Category: Industrial Scaffolding, Mining
TLDR
Mining scaffolding in South Africa must comply with SANS 10085, the OHS Act 85 of 1993, and the Mine Health and Safety Act 29 of 1996. Surface and underground mining environments present unique hazards, dust, explosive atmosphere zones, confined spaces, and heavy equipment proximity, that demand specialist scaffolding contractors with certified personnel.
Pro Rise Scaffolding, based in Johannesburg, South Africa, provides industrial scaffolding access solutions for mining and minerals processing environments across the country. For plant managers and HSE managers at South African mines, selecting the right scaffolding contractor is a safety-critical decision governed by three interlocking pieces of legislation: SANS 10085, the OHS Act 85 of 1993, and the Mine Health and Safety Act 29 of 1996.
Mining scaffolding in South Africa covers a wide range of access requirements, from surface processing plant maintenance during a scheduled shutdown to shaft headgear inspections, conveyor structure access, and crusher and screen maintenance at concentrators. Each of these environments carries specific hazards that set mining sites apart from standard construction or manufacturing facilities. This guide covers those hazards, the scaffold types that address them, the regulatory framework that governs all scaffold work on South African mines, and the planning process for a mining plant shutdown.

The Unique Challenges of Scaffolding in Mining Environments
Dust and Airborne Particulates
Open-cast and underground mining operations generate high volumes of fine particulate matter. Silica dust at gold and platinum mines, coal dust at collieries, and mineral dust at concentrators all create conditions where scaffold components require more frequent inspection for accelerated corrosion. Dust accumulation on working platforms raises the slip risk on every level, and PPE protocols must account for respiratory hazards alongside fall arrest requirements, two systems that must integrate without conflict.
Heavy Equipment Proximity
Surface processing plants operate heavy crushing, milling, and conveying equipment that generates significant vibration. Vibration affects the integrity of scaffold ties and base plates, requiring shorter inspection cycles than would apply on a static construction site. In active plant areas, scaffold must be designed around the operating envelope of moving equipment, with exclusion zones incorporated into the access plan before a single standard is driven.
Confined Spaces
Mining plants concentrate confined spaces: pressure vessels, silos, mill liners, flotation cells, thickeners, and pipe runs. Any scaffold erected inside or providing access to a confined space triggers the full confined space entry requirements of the OHS Act General Safety Regulations. The scaffolding contractor must supply personnel with valid confined space entry certification, and a standby person and rescue plan must be confirmed before erection begins in any such space.
Shift-Based Operations and Time Pressure
Mines typically operate continuous shift systems. When a processing plant shuts down for maintenance, the clock starts from the moment the last shift clears. Scaffold access must be ready at the start of the maintenance window, and progressive dismantling must keep pace with work completion to allow recommissioning without delay. Contractor personnel logistics, including shift handovers, access gate procedures, and site induction requirements, add lead time that generalist scaffolders routinely underestimate.
Explosive Atmosphere Zones
Certain mining environments, fuel handling areas, reagent storage, and specific underground workings, fall under explosive atmosphere (ATEX) zone classifications. In these zones, non-sparking tools and equipment are mandatory. Standard scaffold strike-plate connections can generate sparks, and scaffold erectors must hold ATEX awareness training in addition to their standard qualifications before entering these areas.
Types of Scaffolding Used in Mining Operations
Surface Processing Plant Maintenance
The surface processing plant, mill buildings, flotation circuits, leach tanks, smelter buildings, and dewatering areas, presents the most varied scaffolding requirement on a mine. Birdcage scaffold inside mill buildings provides full working platforms for reline operations. Independent tied scaffold on the outside of tank structures gives access for corrosion treatment and coating. Modular system scaffold adapts to the irregular geometry of processing equipment without custom steelwork fabrication.

Shaft Headgear and Winder Buildings
Shaft headgear structures at deep-level mines require high-level access for steelwork inspection, painting, and structural maintenance. Headgear structures regularly exceed 50 metres, requiring detailed load calculations with limited tie-back options constrained by the structural geometry of the frame. Cantilever scaffold and hanging scaffold systems address access points where conventional base-supported structures cannot reach.
