ASME A120.1:2006 pdf download Safety Requirements for Powered Platforms and Traveling Ladders and Gantries for Building Maintenance
GENERAL RECOMMENDATIONS ANDDEFINITIONS
1.1 Scope
This Standard establishes safety requirements forpowered platforms (scaffolds) for buildings where window cleaning and related services are accomplished bymeans of suspended equipment at heights in excess ol35 ft (11 m) above a safe surface (e.g, grade, street, floor,or roof level). Additionally, this Standard establishessafety requirements for permanent traveling ladders andgantries (TLG).
It pertains to either permanently installed or transportable equipment meeting the requirements of thisStandard.
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 scaffolds is included in ANSI A10.8-2001, Safety Requirements for Scaffolding.
This Standard does not relate to any service performedby persons supported by equipment covered by any ofthe ANSI A92 standards.
1.2 Purpose
The purpose of this Standard is to ensure the protection of powered platform users and traveling ladder andgantry users, and persons exposed to equipment usedwith the previously described maintenance of buildingsIt is also intended for use by architects, engineersdesigners, manufacturers, inspectors, purchasers, build.ing owners, and others associated with the installation ofpowered platforms and traveling ladders and gantriesAdditionally, it is recommended for use by enforcement agencies having jurisdiction over the installationof powered 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 Applications. This Standard applies to theinstallation of all powered platforms and traveling lad-ders and gantries.
1.3.2 Deviations. Deviations from the requirementsof this Standard may be granted by the enforcing author-ity if it is determined that a specific requirement createspractical difficulty or excessive hardship, or where thespecific requirement prevents the use of a novel designonly when equivalent safety is provided.
1.33 Alterations
(a) Any existing building being serviced may continue to be serviced until the building is altered, requiring a modification of the installation. Alteration of thebuilding and equipment modification shall then bemade to comply with the applicable parts of thisStandard.
(b) If the authority having jurisdiction believes thathazards exist to warrant a change in an existing installa-tion,the authority may require compliance with anypart of this Standard. If a qualified person deems thata hazard exists, the hazard shall be corrected, and thecorrection shall be in compliance with this Standard.(c) Once a building permit is issued or modified, thecurrent version of the Standard shall apply.
1.4 References
When a nationally recognized standard, other thanthat specifically referred to in para. 1.1, is referred toand is superseded by a revision, the edition current atthe time of acceptance of this Standard shall apply.
