1. Which of the following is the primary purpose of the MSHA
Explosive Materials Transportation Safety regulations?
A. To reduce transportation costs of explosives
B. To standardize explosive types across mines
C. To ensure the safe handling and transport of explosives to
prevent accidents
D. To increase production efficiency in mining operations
Rationale: The primary goal of MSHA transportation regulations is
safety. These rules are designed to prevent accidents and injuries by
ensuring explosives are handled, stored, and transported safely.
2. Before transporting explosives, the transporter must ensure:
A. The cargo truck is painted in reflective colors
B. Proper shipping papers, placards, and documentation are
complete and accurate
C. The vehicle driver has a mining license
D. The destination mine is at least 50 miles away
Rationale: Correct documentation, placards, and shipping papers are
legally required and critical for emergency response if an incident occurs
during transport.
, 3. Which of the following is NOT an approved method for
transporting explosives?
A. In an enclosed vehicle with a locked compartment
B. On a trailer with approved signage and placards
C. In the passenger compartment of a vehicle
D. In a magazine truck designed for explosive transport
Rationale: Explosives must never be transported in the passenger
compartment of a vehicle due to extreme risk to the driver and
passengers.
4. What is the maximum quantity of explosives that may generally be
transported in a single vehicle without special permits?
A. 500 pounds
B. 1,000 pounds
C. It depends on the type of explosive and local regulations
D. 10,000 pounds
Rationale: MSHA and DOT regulations vary by explosive type, hazard
class, and local requirements; there is no universal maximum.
5. Which placard must be displayed when transporting blasting
agents?
A. Flammable Gas
B. Explosive 1.5
C. Corrosive
D. Radioactive
Rationale: Blasting agents are classified under Division 1.5 explosives;
placards must clearly indicate this classification for emergency
responders.
, 6. How often must drivers transporting explosives inspect their
vehicles?
A. Only at the start of the trip
B. Before, during, and after the trip according to regulations
C. Once per week
D. Only if an accident occurs
Rationale: Frequent inspections ensure safety throughout the journey
and compliance with MSHA and DOT regulations.
7. Which type of fire extinguisher is typically required in vehicles
transporting explosives?
A. Water-based
B. Foam-based
C. Dry chemical or CO₂ rated for Class B and C fires
D. Wet chemical only
Rationale: Dry chemical and CO₂ extinguishers are effective for
flammable liquids and electrical fires, common hazards in transport
vehicles.
8. When transporting explosives, drivers must maintain a minimum
distance from:
A. Gas stations
B. Residential areas
C. Schools, hospitals, and populated areas whenever feasible
D. All highways
Rationale: Routes should avoid high-density areas to reduce the risk to
the public in case of an incident.
, 9. How should explosives be secured during transportation?
A. Loosely tied in the bed of a truck
B. Using appropriate restraints to prevent movement, damage,
or friction
C. Stacked in boxes without any restraint
D. Covered only with a tarp
Rationale: Proper restraint prevents shifting, impact, and friction, which
could trigger detonation.
10. What is the minimum age for a driver to transport explosives
commercially?
A. 16
B. 18
C. 21
D. 25
Rationale: Federal regulations require drivers transporting explosives to
be at least 21 years old to ensure adequate maturity and responsibility.
11. During transport, what is the correct procedure if a fire starts
near the explosives?
A. Drive through the fire as quickly as possible
B. Ignore it if flames are small
C. Stop at a safe distance, evacuate, and call emergency services
D. Use water from the vehicle tank to extinguish immediately
Rationale: The priority is human safety. Attempting to extinguish a fire
near explosives can be fatal.
12. Which federal agency regulates the transportation of
explosives on public highways?
