ASME A120.1:2006 pdf free download Safety Requirements for Powered Platforms and Traveling Ladders and Gantries for Building Maintenance
1.1 Scope
This Standard establishes safety requirements forpowered platforms (scaffolds) for buildings wherewindow cleaning and related services are accomplishedby means of suspended equipment at heights in excess of35 ft (11 m) above a safe surface (e.g.,grade, street, floor,or roof level).Additionally, this Standard establishessafety requirements for permanent traveling laddersand gantries (TLG).
It pertains to either permanently installed or transpor-table equipment meeting the requirements of this Stan-dard.
Powered platforms and TLGs may be used or operatedby one or more persons engaged in services such asnormal building maintenance.The equipment may alsobe used for tasks such as caulking, metal polishing,reglazing, or other building repairs.
This Standard does not apply to other suspendedpowered platforms used for remedial renovations ormodifications to buildings. The safe use of these scaffoldsis included in ANSI A10.8-2001, Safety Requirements forScaffolding.
This Standard does not relate to any service performedby persons supported by equipment covered by any of theANSI A92 standards.
1.2 Purpose
The purpose of this Standard is to ensure the protectionof powered-platform users and traveling ladder andgantry users, and persons exposed to equipment usedwith the previously described maintenance of buildings.It is also intended for use by architects, engineers,designers,manufacturers,inspectors, purchasers,building owners, and others associated with the installa-tion of powered platforms and traveling ladders andgantries.
Additionally, it is recommended for use by enforcementagencies having jurisdiction over the installation ofpowered platforms and traveling ladders and gantriesto ensure that the platforms meet the safety provisionsof this Standard.
1.3 Application of This Standard
1.3.1 ð21Þ Applications. This Standard applies to the instal- lation ofall powered platforms and traveling ladders and gantries. Permanentpowered platforms shall be provided on all buildings with vertical platform travel exceeding 300 ft (91 m). 1.3.2 Deviations. Deviations from the requirements of this Standard maybe granted bythe enforcingauthorityif it is determined that a specific requirement creates prac- tical difficultyor excessive hardship, or where the specific requirementprevents the use ofanovel design, onlywhen equivalent safety is provided.
1.3.3 Alterations
(a) Any existing building being serviced may continue to be serviced until the building is altered, requiring a modification ofthe installation. Alteration ofthe building and equipmentmodification shall then be made to comply with the applicable parts of this Standard.
(b) If the authority having jurisdiction believes that hazards exist to warrant a change in an existing installa- tion, the authority may require compliance with any part ofthis Standard. Ifa qualified person deems thata hazard exists, the hazard shall be corrected, and the correction shall be in compliance with this Standard. (c) Once a building permit is issued or modified, the current version of the Standard shall apply.
1.4 Applicable Units This edition of the Standard uses U.S. Customary units with acceptable metric (SI) units shown in parentheses. NOTE: The metric values stated may not be exact equivalents to the U.S. Customary units. Information on the usage of SI units and their conver- sion from U.S. Customary units is contained in the IEEE/ ASTMSI 10-1997,StandardfortheUseoftheInternational System ofUnits (SI): The Modern Metric System; or ASME Guide SI-1, Orientation and Guide for Use of SI (Metric) Units.
