Worker allowed on window jack scaffold?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (A)

Window jack scaffolds are narrow, cantilevered platforms designed to reach window openings and are sized for a single worker with their tools. The platform, its guardrails, and its anchorage are built to support one person, so adding a second person would quickly exceed the scaffold’s load capacity and threaten stability. For safety, only one worker should be on a window jack scaffold at a time. If two workers need to operate in the area, switch to a larger scaffold or another form of access that provides proper width, guardrails, and fall protection.
