- Do not use this device for horizontal use or with horizontal lifeline systems, unless approved by the manufacturer.
- Never work above the device.
- The device should be installed and used in such a manner as to minimize the potential for a swing fall.
- Never allow the lifeline to become slack while being used for fall protection or while in rescue mode.
- Do not allow the lifeline in any application to bend or be subjected to fall-arresting forces over structural members or edges.
- Never use the device as a restraint or positioning device.
- The retrieval mechanism in the MightEvac is FOR EMERGENCY USE ONLY. Do not use it for routine hoisting of personnel or materials.
System Compatibility
- Honeywell Miller fall protection products are designed for use with Honeywell-approved components only. Substitution or replacement with non-approved component combinations or subsystems or both may affect or interfere with the safe function of each other and endanger the
- compatibility within the system. This incompatibility may affect the reliability and safety of the total system.
WARNING
- Always refer to the regulations and standards regarding personal fall arrest system component requirements and the instructions provided with each component being used as part of the personal fall arrest system.
Personal Fall Arrest System Components
- Three key components of the Personal Fall Arrest System (PFAS) need to be in place and properly used to provide maximum worker protection
(see Fig. A)
A) ANCHORAGE / ANCHORAGE CONNECTOR
- The anchorage, also referred to as the anchor point or tie-off point, is a secure point of attachment for connecting devices and must be capable of supporting 5,000 lb (22.2kN) per worker or meet
- OSHA requirements for a safety factor of two, such as an I-beam or other support structure. An anchorage connector, such as the cross-arm strap, D-bolt or rebar hook anchor, is sometimes necessary to make a compatible connection between the connecting device and the anchorage.
B) BODY WEAR
- Body wear is a personal protective gear worn by the worker while performing the job. The only form of body wear acceptable for fall arrest is the full-body harness.
- It is imperative that the harness be worn properly. Visually check all buckles to ensure proper and secure connections before each use. All straps must be connected and adjusted to provide a snug fit.
- Fall protection connecting devices should be attached to the back D-ring of the full-body harness. A sternal D-ring attachment element may be used for fall arrest only in rescue, work positioning, rope access, and other recognized applica- tions where the personal fall arrest system limits the maximum free fall distance to 2 ft (0.6m) and limits the maximum arrest force to 1800 lb (8kN).
- Side and sternal D-rings should be used for positioning only. (Note front D-ring exception above.); shoulder D-rings should be used for retrieval, raising or lowering only.
- Never attach rebar (pelican) hooks to a harness D-ring. Body belts should be used for positioning and restraint only.
C) CONNECTING DEVICE
- Connecting device is the critical link which joins the body wear to the anchorage/anchorage connector. The most important feature of the connecting device is the built-in shock absorber. Whether the connecting device is a shock-absorbing lanyard or Self-Retracting Lifelines, they are designed to dramatically reduce fall arrest forces. Rope, web or wire rope lifelines being used for fall arrest MUST be used in conjunction with a shock absorber (i.e., Miller SofStop pack).
Individually, none of these components will provide protection from a fall. However, when used properly and in conjunction with each other, they form a Personal Fall Arrest System that becomes vitally important to safety on the job site.
Anchorage Requirements
- The anchorage must be capable of supporting 5,000 lb (22.2kN) per worker; or it must be designed, installed, and used under the supervision of a qualified person as part of a complete fall arrest system which maintains a safety factor of two.
- ANSI anchorage requirements are as follows:
- For fall arrest systems, anchorages must withstand a static load of 5,000 lb (22.2kN) for non-certified anchorages or two times the maximum arresting force for certified anchorages.
- For rescue systems only, anchorages must withstand a static load of 3,000 lb (13.3kN) for non-certified anchorages or five-times the applied load for certified anchorages. (NOTE: When an anchorage may be used for both fall arrest AND rescue, the fall arrest load requirement applies).
- When more than one system is attached to an anchorage, the above anchorage strengths must be multiplied by the number of systems attached to the anchorage.
- Anchorage connector must be compatible with snap hook or carabiner and must not be capable of causing a load to be applied to the gate (keeper).
Limits of Use
- Self-Retracting Lifelines are designed for fall arrest applications only. Never use an SRL as a restraint or positioning device.
IMPORTANT!
- A fall restraint scenario could occur anytime
- The user fully extends the lifeline and applies weight or stress to that lifeline;
- The user intentionally or unintentionally locks up the lifeline, without the lifeline fully extended, and applies weight or stress to that lifeline.
- The correct application for using an SRL allows the user to be connected and move freely to perform the required work tasks without locking the lifeline or applying tension on the lifeline at full extension.
- Anchor device vertically overhead whenever possible. For the purposes of this instruc- tion manual, an overhead application implies that there is no slack in the lifeline when the unit is mounted above the user and connected to the user’s back D-ring.
