1. A suspended scaffold supervisor on a major Maryland commercial
construction project is reviewing the setup of a two-point adjustable
suspension scaffold installed on the exterior of a twelve-story building.
During inspection, the supervisor notices that one worker tied off his
personal fall arrest system to the same horizontal lifeline being used
as a tieback support for the scaffold suspension rope. According to
OSHA suspended scaffold safety requirements and accepted Maryland
construction safety standards, what is the MOST appropriate
supervisory action?
A. Allow the worker to continue because both systems are independently
strong enough for dual use
B. Permit the setup only if the scaffold manufacturer approves the
arrangement in writing
C. Require the worker to use a separate independent anchorage for the
personal fall arrest system
D. Allow the arrangement temporarily until the scaffold is repositioned later
in the shift
C. Require the worker to use a separate independent anchorage for the
personal fall arrest system
,Personal fall arrest systems used on suspended scaffolds must be attached
to independent lifelines and separate anchorage points that are not used
to support scaffold suspension systems. Sharing anchorages between
suspension and fall protection systems can create catastrophic failure risks
if one system becomes overloaded or compromised.
2. A Maryland suspended scaffold supervisor is conducting a pre-shift
inspection of a powered scaffold system installed on a downtown
restoration project. The supervisor discovers visible fraying and bird-
caging on one of the wire suspension ropes near the hoist drum. The
scaffold is otherwise functioning normally and production deadlines
are critical. What should the supervisor do FIRST?
A. Continue operations while monitoring the damaged section throughout
the shift
B. Remove the scaffold from service until the damaged rope is replaced
C. Lubricate the damaged section and limit the platform load capacity
D. Cut away the frayed strands and continue scaffold operation cautiously
B. Remove the scaffold from service until the damaged rope is replaced
Damaged suspension ropes with fraying, bird-caging, or broken strands
present an immediate life-safety hazard and require the scaffold to be
removed from service immediately. Continued use could result in sudden
suspension failure, leading to serious injury or death.
3. During erection of a suspended scaffold system on a Maryland bridge
rehabilitation project, the supervisor observes that counterweights are
being improvised using concrete blocks not specifically designed by
the scaffold manufacturer. Which statement best reflects the
supervisor’s proper responsibility?
A. Allow the use of concrete blocks if they are securely tied to the outrigger
beam
B. Permit the arrangement only during low wind conditions
C. Prohibit the use of non-manufacturer-approved counterweights
,immediately
D. Approve the counterweights if the total calculated weight exceeds
minimum requirements
C. Prohibit the use of non-manufacturer-approved counterweights
immediately
Suspended scaffold counterweights must be specifically designed and
approved by the scaffold manufacturer because improvised materials such
as concrete blocks can shift, crack, or fail unexpectedly. Manufacturer-
approved systems ensure predictable load distribution and safe operation.
4. A suspended scaffold crew in Maryland is preparing to work near
energized overhead electrical conductors operating at 15 kV. What
minimum clearance must the scaffold supervisor ensure between the
scaffold and the energized power lines unless the lines are de-
energized?
A. 3 feet
B. 6 feet
C. 10 feet
D. 20 feet
C. 10 feet
OSHA requires a minimum clearance of at least 10 feet from energized
power lines for scaffolds unless greater distances are required for higher
voltages or unless the lines are de-energized and grounded. Maintaining
safe clearance reduces electrocution hazards associated with conductive
scaffold components.
5. A Maryland suspended scaffold supervisor notices workers climbing
the scaffold suspension ropes to gain access to the platform because
ladder access is temporarily unavailable. Which supervisory response
is MOST appropriate?
, A. Allow the practice if workers maintain three points of contact
B. Permit climbing only while the scaffold platform is stationary
C. Stop the activity immediately and provide proper safe access methods
D. Allow experienced workers to climb ropes during emergency situations
only
C. Stop the activity immediately and provide proper safe access methods
Workers are prohibited from climbing scaffold suspension ropes because
doing so exposes them to severe fall hazards and possible rope failure.
Supervisors must ensure safe access using approved ladders, stair towers,
or equivalent access systems.
6. During severe weather conditions in Maryland, wind gusts increase
significantly while workers are operating on a suspended scaffold
along a high-rise façade. What should the scaffold supervisor do?
A. Continue operations if workers wear personal fall arrest systems
B. Lower the platform slightly and continue limited operations
C. Suspend scaffold operations until weather conditions become safe
D. Allow only one worker to remain on the platform during gusts
C. Suspend scaffold operations until weather conditions become safe
High winds can destabilize suspended scaffolds, cause swinging, overload
components, and increase fall risks. Supervisors are responsible for halting
operations whenever weather creates unsafe working conditions.
7. A Maryland suspended scaffold supervisor is evaluating whether a
competent person or a qualified person must design a complex
suspended scaffold support system involving custom rigging
calculations. Which individual is legally required for this task?
A. Any experienced scaffold installer
B. A competent person only
C. A qualified person with demonstrated engineering expertise
D. The site safety manager regardless of qualifications
