Or. Admin. R. 437-002-2027

Current through Register Vol. 63, No. 9, September 1, 2024

Section 437-002-2027 - Rope Descent & Rope Access Systems

(1) Scope and application. This rule establishes safety requirements for rope descent and rope access. Rope descent and rope access systems can provide a safe way for employees to reach hard-to-reach locations, either natural or man-made. The requirements of this rule include, but are not limited to, the cleaning of buildings or structures, the inspection of dams and spillways, access to interior or exterior structural and architectural components of buildings, highway/bridge inspection and maintenance, powerplant penstocks and other difficult access areas.

(2) Definitions. For the purposes of this rule the following definitions apply:

(a) Access is the means of reaching a workspace of a work area.

(b) Rope access means the use of rope access equipment where two ropes are used; one as the primary means of support and a second for fall arrest protection. The employee accesses the work area by ascending, descending, or traversing along both ropes by alternating connections and weight between the two ropes. Rope access may also be called industrial rope access but is not limited to industrial applications.

(c) Rope descent system 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, carabiner(s) or shackle(s), and a chair (seatboard). A rope descent system also is called controlled descent equipment or apparatus. Rope descent systems do not include industrial rope access systems.

(3) Personal Protective Equipment. The employer must ensure personal protective equipment is in accordance with Division 2/I when rope descent systems or rope access methods are used.

(4) Anchorages for Rope Descent and Rope Access Systems.

(a) Permanent Anchorages on Buildings.

(A) Before any rope descent or rope access system is used, the building owner must inform the employer, in writing that the building owner has identified, tested, certified, and maintained each permanent anchorage so it is capable of supporting at least 5,000 pounds (22.24kN), in any direction, for each employee attached. The information must be based on an annual inspection by a qualified person and certification of each anchorage by a qualified person, as necessary, and at least every 10 years.

(B) The employer must ensure that no employee uses any permanent anchorage before the employer has obtained written information from the building owner that each anchorage meets the requirements of 437-002-2027(4)(a)(A). The employer must keep the information for the duration of the job.

(C) The requirements of 437-002-2027(4)(a)(A) and (B) must be implemented no later than December 1, 2018.

(b) Temporary Anchorages. Anchorages for rope descent or rope access systems on structure or natural surroundings other than buildings must be independent from each other (primary support rope and secondary fall arrest system) and must be:

(A) Capable of supporting at least 5000 pounds (22.24 kN) for each employee attached: or

(B) Designed, installed, and used, under the supervision of a qualified person, as part of a complete system that maintains a safety factor of at least two.

(5) Rope descent systems. The employer must ensure:

(a) No rope descent system is used for heights greater than 300 feet (91 m) above grade unless the employer demonstrates that it is not feasible to access such heights by any other means or that those means pose a greater hazard than using a rope descent system;

(b) The rope descent system is used in accordance with instructions, warnings, and design limitations set by the manufacturer or under the direction of a qualified person;

(c) Each employee who uses the rope descent system is trained in accordance with 1910.30;

(d) The rope descent system is inspected at the start of each workshift that it is to be used. The employer must ensure damaged or defective equipment is removed from service immediately and replaced;

(e) The rope descent system has proper rigging, including anchorages and tiebacks, with particular emphasis on providing tiebacks when counterweights, cornice hooks, or similar non-permanent anchorages are used;

(f) Each employee uses a separate, independent personal fall arrest system that meets the requirements of 1910.140 in Division 2, Subdivision I;

(g) All components of each rope descent system, except seat boards, are capable of sustaining a minimum rated load of 5,000 pounds (22.2 kN). Seat boards must be capable of supporting a live load of 300 pounds (136 kg);

Note to 437-002-2027(5)(g): Oregon OSHA based this rule on federal OSHA's 1910.27(b)(2)(vii). Federal OSHA's discussion on final rule 1910.27(b)(2)(vii), as published on page 82577 of the Federal Register on November 18, 2016, states the following: "OSHA notes that the final rule does not preclude the use of lines or ropes that have knots, swage, or eye splice, which could reduce the tensile strength of a rope or line. However, under final paragraph (b)(2)(vii), even if an employer uses a line or rope that has a knot, swage, or eye split, the rope or line still must be capable of supporting a minimum rated load of 5,000 pounds."

(h) Prompt rescue of each employee is provided in the event of a fall, equipment malfunction or entanglement;

(i) The ropes of each rope descent system are effectively padded or otherwise protected, where they can contact edges of the building, anchorage, obstructions, or other surfaces, to prevent them from being cut or weakened;

(j) Stabilization is provided at the specific work location when descents are greater than 130 feet (39.6 m);

(k) No employee uses a rope descent system when hazardous weather conditions, such as storms or gusty or excessive wind, are present;

(l) Equipment, such as tools, squeegees, or buckets, is secured by a tool lanyard or similar method to prevent it from falling;

(m) The ropes of each rope descent system are protected from exposure to open flames, hot work, corrosive chemicals, and other destructive conditions;

(n) The ropes of each rope descent system are made from industrial synthetic fibers and classified as life-safety rope. Ropes made from natural fibers and polypropylene cannot be used for rope descent;

(o) Descent control devices include automatic locks that will engage and prevent an uncontrolled descent in case the employee lets go or loses control of the device;

(p) Anchorages for rope descent systems meet the requirements of 437-002-2027(4) of this rule; and

(q) A pre-work briefing is conducted with each employee involved in rope descent to include, but is not limited to:
