20210, although there will be a delay in our receiving correspondence by mail.Those in construction and general industry see some of the highest injury and fatality rates.

In general, this means using criteria that would be accepted by an industry consensus group or signed by a registered professional engineer. Since neither the standard nor the Appendix sets out test criteria for testing anchorages, employers may use any criteria that is scientifically valid. The Section II (b)(2) requirements simply ensure that the anchorage will not effect the system test results. 04 inches (1mm) when a force of 2,250 pounds (10Kn) is applied." That is one of several parameters for doing the test of the fall arrest system - it is not a means of establishing whether the anchorage has met the strength requirements in Section I. Section II (b), "General conditions for all tests in Section II," specifies that, when testing the fall arrest system, "(2) The anchorage should be rigid, and should not have a deflection greater than.
The Section II requirements are designed for use in a laboratory setting to (1) test the forces applied to a human body during an arrested fall (2) make sure the system's deceleration distance does not exceed 3.5 feet and (3) to make sure the system can arrest a fall without failure. Section II does not contain test criteria for testing the strength of anchorages. Can test requirements specified in Section II (b)(2) be applied to the anchorage requirements found in Section I, paragraph (c)(10)? If not, what are the applicable testing criteria for anchors used with personal fall arrest systems?Īnswer: No.

Section II, paragraph (a), states that Sections (b), (c), (d), and (e) of Section II may be used to determine compliance with the requirements of paragraph (d)(1)(i), (ii)(both of these address limiting of the maximum arresting force applied to an employee who has fallen), (iii)(maximum deceleration distance) and (iv) (strength of fall protection to withstand twice the potential impact energy of a free fall) of Section I. Section I, paragraph (c)(10), states that anchorages for personal fall arrest systems shall be capable of supporting at least 5,000 pounds. The other two parts, Sections II and III, are non-mandatory. The first part, Section I, contains mandatory provisions. Question 2 (for general industry only): Section 1910.66, Appendix C, has three parts. Section 1926.451(d)(18) requires such securing "as determined to be necessary based on an evaluation by a competent person." In contrast, securing is always required under §1910.28(g)(11). Note that the requirement to secure against swaying in §1926.451(d)(18) is somewhat different from the requirement in §1910.28(g)(11). For more information on stabilizing systems that will work with your specific scaffold, we suggest that you contact your scaffolding manufacturer or supplier. When using two-point suspension scaffolds, acceptable ways of securing the scaffold include, but are not limited to, mullion tracks and trolleys (guide rollers), intermittent tie-in guides employing detent pins, button-type stabilizer ties, and down-rigged lines. Both standards listed above state that "window cleaner's anchors shall not be used for this purpose." Suction cups are commonly used for "window cleaner anchors" therefore, the standards bar their use as stabilization anchors. Would an engineered suction cup system be an acceptable anchorage for securing the scaffold?Īnswer: No, an engineered suction cup system would not be an acceptable anchorage point for stabilizing a two-point suspension scaffold. Question 1 (for both construction and general industry work): Section 1926.451(d)(18), which applies to construction work, and § 1910.28(g)(11), which applies to general industry work, both require that two-point suspension scaffolds be secured to prevent them from swaying. We apologize for the delay in providing this response. This is in response to your October 18, 1999, letter in which you ask for clarification on OSHA requirements for securing two point suspension scaffolds to prevent swaying, and the requirements for testing anchorages for personal fall arrest systems as required by.
