- If a Safewaze SRL is exposed to fall arrest or impact forces, it must be immediately removed from service and tagged “Unusable”.
- Never allow slack to form in the SRL lifeline constituent. Never tie or knot the lifeline.
- Utilize extra caution to keep the lifeline free from any obstructions including but not limited to; surrounding objects, tools, equipment, moving machinery, co-workers, yourself, or possible impact from overhead objects that could come into contact with the lifeline or worker.
- Avoid making sudden or quick movements as this could cause the SRL to inadvertently lock.
- Do not use a Safewaze SRL in an environment where the fall path is obstructed. Use of a Safewaze SRL on slowly shifting or unstable material such as grain or sand, or within cramped or confined spaces, may not allow the worker to reach adequate speed for the SRL lock up, resulting in possible engulfment.
- Work directly under the anchor point as much as possible to reduce the risk of striking an object due to a swing fall.
- Unused leg(s) of a harness-mounted SRL must be attached to the parking component on the front of the harness.
- If the PFAS is made up of components from different manufacturers, ensure that all components of the PFAS are compatible with each other and meet all applicable standards, regulations, or requirements. A Competent or Qualified Person should always review and approve the PFAS system before worker use.
- Avoid lifeline contact with sharp or abrasive surfaces.
- DO NOT use combinations of components or subsystems, or both, that may affect or interfere with the safe function of each other
- DO NOT alter equipment
- DO NOT misuse equipment
- Users must have a written Rescue Plan and means at hand to implement it when using this equipment. All employees should be trained and knowledgeable in the Rescue Plan and Rescue Operations.
- Avoid exposure of this equipment to chemicals, high heat, severe cold or other harsh environments which may produce a harmful effect.
- If in doubt about the serviceability of this equipment, contact Safewaze.
IMPORTANT
Users should enact the precautionary measures listed below to reduce the inherent risks of working at height
- Fall protection equipment that fails inspection must be removed from service and tagged “Unusable”. The equipment should then be returned to Safewaze for repair/service (if applicable) or destroyed. For questions regarding the service/repair of components, contact Safewaze.
- Never exceed the maximum allowable weight capacity of your fall protection equipment.
- Never exceed the maximum free fall distance of your fall protection equipment.
- Only Safewaze, or entities authorized in writing by Safewaze, may make repairs to Safewaze fall protection equipment.
- User(s) of Safewaze fall protection equipment must ensure that their health and physical condition allow them to withstand all forces and potential risks associated with working at heights. ANSI limits the weight capacity of fall protection equipment to a maximum of 310 lbs. Some equipment covered in this manual may indicate a weight capacity of over 310 lbs. Although some equipment maybe rated to a higher capacity, it should be noted that heavier users are at an increased risk of serious injury or death. This is due to increased forces on the body during a fall, and the risk for accelerated onset of suspension trauma.
- Use of a body belt is NOT authorized for fall arrest applications. Use only a Full Body Harness (FBH).
- Always wear required personal protective equipment when installing, using, or inspecting this equipment.
- If conducting training operations with this equipment, ensure that a secondary fall protection system is installed and utilized in a manner that does not expose the trainee to unintended fall hazards.
- Immediately seek medical attention in the event a worker suffers a fall arrest incident.
- Certain subsystems may interfere with the proper operation of the equipment in this manual. Use only compatible connections. Contact
- Safewaze for questions regarding compatibility of equipment or components not covered in this manual.
- Avoid objects, equipment, or surfaces that could harm the user or equipment.

TABLE 2 – ANSI STANDARDS
ANSI| Z359.14-2021| Safety Requirements for Self-Retracting Devices for
Personal Fall Arrest and Rescue Systems
---|---|---
- American National Standards Institute (ANSI) and Occupational Safety and Health Administration (OSHA):
- The SRLs covered in this manual meet ANSI Z359.14-2021, and Occupational Safety and Health Administration (OSHA) regulations 1910.140, 1910.66, 1926.502. ANSI requires SRLs be classified according to their intended use and are tested either as Class 1 or Class 2 units. Dynamic
- performance testing begins by installing the SRL in a controlled test environment. With the SRL attached to a suitable anchorage, the lifeline constituent is attached to a test weight.
- The weight is then dropped to simulate a fall arrest event. NOTE: SRL must be tested in all installation configurations allowed per its user instructions.
