What steps should be taken if panels are to be erected from outside of the building?

• A. The perimeter should be inspected prior to erection
• B. The perimeter should be cleared from any obstructions or interferences
• C. Both A and B
• D. Neither A nor B

Answer: (C)

Preparing to erect panels from outside requires two safety-focused actions. First, inspect the perimeter prior to erection to identify hazards or constraints that could affect crane swing, rigging, and access—check for overhead hazards, utilities, vehicles, equipment, ground conditions, and any openings or obstacles near where the panel will travel and land. Second, clear the perimeter of any obstructions or interferences so the crane, rigging, and crew have a safe, unobstructed work area and panels can be moved without risk of collision or damage. Doing both ensures proper planning, reduces the chance of incidents, and protects both people and equipment.
