Overview
This European Standard specifies product requirements, methods of structural and general design and tests for protection fans for scaffolds to protect workers as well as members of public from objects that may fall off the outside edge of scaffolds being used close to where they are working or passing by. Because these protection fans are required to arrest the fall of substantial objects such as bricks, blocks, scaffold boards and the like, they could be considered as a necessary safety-critical accessory for scaffolds. This, coupled with the fact that they have to arrest the fall of significant objects, that is subjected to significant dynamic loads, puts them in the category of complex structures. The responsible committee is NA 005-11-05 AA "Arbeits- und Schutzgerüste (Spiegelausschuss zu CEN/TC 53/WG 1 bis 4, WG 10, WG 13 und WG 14") ("Service and working scaffolds and scaffolding components (national mirror committee for CEN/TC 53/WG 1 to WG 3, WG 10, WG 3 and WG 14)") at DIN.
