it and communicate that plan to users, authorized persons, and rescuers.
i
Special rescue measures may be required for a fall over an edge.
2.5 INSPECTION FREQUENCY: SRLs shall be inspected by the user (authorized person
Table 1 before each use. Additionally, inspections shall be conducted at least annually by a competent person
the user. The competent person shall use the Nano-Lok Edge Self Retracting Lanyards Inspection Schedule and Checklist
(Table 1) for appropriate inspection intervals and procedures. Results of the Competent Person inspection should be
recorded in the "Corrective Action/Maintenance Log" in these instructions or recorded with the i-Safe™ system (see Section
5).
2.6 LOCKING SPEED: Situations which restrict the speed of a fall must be avoided when using SRLs. Do not working in
confined or cramped spaces that may not allow the body to reach sufficient speed to cause the SRL to lock if a fall occurs.
Do not work on slowly shifting material, such as sand or grain, which may not allow enough speed buildup to cause the
SRL to lock. A clear path is required to assure positive locking of the SRL.
2.7 NORMAL OPERATIONS: Normal operation will allow the full length of the lifeline to extend and retract with no hesitation
when extending and no slack when retracting as the worker moves at normal speeds. If a fall occurs, a speed sensing
brake system will activate, stopping the fall. An external energy absorber will activate during fall arrest to absorb much
of the energy created and reduce impact forces. Sudden or quick movements should be avoided during normal work
operation, as this may cause the SRL to lock up.
2.8 FREE FALL: When anchored overhead, SRLs will limit the free fall distance to 0.6 m or less. To avoid increased fall distances,
anchor the SRL directly above the worker. Avoid working where your lifeline may cross or tangle with that of another worker.
Avoid working where an object may fall and strike the lifeline, resulting in loss of balance or damage to the lifeline. Do not
allow the lifeline to pass under arms or between legs. Never clamp, knot, or prevent the lifeline from retracting or being
taut. Avoid slack line. Do not lengthen SRL by connecting a lanyard or similar component.
2.9 HAZARDS: Use of this equipment in areas where surrounding hazards exist may require additional precautions to reduce
the possibility of injury to the user or damage to the equipment. Hazards may include, but are not limited to: high heat,
caustic chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp
edges, or overhead materials that may fall and contact the user or fall arrest system.
2.10 SHARP EDGES, TYPE A AND B: The Nano-Lok Edge Self Retracting Lanyard has been successfully tested for horizontal
use and for falls over a steel edge without burrs. Setback distance restrictions shown in Figures 7 and 8 must be
observed. Avoid working where the lifeline will continuously or repeatedly abrade against sharp or abrasive edges.
Eliminate such contact or protect edges using a heavy pad or other means.
Models C, D, E and F meet the test requirements of the VG 11.60 revision 6 Sharp Edge Type A.
Type A Edge Defi nition: A steel edge with a radius of r=0,5 mm and without burrs was used for the test. Due to
i
this test, the equipment may be used over similar edges, as can be found e.g. at rolled steel profi les, at wooden
beams or at a clad, rounded roof parapet.
Models A and B meet the test requirements of the VG 11.54 revision 6 Extremely Sharp Edge Type B.
Type B Edge Defi nition: A steel edge made of a sharp-edged drawn square steel bar in accordance with EN
i
10278:1999-12 without radii (material C 45+C or E 335 GC (ST60) pursuant to EN 10025). Due to this test, the
equipment may be used over similar edges, as can be found e.g. trapezoidal sheet metal.
WARNING: The allowable angle of redirection of the lifeline at the edge over which a fall might occur (see
Figures 3A, B and C.), measured between the two sides formed by the redirected lifeline (B in Figures 7 and 8),
must be at least 90 degrees. In other words, working above the level at which the SRL is anchored (example:
Figure 3C) and being exposed to an edge hazard is dangerous because this will cause the lifeline to "redirect"
at a sharper angle if a fall occurs and may cut or damage the lifeline. Failure to heed this warning may result in
serious injury or death.
Do not work on the far side of an opening, opposite the SRL anchorage point. Failure to heed this
warning may result in serious injury or death.

2.11 BODY SUPPORT: A Full Body Harness must be used with the SRL. The harness connection point must be above the user's
center of gravity just below the harness back dorsal D-Ring. A body belt is not authorized for use with the Nano-Lok Edge
SRL. A fall occurring when using a body belt may cause unintentional release and/or injuries due to improper body support.
2.12 SWING FALLS: Swing falls occur when the anchorage point is not directly above the point where a fall occurs (see
Figure 4). The force of striking an object in a swing fall may cause serious injury. In a swing fall, the total vertical fall
distance will be greater than if the user had fallen directly below the anchorage point, thus increasing fall clearance
required to safely arrest the user. (See Section 4.4) Minimize swing falls by working as directly below or adjacent to the
anchorage point as possible. Never permit a swing fall if injury could occur.
Ensure adequate clearance exists in the fall path to prevent striking an object during a fall.
1 Authorized Person:
A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard.
2 Rescuer:
Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
3 Competent Person:
An individual designated by the employer to be responsible for the immediate supervision, implementation, and monitoring of the employ-
er's managed fall protection program who, through training and knowledge, is capable of identifying, evaluating, and addressing existing and potential fall hazards,
and who has the employer's authority to take prompt corrective action with regard to such hazards.
4 Setback Distance:
The minimum distance the SRL must be anchored back from the edge or fall hazard.