Conveyor and Materials Handling Structures
Conveyor galleries and transfer towers at surface mines run for hundreds of metres and require access for routine inspections of idlers, pulleys, and belt tracking systems. Scaffold access for conveyor maintenance must integrate with the conveyor's operating schedule, in many cases, sections remain operational while adjacent sections undergo maintenance. The access system must physically separate the working area from the live conveyor run.
Crusher and Screen Access
Primary and secondary crusher installations are among the most physically confined and mechanically hazardous structures on a mining surface plant. Crusher maintenance requires access to the mantle and concave, the toggle plate, and the hydraulic cylinders in confined spaces directly below the feed opening. Scaffold in a crusher chamber must account for the risk of falling material from the feed chute if isolation of the feed system is incomplete, and the erection sequence must progress from the outside inward to maintain a safe egress route at every stage.
Concentrator Maintenance
Concentrators contain multiple high-level access points: flotation cell froth launders, agitator drives, thickener rakes, and autoclave pressure vessels. For a detailed overview of refinery and concentrator scaffolding and how complex access planning is managed in process plant environments, see Pro Rise Scaffolding's refinery service page.
The Regulatory Framework for Mining Scaffolding in South Africa
Three instruments govern scaffolding on South African mining sites.
SANS 10085: The Code of Practice
SANS 10085 is the South African national standard for the design, erection, inspection, use, modification, and dismantling of steel tube and coupler scaffold and prefabricated modular scaffold. The 2024 edition (SANS 10085-1:2024) updates load classifications and explicitly prohibits the use of trestle ("bokkie") and non-compliant frame scaffold types that remain common among generalist contractors.
All scaffold must be inspected by a competent person before first use, after adverse weather, after any modification, and at intervals not exceeding seven days during use. SANS 10085 also specifies a colour-coded tagging system: green (safe to use), red (unsafe, do not use), and yellow (under construction or modification). Any scaffold structure without a current tag is non-compliant, and the principal employer carries legal liability for any incident on an untagged structure.
OHS Act 85 of 1993 and Construction Regulations
The Occupational Health and Safety Act 85 of 1993, together with the Construction Regulations of 2014, sets out the legal duties of employer and contractor for all scaffolding work. Section 16 of the Construction Regulations requires a written appointment of a competent person to supervise all scaffold operations. The employer bears direct legal liability if scaffold erected on their premises does not comply with these regulations.

Mine Health and Safety Act 29 of 1996
Where a scaffolding contractor operates on a mine, including surface workings and processing plants, the Mine Health and Safety Act 29 of 1996 (MHSA) governs principal hazard management. The mine's Health and Safety Committee must approve the risk assessment for scaffold operations before work starts. Under the MHSA, the mine employer carries ultimate accountability for the safety of all contractors on site.
A section 54 instruction issued by a DMRE (Department of Mineral Resources and Energy) inspector can result in an immediate work stoppage across the entire mine, including all ongoing scaffold erections. Scaffolding contractors working on mines must maintain a safety management system that aligns with the mine's principal hazard management plan, particularly for fall protection and confined space entry.
Qualifications Required for Scaffolders in Mining Environments
Scaffolders on South African mining sites require the following as a minimum:
- Scaffold competency certificate: Covering erection, modification, and dismantling of the scaffold system type in use, issued by an accredited training provider
- Working at heights (WAH): SAQA unit standard 120362 (NQF Level 3), a prerequisite for any work on scaffold platforms above 2 metres
- Confined space entry certificate: Required for any scaffold erected in or providing access to a confined space as defined by the OHS Act General Safety Regulations
- Mine site induction: Each mine requires its own contractor induction before any personnel may enter the property
- ATEX awareness training: Required for personnel working in designated explosive atmosphere zones
Pro Rise Scaffolding has worked across mining and minerals processing environments in South Africa, with all site personnel holding the high-risk work and confined space qualifications required in these environments. This means no delays at the access gate while personnel clear induction backlogs, and no exposure of the client to liability from unqualified workers on a regulated mining property.
Planning Scaffolding Access for a Mining Plant Shutdown
A mining plant shutdown is a time-compressed, high-activity event. Scaffolding access planning for a shutdown follows five phases.
1. Access Priority Mapping
Before the shutdown begins, the scaffolding contractor maps all access requirements against the maintenance scope of work. Critical path items, the tasks that directly determine when the plant returns to production, receive priority scaffold erection slots. Non-critical access is scheduled around them to avoid congestion and resource conflicts.
