Scaffolding in confined areas such as lift shafts, staircores, plant rooms, and between closely spaced structures presents unique challenges. Space restrictions limit component handling, access for inspection, and escape routes in an emergency. The scaffold design must account for the restricted dimensions and ensure that safe working platforms can still be achieved. This talk covers the controls for scaffolding in confined and restricted spaces on site.
Key Hazards
Scaffolders struck by components in tight spaces with limited room to manoeuvre
Incomplete edge protection where standard guardrails cannot fit the confined geometry
Restricted escape routes from the scaffold in the event of an emergency
Difficulty inspecting the scaffold due to limited access around the structure
Control Measures
Ensure the scaffold is designed specifically for the confined area by a competent designer.
Use shorter tube lengths and lightweight components where standard lengths cannot be handled safely.
Install edge protection on all accessible sides, using proprietary systems where standard rails will not fit.
Plan and communicate the emergency escape route from every working platform to all scaffold users.
Carry out the pre-erection risk assessment considering manual handling, access, and lighting in the space.
Provide adequate lighting so scaffold inspectors can see all components and connections clearly.
Limit the number of workers on the scaffold at any time to prevent overcrowding in the confined area.
Inspect the scaffold at the required intervals and record findings even where access is difficult.
Brief all operatives on the specific hazards and access restrictions before they use the scaffold.
Remember
Scaffolds in confined areas must be specifically designed by a competent scaffold designer
Use shorter tubes and lightweight components where standard lengths cannot be safely handled
Edge protection must be fitted on all accessible sides using proprietary systems if needed
Plan and communicate the emergency escape route from every platform to all users
Provide adequate lighting so inspectors can clearly see all components and connections
Brief all operatives on the specific hazards and access restrictions before use
