This standard prescribes rules and establishes minimum safety requirements for the protection of employees and the public from hazards arising out of or associated with temporary roof and floor holes, wall openings, stairways, and other unprotected sides and edges, roofs, during construction and demolition activities. This standard applies only to those instances when the leading edge work is inactive and is not currently under construction and is, therefore, considered an unprotected side and edge.

This standard does not apply to scaffolds or scaffold stairs used as temporary access (see ANSI/ASSE A10.8, Scaffolding Safety Requirements).

This standard does not apply to steel erection (see ANSI/ASSE A10.13, Safety Requirements for Steel Erection).

This standard does not apply to the application of membrane roofing materials. See ANSI/ASSE A10.24, Roofing – Safety Requirements for Low-Sloped Roofs for membrane roofing operations on low-sloped roofs.

Purpose. The purpose of this standard is to establish reasonable and practical safety requirements to protect employees and the public from falls through temporary roof and floor holes, wall openings, stairways, active and inactive leading edges and other unprotected edges.
