Are scaffold tags
a legal requirement?

WorkSafe New Zealand’s Good Practice Guidelines are unambiguous. All scaffolds, regardless of height, must have a tag clearly displaying important safety information at access points. There is one narrow exception: minor scaffolds may be excluded where appropriate for the situation, meaning lightweight, portable, single-bay scaffolds with a working platform no higher than 2 metres.

The guidelines also list what the tag has to carry, and it is more than a date. The status of the scaffold — SCAFFOLD SAFE or SCAFFOLD UNSAFE. The name and contact phone number of the certified scaffolder, or the erector if the scaffold is under 5 metres. The purpose or intended use. The duty loadings. The maximum number of platforms or bays that may be loaded. Any limitations on use. And a record of each inspection, including who inspected or altered the scaffold and when.

That last item is the one that catches people out. Inspection records can sit on a separate register or on the tag itself — WorkSafe allows either — but they have to exist and be signed by whoever carried out the inspection, and the record or register must be kept on site.

Safe Work Australia’s Guide to Scaffold Inspection and Maintenance does not mention scaffold tags at all. What it requires is that unauthorised access is prevented while a scaffold is incomplete or unattended — a control, not a specific artefact. How you achieve that is left to you.

SafeWork NSW’s Scaffolding Industry Safety Standard goes further, and its wording is worth reading closely if you have ever been told a tag covers your handover obligations. It describes tags as a useful indicator at the entry point of when the scaffold was last inspected — and then says plainly that they typically do not include the minimum amount of information required for a valid handover certificate, and so cannot be used as one.

For incomplete scaffolds the same standard asks for access to be physically blocked and for signage that clearly indicates access is not allowed, including phone contact details for the responsible scaffold company or authorised person.

One honest caveat: this section reflects Safe Work Australia’s model guidance and the NSW standard, which are the two documents we have read in full. Victoria is not a model WHS jurisdiction and other states publish their own instruments. Check what applies where you work rather than assuming a national answer.

Cross a provincial boundary and the answer inverts. Ontario’s Construction Projects regulation, O. Reg. 213/91, contains no scaffold tagging requirement anywhere in it.

What Ontario requires instead is documentary, and it is triggered by height rather than applying to every scaffold. Where a scaffold exceeds fifteen metres above its base support — or ten metres if it is built from a tube and clamp system — section 130 requires it to be designed by an engineer and erected in accordance with that design. An engineer, or a competent worker designated by the supervisor of the project, must inspect it before it is used to confirm it matches the design drawings and must say so in writing. The constructor keeps the drawings and that written statement at the project for as long as the scaffold stands.

It is worth being clear that the absence of a tag rule in Ontario is a choice rather than an oversight, because the same regulation requires tags elsewhere. A fire extinguisher must carry a tag recording the date of its monthly inspection. An elevating work platform must have a maintenance and inspection record tag attached near the operator’s station. A disconnected power supply must be tagged with the reason, the name of the person who disconnected it, their employer and the date. Ontario knows precisely how to require a tag. For scaffolds, it did not.

British Columbia reaches the same answer by a shorter route. Part 13 of the Occupational Health and Safety Regulation has no tagging provision for scaffolds at all — the word does not appear in the Part. Section 13.3 requires that a work platform and its associated components be inspected before use on each shift and after any modification, with any condition that might endanger workers remedied first. Section 13.13 puts the duty squarely on the employer to ensure scaffolds are in a safe condition and able to withstand the load, regardless of who erected them.

A pre-shift inspection with no required artefact is the loosest regime on this page, and in practice the hardest to evidence once something has gone wrong. Nothing in Part 13 obliges anyone to write anything down.

One caveat, the same one the Australian section carries. Alberta, Ontario and British Columbia are the three provinces read in full for this page. Saskatchewan, Manitoba, Quebec and the Atlantic provinces publish their own instruments and have not been surveyed. Three provinces are not a national answer, and nobody should treat them as one.
