The SAIA Journeyperson Scaffold Erector — Level 2 is the intermediate, 2nd-year tier of the Scaffold & Access Industry Association's accredited erector program. It builds on Level 1 to cover systems and tube-and-clamp erection, cantilevers and returns, an introduction to two-point suspended/swing-stage scaffolds, advanced ties and bracing, load calculations, complex access, and inspection — all grounded in OSHA 1926 Subpart L. The written exam requires 70% to pass and is paired with a hands-on practical evaluation; the question count and fee are set by the SAIA-accredited training provider. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1On a tube-and-clamp scaffold, which coupler is used to make a load-bearing 90-degree connection of a ledger to a standard?
A.Putlog coupler
B.Right-angle (double) coupler
C.Swivel coupler
D.Sleeve coupler
Explanation: A right-angle coupler, also called a double coupler, is the structural fitting that connects two tubes at a fixed 90-degree angle and carries vertical load, such as a ledger to a standard. It has the highest slip resistance of the right-angle fittings used in load-bearing positions.
2Which coupler must be used to attach a diagonal brace tube to a vertical standard on a tube-and-clamp scaffold?
A.Right-angle coupler
B.Swivel coupler
C.Putlog coupler
D.Band-and-plate coupler
Explanation: A swivel coupler has a rotating center pivot that lets two tubes be joined at any angle from 0 to 90 degrees, which is exactly what diagonal/cross bracing requires. Using a fixed right-angle coupler for a brace would not allow the needed angle.
3In tube-and-clamp scaffold terminology, what is the horizontal tube that runs parallel to the structure face and ties the standards together at each lift called?
A.Transom
B.Ledger
C.Standard
D.Putlog
Explanation: A ledger is the long horizontal tube that runs lengthwise parallel to the face of the building and connects the standards at each lift, providing the support that transoms rest on. Ledgers establish the lift height and tie the frame together horizontally.
4Per OSHA 1926.451(a)(1), each scaffold and scaffold component must be capable of supporting, without failure, its own weight plus at least how many times the maximum intended load?
A.2 times
B.3 times
C.4 times
D.6 times
Explanation: OSHA Subpart L requires each scaffold and component to support its own weight and at least 4 times the maximum intended load applied or transmitted to it. This 4:1 safety factor is the baseline design rule for supported scaffolds and components.
5What is the minimum safety factor required for each suspension rope and its connecting hardware on a suspension scaffold under OSHA 1926.451(a)(3)?
A.4 times the maximum intended load
B.5 times the maximum intended load
C.6 times the maximum intended load
D.8 times the maximum intended load
Explanation: Suspension ropes, including connecting hardware, must support at least 6 times the maximum intended load applied or transmitted to that rope. The higher 6:1 factor reflects the life-safety consequence of a single suspension rope failure.
6A supported scaffold has a base width of 5 feet. At what height does OSHA's height-to-base ratio require it to be restrained from tipping by guying, tying, or bracing?
A.More than 10 feet
B.More than 15 feet
C.More than 20 feet
D.More than 30 feet
Explanation: OSHA requires supported scaffolds to be restrained from tipping when the height exceeds 4 times the minimum base width. With a 5-foot base, 4 x 5 = 20 feet, so guying/tying/bracing is required above 20 feet. This 4:1 ratio is the key stability trigger.
7For a supported scaffold 3 feet wide or less, what is the maximum VERTICAL spacing between ties/guys per OSHA's guying requirements?
A.Every 20 feet
B.Every 26 feet
C.Every 30 feet
D.Every 35 feet
Explanation: For scaffolds 3 feet wide or less, vertical ties/guys must be installed at intervals not to exceed every 20 feet. Scaffolds wider than 3 feet may space vertical ties up to every 26 feet. Horizontal spacing for both is not to exceed 30 feet.
8What is the maximum HORIZONTAL spacing between ties on a supported scaffold under OSHA Subpart L?
A.20 feet
B.26 feet
C.30 feet
D.40 feet
Explanation: Horizontal tie spacing on supported scaffolds must not exceed 30 feet, measured from one end. This applies regardless of scaffold width, while the vertical interval depends on whether the scaffold is over or under 3 feet wide.
9A two-point suspended scaffold (swing stage) outrigger beam is being stabilized with counterweights. Which material is acceptable as a counterweight under OSHA?
A.Masonry blocks
B.Rolls of roofing felt
C.Sand or gravel in containers
D.Manufactured counterweights designed for the purpose
Explanation: OSHA 1926.451(d) requires that only items specifically designed and labeled as counterweights be used. Counterweights must be made of non-flowable material and be secured by mechanical means to the outrigger beam so they cannot be accidentally removed.
10On a two-point suspended scaffold, counterweights must resist at least how many times the tipping moment at the rated load of the hoist?
A.1.5 times
B.2 times
C.4 times
D.6 times
Explanation: Counterweights used to balance adjustable suspension scaffolds must resist at least 4 times the tipping moment imposed at the rated load of the hoist, or at least 1.5 times the tipping moment at the stall load, whichever is greater. The 4x figure is the rated-load criterion.
