US ARMY EXPLOSIVE SAFETY
FAMILIARIZATION COMPREHENSIVE
EXAMINATION 2026/2027 | VERIFIED
QUESTIONS
DOMAIN 1: EXPLOSIVES SAFETY FUNDAMENTALS
1. What is the primary purpose of an Explosives Safety Management Program
(ESMP)?
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
Correct Answer: B
Rationale: The ESMP aims to minimize risk from explosives by establishing
safety standards for operations, storage, transportation, and handling, protecting
personnel and assets. It is not limited to inventory tracking, deployment, or EOD
training.
2. What type of detonation occurs when a storage facility with high explosives
detonates and its shock wave hits a nearby facility causing another explosion?
A) Deflagrate detonation
B) Sympathetic detonation
C) Primary detonation
,D) Secondary detonation
Correct Answer: B
Rationale: Sympathetic detonation occurs when the shock wave from one
explosion triggers a secondary explosion in a nearby facility or munition stack. This
is a critical concern in storage site planning and quantity-distance calculations.
3. Which of the following chemicals will react violently when it comes in contact
with water?
A) TNT, RDX, HMX
B) TH, HC, TPA
C) C-4, Composition B, PBX
D) Nitroglycerin, PETN, Tetryl
Correct Answer: B
Rationale: TH (Thermite), HC (Hexachloroethane), and TPA (Triphenylamine)
are chemicals that react violently with water. This knowledge is essential for
emergency response and storage planning.
4. Select the division of Hazard Class 1 that is the most dangerous.
A) 1.2
B) 1.3
C) 1.4
D) 1.1
Correct Answer: D
, Rationale: Hazard Division 1.1 presents a mass explosion hazard, making it the
most dangerous division within Class 1. A mass explosion affects almost the entire
load instantaneously.
5. The ultimate purpose of quantity distance is?
A) To maximize storage capacity
B) Protecting personnel, equipment, and buildings from accidental explosions
C) To reduce transportation costs
D) To increase operational efficiency
Correct Answer: B
Rationale: Quantity distance (QD) is designed to protect personnel,
equipment, and buildings from the effects of accidental explosions by establishing
minimum separation distances based on net explosive weight and hazard division.
6. If a pallet holds 12 HE rounds and each round contains 17.5 lb of NEW, what
would be the NEW of the pallet?
A) 140 lb
B) 175 lb
C) 210 lb
D) 240 lb
Correct Answer: C
Rationale: 12 rounds × 17.5 lb = 210 lb NEW. Net Explosive Weight (NEW) is
the total weight of explosive content only, excluding packaging and containers.
7. Why are there divisions within Class 1?
, A) To indicate the weight of the explosive
B) Specific hazards posed
C) To indicate the color of the packaging
D) To indicate the age of the ammunition
Correct Answer: B
Rationale: Divisions within Class 1 are based on the specific hazards posed by
the explosive materials, such as mass explosion, fragmentation, or fire. This
classification system ensures proper handling and storage.
8. Cardinal Rule for safety is:
A) People, equipment, time
B) People, explosives, time
C) Equipment, explosives, time
D) People, equipment, explosives
Correct Answer: B
Rationale: The Cardinal Rule for safety is "people, explosives, time,"
emphasizing the priority of protecting personnel when working with explosives.
This principle guides all explosives safety decisions.
9. Who is responsible for the risk management process?
A) Only commanders
B) Only safety officers
C) Everyone
D) Only ammunition handlers
