During the erection of a supported scaffold on a commercial construction
project in Virginia, which action best complies with accepted scaffold safety
practices when the soil conditions are soft and subject to settlement?
A. Place scaffold frames directly on compacted soil
B. Use wood scraps beneath only the corner legs
C. Install base plates and adequate mud sills beneath all load-bearing legs
D. Increase platform width instead of improving support
Rationale: Supported scaffold legs must rest on a firm foundation capable
of carrying imposed loads. Base plates and properly sized mud sills help
prevent settlement, movement, and instability during erection.
, 2. Which individual has primary responsibility for determining whether
scaffold erection, dismantling, alteration, or inspection activities are
being performed safely?
A. Building owner
B. Material supplier
C. Competent person
D. Local building inspector
Rationale: A competent person is qualified to identify existing and
predictable hazards and has authority to take corrective action regarding
scaffold operations.
3. When scaffold components from different manufacturers are
considered for use on the same scaffold system, what is the most
appropriate action?
A. Always combine them if dimensions appear similar
B. Use them only on residential projects
C. Verify compatibility and structural integrity before use
D. Paint them the same color before installation
Rationale: Components from different manufacturers may only be used
together when compatibility and structural performance are assured.
Improper mixing can create structural weaknesses.
4. Which of the following conditions most likely requires immediate
removal of a scaffold plank from service?
,A. Minor paint stains
B. Surface dust accumulation
C. Significant cracking or structural damage
D. Manufacturer labeling
Rationale: Damaged planks may fail under load and create a serious fall
hazard. Structural defects are grounds for immediate removal from service.
5. The primary purpose of cross-bracing on a frame scaffold is to:
A. Increase platform width
B. Provide lateral stability and rigidity
C. Improve worker comfort
D. Eliminate guardrail requirements
Rationale: Cross-bracing helps maintain scaffold geometry and resists
lateral forces that could otherwise cause instability or collapse.
6. Before workers are allowed to use a newly erected scaffold, the
structure should be:
A. Painted
B. Covered with tarps
C. Inspected by a competent person
D. Approved by the project owner
Rationale: Inspection by a competent person helps verify that the scaffold
is properly erected, stable, and safe for occupancy.
, 7. What is the most important reason for maintaining proper tie-ins
between a scaffold and an adjacent structure?
A. To improve appearance
B. To reduce material costs
C. To prevent overturning and excessive movement
D. To increase platform storage space
Rationale: Ties secure the scaffold to the structure and significantly
improve resistance to wind and lateral forces.
8. During scaffold erection, workers should climb scaffold frames only
when:
A. They are carrying materials
B. No ladders are available
C. The frame is specifically designed and approved for climbing access
D. The scaffold height is less than 20 feet
Rationale: Safe access methods must be provided. Not all scaffold frames
are intended to serve as climbing devices.
9. Which factor has the greatest influence on the load capacity of a
scaffold platform?
A. Color of the planks
B. Project duration
