the ESMP
framework.
2. Hazard Classification & Divisions – HD 1.1 through 1.6, mass explosion vs. non-mass explosion
hazards, fragmentation, fire hazards, and compatibility groups (A through S).
3. Quantity-Distance (QD) Principles & NEW Calculations – Intermagazine Distance (IMD), Intraline
Distance (ILD), Inhabited Building Distance (IBD), Public Traffic Route Distance (PTRD), and Net
Explosive Weight (NEW) computation from DODIC data.
4. Storage Safety & Magazine Operations – Earth-covered magazines (ECMs), above-ground magazines
(AGMs), housekeeping rules, fire symbols, chemical symbols, and compatibility mixing restrictions.
5. Transportation Safety & Hazardous Materials – DODIC/placard requirements, vehicle inspections,
blocking and bracing, off-post vs. on-post requirements, and driver qualifications.
6. Ammunition Identification, Stability & Malfunctions – Inert vs. live items, stability factors (time,
temperature, moisture), ammunition residue, and malfunction reporting procedures.
7. Electromagnetic Radiation (EMR) & Electro-Explosive Devices (EEDs) – Hazards from radio frequency,
static electricity, lightning protection systems (LPS), and clothing requirements to minimize static.
,2
8. Personal Protective Equipment (PPE) & Safety Protocols – PPE for chemical fillers, heat sealing safety,
material handling equipment (MHE) precautions, and housekeeping guidelines.
9. Emergency Response, Accidents & Incidents – Accident notification, investigation, fire protection,
near-miss reporting, and emergency action channels.
10. Regulatory Framework & References – DESR 6055.09, AR 385-10, DA PAM 385-64, the Yellow Book
(TM 38-410), and SOP requirements.
QUESTIONS 1-200
Q1: An ammunition supply point commander is reviewing explosives safety
principles for a new facility storing HD 1.1 munitions. Which of the following
represents the Cardinal Principle of explosives safety that must guide all A&E
operations?
A) Maximum quantity storage with minimal separation distances to optimize
facility utilization
B) Minimum exposure of personnel to explosives through separation,
quantity-distance, and proper siting
C) Storage of maximum quantities to reduce handling frequency and minimize
accident probability
D) Co-location of all compatibility groups to simplify inventory management
Rationale: The correct answer is B because the Cardinal Principle, established in
DESR 6055.09, mandates minimum exposure of personnel through separation,
QD, and proper siting. Option A violates QD principles. Option C contradicts the
minimum exposure concept. Option D violates compatibility group segregation
requirements.
Q2: During a safety inspection, a safety officer observes that two earth-covered
magazines (ECMs) containing HD 1.1 explosives are positioned such that the
front of one faces the side of another. What is the minimum required
Intramagazine Distance (IMD) between these facilities?
A) 0 feet (zero)
B) 100 feet
C) 200 feet
D) Based on the NEWQD calculation
Rationale: The correct answer is A because properly constructed ECMs with
headwalls provide sufficient protection against propagation, making the IMD
,3
zero when the side or rear of one faces another. Option B applies to certain HD
1.2 scenarios. Option C is not standard IMD for ECM-to-ECM. Option D applies
to bare explosives in the open.
Q3: A facility stores 500 lbs of HD 1.1 explosives in an above-ground structure
(AGS). What is the minimum Inhabited Building Distance (IBD) required per
DESR 6055.09 QD tables?
A) 400 feet
B) 660 feet
C) 750 feet
D) 1,250 feet
Rationale: The correct answer is B because DESR 6055.09 Volume 3, Table
V3.E3.T1 specifies 660 feet IBD for 500 lbs NEWQD of HD 1.1 in an AGS. Options
A, C, and D do not correspond to the correct QD table values for this NEW.
Q4: Which Hazard Division is characterized by a mass explosion hazard that
affects almost the entire load instantaneously?
A) HD 1.2
B) HD 1.3
C) HD 1.4
D) HD 1.1
Rationale: The correct answer is D because HD 1.1 involves a mass explosion
hazard. Option A is a non-mass explosion, fragment-producing hazard. Option B
is a mass fire hazard with minor blast. Option C presents a minor explosion
hazard.
Q5: A pallet holds 12 high-explosive rounds, each containing 17.5 lb of NEW.
What is the total NEW of the pallet?
A) 140 lb
B) 175 lb
C) 210 lb
D) 240 lb
Rationale: The correct answer is C because 12 rounds × 17.5 lb = 210 lb NEW.
Options A, B, and D result from incorrect multiplication or addition.
Q6: What is the primary purpose of an Explosives Safety Management Program
(ESMP)?
, 4
A) To track inventory of ammunition only
B) To protect personnel, property, and the environment from the effects of
mishaps involving ammunition and explosives
C) To ensure rapid deployment of munitions
D) To train soldiers in explosive ordnance disposal
Rationale: The correct answer is B because the ESMP establishes safety
standards for operations, storage, transportation, and handling. Option A is too
narrow. Option C is a mission objective, not a safety program. Option D is a
separate training function.
Q7: When two different Compatibility Groups are stored in the same magazine,
what rule applies?
A) The supervisor's discretion
B) The most restrictive compatibility rules, using approved mixed storage
tables
C) Any arrangement as long as the total weight is under 500 lbs
D) Separate buildings only
Rationale: The correct answer is B because mixing compatibility groups is
allowed only when authorized in approved mixed-storage tables. Option A is
incorrect because safety is not discretionary. Option C ignores compatibility
hazards. Option D is overly restrictive and not required when compatible
storage is authorized.
Q8: A storage facility with high explosives detonates, and its shock wave hits a
nearby facility causing another explosion. What type of detonation is this?
A) Deflagrate detonation
B) Sympathetic detonation
C) Primary detonation
D) Secondary detonation
Rationale: The correct answer is B because sympathetic detonation occurs
when one explosion triggers another. Option A describes subsonic combustion.
Option C is not a recognized detonation type. Option D is a general term but not
the specific phenomenon described.
Q9: Which of the following chemicals will react violently when it comes in
contact with water?
A) TNT, RDX, HMX
