The SAIA Scaffold Competent Person credential, offered by the Scaffold & Access Industry Association through accredited training providers, certifies the OSHA 1926 Subpart L competent person responsible for identifying scaffold hazards and taking prompt corrective action. Candidates complete training and pass a multiple-choice written exam (minimum 70%) plus a hands-on practical assessment; the wallet card is generally valid for three years. The role spans frame, tube-and-coupler, systems, suspended, and mobile scaffolds and covers before-each-shift and post-occurrence inspections, the 4:1 component safety factor, 25/50/75 psf duty ratings, the 10-foot fall-protection trigger, guardrails and toeboards, mud sills and base plates, the 4:1 tipping ratio and ties, and safe access. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Under OSHA 1926, what defines a "competent person" with respect to scaffolds?
A.Anyone who has worked on scaffolds for at least one year
B.A person who holds a recognized engineering degree in scaffold design
C.A person capable of identifying existing and predictable scaffold hazards and authorized to take prompt corrective action to eliminate them
D.A safety officer who reviews the daily inspection paperwork from the office
Explanation: OSHA 1926.450(b) defines a competent person as one capable of identifying existing and predictable hazards in the surroundings or working conditions that are hazardous to employees, AND who has authorization to take prompt corrective measures to eliminate them. Both ability to recognize hazards and authority to correct them are required.
2How often must a competent person inspect scaffolds and scaffold components for visible defects?
A.Once per week and after a storm
B.Before each work shift and after any occurrence that could affect structural integrity
C.Only at initial erection and final dismantling
D.Every 30 days as part of the monthly safety audit
Explanation: OSHA 1926.451(f)(3) requires a competent person to inspect scaffolds and scaffold components for visible defects before each work shift, and after any occurrence that could affect the scaffold's structural integrity (such as a struck support leg or a dropped load).
3Each 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 1926.451(a)(1) requires each scaffold and scaffold component to support, without failure, its own weight and at least 4 times the maximum intended load applied or transmitted to it. This 4:1 design safety factor is a core capacity rule for supported scaffolds.
4On a supported scaffold manufactured after January 1, 2000, what is the required height range for the top rail of the guardrail system above the platform?
A.30 to 36 inches
B.36 to 42 inches
C.38 to 45 inches
D.42 to 48 inches
Explanation: OSHA 1926.451(g)(4)(ii) requires the top edge height of top rails (or equivalent members) to be between 38 and 45 inches above the platform surface for scaffolds manufactured and placed in service after January 1, 2000. Older scaffolds may use a 36- to 45-inch range.
5At what height above a lower level must each employee on a scaffold be protected from falling?
A.More than 4 feet
B.More than 6 feet
C.More than 10 feet
D.More than 15 feet
Explanation: OSHA 1926.451(g)(1) requires fall protection for each employee on a scaffold more than 10 feet (3.1 m) above a lower level. Note this differs from the 6-foot trigger in general construction fall protection (Subpart M); for scaffolds the threshold is 10 feet.
6A light-duty scaffold is designed and constructed to carry a working load of how many pounds per square foot (psf)?
A.15 psf
B.25 psf
C.50 psf
D.75 psf
Explanation: Scaffold duty ratings classify intended loads: light-duty = 25 psf (painting, inspection, light repair), medium-duty = 50 psf (general construction, plastering), and heavy-duty = 75 psf (bricklaying, stone, heavy material storage). Light-duty is rated at 25 psf.
7A medium-duty scaffold is rated for what working load?
A.25 psf
B.50 psf
C.75 psf
D.100 psf
Explanation: Medium-duty scaffolds are rated for 50 pounds per square foot and are used for general construction work such as plastering and lathing, typically supporting two workers with tools and a reasonable quantity of material per bay.
8A heavy-duty scaffold, suitable for bricklaying and stone masonry, is rated for what working load?
A.50 psf
B.75 psf
C.100 psf
D.125 psf
Explanation: Heavy-duty scaffolds are rated for 75 pounds per square foot and are designed for bricklaying, stone work, and heavy material storage such as pallets of brick or mortar tubs. The competent person must match the scaffold's duty rating to the work being performed.
9What is the minimum required safety factor for suspension ropes used on suspended scaffolds?
A.2 times the maximum intended load
B.4 times the maximum intended load
C.6 times the maximum intended load
D.10 times the maximum intended load
Explanation: OSHA 1926.451(a)(4) requires suspension ropes and connecting hardware to support, without failure, at least 6 times the maximum intended load applied or transmitted to them. This higher 6:1 factor reflects the greater consequence of a rope failure on a suspended scaffold.
10Supported scaffold poles, legs, posts, frames, and uprights must bear on which of the following?
A.Loose gravel or compacted soil only
B.Base plates and mud sills or another adequate firm foundation
C.Wooden blocks stacked to level the scaffold on uneven ground
D.Concrete masonry units set on end
Explanation: OSHA 1926.451(c)(2) requires supported scaffold poles, legs, posts, frames, and uprights to bear on base plates and mud sills or other adequate firm foundation. Footings must be level, sound, rigid, and capable of supporting the loaded scaffold without settling or displacement.

About the SAIA Scaffold Competent Person Exam

The SAIA Scaffold Competent Person credential certifies the OSHA-required competent person who can identify scaffold hazards and has authority to correct them across frame, tube-and-coupler, systems, suspended, and mobile scaffolds. Training concludes with a multiple-choice written exam requiring 70% to pass, plus a hands-on practical assessment, and the wallet card is generally valid for three years.

Exam sponsor: Scaffold & Access Industry Association (SAIA) accredited training providers. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

SAIA Scaffold Competent Person: Suggested Study Strategy

1Memorize the three load numbers: 4:1 general component safety factor, 6:1 suspension-rope factor, and the 3x hoist stall-load limit
2Know the duty ratings cold: light 25 psf, medium 50 psf, heavy 75 psf, and how to multiply rating by platform area
3Keep the fall numbers straight: scaffolds use a 10-foot fall trigger (not 6 ft), top rails are 38-45 in, and toeboards are at least 3.5 in
4Drill the tie rules: ties begin at the 4:1 height, repeat every 20 ft (narrow) or 26 ft (wide) vertically, and 30 ft horizontally
5Distinguish the competent person (recognize/correct hazards, inspect) from the qualified person (design and load capacity)
6Complete all 100 practice questions and review every miss with the AI tutor before sitting the exam
