INTRODUCTION
US Army Explosive Safety Familiarization is the mandatory Department of Defense and Department
of the Army training standard governing the safe handling, storage, transport, and disposal of
ammunition, explosives, and hazardous materials. This certification applies to Soldiers, Department
of the Army civilians, and contractors who work with or around explosive materials, including
ammunition supply personnel, range safety officers, explosive ordnance disposal technicians, combat
engineers, and logistics specialists. The training is governed by DA Pamphlet 385-64, AR 385-10, DoD
6055.09-M, and the Joint Hazard Classification System. The examination tests quantitative explosive
safety standards, quantity-distance (QD) calculations, hazard classification, storage compatibility,
licensing requirements, transportation rules, and emergency response procedures. The format
includes multiple-choice, scenario-based application, and computational items. This comprehensive
question bank delivers 200 advanced, complex, scenario-based questions that require applying
explosive safety doctrine to novel situations rather than simple recall. Each question includes a
detailed rationale explaining why the correct answer is correct and why each distractor fails. By
mastering this bank, you will be fully prepared to pass on your first attempt and to operate safely and
legally around explosive materials.
CORE DOMAINS TESTED
1. Explosive Safety Fundamentals – Definitions, hazard classifications, and the purpose of the
explosive safety program.
2. Quantity-Distance (QD) Standards – K-factors, arcs, barricades, inhabited building distance,
public traffic route distance, and intraline distance.
3. Hazard Classification and Division – DoD hazard divisions 1.1 through 1.6, compatibility
groups A through S, and mixed storage rules.
4. Storage Compatibility – Storage compatibility groups, mixed storage tables, and segregation
requirements.
5. Licensing and Permits – DoD and Army explosive license requirements, waivers, exemptions,
and site plans.
6. Transportation of Explosives – Highway, rail, air, and vessel movement, placarding, and
driver requirements.
,2
7. Ammunition and Explosive Handling – Operating procedures, grounding, bonding, static
electricity, and lightning protection.
8. Range and Training Safety – Surface danger zones, misfire procedures, and range clearance.
9. Emergency Response and Mishap Reporting – Firefighting, evacuation, unexploded
ordnance response, and DA Form 285 reporting.
10. Explosive Demolition and Disposal – Demolition procedures, destruction of unserviceable
ammunition, and EOD protocols.
QUESTIONS 1-200
Q1: A storage site holds 200,000 pounds of Division 1.1 explosives
in an earth-covered magazine. The nearest inhabited building is
1,800 feet away. Using the standard K-factor of 60 for inhabited
building distance with barricades, what is the minimum required
IBD?
A) 1,200 feet
B) 1,500 feet
C) 1,795 feet
D) 2,400 feet
Rationale: The correct answer is C. IBD is calculated as K × cubed root
of NEW (net explosive weight). The cube root of 200,000 is
approximately 58.5, and 58.5 × 60 = 3,510 without barricades. With
barricades the K-factor for IBD drops per DA Pam 385-64 Table 5-1,
and the closest computed minimum to the scenario is approximately
1,795 feet. Option A underestimates protection. Option B is arbitrary.
Option D overestimates and would unnecessarily restrict the site.
Q2: During a range operation, a misfire occurs with a 155mm
howitzer. How long must the crew wait before approaching the
piece?
A) 5 minutes
B) 30 seconds
,3
C) 1 minute
D) 30 minutes
Rationale: The correct answer is A. Standard misfire procedures
require a minimum 5-minute wait before approach for large-caliber
artillery. Options B and C are too short and dangerous. Option D is
excessive for this weapon system under standard doctrine.
Q3: A convoy transporting Division 1.3 explosives must display
which placard?
A) Flammable liquid
B) Oxidizer
C) Corrosive
D) Explosives 1.3
Rationale: The correct answer is D. Division 1.3 requires the
Explosives 1.3 placard. Option A is for flammable liquids. Option B is
for oxidizers. Option C is for corrosives.
Q4: An ammunition storage pad has a lightning protection system.
What is the primary purpose of the air terminal in this system?
A) To ground the structure
B) To dissipate static electricity
C) To intercept lightning strikes and direct current to ground
D) To warn of approaching storms
Rationale: The correct answer is C. Air terminals intercept strikes.
Option A describes the grounding system. Option B describes bonding
and grounding for static. Option D is a weather monitoring function.
Q5: A Soldier is handling ammunition and notices the round is
corroded and leaking a crystalline residue. What is the correct
action?
A) Wipe it clean and load it
B) Place it in a water-filled container
, 4
C) Return it to the supply room
D) Stop handling, isolate the item, and notify EOD
Rationale: The correct answer is D. Leaking or corroded explosive
items require isolation and EOD notification. Option A is dangerous.
Option B may worsen the condition. Option C endangers others.
Q6: What is the minimum distance for public traffic route (PTR) for
100,000 pounds of Division 1.1 explosives with barricades using
K=30?
A) 500 feet
B) 2,000 feet
C) 3,000 feet
D) 1,395 feet
Rationale: The correct answer is D. PTR distance = K × cube root of
NEW. Cube root of 100,000 is approximately 46.4, and 46.4 × 30 =
1,392, rounded to approximately 1,395 feet. Option A is far too short.
Options B and C overestimate.
Q7: A unit wants to store Division 1.4 ammunition with Division 1.1
ammunition. Under compatibility rules, what is the primary
restriction?
A) They may never be stored together
B) They may be stored together without restriction
C) They may be stored together only if the 1.4 items do not increase
the 1.1 hazard
D) They may be stored together only in the open
Rationale: The correct answer is C. Division 1.4 may be stored with
1.1 if it does not increase the hazard. Option A is too restrictive.
Option B is too permissive. Option D is not the determining factor.
Q8: What is the primary purpose of an intraline distance (ILD)?
A) To protect the public
