You do not automatically need a harness simply because you are working on scaffolding. On a properly erected working platform with suitable guardrails and safe access, the scaffold provides collective fall protection. A harness may be required when the planned work leaves a person exposed to a fall and that risk cannot be adequately controlled by collective protection.
The decision must come from an assessment of the task, the scaffold and the method of work. Wearing a harness without a suitable attachment point does not make an unsafe platform safe.
When might a harness be needed?
Scaffolders can be exposed to unprotected edges while erecting, altering or dismantling a structure. Their work must follow a planned method that establishes collective protection as early as practicable and controls any remaining exposure. Where that method calls for personal fall protection, workers need the correct harness, connection equipment and suitable anchorage.
A harness may also form part of the safe system for suspended scaffolding. The requirements depend on the equipment and its instructions. Workers must be trained in the arrangement provided, including where and how to connect.
Other tasks may require personal protection if a worker must operate outside a fully protected area. That is not permission to step past a guardrail and clip onto the nearest tube. The work must be planned, the attachment point assessed and the risks of a fall considered before anyone proceeds.
Do you need a harness when guardrails are fitted?
For general work on a complete scaffold platform with suitable guardrails and safe access, a harness is not routinely required. Effective edge protection safeguards everyone using the platform without relying on each person to clip on correctly.
Guardrails help prevent people falling, while the purpose of toe boards is to help stop tools and materials falling from the platform edge. Both need to be considered when the scaffold is planned.
Check that the platform is suitable for the intended work and that its protection has not been removed or altered. If a board or guardrail is missing, stop using the affected area and report it. Regular scaffold inspections help identify changes that could affect safe use, but workers should report a problem as soon as they notice it.
A site’s working procedure may call for additional protection for a particular task. Workers should follow the assessed method rather than assume that every platform has identical requirements.
Is there a height at which a harness becomes compulsory?
UK work-at-height rules do not set a universal height at which everyone on a scaffold must put on a harness. They apply where a fall could cause personal injury, including at relatively low heights.
Figures quoted for other countries should not be used as a UK harness rule. What matters is whether a fall is possible, how the work is carried out and which precautions will control the risk.
The order of consideration is to avoid work at height where reasonably practicable, prevent a fall where work at height is necessary, and minimise the consequences if a fall risk remains. Measures that protect everyone, such as suitable working platforms and guardrails, take priority over equipment that protects only the wearer.
How should a harness be attached?
A fall-protection system needs more than a full-body harness. The lanyard or other connection must suit the task, and its anchor point must be identified as suitable for the forces it could experience.
Do not assume that a guardrail or an arbitrary scaffold tube is an approved anchor. The permitted attachment points and method should be established by competent people as part of the work plan.
The position of an anchor also matters. A long lanyard attached too low may leave insufficient space to stop a fall before the worker strikes the ground or another part of the structure. The complete system needs to be assessed together.
What checks are needed before use?
A worker should check the harness and connection equipment before use. Look for damaged stitching, cuts, abrasion, contamination, distorted metalwork and connectors that do not operate correctly. Equipment with a defect should be taken out of use and reported.
Pre-use checks do not replace the more detailed inspections required under the employer’s equipment inspection arrangements. Workers also need instruction in fitting the harness, connecting it correctly and understanding the limits of the system.
There must be a rescue plan before work starts. A fall-arrest system may stop a person reaching the ground while leaving them suspended and needing prompt help. The plan must identify how that person will be reached and rescued.
Who decides whether a harness is required?
The people planning and controlling the work must assess the fall risk and specify a safe method. Scaffolders erecting the structure, contractors using it and those operating specialist access equipment can face different hazards, even on the same project.
Before starting, workers should know whether the platform is ready for use, which areas are protected, whether personal fall protection is required for their task and where an approved connection can be made. This applies to local work such as scaffolding in Epping as it does to any other site. If those points are unclear, the work should pause until they are resolved.
A harness is an important safeguard when it forms part of a properly planned system. For ordinary work on a complete scaffold, the priority is a suitable platform with effective collective protection.
