scope:

This standard prescribes rules and establishes minimum safety requirements for the protection of employees and invitees 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/ASSP A10.8, Scaffolding Safety Requirements).

This standard does not apply to trenches and trench covers (see ANSI/ASSP A10.12, Safety Requirements of Excavation).

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

This standard does not apply to roofing work on low-sloped roofs (see ANSI/ASSP 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 invitees from falls through temporary roof and floor holes, wall openings, stairways, inactive leading edges, and other unprotected edges.