- For suitability in other installation applica- tions, refer to section 4.0 Installation/Use.
- Never work above the device, unless instructions allow for such installation applications for your specific self-retracting lifeline model.
- Select Self-Retracting Lifelines/fall limiters may be used with Honeywell- approved horizontal lifeline systems. Always refer to the instructions provided with the horizontal lifeline system to determine if your Self-Retracting Lifelines model can be used with the system.
- The device should be installed and used in such a manner as to minimize the potential for a swing fall.
- Do not tie knots in lifelines, or wrap around sharp, rough edges, or small diameter structural members. Do not attach multiple connecting devices together, or attach a lanyard/lifeline back onto itself unless it is specifically designed for that purpose.
Connecting Devices
- Use only connecting devices containing locking snap hooks or locking carabiners.
- Connect in a manner that limits free fall to the shortest possible distance: 6ft (1.8 m) maximum.
- Always visually check that each snap hook and carabiner freely engages the harness D-ring or anchor point/anchorage connector, and that its gate (keeper) is completely closed and locked. Never disable or restrict locking keeper or alter connecting device in any way.
- Make sure snap hook/carabiner is positioned so that its gate is never load bearing.
- The use of shock absorbers is required to reduce fall arrest forces. All Miller shock absorbers, shock-absorbing lifelines, and Self-Retracting Lifelines limit maximum fall arrest forces to 1800 lb (8kN) or less.
- Never allow a lifeline to pass under or entwine around the user’s arms, legs, neck or any other obstacle.
Installation/Use
WARNING
- All Honeywell Miller Self-Retracting Lifelines must be inspected and tested for locking and retraction before each use (Ref. section 7.0 Inspection & Maintenance).
Typical Overhead Installation
(See Fig. B & C)
- Miller Self-Retracting Lifelines are typically mounted to an overhead anchorage by the anchorage attachment using a locking carabiner or other Honeywell-approved mounting device. (see 3.2 Anchorage requirements for more details)
- Always work directly under the anchor point to avoid a swing-fall injury.
- When selecting an anchorage point, always refer to the fall clearance calculation information provided with the connecting device to ensure that the anchorage point is at a height that will not allow a user to strike a lower level should a fall occur. Remember that shock absorbers will elongate when subjected to fall arrest forces (refer to the labels/instructions provided with the shock absorber for additional details).
- Review all warnings and instructions when selecting a mounting location. The device should be installed and used in such a manner as to minimize the potential for a swing fall.
- Refer to 2.2 Warnings and Limitations – Capacity
Horizontal Use
- Self-Retracting Lifelines shall be used for overhead use only, if they are classified as Class 1 (ANSI) or Class SRD (CSA). Self-retracting lifelines used for horizontal applications shall be classified as Class 2 (ANSI) or Class SRD-LE (CSA). Refer to the product label for application compliance.
- When installing a self-rotracting lifelines for horizontal use, special considerations and warnings apply. The following should be considered when mounting SRLs for horizontal use:
- Only use Edge (ANSI Class 2) models due to the likelihood of contact with sharp edges in this application
- Free fall distance may exceed 6ft
- Increased swing fall potential
- The locking speed of the SRL may vary in the event of a fall due to friction between the lifeline and the platform edge
- The SRL may lock up quicker than the workers walking pace and thus cause a fall by jerking the worker off balance
Self-Retracting Lifelines with Integral Rescue Capability
- MightEvac models shall be used with a maximum capacity of 310 lb (140.6 kg), including equipment and tools. The units are personal, meaning one person should be attached to one unit. Two people shall not attach to the same unit.
Inspect visual indicator
- The MightyLite and MightEvac units use a snaphook connector that indicate if the unit has been subjected to fall forces. Visually inspect the connector, if red appears, remove from service.
REMOVE FROM SERVICE IF RED APPEARS ****
MightEvac General Installation and Making Connections
- The MightEvac Self-Retracting Lifelines must be mounted to an overhead anchorage by the attachment swivel using a locking carabiner or other Miller approved anchorage connector, or it must be used in conjunction with a Miller mounting bracket which is then installed on a tripod, davit system, quad pod, or wall mount. The anchorage must be capable of supporting a 5,000 lb (22.2kN) tensile load or meet OSHA 1926.502 require- ments for a safety factor of two. Review all warnings and instructions when selecting a mounting location (see Fig. D).

Operation
Retrieval Operation
FOR EMERGENCY USE ONLY
- The MightEvac retrieval mechanism is to be used only in the event of an emergency. Do not use for routine hoisting of personnel or materials.
- NOTE: It is recommended to pull out several feet of lifeline and hold in position before engaging retrieval mechanism.
- Always maintain tension on the lifeline while in retrieval mode.
- Pull out on the plunger pin until the ratchet handle pops outward. It may be necessary to rotate the handle slightly to fully engage the internal gears. The plunger pin should snap back into its original position when the gears are fully engaged. The unit is now in retrieval mode.