- Test results are recorded.
Parameters recorded are
- Arrest Distance (AD)
- Average Arrest Force (AAF)
- Maximum Arrest Force (MAF)
The Arrest Distance is the total vertical distance required to completely arrest a fall. The Arrest Distance includes the deceleration distance and the activation distance. The Average Arrest Force is the average of the forces applied to the body and the anchorage by the fall protection system. The Maximum Arrest Force is the maximum amount of force that may be applied to the body and the anchorage by the fall protection system. These tests are conducted in ambient conditions. The units must also be tested in extreme atmospheric conditions. There are three conditions: Cold, Hot, and Wet (Units saturated in water and tested). Separate units may be used for each test. All test results are recorded. This test data is then used to establish the fall clearance guidelines published in this user instruction manual.
Class 1 and 2
- Class 1: Self-retracting devices which shall be used only on overhead anchorages and shall be subjected to a maximum free fall of 2 feet (0.6 m) or less, in practical application.
- Class 2: Self-retracting devices that are intended for applications wherein overhead anchorages may not be available or feasible and which may, in practical application, be subjected to a free fall of no more than 6 feet (1.8 m) over an edge.
- When the SRL is anchored overhead of the user, ANSI Z359.14-2021 specifies that both Class 1 and Class 2 SRLs shall have an arrest distance of less than 42 in. (1.1 m). Average arrest forces must not exceed 1,350 lbs. (612.35 kg). Conditioned testing of the units allows slightly higher
- Average Arrest Forces of 1,575 lbs. (714.41 kg), but Maximum Arrest Forces must always remain below 1,800 lbs. (816.47 kg).
- When dynamically tested per requirements of ANSI Z359.14-2021, Class 1 and Class 2 Self-Retracting Devices must have an AAF of 1,350 lbs. (612.35 kg) or less and an AD of less than 42 in. (1.1 m).
- Class 2 SRL labels must include fall clearance table illustrations that include a diagram of the axes shown on the table. These labels shall be affixed to the product. Please see Section 10 of this user instruction manual for how to calculate your Minimum Required Fall Clearance (MRFC) using the affixed labels.
- Classification information found on product labels is based on test results. Table 1 indicates the SRLs covered in this manual. NOTE: Arrest distance is one of several parts of the Minimum Required Fall Clearance (MRFC). MRFC is discussed in detail in Section 10. OSHA requires an SRL to limit the free fall to 2 feet (0.6 m) or less. If the maximum free fall distance must be exceeded, the employer must document, based on test data, that the maximum arresting force will not be exceeded, and the personal fall arrest system will function properly.
WORKER CLASSIFICATIONS
-
Understand the definitions of those who work in proximity of or may be exposed to fall hazards or rescues.
-
Qualified Person: “Qualified Person” means one who, by possession of a recognized degree, certificate, or professional standing, or who by extensive
knowledge, training, and experience, has successfully demonstrated his ability to solve or resolve problems relating to the subject matter, the work, or the project. -
Competent Person: A “Competent Person” means one who is capable of identifying existing and predictable hazards in the surroundings or working conditions that are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
-
Authorized Person: “Authorized Person” means a person approved or assigned by the employer to perform a specific type of duty or duties or to be at a specific location or location at the job site.
-
It is the responsibility of a Qualified or Competent person to supervise the job site and ensure safety regulations are complied with.
TRAINING
This equipment is intended to be used by persons trained in its correct application and use. It is the responsibility of the user to ensure they are familiar with these instructions and are trained in the correct care and use of this equipment. Users must be aware of the operating characteristics, application, limits, and the consequences of improper use.
LIMITATIONS AND REQUIREMENTS
When installing or using this equipment always refer to the following requirements and limitations:
- Capacity: Safewaze Self-Retracting Lifelines are designed in compliance with ANSI Z359.14-2021 to meet the weight capacity range of (130-310 lbs), OSHA up to (420 lbs).
- Anchorage: Anchorages selected for fall arrest systems shall have a strength capable of sustaining static loads applied in the directions permitted by the system of at least:
- 5,000 lbs. (2267.9 kg) for non-certified anchorages, or
- Two times the maximum arresting force for certified anchorages.
When more than one fall arrest system is attached to an anchorage, the strengths outlined in (1) and (2) above shall be multiplied by the number of systems attached to the anchorage.
