1. Which of the following is the primary hazard associated with
transporting explosives?
A. Electrical shock
B. Detonation or accidental explosion
C. Chemical burns
D. Radiation exposure
Rationale: Explosives are highly sensitive materials, and the primary
hazard during transport is unintended detonation, which can result in
severe injury or death.
2. What is the most critical factor when selecting a vehicle for
transporting explosives?
A. Fuel efficiency
B. Color of the vehicle
C. Vehicle stability and suitability for hazardous materials
D. Brand and model
Rationale: Vehicles used for transporting explosives must be stable,
capable of handling weight, and compliant with hazardous material
regulations to minimize the risk of accidents.
, 3. Which document must always accompany explosives during
transportation?
A. Driver’s license
B. Vehicle registration
C. Shipping papers or manifest detailing the explosives
D. Maintenance log
Rationale: Shipping papers provide critical information on the type,
quantity, and hazards of explosives, ensuring emergency responders can
react appropriately in an incident.
4. Explosives must be stored in vehicles during transport in a way
that:
A. Maximizes speed
B. Prevents movement, impact, and exposure to heat or sparks
C. Allows easy access by the driver
D. Reduces vehicle weight
Rationale: Proper storage prevents friction, impact, or environmental
factors from initiating detonation, ensuring safety.
5. Drivers transporting explosives should maintain a minimum
distance from:
A. Residential areas
B. Schools
C. Crowded public areas and populated zones
D. Gas stations
Rationale: Maintaining a safe distance from populated areas reduces
the risk of mass casualties in the event of an accidental detonation.
, 6. The use of electronic devices while transporting explosives is
generally:
A. Encouraged for navigation
B. Restricted or prohibited
C. Allowed if the vehicle is moving slowly
D. Required for communication
Rationale: Electronic devices can emit sparks or electromagnetic
interference that may accidentally detonate explosives, so their use is
restricted.
7. Explosives transportation vehicles must display:
A. Standard company logos
B. Personal identification numbers
C. Hazardous materials placards or signs
D. Insurance information
Rationale: Placards alert law enforcement, emergency responders, and
the public to the nature of the cargo, facilitating proper precautions.
8. What is the primary reason for driver training in explosive
transportation?
A. To improve fuel efficiency
B. To reduce the risk of accidents and ensure regulatory
compliance
C. To maintain vehicle appearance
D. To shorten delivery times
Rationale: Specialized training ensures that drivers understand
handling, storage, route planning, emergency procedures, and
regulatory compliance, reducing risks.
, 9. When transporting explosives, drivers must:
A. Take the shortest route regardless of conditions
B. Avoid congested routes and follow approved routes
C. Travel only at night
D. Stop frequently for rest
Rationale: Route planning minimizes exposure to traffic hazards,
populated areas, and road conditions that could increase the risk of
accidents.
10. Which of the following is considered an environmental
hazard for explosives transport?
A. Excessive rain
B. High temperature or friction
C. Air pollution
D. Road signage
Rationale: Heat, friction, and vibration can initiate detonation;
therefore, environmental conditions must be carefully monitored.
11. A driver notices a leaking container of explosives. What
should they do first?
A. Continue to the destination
B. Try to repair it themselves
C. Stop the vehicle and notify the appropriate authorities
D. Move it to the back of the vehicle
Rationale: Leaking explosives present immediate danger; stopping and
notifying authorities prevents escalation and ensures professional
handling.
