Scaffold Erection and Dismantling Safety

Key Hazards

• Falls while platforms and guardrails are incomplete
• Scaffold instability from missing braces, ties, pins, or bases
• Components or tools dropped onto workers below
• Workers struck or pinched while handling frames and planks
• Contact with overhead power lines
• Premature removal of supports during dismantling

2–3 Minute Talk Script

Scaffold Erection and Dismantling Safety requires workers to recognize the task-specific hazards before work begins and to use the controls established for the project.

Erection and dismantling should follow the scaffold manufacturer's requirements and the direction of a competent person who evaluates access, fall protection, stability, sequence, and site conditions.

The supporting surface, base plates, mud sills, casters, frames, posts, and first level should be established level, plumb, square, and stable before height is added.

Braces, pins, couplers, ties, guys, outriggers, platforms, and access components should be installed in the planned sequence so the scaffold remains stable throughout the work.

Workers should use the fall-protection and safe-access methods selected by the competent person for the specific scaffold and erection stage.

A controlled area should keep others away from falling components, and materials should be raised, lowered, and handed off without throwing or overreaching.

Dismantling should proceed in the reverse planned sequence without removing ties, braces, or support components before the upper structure and loads they protect are removed.

Work should stop when the scaffold shifts, wind or weather becomes unsafe, electrical clearance is threatened, components do not fit correctly, or the planned sequence cannot be followed.

Safety Reminders

• Follow competent-person direction and manufacturer instructions.
• Build from a stable, level foundation.
• Install braces, pins, ties, and platforms in sequence.
• Use the selected access and fall-protection method.
• Control the area below for falling components.
• Never throw scaffold parts.
• Remove ties and braces only in the planned dismantling sequence.

Ask the Crew

• Who is the competent person directing the work?
• What erection and dismantling sequence will be used?
• How will workers be protected before guardrails are complete?
• How will components be moved without exposing workers below?
• What weather or stability change will stop the work?
