Uneven Sites
An early site visit and inspection by the Event Organiser and his specialist sub-contractor is essential so that site specific factors can be included in the barrier design and Risk Assessment.
Barriers should be placed on flat level surfaces. Where barriers are to be placed on cambered, uneven or sloping surfaces, the system should be checked to ascertain that it can perform as intended. FOS barriers should not be placed on sloping sites, especially where the barrier would be sited ‘upslope’ from the stage.
Due regard requires to be given to the effect of packing on the stability and load capacity of the barrier. Packing up beneath barriers is not recommended and should be avoided, particularly at areas of maximum crowd pressure.
Uneven surfaces should be levelled by placing a suitable fill material in order to provide a flat horizontal bearing surface for the barrier. Where this is not possible the barrier should be moved to a more suitable location.
Construction
Barriers should be properly maintained and constructed. Damaged barrier units should be rejected. Different barrier system components should not be mixed. Adjacent barrier units should be properly connected to form a single continuous barrier. Bespoke barrier units must be used at all changes in direction. Ad-hoc make up infill should not form part of any barrier at any location.
