1On a two-point adjustable suspension scaffold (swing stage), what minimum safety factor must the suspension wire ropes provide?
A.4 times the rated load
B.6 times the rated load
C.8 times the rated load
D.10 times the rated load
Explanation: Under OSHA 1926.451(a)(4), suspension ropes on suspension scaffolds must be capable of supporting at least 6 times the maximum intended (rated) load. This higher factor than the 4:1 used for general scaffold structure reflects the critical, single-line-of-support nature of suspended work.
2Counterweights used to balance an adjustable suspension scaffold must be capable of resisting at least how much of the tipping moment at the rated load of the hoist?
A.1.5 times
B.2 times
C.4 times
D.6 times
Explanation: OSHA 1926.451(d)(3)(i) requires counterweights to resist at least 4 times the tipping moment imposed by the scaffold operating at the rated load of the hoist, or 1.5 times the tipping moment at stall load, whichever is greater. The 4:1 rated-load figure normally governs.
3Counterweights used on suspension scaffold outrigger beams must be:
A.Flowable materials such as sand or water that distribute evenly
B.Made of non-flowable material and secured by mechanical means to the outrigger beam
C.Any heavy material as long as the total weight is correct
D.Removed during high winds and replaced afterward
Explanation: OSHA 1926.451(d)(3)(ii)-(iv) requires counterweights to be made of non-flowable material (no sand, water, or other flowable masses) and to be secured by mechanical means to the outrigger beam to prevent accidental displacement. Loose or flowable weights can shift or be removed, defeating the balance.
4Tiebacks on a suspended scaffold support system must be:
A.A single tieback installed at any convenient angle
B.Installed perpendicular to the face of the building, or opposing angle tiebacks used
C.Secured to standpipes or vent piping when structural members are unavailable
D.Of lower strength than the suspension ropes to act as a fuse
Explanation: OSHA 1926.451(d)(3)(viii)-(x) requires tiebacks to be installed perpendicular to the building face, or opposing-angle tiebacks where perpendicular is not possible; single tiebacks installed at an angle are prohibited. Tiebacks must be equivalent in strength to the suspension ropes and secured to a sound structural anchorage.
5Suspension scaffold support devices such as outrigger beams, cornice hooks, and parapet clamps must rest on surfaces capable of supporting at least how many times the load imposed by the scaffold?
A.2 times
B.3 times
C.4 times
D.6 times
Explanation: OSHA 1926.451(d)(3)(v) requires that surfaces supporting suspension devices be capable of supporting at least 4 times the load imposed by the scaffold operating at the greater of the rated load of the hoist or 1.5 times the stall capacity. Bearing blocks are used to distribute the load.
6What is the primary U.S. consensus standard that governs the design and manufacture of mast climbing work platforms (MCWPs)?
A.ANSI/SAIA A92.9
B.ASME B30.5
C.ANSI A10.8
D.ANSI/SAIA A92.20
Explanation: ANSI/SAIA A92.9 is the consensus standard covering the design, manufacture, and use of mast climbing work platforms. OSHA regulates MCWPs as scaffolds under Subpart L but references the A92.9 standard for MCWP-specific provisions.
7When a mast climbing work platform exceeds the manufacturer's free-standing height, the erector must:
A.Add counterweights to the base only
B.Install tie-ins to the structure at the intervals specified in the manufacturer's manual
C.Reduce the platform load to one-half of rating
D.Operate the platform only on windless days
Explanation: Mast climbers are stabilized by tie-ins (wall ties) to the structure at the spacing and free-standing heights given in the manufacturer's engineered manual. Beyond the free-standing height, ties are mandatory to control mast deflection and overturning, exactly as with frame scaffolds beyond a 4:1 height-to-base ratio.
8On a single-point or two-point suspension scaffold, employees must be protected from falls by:
A.A guardrail system only
B.A personal fall arrest system only
C.Both a guardrail system and a personal fall arrest system
D.Either a guardrail or fall arrest, at the erector's discretion
Explanation: OSHA 1926.451(g)(1)(ii) requires that each employee on a single-point or two-point adjustable suspension scaffold be protected by BOTH a personal fall arrest system AND a guardrail system. The redundant protection reflects the elevated risk of suspended work where the platform itself can fail.
9On a suspension scaffold, a vertical lifeline for a personal fall arrest system must be anchored to:
A.The scaffold platform itself
B.The suspension rope or hoist
C.A structural anchorage independent of the scaffold support and suspension ropes
D.The outrigger beam counterweight
Explanation: OSHA 1926.451(g)(3)(i) requires that on suspension scaffolds the vertical lifeline be fastened to a fixed, safe point of anchorage independent of the scaffold and protected against cutting/abrasion. If the scaffold or its ropes fail, the worker's fall arrest must remain anchored to the structure, not the failing system.
10A heavy-duty scaffold platform is designed and constructed to carry a working load of at least:
A.25 pounds per square foot
B.50 pounds per square foot
C.75 pounds per square foot
D.100 pounds per square foot
Explanation: Heavy-duty scaffolds are rated for 75 psf, intended for stone setting, masonry, and other heavy material storage. Light-duty is 25 psf (painters/inspectors) and medium-duty is 50 psf (general construction). The platform must still support 4 times this intended load.
