I am sorry, but I cannot provide information about EM-385-1-1. However, I can share some general guidelines regarding tie-off points when using personal fall arrest systems.

When using personal fall arrest systems, it's crucial to plan the system before use, paying close attention to suitable anchorage points [1]. Ideally, this planning should occur during the structure's construction to incorporate anchorage points for future maintenance 2, 3. If anchorages must be installed immediately before use, a registered professional engineer or qualified person should design the anchor point [1].

Here are some key considerations for tie-off points:

  • Strength: Anchorages must support at least 5,000 pounds (22.2 kN) per attached employee or be part of a complete personal fall arrest system with a safety factor of at least two, under the supervision of a qualified person [2].
  • Location: The tie-off attachment point to the lifeline or anchor should be at or above the connection point of the fall arrest equipment to the harness to minimize free fall distance 5, 8.
  • Free Fall Distance: Minimize free fall distance, ensuring it does not exceed 6 feet (1.8 m) 5, 8.
  • Obstructions: Consider potential obstructions in the employee's fall path to minimize swing fall hazards [3].
  • Compatibility: Ensure ropes, belts, lanyards, and harnesses are compatible with all connectors used [2].
  • Alternatives: If proper anchor points are unavailable, steel members or I-beams (using acceptable straps), large eye-bolts, or guardrails designed as anchor points may be used. A qualified person should assess the suitability of these makeshift anchorages [4].

It's also important to be aware of situations that can reduce the strength of the fall arrest system:

  • Avoid using knots in lanyards or lifelines, as they can reduce strength by 50% or more 2, 4, 19.
  • Avoid tie-off around sharp or rough surfaces, which can damage the rope and reduce strength 2, 4, 19.
  • Ensure locking snap-hooks are used for all connections to prevent roll-out [5].

Remember to inspect personal fall arrest systems regularly for any defects and remove damaged components from service 3, 10, 14. Also, provide thorough employee training on the selection, use, and inspection of personal fall arrest systems 10, 17, 20.

Division 3 Oregon Administrative Rules Oregon Occupational Safety and Health Division - (ii) In other cases, the Agency recognizes that there will be a need to devise an anchor point from existing structures. Examples of what might be appropriate anchor points are steel members or I-beams if an acceptable strap is available for the connection (do not use a lanyard with a snaphook clipped onto itself); large eye-bolts made of an appropriate grade steel; guardrails or railings if they have been designed for use as an anchor point; or masonry or wood members only if the attachment point is substantial and precautions have been taken to assure that bolts or other connectors will not pull through. A qualified person should be used to evaluate the suitable of these 'make shift' anchorages with a focus on proper strength. - (2) Employers and employees should at all times be aware that the strength of a personal fall arrest system is based on its being attached to an anchoring system which does not reduce the strength of the system (such as a properly dimensioned eye-bolt/snap-hook anchorage). Therefore, if a means of attachment is used that will reduce the strength of the system, that component should be replaced by a stronger one, but one that will also maintain the appropriate maximum arrest force characteristics. - (3) Tie-off using a knot in a rope lanyard or lifeline (at any location) can reduce the lifeline or lanyard strength by 50 percent or more. Therefore, a stronger lanyard or lifeline should be used to compensate for the weakening effect of the knot, or the lanyard length should be reduced (or the tie-off location raised) to minimize free fall distance, or the lanyard or lifeline should be replaced by one which has an appropriately incorporated connector to eliminate the need for a knot. - (4) Tie-off of a rope lanyard or lifeline around an 'H' or 'I' beam or similar support can reduce its strength as much as 70 percent due to the cutting action of the be

Oregon Occupational Safety and Health Division Oregon Administrative Rules Division 3 - (f) Rescue considerations. As required by §1926.502(d)(20), when personal fall arrest systems are used, the employer must assure that employees can be promptly rescued or can rescue themselves should a fall occur. The availability of rescue personnel, ladders or other rescue equipment should be evaluated. In some situations, equipment which allows employees to rescue themselves after the fall has been arrested may be desirable, such as devices which have descent capability. - (g) Inspection considerations. As required by §1926.502(d)(21), personal fall arrest systems must be regularly inspected. Any component with any significant defect, such as cuts, tears, abrasions, mold, or undue stretching; alterations or additions which might affect its efficiency; damage due to deterioration; contact with fire, acids, or other corrosives; distorted hooks or faulty hook springs; tongues unfitted to the shoulder of buckles; loose or damaged mountings; non-functioning parts; or wearing or internal deterioration in the ropes must be withdrawn from service immediately, and should be tagged or marked as unusable, or destroyed. - (h) Tie-off considerations. - (1) One of the most important aspects of personal fall protection systems is fully planning the system before it is put into use. Probably the most overlooked component is planning for suitable anchorage points. Such planning should ideally be done before the structure or building is constructed so that anchorage points can be incorporated during construction for use later for window cleaning or other building maintenance. If properly planned, these anchorage points may be used during construction, as well as afterwards. - (i) Properly planned anchorages should be used if they are available. In some cases, anchorages must be installed immediately prior to use. In such cases, a registered professional engineer with experience in desi

