1. What is the most critical first action in developing a demolition project
plan for a mid-rise structure in an urban environment where adjacent
buildings remain occupied?
A. Begin removal of non-load-bearing partitions to reduce interior
weight
B. Conduct a comprehensive structural, environmental, and utility
assessment of the site and surrounding properties
C. Mobilize heavy machinery to reduce project duration and cost
overruns
D. Install debris chutes to prepare for material disposal during
demolition
Answer: B
A thorough assessment is essential to identify structural weaknesses,
, hazardous materials such as asbestos, and utility connections, as well
as risks to adjacent occupied buildings, ensuring safe planning before
any physical demolition begins.
2. Which OSHA standard most directly regulates safety requirements for
demolition operations in construction sites?
A. 29 CFR 1910 Subpart Z
B. 29 CFR 1917 Subpart C
C. 29 CFR 1926 Subpart T
D. 29 CFR 1915 Subpart D
Answer: C
OSHA 29 CFR 1926 Subpart T specifically addresses demolition work,
establishing safety requirements such as pre-demolition surveys,
structural stability precautions, and worker protection measures.
3. Before beginning demolition, what must be verified regarding all
utility services connected to the structure?
A. They are still active to support emergency lighting
B. They are partially operational for inspection purposes
C. They are disconnected, shut off, and physically verified as inactive
D. They are rerouted temporarily to adjacent structures
Answer: C
All utilities including gas, electricity, water, and sewer must be fully
shut off and verified to prevent explosions, electrocution, flooding,
and other serious hazards during demolition.
,4. What is the primary purpose of a demolition safety plan prior to
commencement of work?
A. To outline project profitability and material resale value
B. To establish a detailed schedule for worker shift rotations
C. To identify hazards and define control measures to protect workers
and the public
D. To determine the fastest method of structure removal
Answer: C
A demolition safety plan systematically identifies hazards such as
structural instability and hazardous substances and establishes
controls to reduce risks to workers, the public, and surrounding
properties.
5. Which condition most strongly indicates a structure is unsafe and may
require immediate stabilization before demolition proceeds?
A. Fresh exterior paint and recent renovations
B. Uniform wall alignment and intact flooring
C. Visible cracking, sagging floors, and structural deformation
D. Presence of decorative architectural features
Answer: C
Cracks, sagging, tilting, and deformation are key indicators of
structural instability, suggesting the building may collapse
unexpectedly during demolition activities.
, 6. What is the primary reason for conducting a pre-demolition
engineering survey?
A. To estimate the resale value of salvaged materials
B. To determine workforce payroll requirements
C. To identify hazards such as structural weaknesses, utilities, and
hazardous materials
D. To design the post-demolition construction layout
Answer: C
A pre-demolition survey is conducted to locate hazards including
asbestos, lead, utilities, and structural risks to ensure safe demolition
planning and execution.
7. In demolition operations, what is the most appropriate method for
handling gas lines prior to structural removal?
A. Leaving them closed at interior valves only
B. Cutting and sealing them during demolition
C. Having qualified personnel shut off and cap them at the source
D. Covering exposed pipes with protective tape
Answer: C
Gas lines must be properly shut off and capped by qualified
professionals to eliminate risks of leaks, fires, and explosions during
demolition work.
8. Which type of demolition is generally preferred in densely populated
urban areas due to its controlled nature?