From OSHA 1926.502 and 1910.66:
Anchorages used for attachment of personal fall arrest systems shall be
independent of any anchorage being used to support or suspend platforms, and
capable of supporting at least 5,000 lbs. (2267.9 kg) per user attached, or be
designed, installed, and used as part of a complete personal fall arrest
system which maintains a safety factor of at least two, and is under the
supervision of a qualified person.
- Locking Speed: The nature of this equipment requires sufficient space in the working area to allow for the SRL to lock. Working in small or confined spaces may keep the user’s body from reaching the speed needed to lock the SRL during a fall. Working on slowly shifting materials, such as grain or sand, may not allow the speed needed to cause the SRL to lock.
- Swing Falls: As the user moves laterally away from an overhead anchor point, the risks related to swing falls increase. The force of striking an object involving a swing fall can in some instances generate more force than a fall with the user wearing no fall protection equipment. Minimize swing falls by working as directly below the anchorage point as possible.
- Free Fall: Safewaze SRLs when used correctly with the unit anchored directly overhead and no slack in the lifeline, will limit the free fall distance to 0 ft. (0 m). To limit free fall distances, keep the attachment of the SRL below the Dorsal D-ring height to as minimal a distance as possible.
- Safewaze Northstar Classic SRLs are not designed to allow for a foot-level tie-off.
- Fall Clearance: Figure 2 Illustrates a Fall Clearance Calculation. Fall Clearance (FC) is the total combined values of Free Fall (FF), Deceleration Distance (DD), and Safety Factor (SF). Safety Factor calculations may differ by manufacturer, but for this manual, the Safety
- The factor is calculated at 2 ft.. The Safety Factor includes a D-ring shift and Harness Stretch.
- Table 6-9 in this manual indicates the Minimum Fall Clearances when the Northstar Classic SRLs are anchored overhead. For falls from a kneeling or crouched position, an additional 3 ft. (1 m) of Fall Clearance is required. If a Swing Fall Hazard exists, the total vertical fall distance will be greater than if the user had fallen directly under the anchor point. Section 11 and Table 9 in this manual provide information regarding Swing Fall hazards and additional Fall Clearance Requirements.
- Hazards: Extra precautions should be taken if this equipment is used in an environment where hazards exist. Hazards can include but are not limited to: moving machinery, high voltage equipment or power lines, caustic chemicals, corrosive environments, toxic or explosive gases, or high heat. Avoid working in an area where overhead equipment or personnel could fall and contact the user, fall protection equipment, or the lifeline. Areas where the user’s lifeline may cross or tangle with the lifeline of another user should be avoided. Do not allow the lifeline to pass under arms or between the user’s legs.
- Sharp Edges: Safewaze Class 1 SRLs are NOT designed for use in Leading Edge Environments. Should a specific work area have an extremely sharp edge(s) that may come into contact with the lifeline constituent of the SRL, a Class 2 SRL is required.
INSPECTION FREQUENCY
Either the Authorized Person¹ (User) or the Rescuer² must inspect this equipment before each use. The Inspection table (Table 3), should be used to determine proper inspection frequency. The Inspection Form (Page 15) describes proper inspection procedures. The Competent Person should record inspection results in the Inspection Form and retain a copy for records. (NOTE: User is advised to make copies of the Inspection Form on (Page 15) of this manual before filling out the form for the first time). Copies of the Inspection Form can be used for later Inspections. Annual inspections by a Competent Person other than the user must be recorded in the Inspection Log.
- Authorized Person: A person assigned by the employer to perform duties at a location where such person will be exposed to a fall hazard.
- Rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
NOTE: Special rescue measures may be required for a fall over an edge.

Minimum Required Fall Clearance
Safewaze SRLs are tested under ANSI Z359.14-2021 conditioning test protocols.
Table 6 reflects the actual performance of each unit in the Northstar Classic
SRL series when subjected to Ambient, Wet, Hot, and Cold testing. The Fall
Clearance specifications in Table 8 of this manual reflect the ANSI
Z359.14-2021 Maximum Arrest Distance allowance of 42”. Actual Arrest Distances
for each unit in the Northstar Classic SRL series are indicated below.