2. Pre-Fabrication and Yard Preparation
All scaffold components for the shutdown should be on site and verified before the plant goes offline. Counting, sorting, and pre-staging scaffold materials in a designated laydown area eliminates the downtime that incomplete deliveries create once the maintenance window has opened.
3. Progressive Erection
Scaffold teams work through the plant in a sequence that matches the maintenance crew's programme. A scaffold structure erected and standing idle for days before maintenance starts is a resource waste. Progressive erection, building what is needed, when it is needed, keeps the critical path moving and reduces the total scaffold inventory required on site at any one time.
4. Personnel Logistics
On large shutdowns, multiple scaffold gangs operate simultaneously across different sections of the plant. Each gang requires a qualified team leader with authority to issue and clear the scaffold tag. Shift handover documentation ensures continuity between day and night crews and maintains a single, accurate record of scaffold status across the plant.
5. Dismantling and Site Clearance
As maintenance work completes section by section, scaffold must be removed before pre-commissioning checks can proceed. Scaffold left in place during equipment reinstatement and pre-commissioning creates interference and delays startup. A disciplined dismantling schedule, coordinated with the maintenance supervisor, prevents these delays.
For planned shutdown maintenance scaffolding support across South African mining and processing plants, Pro Rise Scaffolding provides full scoping, planning, and execution services.
Frequently Asked Questions
Q: What legislation governs scaffolding on South African mining sites?
Three instruments apply: SANS 10085 (the code of practice for scaffold design, erection, and inspection), the OHS Act 85 of 1993 and Construction Regulations 2014 (which set out employer and contractor duties), and the Mine Health and Safety Act 29 of 1996, which governs all work conducted on mine properties including surface processing plants. Where the MHSA and OHS Act create conflicting obligations on a mine property, the MHSA takes precedence.
Q: Do scaffolders on mining sites need different qualifications than those on construction sites?
Yes. In addition to a scaffold competency certificate, mining site scaffolders require working at heights (WAH) certification to SAQA unit standard 120362, confined space entry certification for any work in enclosed spaces, and must complete each mine's own site induction before starting work. In designated explosive atmosphere zones, ATEX awareness training is also required.
Q: What scaffold systems work best for processing plant maintenance in South Africa?
Modular system scaffold, such as ringlock or cuplock, is the preferred system for surface processing plant maintenance. Its adaptability to irregular plant geometry, higher working load capacity, and faster erection and dismantling times make it more suitable for mining environments than traditional tube-and-coupler systems. The speed advantage directly reduces labour time on the critical path during a plant shutdown.
Q: How does the Mine Health and Safety Act affect scaffold contractors on site?
Under the MHSA, the mine employer is the principal employer responsible for the health and safety of all contractors on the property. The scaffold contractor must submit a risk assessment to the mine's Health and Safety Committee before work begins. A DMRE inspector can issue a section 54 instruction that stops all work across the mine, including active scaffold erections, if unsafe conditions are found. Contractors must maintain their own MHSA-aligned safety management system to avoid triggering a stoppage.
Q: What is the SANS 10085 scaffold tagging system?
SANS 10085 requires every scaffold structure to carry a colour-coded tag: green (safe to use), red (unsafe, do not use), or yellow (under construction or modification). Tags must be updated by a competent person after every formal inspection. Scaffold without a current tag is non-compliant, and the client bears legal liability as principal employer for any incident on an untagged structure.
Q: How far in advance should a mine engage a scaffolding contractor for a planned shutdown?
Four to six weeks before the shutdown date is a practical minimum for a complex mining plant shutdown. This allows time for access priority mapping, pre-fabrication of specialised scaffold configurations, personnel logistics planning, and the submission of risk assessments to the mine's Health and Safety Committee. Shorter lead times are possible for smaller scopes, but compress the planning time that protects the maintenance critical path.
Q: Why use a specialist industrial scaffolding contractor rather than a general contractor on a mine?
Mining environments present hazards, confined spaces, explosive atmospheres, heavy equipment proximity, and vibration, that generalist building scaffold contractors are not trained to manage. A specialist industrial contractor brings site-specific risk assessments, fully qualified personnel, and proven procedures for operating on MHSA-regulated properties. The cost of a section 54 stoppage or a reportable workplace incident far exceeds any short-term saving from appointing an unqualified contractor.