- NOTE: A rescue may be executed either by raising or lowering a person to safety.
- TO RAISE: While maintaining light tension on the lifeline, rotate the ratchet handle counter-clockwise (CCW) to crank the lifeline into the housing.
- TO LOWER: To extend lifeline from the housing (to lower), rotate ratchet handle in clockwise (CW) direction.
- NOTE: If the internal braking mechanism has been activated, such as with a fall arrest, it is necessary to first crank in the counter clockwise (CCW) for one-half to one rotation, then reverse the direction (CW) to begin lowering. A minimum of 75 lb (34kg) is required for lowering.
WARNING
- Always ensure that the plunger pin has returned completely into the locked position when changing the unit from retractable to retrieval mode. Do not use the unit if it will not hold the load while in retrieval mode.
- Proper precautions should always be taken to remove any obstructions, debris, material, or other recognized hazards from the work area that could cause injuries or interfere with the operation of the system.
- The authorized person/user shall have a rescue plan and the means at hand to implement it when using this equipment. The Fall Protection rescue plan in place shall include methods on how to receive the individual when retrived to upper elevation that can include but is not limited to clearance between the subject and the retrival system, head protection PPE and rescue equipment suitable to the application.
Self-Retracting Lifelines Operation of MightEvac
- To return the unit to the retractable mode, remove the weight from the lifeline and secure the end of the lifeline as it will begin to retract once the internal gears are disengaged. Pull out on the plunger pin and hold. Push inward on the ratchet handle, where it connects to the gear shaft, to disengage the gears and return to retractable mode pull the plunger pin (see Fig. P).
Calculating
- Fall Clearance Distance
- It is essential to understand how to calculate the fall clearance distance required for each work application to avoid contact with a lower level.
- The basic calculation shown below and the related diagrams on pages 42 – 43 may be used to determine Required Fall Clearance when using Self-Retracting Lifelines in an overhead application. Refer also to Table 1: Minimum Required Fall Clearances.
SELF-RETRACTING LIFELINES FALL CLEARANCE CALCULATION
(See Fig. Q1-EN)
- [Calculation taken from work level]
- Maximum Arrest Distance (MAD)
- [Non-Standing Work Position Factor (NSF)]
- [Swing Fall Factor (SFF)]
- 3 ft (0.9 m) Safety Factor (SF)
- Required Fall Clearance (RFC)
- CAUTION: Read all notes and refer to all Self-Retracting Lifelines fall clearance diagrams and labels to determine the exact required fall clearance for your application.
IMPORTANT NOTES:
- Self-retracting lifelines must be anchored overhead to ensure the accuracy of the fall clearance calculation and related information.
- It is important to understand that other factors, such as whether the user is performing work in a standing, crouched, or lying down position and/or whether the user is working directly below the anchor point or at an angle, can affect fall distance when using a retractable device.
- The Self-Retracting Lifelines fall clearance calculation assumes the user is standing. If the user will be performing work in a crouched or kneeling position, an additional 3 ft (0,9m) of fall clearance is required (see Fig. Q2). If the user will be performing work in a lying down position, an additional 5 ft (1.5 m) of fall clearance is required.
- The Self-Retracting Lifelines fall clearance calculation also assumes the user is working directly below the anchor point, minimizing any possibility for a swing fall. In a swing fall situation, the total fall distance will be greater than if the user were working directly below the anchor point (see Fig. Q3).
- In some applications, it may not be possible to work directly below the anchor point. In such a case, the worker must increase the fall clearance distance to account for the swing fall factor. In any case, the worker must not be exposed to a potential swing fall where contact with another
- the object may occur (see Fig. Q4).

- This chart shows general minimum fall clearances required. An exact calculation, based on the SRL/Fall Limiter to be used and an assessment of the work site and conditions that may affect the worker’s fall clearance, must be performed.
- The maximum arrest distance [free fall (FF) + deceleration (D)] varies by retractable. Always refer to the labels on the specific unit to determine the maximum arrest distance.
- If a Self-Retracting Lifelines with a maximum arrest distance of less than 42 in (1.06 m) – ANSI- and 47 in (1.4 m) -CSA
- has been approved for (by Honeywell) and is being used in a non-overhead application, the maximum arrest distance allowed per standards – 42 in (1.06 m)
- ANSI- and 47 in (1.4 m) -CSA -must be used when calculating fall clearance distance; wheter the user is between the 130 lb – 310 lb (59 kg – 140.6 kg).
- If there is any question about calculating fall clearance distance, please contact Honeywell Technical Service: 800-873-5242 (press 4)
Free Fall
- Personal fall arrest systems must be rigged to limit a free fall to the shortest possible distance: 6 ft (1.8 m) maximum.
