Members of the Scaffolding, Shoring and Forming Institute (SSFI), which include designers and manufacturers of scaffolding, shoring, and forming products, note that they are aware of the increased use of scaffolds as fall arrest anchorages. The members recognize that scaffold erectors and users are being required to use Personal Fall Arrest Systems (PFAS) in some jurisdictions.
Scaffold components may seem to be a convenient anchorage, and in many situations, scaffold components are the only readily available components for use as a fall arrest anchorage. However, many scaffold systems and components were not designed or manufactured specifically to withstand fall arrest forces. These forces are quite substantial, and personal fall arrest systems impose dynamic loads on anchorages. SSFI cautions users and erectors that not all scaffold components and systems are designed for the purpose of providing an adequate fall arrest anchorage.
PFAS should, if possible, be attached to a permanent structure. If a permanent structure is not available, the scaffold component may be used as a PFAS anchorage PROVIDED the manufacturer has determined such use to be feasible and safe through design and testing. In this case, it is essential that the manufacturer's instructions are followed exactly.
Design and testing of scaffold components used as a PFAS anchorage must comply with the fall arrest standards that apply in the jurisdiction in which the scaffold is being used.
