1、Designation: E2505 07 (Reapproved 2014)1Standard Practice forIndustrial Rope Access1This standard is issued under the fixed designation E2505; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in p
2、arentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEANSI references in 2.1, 6.1, and 6.2 were corrected editorially in June 2018.INTRODUCTIONThis standard applies where access is gained to structures, man-
3、made or natural, by means of ropessuspended from the structure or the features concerned. It applies to cases where ropes are used (1)as the primary means of support, (2) as the means of primary protection or positioning, and (3) whereoperatives descend or ascend on a rope, or traverse along a tensi
4、oned horizontal rope where the useof hands and feet can no longer be used to fully support the body.This standard is not intended to apply where rope access techniques are used by the fire department,other emergency services, and the armed forces. The authorities concerned with these activities have
5、their own standards for such work.This standard does not apply to other methods of working at height such as steeple jacking,suspended scaffolds, steelwork erection, or boatswains chairs.1. Scope1.1 This practice provides a framework of practical andtechnical information within which the specifying
6、authorityand the operators using rope access techniques can developeffective arrangements to help ensure the safety and health ofpersonnel involved in these projects.1.2 This practice applies to the use of techniques wherebyaccess is gained to structures, man-made or natural, by meansof ropes suspen
7、ded from the structure. It applies to all caseswhere ropes are used as the primary means of support andwhere persons descend or ascend a rope, or traverse along atensioned horizontal or inclined rope.1.3 This practice applies to all industrial uses of rope accesstechniques except use by the fire dep
8、artment and other emer-gency services for rescue work and training in connectiontherewith. Fire and rescue authorities have special proceduresapplicable to their circumstances. This standard does not applyto other methods of working at heights, such as suspendedscaffolds.1.4 The values stated in inc
9、h-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is t
10、heresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on stand
