1. The Legal Mandate: Construction Regulation 16(1) & SANS 10085
Access scaffolding is a temporary structural engineering system carrying human lives, heavy construction machinery, brick pallets, and high-voltage tools tens of metres above the ground. If a base jack slips off a sole board, a coupler shears under load, or diagonal bracing is removed to fit a pipe, the structure will buckle under self-weight or wind pressure.
Under Construction Regulation 16(1) (CR 16) of the Occupational Health and Safety Act (Act 85 of 1993), the employer must appoint a competent person in writing to ensure that all scaffolding work is executed in accordance with SANS 10085-1 (The Design, Erection, Use and Inspection of Access Scaffolding).
The law makes a critical distinction: general artisans or safety officers cannot legally sign off scaffolding unless they hold formal, accredited Scaffolding Inspector Certification. Enrolling candidates in accredited Scaffolding Inspector Training ensures structural integrity and eliminates corporate legal exposure.

2. Defining Competence: SAQA Unit Standard 263205 Curriculum
To satisfy the statutory definition of 'competence' under the OHS Act, an appointed Scaffold Inspector must have completed accredited training aligned with SAQA Unit Standard 263205 (Inspect Access Scaffolding).
The curriculum covers: Structural Mechanics & Load Classes (Light Duty 0.75 kN/m2, Medium Duty 1.5 kN/m2, Heavy Duty 3.0 kN/m2, Special Duty); Ground Bearing Capacity (calculating soft soil load spreading using timber sole boards); Component Quality Verification (detecting internal tube corrosion, dented standards, bent spigots, and worn coupler threads); Bracing Geometry (plan bracing, dog-leg facade bracing); and Legal Tagging Systems.
SANS 10085 Scaffolding Duty Classes & Loading Limits
| Duty Classification | Maximum Permissible Load | Platform Width & Board Count | Authorized Workplace Activities |
|---|---|---|---|
| Inspection / Very Light Duty | 0.75 kN/m² (75 kg per m²) | Minimum 3 boards (675 mm wide) | Access only, visual inspections, light painting with zero material storage. |
| Light Duty | 1.50 kN/m² (150 kg per m²) | Minimum 4 boards (900 mm wide) | Plastering, electrical cable installation, glazing, lightweight hand tools. |
| Medium Duty (General Building) | 2.25 kN/m² (225 kg per m²) | Minimum 5 boards (1 125 mm wide) | Bricklaying, concrete patching, stacking limited brick pallets (evenly spread). |
| Heavy Duty (Masonry / Steel) | 3.00 kN/m² (300 kg per m²) | Minimum 5 to 6 boards (1 125 - 1 350 mm) | Heavy stone masonry, structural steel fabrication, heavy demolition debris. |
3. SANS 10085 Critical Engineering Inspection Points Explained
An appointed inspector conducts a methodical structural audit from the ground foundation upward:
1. Foundations & Base Jacks: Verifies sole boards span at least two standards; base jacks are plumb with thread extensions strictly under 300mm.
2. Standards & Ledgers: Verifies vertical standards are within 1:500 plumb tolerance; ledgers and transoms are secured with right-angle double couplers torqued to 50 Nm.
3. Bracing & Tie-Ins: Verifies diagonal facade bracing is installed on at least every fifth bay from ground to top, and positive mechanical building ties are anchored at 3:1 height ratios.
4. Decking & Edge Protection: Verifies platforms are close-boarded (<25mm gap), trapdoor hatches are operational, 900-1000mm top guardrails, 450mm mid-rails, and 150mm toe-boards are fully secured.
4. The Scafftag System & The Inspector's Absolute Authority to Condemn
The appointed Scaffold Inspector possesses absolute statutory authority over the Scafftag System.
If the inspector discovers an unauthorized modification (such as a subcontractor removing toe-boards or unbolting a wall tie), the inspector immediately removes the Green card, inserts the Red 'DO NOT USE' Tag, and records the violation in the master inspection register. Work on that scaffold stops immediately. No project manager or site director has the legal authority to overrule an inspector's red tag.
5. 5-Stage Comprehensive Scaffolding Inspection Methodology
Check soil compaction, drainage channels, sole board placement, and verify adjustable base jack threads are under 300mm.
Use magnetic spirit level to check vertical standard plumbness and use a calibrated torque spanner to test 50 Nm coupler tightness.
Verify continuous diagonal facade bracing and verify mechanical through-bolt or ring-anchor ties into the permanent building.
Confirm zero platform plank gaps, verify internal ladder access with functioning spring trapdoors, and inspect double guardrails.
Insert signed Green Scafftag at the ladder entry, complete the 7-day inspection register in the site safety file, and hand over to the site manager.
