1. What is the primary purpose of conducting a pre-demolition
inspection?
a. To determine the color of the building
b. To identify structural conditions, hazards, and materials requiring
special handling
c. To estimate the resale value of the property
d. To determine the number of workers needed for painting
Answer: b. To identify structural conditions, hazards, and materials
requiring special handling
Rationale: A pre-demolition inspection establishes the condition of the
structure and identifies hazards such as unstable components,
,hazardous materials, utilities, and adjacent structures. This
information is essential for developing a safe demolition plan.
2. Before demolition begins, which utility-related action is most
important?
a. Increase the electrical service
b. Disconnect, cap, or otherwise make safe all relevant utilities
c. Remove the building's light fixtures only
d. Turn on all water supplies
Answer: b. Disconnect, cap, or otherwise make safe all relevant
utilities
Rationale: Active electrical, gas, water, steam, sewer, or other utility
services can create serious hazards during demolition. Utilities must
be properly identified and made safe before work begins.
3. Which condition presents the greatest immediate structural
concern during demolition?
a. Faded exterior paint
b. Loose floor covering
c. An unexpectedly weakened load-bearing wall
d. Broken interior shelving
Answer: c. An unexpectedly weakened load-bearing wall
,Rationale: Load-bearing components support portions of the
structure. Removing or destabilizing them without proper sequencing
can cause an uncontrolled collapse, endangering workers and nearby
persons.
4. What is the main purpose of establishing a controlled demolition
zone?
a. To store employee vehicles
b. To keep unauthorized people away from demolition hazards
c. To provide a location for office equipment
d. To display construction materials
Answer: b. To keep unauthorized people away from demolition
hazards
Rationale: Demolition creates falling-object, collapse, equipment,
dust, and debris hazards. A controlled zone restricts access and helps
protect workers, visitors, pedestrians, and the public.
5. When demolishing a structure from the top down, which principle
should generally guide the sequence?
a. Remove lower supports first
b. Remove structural elements in a planned sequence that maintains
stability
, c. Remove all exterior walls simultaneously
d. Start by cutting every column
Answer: b. Remove structural elements in a planned sequence that
maintains stability
Rationale: Controlled sequencing prevents unintended load
redistribution and collapse. Demolition should proceed according to
an engineered or competent-person-developed plan appropriate to
the structure.
6. Why should demolition debris be removed regularly?
a. To make the building look cleaner
b. To reduce trip hazards, excessive loading, and interference with
operations
c. To increase the building's resale value
d. To eliminate the need for protective equipment
Answer: b. To reduce trip hazards, excessive loading, and interference
with operations
Rationale: Accumulated debris can obstruct access, overload floors,
create fall and trip hazards, and interfere with workers and
equipment. Controlled debris removal improves safety and efficiency.
