Scaffold Safety Quiz
Questions: 16 · 10 minutes
1. Which statement best describes scaffold safety responsibility?
The scaffold supplier remains solely responsible after erection
Each worker decides independently whether a scaffold needs inspection
Responsibility belongs only to the person who signs the scaffold tag
The employer or controlling organization must provide required systems and oversight, designated competent people perform assigned inspections, and all users should follow controls and report hazards
2. A severe storm affected a site overnight, although the scaffold looks unchanged from ground level. What is the appropriate next step?
Keep it out of service until the required post-event inspection confirms it can be used
Let the most experienced trade worker test the platform by walking on it
Resume work because no damage is immediately visible
Tighten only the connections that workers can reach from the ground
3. Which foundation condition is most appropriate for a supported scaffold?
Loose fill that can settle evenly beneath all legs
A firm, level, load-bearing surface with approved base components and support
A sloped surface corrected by stacks of scrap lumber and bricks
Any paved surface, even if voids or undermining are visible beneath it
4. A worker is about to climb a mobile scaffold that has been moved into position. What basic check is essential?
Confirm that another worker is holding one side of the scaffold
Confirm that the casters are locked and the scaffold is stable and properly supported
Remove diagonal braces so the unit can flex on uneven flooring
Load materials first so their weight keeps the scaffold in place
5. A task requires personal fall-arrest equipment on a scaffold. Which anchorage approach is appropriate?
Attach to any nearby guardrail because it is already intended for fall protection
Connect two workers to each other so either can arrest the other's fall
Use an anchorage designated for that purpose under the applicable fall-protection plan, with compatible equipment and required clearance
Tie off to the nearest loose scaffold component to preserve movement
6. A planned scaffold location is near overhead electrical conductors. What should happen first?
Cover the scaffold rails with nonconductive tape and proceed cautiously
Assign a worker to watch the conductors while the scaffold is erected
Begin work only when the conductors look dry
Stop and have the required clearance or de-energization controls confirmed by the responsible site and utility authorities
7. People must pass beneath a scaffold where hand tools could fall. Which approach best addresses the hazard?
Use suitable falling-object controls—such as toe boards, screens, secured tools, canopies, or a restricted area—as required by the hazard assessment
Ask people below to walk quickly and avoid looking upward
Rely solely on hard hats regardless of the objects or drop distance
Move tools farther from the edge but leave loose materials unchanged
8. Which access method is generally appropriate for reaching a scaffold work platform?
Using a nearby stack of materials as temporary steps
Climbing the scaffold's cross braces while maintaining three points of contact
A designed and properly installed ladder, stair tower, ramp, or equivalent access system
Being lifted on the platform by a material-handling device not designed for people
9. A scaffold has just been erected for a new work area. What should happen before workers begin using it?
The first user should climb it slowly and report any movement
The delivery paperwork should be checked as the sole approval step
A competent person should inspect it as required by applicable rules and the site plan
Workers should wait until materials have been loaded to test its stability
10. A brace obstructs the exact spot where a worker wants to install a component. What should the worker do?
Remove the brace briefly and reinstall it at the end of the shift
Replace the brace with a rope of similar length
Leave the brace in place and request an authorized modification consistent with the approved design and instructions
Ask a coworker to hold the frame while the brace is absent
11. What does a scaffold status tag or access indicator demonstrate?
It guarantees that conditions will remain safe for the entire shift
It transfers inspection responsibility to each individual user
It confirms that the scaffold can support any materials that fit on the platform
It communicates status under the site's system but does not replace required inspections or personal hazard checks
12. While working, someone notices a newly bent brace and unusual scaffold movement. What is the best immediate response?
Reduce the pace of work and observe whether the movement becomes worse
Leave the affected area safely, prevent further use if possible, and report it for competent assessment
Finish the current task before reporting the condition
Straighten the brace with a tool while the scaffold remains occupied
13. Before a shift, you notice that a scaffold leg has no base plate and has sunk slightly into the soil. What is the best response?
Keep people off it, restrict access, and report it for competent evaluation and correction
Use the scaffold only for light tasks until the next formal inspection
Place loose bricks beneath the leg to restore its height
Move stored materials to the opposite side to balance the scaffold
14. What is the primary safety purpose of a scaffold guardrail system?
To help prevent people from falling from open sides and ends
To display the scaffold's maximum intended load
To level the scaffold on uneven ground
To stop all tools and materials from falling below
15. A crew plans to place workers, tools, and masonry materials on one scaffold level. How should loading be assessed?
Count only the masonry because people and hand tools are excluded
Use the scaffold's own weight as its allowable working load
Assume the load is acceptable if the platform does not visibly bend
Add the expected people, tools, equipment, and materials, then keep the total and its distribution within approved limits
16. A platform plank has shifted and now leaves a wider gap than the scaffold design allows. What should be done?
Mark the gap with bright tape and continue working
Stop using the affected area until the platform is properly secured and restored to its approved arrangement
Limit the platform to one worker at a time
Cover the gap with a loose sheet of plywood
