Answers with Detailed Rationales |
Complete Exam Prep & Study Guide
1. Before demolition begins on a commercial structure, which condition
should be verified first from a regulatory and safety standpoint?
A. The replacement building's foundation design
B. The owner's preferred demolition sequence
C. Required permits, utility disconnects, hazardous-material surveys, and site-
specific safety planning
D. The contractor's equipment fuel capacity
Answer: Required permits, utility disconnects, hazardous-material surveys, and
site-specific safety planning
,Rationale: A demolition project must be properly authorized and evaluated
before physical work starts. Utility isolation, hazardous-material identification,
and safety planning are critical prerequisites.
2. What is the primary purpose of a pre-demolition structural survey?
A. Determine the final landscaping design
B. Calculate the contractor's profit margin
C. Identify structural conditions that could affect demolition stability and
worker safety
D. Determine the resale value of salvage materials
Answer: Identify structural conditions that could affect demolition stability and
worker safety
Rationale: The survey helps identify weakened members, unusual construction,
adjacent structures, and other hazards that influence the demolition sequence.
3. When demolishing a structure adjacent to an occupied building, which
consideration is most critical?
A. Maximizing production speed
B. Maintaining stability and protecting the adjacent structure throughout
demolition
C. Removing all interior finishes simultaneously
D. Using the largest excavator available
Answer: Maintaining stability and protecting the adjacent structure throughout
demolition
Rationale: Adjacent structures may be affected by vibration, undermining,
falling debris, or loss of lateral support. Demolition must be sequenced to
prevent these conditions.
4. What is the safest approach when an electrical service is believed to be
disconnected but the contractor cannot verify de-energization?
,A. Begin interior demolition using insulated tools
B. Assume the utility company disconnected it
C. Treat the conductors as energized until proper verification is completed
D. Remove the service entrance immediately
Answer: Treat the conductors as energized until proper verification is completed
Rationale: Unverified electrical systems must be treated as energized. Proper
lockout/tagout and verification procedures are essential before work proceeds.
5. Which demolition method generally provides the greatest control when
removing portions of a building next to a sensitive occupied facility?
A. Uncontrolled collapse
B. High-reach impact demolition without barriers
C. Controlled, sequential dismantling
D. Burning structural members
Answer: Controlled, sequential dismantling
Rationale: Sequential dismantling allows the contractor to control falling debris,
vibration, dust, and structural stability more effectively than uncontrolled
methods.
6. What is the principal reason for maintaining exclusion zones during
mechanical demolition?
A. To improve equipment fuel economy
B. To keep personnel outside areas exposed to falling debris, equipment
movement, and structural collapse
C. To provide additional parking
D. To reduce demolition permit fees
Answer: To keep personnel outside areas exposed to falling debris, equipment
movement, and structural collapse
Rationale: Mechanical demolition creates unpredictable fall and swing zones.
Exclusion areas reduce struck-by and caught-between hazards.
, 7. Which condition most strongly indicates that a wall should not be removed
without additional engineering evaluation?
A. The wall has painted drywall
B. The wall contains windows
C. The wall appears to provide lateral or vertical support to remaining
construction
D. The wall has electrical receptacles
Answer: The wall appears to provide lateral or vertical support to remaining
construction
Rationale: Removing a load-bearing or bracing element without a proper
sequence can cause partial or progressive collapse.
8. During demolition, why should debris accumulation on floors be
controlled?
A. It makes the building look untidy
B. Excessive debris can overload floors and create additional fall and access
hazards
C. It prevents recycling
D. It increases permit requirements
Answer: Excessive debris can overload floors and create additional fall and
access hazards
Rationale: Existing floors may not be designed to support concentrated
demolition debris. Debris also obstructs travel paths and increases fall hazards.
9. Which practice best controls dust during concrete demolition?
A. Increase demolition speed
B. Close all water valves
C. Use appropriate wet methods or engineering controls while maintaining
electrical safety
D. Remove respiratory protection
