Aberdeen City CouncilAppendix 13.2 Hierarchy of protective measures (Scaffold Erection and Falling Objects)Risk assessmentA suitable and sufficient risk assessment must be undertaken before working at height todetermine what health and safety measures are required. After determining whether or notthe work can be done in a different way, e.g. from a mobile elevating work platform (MEWP)or 'scissor lift', you should seek to: eliminate the hazard, reduce the risk, provide informationand introduce control measures.You should consider: the activity, the equipment to be used, the location, e.g. near or overroads, under power lines, etc., the environment, e.g. weather, temperature, lighting, theduration of the work, and the condition and stability of the work surfaces.In deciding what to do, you should adopt a hierarchical approach (see table 3.2). Wherepossible, eliminate the hazard. Where a risk remains, then steps should be planned andimplemented in order to reduce or control that risk. The table gives examples of protectivemeasures, which may be used in isolation or together.Contact should be made with the Street Occupations Unit for permission and advice forerectors to adopt a procedure or system that utilises advance guardrails.Scaffold PlanA good Scaffold Plan (sometimes referred to as a method statement) will be clear andconcise, and laid out following the guidance contained in Section 3.5, Scaffold Plan. It willidentify the hazards, assess the risk and specify the precautions to be taken.A plan should also cover labour levels, tools and equipment to be used as well as whathappens when work needs to be modified, e.g. review arrangements (perhaps by asupervisor, engineer, site agent, etc.). It should, where possible, be self-contained but maycross reference other documentation, e.g. drawings and specifications, risk assessments,permits. This is to avoid repetition. Sketches are a useful way of disseminating information.Page 19 of 46 Issue 1
Aberdeen City CouncilTable 3.2 Hierarchy approachEliminateReduceIssue Protective Measure(s) NotesThe following are examples of measures that may be used to prevent the risk of members ofthe public being hit by falling objects.Roadclosure(s)Apply for and implement a road closure.Do not assume that a roadclosure will not be granted.Apply for and implement a partial roadclosure.The following are examples of measures that may be used to reduce exposureto the risk of members of the public being hit by falling objects.'Off peak'workingSheeting,Netting andFansConsider whether unloading / loading cantake place ‘off peak’.Undertake any erection and/ordismantling during hours where there arefewer members of the public, i.e. 'offpeak' working.Sheeting/netting should be used toenclose scaffolding on its public side toprevent loose materials from falling on tomembers of the public.Note that if sheeting or netting issubsequently introduced it may have adesign implication requiring scaffoldmodifications.Work during 'off peak' night timehours of darkness will need totake account of the hazarddarknessThese measures are particularlyimportant where the scaffoldingfronts on to a public accessway.The scaffold supporting anysheeting, netting or fan(s) mustbe able to support anyadditional load(s).InformTunnelsFans should be erected on the scaffold tosupplement the sheeting. Considerwhether these should be progressive, upthe height of the structure.During quiet hours, erect a protective'tunnel' (and/or fan(s)) to protectmembers of the public during anyerection ongoing.Where work is carried out closeto pedestrian or vehicularaccess, scaffolds that aresheeted down to hoarding levelcan minimise both the risk tothe public and the area lost topublic access.The following are examples of the planning and information that should be provided whenworking in areas where members of the public can be hit by falling objects.PlanningInductionUndertake and disseminate a riskassessment and scaffold plan (methodstatement)Brief workers on site-specific issues, e.g.hazards, restrictions, etc.Ensure that workers understandwhat they have to do, when andwhere.ControlThe following are examples of control measures that may be implemented to reduce furtherthe risk of being hit by falling objects.Page 20 of 46 Issue 1
