Scaffold inspection checklist: who, when and what to record

Who may inspect a scaffold?

Both countries put the job on a competent person, but they define the duty differently.

• UK: regulation 12 of the Work at Height Regulations 2005 describes an inspection as a visual or more rigorous check by a competent person, as appropriate for safety purposes. HSE's scaffolding guidance says competence may be assessed under the Construction Industry Scaffolders Record Scheme (CISRS), and that a non-scaffolder such as a site manager who has attended a scaffold inspection course could be competent to inspect a basic scaffold. The user or hirer of the scaffold is responsible for making sure the inspections happen.
• US: 29 CFR 1926.451(f)(3) requires a competent person to inspect for visible defects. Under (f)(7), erecting, moving, dismantling or altering a scaffold may only happen under the supervision and direction of a competent person.

In practice this means the person who signs the inspection must understand the scaffold in front of them. A tube-and-fitting birdcage, a system scaffold with a loading bay and a sheeted scaffold with a hoist are three different inspections. The wider rule sets behind these duties are in UK scaffolding regulations and TG20 and OSHA scaffolding requirements.

When must a scaffold be inspected?

The 7-day rule is in the regulation itself, not only in HSE guidance, and it only covers platforms from which a person could fall 2 metres or more. A scaffold left standing over a weekend storm is not "still covered" by Friday's inspection: the storm itself triggers a new one under 12(3)(b).

What is a scaffold handover certificate?

The Work at Height Regulations require the inspection and the Schedule 7 report; they do not mention a handover certificate. The certificate comes from industry practice: the NASC's guidance SG35:21 covers how a scaffold is formally handed over to the customer or site team, with completion checks, documentation and the first statutory inspection after handover. NASC describes its handover certificate as a formal record that the scaffold has been erected, inspected and deemed safe, signed on handover to transfer responsibility to the customer, and tied to the design or the TG20/TG30 compliance sheet. For the user it is the starting point, not the end: the 7-day clock under regulation 12(4) starts with the first inspection, and the user's own inspections follow from there.

The checklist: what to check, from the ground up

Walk the scaffold in the order the loads travel: ground, base, frame, ties, platforms, edges, access, then what is on it. Each line names the UK or US rule behind it, except two marked as site practice, which no clause prescribes; where the rule is the manufacturer's instructions or the TG20:21 compliance sheet, check against that document, not against memory.

1. Foundation and base

2. Standards, ledgers and bracing

• The scaffold still matches the configuration it was built to: a generally recognised standard configuration such as a TG20:21 compliance sheet, or a design with a note of calculations (UK Schedule 3, Part 2, para 7, in the Work at Height Regulations).
• Ledgers, transoms, façade bracing and plan bracing present at every lift shown in that configuration; none removed "for access".
• Every coupler or wedge tight, and no components from other systems unless the design allows it.

3. Ties and anchors

Count the wall ties against the tie pattern in the compliance sheet or design, not against what looks enough. In the US, 1926.451(c)(1)(ii) requires ties installed to the manufacturer's recommendations and sets a minimum vertical and horizontal spacing. If sheeting, debris netting or a signboard has been added since the scaffold was handed over, the scaffold is no longer the one that was designed; the tie pattern must come from a design for the sheeted scaffold.

4. Platforms and gaps

• The deck suits the loads and lets people work and pass in safety (UK Schedule 3, Part 2, para 10).
• Fully boarded or decked at every working lift, with boards or system decks seated and secured against uplift.
• US: platform units and the space between platform and uprights no more than 1 inch wide, 1926.451(b)(1)(i), unless the employer can show a wider gap is necessary; front edge no more than 14 inches from the face of the work without guardrails, (b)(3).

5. Side protection and toe boards

• UK: main guardrail at least 950 mm high, no unprotected gap over 470 mm, and a toe board that is suitable and sufficient, Schedule 2, para 3.
• US: top rail between 38 and 45 inches above the platform for supported scaffolds put into service after 1 January 2000, 1926.451(g)(4)(ii).
• Brick guards or mesh where materials are stacked above toe-board height, so the edge protection prevents the fall of any material or object (UK Schedule 2, para 2(c)).

6. Access, loads, signage and sheeting

How do you record a scaffold inspection?

In the UK, the inspection report is a legal document. Schedule 7 lists what it must contain:

1. The name and address of the person for whom the inspection was carried out.
2. The location of the work equipment inspected.
3. A description of the work equipment inspected.
4. The date and time of the inspection.
5. Details of any matter identified that could give rise to a risk to health or safety.
6. Details of any action taken as a result.
7. Details of any further action considered necessary.
8. The name and position of the person making the report.

Regulation 12(7) requires the report before the end of the working period in which the inspection was completed, and a copy to the person it was done for within 24 hours. Under 12(8) the report stays on site until the construction work is finished, then at an office for 3 months. HSE adds that corrective actions belong in the report even when they were done straight away, because they show recurring problems.

OSHA's scaffold standard sets the duty to inspect but no report format. Keeping a short shift log signed by the competent person is the simplest way to show the check happened. Whatever the form, a useful record names the scaffold by location and grid line, lists defects with the bay where they were found, and states whether the scaffold was left in use, partly closed or fully closed.

What happens when a scaffold fails inspection?

OSHA is direct: a damaged or weakened component must be repaired or replaced immediately, braced, or the scaffold removed from service until it is repaired, 1926.451(f)(4). In the UK the same logic sits in Schedule 7, items 5 to 7: the report has to say what was wrong, what was done and what still needs doing, and Schedule 3 requires warning signs and barriers on any part not available for use. On the scaffold, that means the tag changes to "do not use", the access is barred, and the scaffold contractor is called back. Users should never fix ties, boards or rails themselves unless they are competent and authorised to alter that scaffold. A ScaFix model shows where the planned ties, decks and guardrails should be, which you can hold against the scaffold on the walk-round; how it is built is on the methodology page, and it is not an inspection.

In the UK the Health and Safety Executive enforces the Work at Height Regulations; in the US OSHA enforces 29 CFR 1926.451. This checklist is planning information, not structural approval: the manufacturer's instructions, a TG20:21 compliance sheet or a bespoke design decide how a scaffold must be built, and a competent person must inspect it before anyone uses it.
