This Standard establishes safety requirements for powered platforms (scaffolds) for buildings where window cleaning and related services are accomplished by means of suspended equipment at heights in excess of 35 ft (11 m) above a safe surface (e.g., grade, street, floor,or roof level). Additionally, this Standard establishes safety requirements for permanent traveling ladders and gantries (TLG).

It pertains to either permanently installed or transportable equipment meeting the requirements of this Standard.

Powered platforms and TLGs may be used or operated by one or more persons engaged in services such as normal building maintenance. The equipment may also be used for tasks such as caulking, metal polishing, reglazing, or other building repairs.

This Standard does not apply to other suspended powered platforms used for remedial renovations or

modifications to buildings. The safe use of these scaffolds is included in ANSI A10.8-2001, Safety Requirements for

Scaffolding. This Standard does not relate to any service performed by persons supported by equipment covered by any of the ANSI A92 standards.
