Scaffold Tag System Log

The Scaffold Tag System Log tracks the status of all scaffolds on site using a colour-coded tag system indicating whether a scaffold is safe to use (green), requires inspection (amber), or is unsafe and must not be used (red). It records tag changes, inspection dates, and the competent person responsible. The system provides an immediate visual indication of scaffold status to all site users.

1. Scaffold Tags — Inspection Status at a Glance

The scaffold tag system solves a critical information problem: how does a trade worker approaching a scaffold know whether it has been inspected and is safe to use? The tag at the access point provides the answer — green means safe, red means stay out. It is both a communication tool and a compliance tool.

The tag system operates at two levels: the tag at the scaffold (visible to workers) and the tag system log (visible to management). A weekly check of the log gives a complete picture of compliance, identifying structures approaching their due date for re-inspection.

The scaffold tag log is the management overview — tags are the field communication

The log records every structure on site, tag status, inspection dates, and next due date. The tag at the scaffold provides immediate worker communication. Both levels are needed for a functioning system.

2. Scaffold Tag System Log — What to Record

Field	Content
Scaffold reference	Unique reference for each structure on site.
Location	Description (e.g. 'North elevation — Blocks A–C').
Erection date	Date scaffold erected.
Handover cert	Handover certificate issued by scaffolding contractor. Date.
Tag status	Current tag: Green / Amber (restrictions) / Red.
Last inspection	Date of last inspection. Inspector name. Record ref.
Next inspection due	Date by which next inspection must be completed.
Restrictions	Any restrictions in force (loading class, access areas).
Defects open	Open defects — description, action required, responsible, deadline.
Tag removed/dismantled	Date dismantled. Final status.

3. Common Mistakes

Scaffold left with green tag after 7-day period expired

The green tag must have a visible 'next inspection due' date. When that date passes without a new inspection, the tag misleadingly shows safe. The log must flag upcoming expiry. On the expiry day, the tag must be changed to Red until a new inspection is completed.

Only one tag at main access — no tags at secondary points

Large scaffolds with multiple access points need tags at each point. If this is impractical, prominent 'refer to site manager' signage must be placed at secondary points so workers do not access untagged entry points without verification.

Red tag removed by trade worker

The red tag must be in a location and format that makes unauthorised removal visible. Ideally it should be tagged to the ladder gate. Any worker found accessing a red-tagged scaffold must be challenged and the incident recorded.

Tag log not updated when scaffold modified

Any modification — adding bays, removing ties, changing loading — must trigger a review. The modified scaffold must be re-inspected before being tagged green again. The log must record every modification.

No system for managing during partial demobilisation

Partial scaffold structures that no longer comply with the original design must be re-assessed. The tag system must reflect the current configuration, not the original design that is no longer in place.

4. Frequently Asked Questions

Who can change a tag from Red to Green?▾

Only a competent person who has conducted a scaffold inspection. The inspection must be completed first — the tag change is the last step. A site manager, subcontractor, or trade worker cannot change the tag without conducting a competent inspection.

Is a scaffold tag system a legal requirement?▾

The Work at Height Regulations Schedule 7 requires that inspection results are available to persons using the scaffold. The tag system is the industry-standard practical mechanism for meeting this requirement. It is not mandated by name, but it is the standard method for meeting the availability requirement.

How is the tag system managed in wet or outdoor conditions?▾

Tags must be weather resistant — laminated or made from durable materials. Standard paper tags in unprotected holders are inadequate. Suppliers such as Good to Go Safety provide weather-resistant systems. Tags must remain legible throughout the inspection period.

What happens when a scaffold contractor changes?▾

The incoming contractor must inspect and issue their own handover certificate and initial tag before trades use the scaffold. The outgoing contractor's records are retained, but the incoming contractor cannot inherit the previous inspection without conducting their own assessment.