These Actual Arrest Distances are typically lower than the 42” maximum as
specified per ANSI. In certain instances this may allow for a Qualified Person
to adjust Minimum Required Fall Clearances indicated in Table 8.
The Minimum Required Fall Clearance distances indicated in Table 7 are based
on Ambient, Wet, Hot, and Cold testing results for each unit in the Northstar
Classic SRL series. Fall Clearances indicated in Table 7 are calculated using
the greatest Actual Arrest Distance out of the four tests performed on each
model.
Table 6 indicates the specific arrest distance for each unit in prescribed
condition testing with a 0’ offset.
EXAMPLE: The FS-FSP1215-G has Actual Arrest Distances of 16”, 17”, 17”,
and 34” during Ambient, Wet, Hot, and Cold testing respectively.
By using the greatest distance (Cold=34”) out of the four tests performed and
inserting that value in Row B of the Chart in Figure 2, a Total Fall Clearance
of 6’ 10” is required.

An anchorage point located in a position that is not directly over the user’s fall location results in a Swing Fall (See Figure 3). Swing falls may result in the user striking an object with enough force to cause serious injury. Greater clearance is needed to ensure safety during a swing fall as vertical fall distance will be greater than a fall originating directly below the anchorage point. For help determining additional required fall clearance due to Swing Fall, (See Table 9).
WARNING: The risk of striking an object or obstruction is dramatically increased during a swing fall. Failure to comply with this warning may result in serious injury or death.

Using Table 9:
Table 9 provides the ability for the user to determine additional fall clearance requirements if a Swing Fall Hazard is present when using the Northstar Classic SRL in an overhead application. The Y-Axis represents the height the SRL is anchored above the user’s Dorsal D-ring. The X-Axis represents the lateral movement of the worker concerning the SRL.
Example – Northstar Classic SRL Anchored Overhead:
This example represents the user anchored 5’ Overhead (Up along the Y-Axis) and 4’ Laterally (Along the X-Axis). The intersection of these distances on the chart indicates an additional 1’ of fall clearance required. This additional required fall clearance must be added to total fall clearance calculations.
FALL PROTECTION AND RESCUE PLAN
- When using this equipment, employers must create and maintain a Fall Protection and Rescue Plan and provide the means to implement those plans. The plans must be communicated to equipment users, authorized persons, and rescuers. These plans must meet ANSI Z359.2 “Minimum
- Requirements for a Comprehensive Managed Fall Protection Program.” They should include the requirements and guidelines for the employer’s managed Fall Protection Program.
- This would include eliminating and controlling fall hazards, duties and training, policies, fall protection procedures, rescue procedures, incident investigations, and evaluation of the program’s effectiveness.
NORMAL OPERATIONS
During normal operations, the lifeline constituent of the SRL will extend and retract freely with no slack or hesitation as the worker moves at normal speeds. In the event of a fall, Safewaze SRLs are equipped with a speed sensing braking system. The braking system will activate, stopping the fall, and absorbing much of the energy created by the fall. Due to the speed sensing braking system, user(s) should avoid quick or sudden movements, as this may cause the SRL to inadvertently lock. If the user is performing operations near the end of the working length of the SRL, a reserve line is incorporated within the SRL to reduce fall arrest forces.
COMPATIBILITY OF COMPONENTS
Safewaze Fall Protection Equipment is designed for use with Safewaze components and subsystems only. A Qualified Person should make the determination of Safewaze equipment compatibility with equipment not manufactured by Safewaze. Replacement or substitution of equipment not manufactured by Safewaze, may degrade, or reduce the safety and reliability of the complete system.
IMPORTANT: Read and follow the manufacturer’s instructions for associated components and subsystems in your fall arrest system.
COMPATIBILITY OF CONNECTORS
Connectors are compatible with connecting elements when they have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to inadvertently open, regardless of how they become oriented. Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbs. (2267.9 kg). Connectors must be compatible with the anchorage or other system components (See Figure 4). Do not use equipment that is not compatible. Non-compatible connectors may unintentionally disengage (See Figure 4). Connectors must be compatible in size, shape, and strength. Self-locking snap hooks and carabiners are required by ANSI Z359 and OSHA guidelines. Contact Safewaze if you have any questions about compatibility.
NOTE: SOME SPECIALTY CONNECTORS HAVE ADDITIONAL REQUIREMENTS. CONTACT SAFEWAZE WITH QUESTIONS.
