Scaffolds and Temporary Work Platforms

Safe scaffold use depends on correct design, competent erection and inspection, complete platforms, suitable access and disciplined load control.

A scaffold is a temporary structure, not site furniture. Find six setup or use conditions that require correction.

Reveal the six planning cues
  1. Unstable foundation

    A base is set on unsuitable material without adequate support.

  2. Incomplete edge protection

    An open platform edge is missing a required midrail.

  3. Mismatched components

    Incompatible parts can compromise the system’s intended performance.

  4. Falling-object exposure

    Loose material is stored near the platform edge.

  5. Improper access

    A worker is climbing cross braces instead of using the provided access.

  6. Vehicle conflict

    Mobile equipment is operating close enough to strike or destabilize the scaffold.

Fun facts

Three details worth remembering

  1. California’s common railing trigger is 7½ feet

    Scaffold type, location and listed exceptions still matter, so the applicable order must control the final setup.

  2. Design loading includes a four-times factor

    California requires a scaffold to support its own weight and four times the maximum intended working load.

  3. Containment can act like a sail

    Plastic, mesh and debris netting can materially increase wind forces on ties, anchors and the supporting structure.

Read the detailed planning guidanceConcise, source-grounded project considerations

Select and design for the actual work

The scaffold type, duty, foundation, height, tie-in, access and loading should match the task and manufacturer requirements. Under Cal/OSHA §1637, the scaffold must support its own weight and four times the maximum intended working load applied or transmitted to it.

Control erection and modification

Erection and dismantling should be performed under the supervision and direction of a qualified person. Required ties, bracing, platforms and access should be installed in the proper sequence, and field modifications should not be improvised.

Inspect before use and after change

Scaffold components and planks should be inspected for damage and defects. Reinspect after alteration, relocation, impact, weather or another event that could affect strength, stability, access or fall protection.

Use within the released configuration

Do not exceed the intended load, remove components, climb cross-bracing or use makeshift platforms. Maintain suitable access, guardrails or other required fall protection, falling-object controls and separation from electrical or equipment hazards.

Work height, loading, foundation, tie-in and duration determine whether scaffolding is the right solution.
