5.3 Scaffold Inspection, Tagging Systems and Records
Key Takeaways
DOSH's work-at-height guidance says equipment whose safety depends on its installation, such as scaffolding, must be inspected by a person with sufficient skills, knowledge and experience before use, at suitable intervals and after adverse events, with records kept.
The repealed BOWEC regulation 85 barred use of a scaffold not inspected by a designated person within the preceding seven days or after weather likely to affect its stability, with results entered in a register.
A green scaffold tag means the scaffold has been inspected and is safe for use within its stated load; a red tag or an empty tag holder means do not use.
The collapse of a scaffold more than 5 metres high is a dangerous occurrence that must be notified to DOSH under NADOPOD 2004, even if no one is injured.
DOSH's falls guideline says scaffold access ladders must be set at 1:4, secured top and bottom, with stiles extending 1 metre above the step-off point.
The inspection duty today
The BOWEC rule that many SSS candidates still quote was regulation 85. A scaffold could not be used unless it had been inspected by a designated person within the preceding seven days, and again after weather likely to affect its strength or stability. The results went into a register on site. The seven-day rule did not apply to scaffolds erected within the past seven days, to trestle scaffolds, or to scaffolds from which no one could fall more than 3 m. BOWEC was repealed on 1 June 2024.
The current duties come from:
- OSHA 1994 section 15(2)(a) (safe plant) and CDM 2024 regulation 21 (temporary structures maintained for foreseeable loads and used as designed)
- DOSH's work-at-height guidance, which says that where the safety of equipment such as scaffolding depends on how it is installed, it must not be used before it is inspected by a person with sufficient skills, knowledge and experience (SKE). Inspections should be repeated at suitable intervals depending on the environment and use, for example after bad weather or accidental damage, and records must be kept.
- DOSH's falls guideline, which says that if instability or damage is found, the scaffold should not be used until a certificated scaffolder has repaired it
Recommended site rule: inspect every scaffold
- before first use
- at intervals of no more than seven days while in use
- after any alteration
- after bad weather, impact or other damage
- after a long stoppage, such as a festive shutdown
This mirrors the former BOWEC regulation 85 and the UK Work at Height Regulations 2005, which DOSH's work-at-height page cites.
Who inspects
The inspector must be competent for the scaffold type: a person with the SKE to recognise defects, typically:
- a registered scaffolder of the appropriate class
- a scaffold supervisor or inspector appointed by the scaffolding contractor
- for designed scaffolds, someone who can check the scaffold against the drawings
The SSS audits these inspections and carries out independent checks. The SSS should not sign a scaffold as safe unless competent in that scaffold type.
The inspection checklist
| Area | What to check |
|---|---|
| Ground and foundations | Firm, drained ground; no washout or settlement; sole boards and base plates in place; base jacks within their extension limit; nothing excavated nearby that could undermine the scaffold |
| Standards, ledgers, transoms | Plumb and level; correct spacing; joints staggered; no damaged or bent tubes |
| Couplers and fittings | Correct coupler type in each position (right-angle couplers on load-bearing joints); tightened to the manufacturer's specification; no cracked or corroded fittings; system locks engaged |
| Bracing | Façade and ledger bracing complete as designed; none removed |
| Ties | All ties present at the design spacing and secure; none removed by other trades; extra ties where the scaffold is sheeted or netted |
| Platforms | Fully boarded; boards sound, secured and correctly supported with proper overhang; no gaps or trip steps; platform width suitable |
| Edge protection | Guardrails 0.9–1.1 m with midrail and toe-board on all open sides (DOSH 4.2); brick guards where materials are stacked |
| Access | Ladders at 1:4, secured top and bottom, stiles 1 m above the step-off point (DOSH 4.3); stair towers complete; trapdoors closed |
| Loading | No overloading; materials only on designed bays; load class shown on the tag |
| Protection of others | Fans, nets or sheeting intact; exclusion zones below where needed |
| Special items | Hoist, sheeting or loading bay to their own design; no unauthorised attachments |
Tagging systems
A tag system tells every user, at the point of access, whether the scaffold may be used. Most Malaysian sites use a proprietary or company scaffold tag with a holder fixed at every access point.
| Status | Typical meaning | Who may go on the scaffold |
|---|---|---|
| Green: safe for use | Inspected and complete; shows the inspection date, the next inspection due, the load class and the inspector's name | All trained users, within the stated load |
| Red: do not use, or an empty holder | Under erection, alteration or dismantling; failed inspection; inspection overdue; damaged | Only scaffolders working on it, under their own controls |
| Yellow (in some systems) | Restricted use under conditions written on the tag, for example "harness required, guardrail removed bay 3" | Only the people and tasks named on the tag |
Rules that make tagging work:
- Default to "do not use". Holders are printed so that an empty holder means "do not use". Removing a green insert takes the scaffold out of use.
- Tags expire. The tag shows the date of the next inspection. An out-of-date green tag is treated as red.
- Define colours in the site rules. Yellow-tag meanings differ between systems. Write the meaning into the construction phase plan's site rules and the induction.
- The tag does not replace the register. Keep the inspection record, the defects found, the actions taken and the sign-off.
Records
Keep a scaffold register or inspection log for each scaffold, with:
- an identification number and location
- the scaffold type and design reference (drawing or system configuration)
- the load class
- the date, time and result of each inspection
- defects found, the action required, who must act and by when
- verification that defects were rectified
- the inspector's name, signature and competency
Keep it on site and show it to DOSH officers on request. It is also the evidence that the duties under sections 15 and 18A of OSHA were met.
When things go wrong
If a scaffold more than 5 m high collapses, or partly collapses so that a substantial part falls or overturns, this is a dangerous occurrence under item 1 of Part I of the NADOPOD Second Schedule. Notify the nearest DOSH office immediately and send the written report within seven days, whether or not anyone was hurt. Preserve the scene under regulation 9.
Scenario: Monday after the storm
Over the weekend, 120 mm of rain fell and strong gusts struck the site. On Monday morning the SSS finds:
- the subgrade washed out under four sole boards
- two transoms and several boards displaced on the sixth lift
- green tags that expired on Sunday
Response:
- Withdraw the scaffold from use: remove the green inserts so the holders show "do not use", add red tags and barricade the ladder bases. Brief the trades at the toolbox meeting.
- The scaffolding contractor's competent scaffolders prop the bays, reinstate and compact the ground, replace the sole boards, and re-fix the transoms and boards.
- A competent inspector carries out a full inspection, records the defects and repairs in the register, and issues new green tags with the next inspection date.
- The SSS notes the event as a near miss and reviews the drainage near scaffold foundations.
What did the repealed BOWEC regulation 85 require for scaffold inspection?
Inspection within the previous 7 days and after bad weather, with a register
Inspection once a year by a DOSH officer before continued use
Inspection only after a collapse, before the scaffold is rebuilt
Inspection only for scaffolds over 40 m high, by a registered Professional Engineer
A scaffold's tag holder at the access ladder is empty. How should workers treat the scaffold?
As safe, because a missing tag usually only means the paperwork is late
As not to be used until it is inspected and a valid tag is issued
As safe for light work only
As safe if the foreman gives verbal permission
Under a typical scaffold tag system, a green tag at the access point shows a next-inspection date that passed two days ago. How should the scaffold be treated?
As safe, because a green tag stays valid until someone removes it
As safe for light work only, until the end of the week
As red-tagged: do not use until it is re-inspected and re-tagged
As safe if the scaffold looks unchanged since the last inspection