Using a connector that is undersized or irregular in shape (1) to connect a snap hook or carabiner could allow the connector to force open the gate of the snap hook or carabiner. When force is applied, the gate of the hook or carabiner presses against the non-compliant part (2) and forces open the gate (3). This allows the snap hook or carabiner to disengage (4) from the connection point.
MAKING CONNECTIONS
Snap hooks and carabiners used with this equipment must be double-locked and/or twist lock. Ensure all connections are compatible in size, shape and strength. Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked. Safewaze connectors (snap hooks and carabiners) are designed to be used only as specified in each product’s user’s instructions. (See Figure 5) for examples of inappropriate connections. Do not connect snap hooks and carabiners
- To a D-ring to which another connector is attached.
- In a manner that would result in a load on the gate (except for Tie-Back hooks). NOTE: Large snap hooks must not be connected to objects which will result in a load on the gate if the hook twists or rotates, unless the snap hook complies with ANSI Z359.12 and is equipped with a 3,600 lbs. (1632.9 kg) gate. Check the marking on your snap hook to verify its compatibility.
- In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and without visual confirmation seem to be fully engaged to the anchor point.
- To each other.
- By wrapping the lifeline around an anchor and securing to the lifeline except as allowed for Tie-Back models
- To any object that is shaped or sized in a way that the snap hook or carabiner will not close and lock, or that roll-out could occur.
- In a manner that does not allow the connector to align properly while under load.
NOTE: Large throat snap hooks must not be connected to standard size D-rings or similar objects which will result in a load on the gate if the hook or D-ring twists or rotates, unless the snap hook complies with ANSI Z359.12 and is equipped with a 3,600 lbs. (1632.9 kg) gate. Check the marking on your snap hook to verify that it is appropriate for your application.
USE
WARNING: Contact Safewaze if you have questions regarding the
compatibility of this equipment that are not covered in this manual. Do not
alter or misuse this equipment. Some subsystem components could affect the
performance of the operation of this equipment. Do not anchor this product to
moving machinery, or hazards that include chemical, electrical or gaseous
characteristics. Failure to comply with this warning could result in injury or
death.
WARNING: Consult your doctor if there is reason to doubt your fitness to
safely absorb the shock from a fall arrest. Age and fitness seriously affect a
worker’s ability to withstand falls. Pregnant women or minors must not use
Safewaze SRLs. Failure to heed this warning may result in serious injury or
death.
OPERATION
Inspect the SRL as described in Section 19, before using the equipment. Refer
to Figure 6 for common system connections used with SRL applications. Mount
the SRL to an approved anchor point. Ensure connections are compatible in
size, shape, and strength. Ensure hooks are fully closed and locked. When the
worker is fully attached, the worker is then free to move about within the
recommended working area. If a fall occurs, the SRL will lock and arrest the
fall. Upon rescue, remove the SRL from use. When working with an SRL, always
allow the lifeline to retract back into the device in a controlled manner. Do
not release the unit to “free-spin” back into itself.
WARNING: Do not tie or knot the lifeline. Avoid lifeline contact with
sharp or abrasive surfaces. Inspect the lifeline frequently for cuts, fraying,
burns, or signs of chemical damage. Dirt, contaminants, and water can lower
the performance of the lifeline. Use caution near power lines. Failure to
comply with this warning may result in serious injury or death.
AFTER A FALL
- As discussed in Section 12, employers must create and maintain a Fall Protection and Rescue Plan and provide the means to implement those plans.
- ANSI Z359.2 “Minimum Requirements for a Comprehensive Managed Fall Protection Program ” specifies “The employer shall provide prompt rescue to all fallen authorized persons”, with a recommended goal for rescue subject contact of less than 6 minutes. While there is no specific criteria for what constitutes a “prompt rescue”, all workers must be trained on the site Rescue Plan, and all equipment associated with the Rescue Plan.
- Any equipment exposed to the force of a fall, or that shows damage consistent with the effects of a fall, must be removed from service immediately. Equipment must then be serviced (See Section 18) if applicable, or disposed of (See Section 19).
