US ARMY EXPLOSIVE SAFETY
FAMILIARIZATION EXAM QUESTIONS
WITH 100% CORRECT ANSWERS
2026/2027
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 – The ESMP aims to minimize risk from explosives by
establishing safety standards for operations, storage, transportation, and handling,
protecting personnel and assets.
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
1
,Correct Answer: B – This is known as sympathetic detonation, where the shock
wave from one explosion triggers a secondary explosion in a nearby facility.
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 – TH (Thermite), HC (Hexachloroethane), and TPA
(Triphenylamine) are chemicals that react violently with water.
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 – Hazard Division 1.1 presents a mass explosion hazard,
making it the most dangerous division within Class 1.
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
2
,Correct Answer: B – Quantity distance (QD) is designed to protect personnel,
equipment, and buildings from the effects of accidental explosions by establishing
minimum separation distances.
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 – 12 rounds × 17.5 lb = 210 lb NEW.
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 – Divisions within Class 1 are based on the specific hazards
posed by the explosive materials, such as mass explosion, fragmentation, or fire.
8. Cardinal Rule for safety is:
A) People, equipment, time
B) People, explosives, time
C) Equipment, explosives, time
3
, D) People, equipment, explosives
Correct Answer: B – The Cardinal Rule for safety is "people, explosives, time,"
emphasizing the priority of protecting personnel when working with explosives.
9. Who is responsible for the risk management process?
A) Only commanders
B) Only safety officers
C) Everyone
D) Only ammunition handlers
Correct Answer: C – Risk management is everyone's responsibility; all personnel
involved in ammunition and explosives operations must participate in the process.
10. According to Army explosives safety regulations, which of the following is the
minimum distance personnel should be from a non-essential explosive operation?
A) 50 feet
B) 100 feet
C) Interceptor distance as specified by quantity-distance (QD) tables
D) 300 feet
Correct Answer: C – Quantity-distance (QD) tables define required separation
distances based on the net explosive weight (NEW) and the type of hazard. There
is no single fixed minimum; it depends on the situation.
11. A Compatibility Group is a letter designation assigned to ammunition and
explosives based on:
4
