1. In controlled demolition, the term “cutting charge” refers to:
A. A charge used to break concrete by expansion
B. An explosive charge placed to sever structural members
C. A device for transporting explosives on site
D. A charge used for sound suppresion
The term “cutting charge” specifically denotes an explosive charge
placed strategically to sever structural members during a demolition
sequence.
2. The primary purpose of a pre-demolition survey is to:
A. Train workers on demolition equipment
B. Identify hazards and structural conditions before demolition
C. Estimate project cost
D. Schedule waste disposal
A pre-demolition survey is conducted to identify hazards, utilities,
and structural conditions to ensure safety and planning accuracy.
3. When planning a controlled demolition, the most critical factor in
determining the charge placement is:
A. The color of building materials
B. Wind speed on the day of detonation
C. The load path and structural design of the building
D. The presence of interior furnishings
Understanding load path and structural design is essential to placing
charges where they will effectively weaken supports.
,4. NFPA standards relevant to demolition operations include:
A. NFPA 70E only
B. NFPA 1600 only
C. NFPA 495 and NFPA 499
D. NFPA 33 only
NFPA 495 (Explosive Materials Code) and NFPA 499 (Classifi cation of
Combustible Dusts) are directly applicable to demolition involving
explosives.
5. Before entering a demolition site, a controlled demolition supervisor
must ensure:
A. That demolition crews have lunch scheduled
B. Noise ordinances are ignored
C. Utilities are identified and disconnected
D. That explosives are stored inside the structure
Verifying utility identification and disconnection prevents unintended
ignitions and hazards during demolition.
6. A blast exclusion zone is defined as:
A. Area where only demolition supervisors can stand
B. A zone for storing debris
C. A restricted area to protect personnel and property during
detonation
D. A zone where debris can be thrown
An exclusion zone is established to ensure safety for personnel and
property by restricting access during blasts.
7. The term “toe charge” in demolition refers to:
A. A charge attached to workers’ boots
B. A charge used for perimeter blasting
C. A charge placed at the base of a column or wall to initiate collapse
D. A charge used for interior finishing
A toe charge is placed low on a structural member to help induce an
inward bend and collapse.
8. The minimum safe distance for observers during an explosive
demolition should be based on:
A. Local opinion
B. Weather only
, C. Calculated blast effects and regulatory standards
D. Time of day
Safe distances are determined by evaluating blast effects like
fragmentation and shock and following regulations.
9. A misfire in demolition operations means:
A. All charges detonated successfully
B. One or more charges failed to detonate as planned
C. Charge exploded prematurely
D. Debris failed to reach ground
A misfire indicates failure of one or more charges to detonate when
intended.
10. Which regulatory body oversees licensing for controlled
demolition supervisors in South Carolina?
A. OSHA only
B. South Carolina Department of Labor, Licensing and Regulation
C. EPA only
D. FAA
State licensing is typically managed by the South Carolina
Department of Labor, Licensing and Regulation.
11. A key component of a blast plan is:
A. Weather reports only
B. Crew meal schedules
C. Charge sequence and timing
D. Paint colors of equipment
A blast plan outlines charge sequencing and timing to ensure
controlled structural failure.
12. Prior to blasting, notification to adjacent property owners is
required to:
A. Increase noise exposure
B. Avoid liability insurance
C. Inform them of potential impacts and safety measures
D. Reduce paperwork
Notification ensures that adjacent owners are aware of and prepared
for demolition activities.
