OSHA 1926.451 — Scaffolding, Documented

1926.451 is a perennial Top 3 OSHA citation. It governs scaffold capacity, construction, access, fall protection, and falling-object protection. Pair it with 1926.454 (training) and 1926.452 (component-specific rules). ARKVOS documents the daily briefing.

The rule, in plain English

Scaffolds must (1) support 4x intended load, (2) be erected/dismantled under a competent person, (3) have proper access (no climbing cross-bracing), (4) have fall protection above 10 feet, and (5) be inspected each shift.

Most-cited violation patterns

Missing guardrails (1926.451(g)(1)), inadequate planking (full planking, no gaps over 1"), improper access, no daily competent-person inspection, and missing training documentation under 1926.454.

How ARKVOS documents compliance

ARKVOS-1 generates daily scaffold briefings citing 1926.451 and 1926.454. The designated competent person logs the pre-shift inspection with selfie + GPS — every worker on the scaffold acknowledges the briefing.

Penalty math

$16,550 per serious. Scaffold citations are often clustered (capacity + access + fall protection + training), turning a single inspection into a $60,000+ exposure on one site.

Scaffold-type specific talks

Different talks for supported, suspended, mobile, and pole scaffolds — ARKVOS-1 picks the right one based on the day's task.

Frequently asked questions

When is fall protection required on a scaffold?

Above 10 feet — guardrails on supported scaffolds, personal fall arrest on suspended scaffolds (in most cases). 1926.451(g) governs the specifics.

Who is the competent person?

A worker designated by the employer who, by training and experience, can identify scaffold hazards and has the authority to take corrective action. Must inspect before each shift and after any incident that could affect integrity.

What training does 1926.454 require?

Workers must be trained by a qualified person to recognize hazards and use the scaffold safely. Retraining required when scaffold type changes or when an incident reveals a knowledge gap. ARKVOS stores both the initial certification and retraining events.

Can the same person be competent and qualified?

Often yes — but they're different OSHA terms. Competent = recognizes hazards + authority to correct. Qualified = formal degree, certificate, or extensive training in a particular subject. ARKVOS-1 helps document both.
