  1. When erecting a tubular welded frame scaffold, at what height must the first set of cross braces be installed?

    Answer: At the base of the first frame section before adding additional frames

    Cross braces must be installed at the base of the first frame section to provide lateral stability before additional frames are stacked.

  2. What is the minimum wire gauge for wire used to secure scaffold planks in place?

    Answer: 14 gauge

    OSHA requires a minimum of 14-gauge wire when wire is used to secure scaffold planking.

  3. A scaffold is being used near overhead power lines. According to OSHA 1926.502, what is the minimum safe distance from uninsulated power lines carrying up to 50 kV?

    Answer: 10 feet

    OSHA requires scaffolds to be erected at least 10 feet away from uninsulated power lines rated up to 50 kV.

  4. Which condition makes a scaffold plank unfit for use?

    Answer: Split ends extending more than the plank's thickness

    Split ends that extend beyond the plank's thickness compromise structural integrity and the plank must be removed from service.

  5. During a scaffold inspection after a storm, you notice one upright has settled approximately 1 inch into soft soil. What is the correct action?

    Answer: Remove all workers immediately and re-level and re-plumb before resuming work

    Any settlement that causes the scaffold to go out of plumb requires immediate evacuation and correction before work resumes.

  6. What is the purpose of the 'green tag' system commonly used in scaffold management programs?

    Answer: To show that a competent person has inspected the scaffold and it is safe for use

    A green tag indicates a competent person has inspected the scaffold and authorized it for safe use.

  7. When must scaffold erectors wear personal fall arrest systems (PFAS) or be protected by a safety net?

    Answer: Whenever it is technically and economically feasible to do so

    OSHA 1926.502 requires fall protection for scaffold erectors when it is both technically and economically feasible, based on a site-specific analysis.
