In order to allow for user customization, the 021-4082 5K Swivel D-Ring Anchor assembly does not include a fastener. The user can choose to install a wedge or screw bolt with the anchor. The 021-4073 concrete wedge bolt and the 021-4053 concrete screw bolt are the recommended Safewaze products to use with the anchor. Safewaze equipment is designed for, and tested with, associated Safewaze components or systems. However, Hilti’s HSL4-B is a permitted bolt substitution. The use of competitor fasteners is permissible provided the user follows the Safewaze product manual, the chosen alternative fastener manual, and the following guidelines provided:
1. The alternative bolt has a diameter between 1/2’’ and 5/8’’.
2. The alternative bolt has an embedment depth of 41/2’’.
3. The alternative bolt is intended for concrete installation.
4. A Competent Person has determined the alternative fastener is capable of supporting intended loads on the anchor assembly.

Related Products: All Safewaze SRLs/SRL-Ps, FS8800SP-D, FS8800SP-L
Related Standards: ANSI A92.22-2021, EM 385-1-1
The use of a Safewaze Self-Retracting Lifeline (SRLs/SRL-Ps) for fall protection on a Mobile Elevated Work Platform (MEWPs) is permissible provided the user follows the Safewaze product manual and the following guidelines provided:
1. Use of an SRL/SRL-P will not ensure the user is properly restrained while the MEWP is in motion and could result in the user being ejected from the platform. The user should be secured to the engineered anchor point designed into the MEWP at all times. Additionally, the user should utilize a non-energy absorbing restraint lanyard/device which is connected to the side positioning D-rings of a full body harness when the platform is in motion. Connecting to the sternal, front, or dorsal D-rings will not provide adequate protection in a restraint application. SRLs can be adequately used for fall protection when the platform is stationary.
2. If there is an opportunity for the line constituent to encounter a sharp edge while conducting MEWP activities, a Class-2 leading edge SRL must be used.
3. A Class-1, Class-A, or Class-B SRL may be used only when there are no sharp edges and a leading edge is unnecessary, and as long as the aerial work platform has a guardrail system with a latching gate around its perimeter. This is not required if the anchorage position for the SRL is overhead.
4. It is mandatory that the energy absorbing portion of the SRL/SRL-P is mounted to the dorsal D-ring of the user’s harness. If an internal braking SRL is without an external energy absorber and is anchored at, or below, the dorsal D-ring’s height, the SRL may not function as intended. The line constituent could encounter the MEWP’s guard railing and create friction at that contact point, which may not allow the SRL to properly engage and arrest the fall. However, internal braking SRL models that do not incorporate an external energy absorber can be used if a separate, in-line energy absorber is installed between the end of the lifeline and the dorsal D-ring of the harness. By its attachment to the worker’s back, the added energy absorbing device allows proper deceleration as it isolates the friction on the lifeline. This protocol is highly recommended to reduce the risk of damaging the lifeline should a fall occur over the guardrail.
5. Safewaze offers two part numbers for this application:
a. FS8800SP-D — 18” Energy Absorber: Snap Hook, D-ring
b. FS8800SP-L — 20” Energy Absorber: Soft Loop, Snap Hook
6. When calculating fall clearance, efforts must be made to ensure there is a clear fall path available and enough free fall distance to engage the energy absorbing function of an SRL, or external energy absorber. When adding an additional energy absorber, greater fall clearance is required and must be taken into consideration.
7. The SRL’s lifeline extension speed must reach approximately 4.5 feet per second before the brake/absorber will engage and stop a fall. If a user fails to reach this speed, such as in a fall down a sloped surface, the SRL will not engage.
8. Employee training should be conducted to help ensure a safe working environment
9. When operating under the guidelines pursuant to EM 385-1-1, Safewaze SRLs are not allowed for use with Boom Supported Platforms/Boom Lifts.
10. Safewaze SRLs are suitable for use with Self-Propelled Elevating Work Platforms/Scissor Lifts. The Scissor Lifts must be equipped with anchorages that meet the ANSI Z359 Fall Protection Code in order for the SRLs to be utilized. This is also pursuant to requirements as specified in EM 385-1-1.

The most important factors to consider when wearing a safety harness are the same whether it is one issued to a single worker or one that will be shared by multiple workers.
The harness must always be a proper fit for the person wearing it. While every worker should check their harness for fit before each use, sharing a harness may mean it will need to be fully readjusted every time. Tongue buckle leg connections are often preferred for easier adjustment on a shared harness. Employees should be trained on how to properly fit the harness they will need to wear for the job.
The harness must always be a proper fit for the work environment. A harness may be shared between workers but not necessarily between functions. What works for one application may not work in another and could even create a greater hazard. For instance, a padded shoulder may add comfort in construction but be too hot in a factory. Even more critical, a construction harness would not be safe to use in a welding or arc flash environment.

Yes. OSHA requires employers to provide fall protection for each employee exposed to fall hazards. They do not, however, require each worker to have their own equipment. A harness with universal sizing has five areas of adjustment – chest strap, two torso adjusters and two leg buckles – to provide for different body shapes and sizes when different workers may share the same harness.

A VLL must be securely attached at the top and may or a not be attached at the bottom depending on application. They can be designed for use by one or multiple workers who use a positioning device, such as a rope grab, attached at the sternal (front) D-ring to control the worker’s movement up and down. The bottom end of the lifeline must be designed to ensure the rope grab does not slip off the lifeline and all VLLs must meet the OSHA guideline for minimum breaking strength of 5,000 lbs. These lifelines provide security in fall arrest and fall restraint for ladder and tower climbing as well as in roofing and general construction.

An HLL must be securely anchored at both ends and may also include intermediate anchor points. Designed for use by one or more workers, HLLs may be anchored overhead or at foot level. Connection is made with a device (Personal SRLs – SRL-Ps) that attaches the user to the HLL, or via an SRL that is anchored to the HLL and extended to connect to the user’s dorsal (back) D-ring. Connection to the HLL should be facilitated using an ANSI Z359.12-2019 compliant steel O-ring. User(s) should avoid direct connection to the HLL with a snap hook or carabiner as this may result in premature wear of lifeline components. All HLLs must comply with OSHA regulation 1926.502 and be, “designed, installed, and used under the supervision of a qualified person as part of a complete personal fall arrest system which maintains a safety factor of at least two.” These systems can provide increased freedom of movement while working on rooftops and in construction as well as providing fall protection solutions for window-washing, confined space operations and scaffolding.

Horizontal lifelines, known as HLLs, and vertical lifelines, known as VLLs, are important tools used as part of a complete fall protection system, providing anchorage for use with the appropriate harness and connector. Both types of lifelines utilize high-strength cable or rope which acts as the secure attachment point for fall arrest or fall restraint. They can be permanent or temporary. As the names imply, an HLL runs side to side (horizontally) while a VLL runs up and down (vertically) offering the worker additional range and mobility.

They can be designed for use by one or multiple workers who use a positioning device, such as a rope grab, attached at the sternal (front) D-ring to control the worker’s movement up and down. The bottom end of the lifeline must be designed to ensure the rope grab does not slip off the lifeline and all VLLs must meet the OSHA guideline for minimum breaking strength of 5,000 lbs. These lifelines provide security in fall arrest and fall restraint for ladder and tower climbing as well as in roofing and general construction.