Division 2 AO 2-2023 Oregon Administrative Rules Oregon Occupational Safety and Health Division - (12) Anchorages used to attach to personal fall protection equipment must be independent of any anchorage used to suspend employees or platforms on which employees work. Anchorages used to attach to personal fall protection equipment on mobile work platforms on powered industrial trucks must be attached to an overhead member of the platform, at a point located above and near the center of the platform. - (13) Anchorages, except window cleaners' belt anchors covered by paragraph (e) of this section, must be: - (i) Capable of supporting at least 5,000 pounds (22.2 kN) for each employee attached; or - (ii) Designed, installed, and used, under the supervision of qualified person, as part of a complete personal fall protection system that maintains a safety factor of at least two. Note to 1910.140(c)(13): In Oregon, the performance, care, and use criteria for travel restraint systems (personal fall restraint) is in OAR [redacted phone](5)(b) in Division 2/I. - (14) Travel restraint lines must be capable of sustaining a tensile load of at least 5,000 pounds (22.2 kN). - (15) Lifelines must not be made of natural fiber rope. Polypropylene rope must contain an ultraviolet (UV) light inhibitor. - (16) Personal fall protection systems and their components must be used exclusively for employee fall protection and not for any other purpose, such as hoisting equipment or materials. - (17) A personal fall protection system or its components subjected to impact loading must be removed from service immediately and not used again until a competent person inspects the system or components and determines that it is not damaged and safe for use for employee personal fall protection. - (18) Personal fall protection systems must be inspected before initial use during each work shift for mildew, wear, damage, and other deterioration, and defective components must be removed fro

The reason for this is that in multiple tie-offs to a horizontal lifeline, if one employee falls, the movement of the falling employee and the horizontal lifeline during arrest of the fall may cause other employees to also fall. Horizontal lifeline and anchorage strength should be increased for each additional employee to be tied-off. For these and other reasons, the design of systems using horizontal lifelines must only be done by qualified persons. Testing of installed lifelines and anchors prior to use is recommended. - (g) The strength of an eye-bolt is rated along the axis of the bolt and its strength is greatly reduced if the force is applied at an angle to this axis (in the direction of shear). Also, care should be exercised in selecting the proper diameter of the eye to avoid accidental disengagement of snap-hooks not designed to be compatible for the connection. - (h) Due to the significant reduction in the strength of the lifeline/lanyard (in some cases, as much as a 70% reduction), the sliding hitch knot should not be used for lifeline/lanyard connections except in emergency situations where no other available system is practical. The 'one-and-one' sliding hitch knot should never be used because it is unreliable in stopping a fall. The 'two-and-two,' or 'three-and-three' knot (preferable), may be used in emergency situations; however, care should be taken to limit free fall distance to a minimum because of reduced lifeline/lanyard strength. - (9) Vertical lifeline considerations. As required by the standard, each employee must have a separate lifeline when the lifeline is vertical. The reason for this is that in multiple tie-offs to a single lifeline, if one employee falls, the movement of the lifeline during the arrest

Because of this, the free fall distance should be kept at a minimum, and, as required by the standard, in no case greater than 6 feet (1.8 m). To help ensure this, the tie-off attachment point to the lifeline or anchor should be located at or above the connection point of the fall arrest equipment to harness. (Since otherwise additional free fall distance is added to the length of the connecting means (i.e. lanyard).) Attaching to the working surface will often result in a free fall greater than 6 feet (1.8 m). For instance, if a 6 foot (1.8 m) lanyard is used, the total free fall distance will be the distance from the working level to the body harness attachment point plus the 6 feet (1.8 m) of lanyard length. Another important consideration is that the arresting force which the fall system must withstand also goes up with greater distances of free fall, possibly exceeding the strength of the system. - (12) Elongation and deceleration distance considerations. Other factors involved in a proper tie-off are elongation and deceleration distance. During the arresting of a fall, a lanyard will experience a length of stretching or elongation, whereas activation of a deceleration device will result in a certain stopping distance. These distances should be available with the lanyard or device's instructions and must be added to the free fall distance to arrive at the total fall distance before an employee is fully stopped. The additional stopping distance may be very significant if the lanyard or deceleration device is attached near or at the end of a long lifeline, which may itself add considerable distance due to its own elongation. As required by the standard, sufficient distance to allow for all of these factors
