【国外标准】 Standard Practice for Industrial Rope Access (Withdrawn 2023)

4.1 Access to the exterior and interior of structures is often required as part of maintenance or inspection work. Depending on the characteristics of the structure and site constraints, access can often be achieved using a number of methods other than industrial rope access, including ladders, stationary or removable suspended scaffolding, mechanical self-propelled aerial lifts, and other suitable means. There are instances where use of such means of access is not feasible or economical.4.2 This standard provides guidance on the use of rope access as an alternative to other methods of access.1.1 This practice provides a framework of practical and technical information within which the specifying authority and the operators using rope access techniques can develop effective arrangements to help ensure the safety and health of personnel involved in these projects.1.2 This practice applies to the use of techniques whereby access is gained to structures, man-made or natural, by means of ropes suspended from the structure. It applies to all cases where ropes are used as the primary means of support and where persons descend or ascend a rope, or traverse along a tensioned horizontal or inclined rope.1.3 This practice applies to all industrial uses of rope access techniques except use by the fire department and other emergency services for rescue work and training in connection therewith. Fire and rescue authorities have special procedures applicable to their circumstances. This standard does not apply to other methods of working at heights, such as suspended scaffolds.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
