ASME A120.1-2021 pdf download.Safety Requirements for Powered Platforms and Traveling Ladders and Gantries for Building Maintenance.
1 GENERAL RECOMMENDATIONS AND DEFINITIONS 1.1 Scope This Standard establishes safety requirements for powered platforms (scaffolds) for buildings where window cleaning and related services are accomplished by means ofsuspended 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 transpor- table equipment meeting the requirements of this Stan- dard. 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 ofthese scaffolds is included in ANSI A10.8-2001, Safety Requirements for Scaffolding. This Standard does not relate to any service performed bypersons supported byequipmentcovered byanyofthe ANSI A92 standards. 1.2 Purpose The purpose ofthis Standard is to ensure the protection of powered-platform users and traveling ladder and gantry users, and persons exposed to equipment used with 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 and gantries.
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.
1.5 ð21Þ Translation of Technical and Safety-Related Information 1.5.1All documentation, includingbutnotlimited to the following, shall be in English: (a) tagging and labeling (b) operating, maintenance, and other instructions (c) design and engineering data (d) records of use and inspection (e) installation logs (f) certifications 1.5.2 All pictograms included in the documentation shall comply with ISO 7000, ISO 7296, or another recog- nized source. 1.5.3 Ifthe original manufacturer’s documentation is in a language other than English and is translated to English to comply with para. 1.5.1, the translation shall meet professional translation industry standards, which include, but are not limited to, the following: (a) The translation shall (1) ensure grammatical accuracy (2) preserve the source document content without omitting or expanding the text (3) translate the terminology accurately (4) reflect the level of sophistication of the original document (b) Thefinishedtranslationshallbeverifiedforcompli- ance with (a) by a qualified person proficient in the tech- nical content of the subject matter. 1.5.4 If the manufacturer, engineer, or inspection per- sonnel no longer exist, and if a translation of their docu- mentation is necessary, the translation shall comply with paras. 1.5.1 through 1.5.3. 1.5.5 Ifthe documentation listed in para. 1.5.1 is trans- lated from its original English into another language, the translation shall comply with paras. 1.5.2 and 1.5.3.