BODY SUPPORT
- A full-body harness must be worn when using Safewaze SRL
SYSTEM CONNECTIONS
Figure 6 illustrates some typical examples of harness and anchorage
connections for Northstar Classic SRLs. When using a snap hook to make a
connection, ensure roll-out cannot occur (See Figure 4). Do not use snap hooks
or carabiners that will not completely close over the anchor point. This
includes traditional overhead anchor point tie-off, housing attachment to
dorsal D-ring, and 100% tie-off. Follow the manufacturer’s instructions
supplied with each system component.
WARNING: Never connect the snap hook of one SRL to the lifeline of
another SRL or lanyard. Failure to comply with this warning may result in
equipment malfunction, serious injury or death.
ANCHORAGE
Select an anchorage location with minimal free fall and swing fall hazards.
Select a rigid anchorage point capable of sustaining static loads as defined
in Section 6. Where anchoring overhead is not feasible, the user must ensure
that a Class 2 SRL is used for any circumstance that requires anchoring of the
SRL below the user’s dorsal D-ring. CLASS 1 SRLs ARE NOT AUTHORIZED FOR USE
BELOW THE DORSAL D-RING OF A FULL BODY HARNESS!
IMPORTANT: Do not allow the lifelines to pass under the arms or between
the legs.
PERFORMANCE
- Safewaze SRLs have been tested and certified to the performance requirements of the standard(s) identified on their ID labels. See Figure 8 for examples of product labelling.
MAINTENANCE, SERVICE, AND STORAGE
MAINTENANCE
- Cleaning procedures for Safewaze SRLs are as follows:
- Periodically clean the exterior of the SRL using water and a mild soap solution. Clean labels to maintain readability.
- An excessive buildup of debris on the cable or web lifeline of the SRL may prevent the lifeline from fully retracting back into the housing. Improper retraction of the lifeline constituent of the SRL could create a potential free fall hazard.
- Clean cable lifelines using an acid-free oil or petroleum jelly at regular intervals. Always wear gloves when servicing/inspecting steel cable SRLs.
- Clean web lifelines with mild detergent and warm water. Allow web lifeline to air dry completely before retracting back into the housing. DO NOT USE HEAT to dry web lifeline.
IMPORTANT: If the lifeline comes in contact with acids or other caustic chemicals, remove the SRL from service and wash with water and a mild soap solution. Inspect the SRL (using the Inspection Form on Page 19) before returning to service.
SERVICE
Only Safewaze or entities authorized in writing by Safewaze, shall make repairs to this equipment. Remove the SRL from use if the SRL has been subjected to fall arrest forces or has been used to affect a rescue. If unrepairable dispose of the SRL as recommended in Section 19. For questions regarding disposal, service, or repair of Safewaze SRLs, contact Safewaze at 800-230-0319.
STORAGE
Store Safewaze SRLs in a cool, dry, clean environment out of direct sunlight. Avoid areas where chemical vapors may exist. Thoroughly inspect the SRL after any period of extended storage.
INSPECTION
PRIOR TO EACH USE
Before each use ensure that the equipment is in good working condition. Inspect the unit to ensure it has not been damaged and that the unit pays out and retracts properly. Prior to each use, the braking system must be inspected. Grasp the body of the unit in one hand and the cable or web lifeline in the other. With a quick, jerking motion, pull down on the cable/web. The brake should engage, stopping movement almost immediately. Inspect the cable/web (using the Inspection Form on Page 15) and ensure that all connection hardware is working properly. Brake failure or unsatisfactory results during any portion of the inspection requires immediate removal of the SRL from service. Figure 9 points out key inspection areas of the Northstar Classic series of SRLs.
UNSAFE OR DEFECTIVE CONDITIONS
Figure 7 shows examples of equipment damage. Equipment inspectors must be trained to look for damage as illustrated in Figure 7, as well as other damage that may occur. If inspection reveals an unsafe or defective condition remove the SRL from service.
PRODUCT LIFE
- The working life of Safewaze SRLs are determined by work conditions, care, maintenance, and proper inspections. As long as the SRL passes inspection, it may remain in service.
DISPOSAL
Dispose of the Safewaze SRL if it has been damaged by fall arrest forces or inspection reveals an unsafe or defective condition that cannot be repaired by an authorized Safewaze Service Center. Before disposing of the SRL, cut the lifeline in half so that it is not mistakenly reused. For questions regarding disposal, service, or repair of Safewaze SRLs, contact Safewaze at 800-230-0319.
