Dear Mr. Bright:
This is in response to a letter to the Occupational Safety and Health Administration (OSHA) from International Window Cleaning Association’s past-president Jason York, requesting clarification of the OSHA standard at 29 CFR § 1910.27(b), Rope descent systems, as it may apply to the Industrial Rope Access Systems (IRAS). This letter constitutes OSHA’s interpretation only of the requirements discussed and may not be applicable to any question not delineated within your original correspondence. Your paraphrased questions and our responses are below.
Question 1: If an industrial rope access system is used on a building in a manner which allows a worker to descend in a controlled manner and, as needed, stop at any point during the descent to perform work, then will it be considered by OSHA to be a rope descent system (RDS) as defined in 29 CFR § 1910.21(b)?
Response 1: No. Under 29 CFR § 1910.21(b), RDS means “a suspension system that allows an employee to descend in a controlled manner and, as needed, stop at any point during the descent. A rope descent system usually consists of a roof anchorage, support rope, a descent device, carabineer(s) or shackle(s), and a chair (seat board). A rope descent system also is called controlled descent equipment or apparatus. Rope descent systems do not include industrial rope access systems.” The definition for RDS clarifies that rope descent systems do not include IRAS. As such, 29 CFR § 1910.27(b) does not cover or apply to IRAS. However, other OSHA fall protection standards, including 29 CFR §§ 1910.28, 1910.29, 1910.30, 1910.140 apply to IRAS, and IRAS anchorage requirements are covered under 29 CFR §§ 1910.140(c)(12), 1910.140(c)(13) through 1910.140(c)(13)(ii).
Question 2: Do identification and certification requirements for anchorages under 29 CFR § 1910.27(b) apply to building owners or employers when IRAS are used on a building to perform work in the same manner that an RDS would be used?
Response 2: No. The requirements contained in 29 CFR § 1910.27(b), including the identification and certification requirements for anchorages, do not apply to IRAS.
