01REQUIRED

Competent Person Inspection

  • Arrange a visible-defect inspection before each shift.
  • Reinspect after alterations or events affecting integrity.
  • Never use an uninspected scaffold.
02REQUIRED

Tag and Use Status

  • Verify the current inspection tag or use status.
  • Read all restrictions and special precautions.
  • Do not access a scaffold marked out of service.
03REQUIRED

Foundation and Stability

  • Verify base plates and firm supporting foundations.
  • Check ties, braces and stabilizing components.
  • Stop work if settlement, leaning or movement is found.
04REQUIRED

Fully Decked Platform

  • Fully plank working platforms; the OSHA general limit for adjacent platform gaps is 1 in (2.5 cm).
  • Verify exceptions against 1926.451(b)(1) and the appropriate design; do not assume wider gaps are allowed.
  • Do not use loose, cracked or damaged units; stop use where gaps are hazardous.
05REQUIRED IF

Guardrail System

Applies when: As required by the scaffold type’s fall-protection rules

  • Verify toprails and midrails are complete.
  • Protect all exposed sides and ends.
  • Never remove or modify guardrails without authorization.
06REQUIRED

Safe Access

  • Use an approved ladder, stair tower or access system.
  • Never climb scaffold cross-braces for access.
  • Keep access trapdoors closed after passing.
07REQUIRED

Load and Material Control

  • OSHA general design rule: scaffolds/components support their own weight plus at least 4× maximum intended load.
  • Check separate rules for special types; 4× is not permission to increase the working load.
  • Do not exceed approved working capacity; secure materials evenly and keep access clear.
08REQUIRED IF

Prevent Dropped Objects

Applies when: There is a falling-object hazard

  • Use toe boards, screens or suitable falling-object protection.
  • Keep tools and materials away from platform edges.
  • Barricade the area below and prevent unauthorized entry.

Stop work immediately if platforms or required fall protection are incomplete, or access is unsafe

The scaffold is leaning, settled or unstable

Components are damaged or connections are loose

The scaffold is overloaded or materials are stored unsafely

Critical Controls

4×

OSHA general design: own weight + 4× load; not working capacity

≤1 in

OSHA general adjacent gap: 2.5 cm; verify .451(b)(1) exceptions

>2 ft

Level difference >0.6 m: suitable access required; do not climb braces
