A safety apparatus capable of installation around the top level of a scaffolding from one scaffolding level below includes a plurality of support posts and rails. The support posts each have a set of hooks for pivotably attaching rails, and are each capable of attachment to a scaffolding by workers at a lower level so that a portion of the support post extends above the scaffolding's top level work surface. Apparatus installation entails pivotably attaching rails to a first support post, which is raised to the edge of the scaffolding and attached. A second support post is then pivotably attached to the free ends of the rails and similarly raised and attached to form a barrier along one edge of the scaffolding. Auxiliary rails may be pivotably attached to an installed support post from the lower level, and the free ends of these auxiliary rails may be pivotably attached to a third support post, which may then be raised and attached to form an adjacent safety barrier. A final barrier may be erected by way of a finishing post, which may be used to attach auxiliary rails to a previously installed support post. An advantage of the apparatus is that no workers are required to be present atop an unsafe top level of a scaffolding while safety barriers are being installed.