Inspection and Maintenance
Inspection and Operation Testing
-
Honeywell Safety Products’ inspection requirements incorporate the criteria established by current safety standards. The inspection criteria for the equipment
-
shall be set by the user’s organization, such that it equals or exceeds the criteria required by the manufacturer and the standards with which the organization elects to comply.
-
Equipment shall be thoroughly inspected and operationally tested by the user before each use, and additionally, by a competent person, other than the user, at regular intervals of no more than one year. If any of the following conditions is observed removed from service:
-
Absence or illegibility of markings/labels
-
Absence of any elements affecting the equipment form, fit or function
-
Evidence of defects in or damage to the cable or webbing lifeline including fraying, cuts, broken strands, burns, corrosion, kinks, chemical attack, abrasion, altera- tion, excessive aging, excessive wear, and loose, broken or pulled stitches
-
Operational damage to the lifeline
-
Evidence of defects in or damage to hardware elements including cracks, breaks, rough or sharp edges, deforma- tion, corrosion, chemical attack, exces- sive heating, pitted surfaces, alteration, and excessive wear
-
Operational damage to the hardware
-
Evidence of defects in or damage to the housing and/or loose/missing fasteners
-
Evidence of deployed or activated fall load indicators
-
Failure to lock when the lifeline is pulled out rapidly, so as to simulate a fall arrest
-
ANSI Z359.14-2021 and CSA Z259.2.2 – provide additional inspection requirements based on type of use and conditions of use. Refer to ANSI Z359.14-2021: “6.1 Inspection” and CSA Z259.2.2: Table 2 “Inspection and revalidation”. (*See note in section 5.2 Maintenance.)
-
CAUTION: Always wear gloves when inspecting cable lifelines; broken strands can cause injury!
-
Snap Hook/Carabiner – The connector gate (keeper) should seat into the nose without binding and should not be distorted or obstructed. The gate spring should exert sufficient force to firmly close the gate. The gate locking mechanism must prevent the gate from opening when closed.
Retraction – With the device in a mounted position, test the lifeline retraction and tension by pulling out several feet of the lifeline and allow to retract back into the unit. Always maintain a light tension on the lifeline as it retracts. The lifeline should pull out freely and retract all the way back into the unit. If the lifeline does not pull out smoothly or sticks when retracting, pull all the lifeline out of the housing and allow it to retract slowly under tension. Do not use the unit if the lifeline does not retract properly. -
CAUTION: Do not let go of the lifeline and let it retract on its own; always main- tain tension while it retracts!
-
Lockup Mechanism – The braking mechanism can be tested by grasping the lifeline ABOVE the load indicator and applying a sharp steady pull downward which will engage the brakes. There should be no slippage of the lifeline while the brake engages. Once tension is released, the brakes will disengage and the unit will return to the retractable mode.
-
Swivels – The connector and anchorage swivels should operate smoothly.
WARNING
- When inspection and operational testing reveals defects in or dam- age to equipment, inadequate main- tenance of equipment, or evidence of equipment having been exposed to fall arrest forces or loading, the equipment shall be immediately re- moved from service. Units removed from service, shall be marked and tagged “UNUSABLE” and returned for service in accordance with the manufacturer’s instructions. Non- repairable devices must be disposed of in a manner to prevent inadver- tent further use.
- Every Honeywell Miller MightyLite or MightEvac will be equipped with the following load impact indicator:
Snap Hook Load Indicator (See Fig. R)
- The snap hook load impact indicator is built into the swivel part of the snap hook. The swivel eye will elongate and expose a red area at the location illustrated when subjected to fall arrest forces (Refer to 4.4 Inspect visual indicator).
Maintenance
- Basic care of all fall protection equipment will prolong its service life and will contribute toward the performance of its vital safety function.
Servicing
- Servicing of Honeywell Miller Self-Retracting Lifelines must only be carried out by Honeywell Safety Products or persons or entities authorized in writing by Honeywell. A record log of all servicing and inspection dates for this device must be maintained. Only original Honeywell replacement parts are approved for use in this device. Contact your Honeywell distributor or call Honeywell Technical Service at 800-873-5242 for a return authorization number.
- Honeywell Miller Self-Retracting Lifelines (included in this manual) requires no annual factory recertification for Honeywell Miller. ANSI Z359.14-2021 and CSA Z259.2.2 standards are voluntary; and ultimately, the end-user/company must elect to follow the inspection and recertification requirements if it is to be compliant with the standard.
Cleaning and Storage
- This device must be kept clean and free of contaminants. Periodically clean the exterior of the device and wipe the lifeline using a damp cloth and mild detergent.
- When not in use, equipment shall be stored in a manner as to preclude damage from environmental factors, such as temperature, light, UV, excessive moisture, oil, chemicals, vapors, or other degrading elements.
- The lifeline should be fully retracted into the device when not in use.
