1.0 APPLICATIONS
1.1 PURPOSE: Self-Retracting Devices (SRDs) are designed to be a component in a personal fall arrest system (PFAS). Figure
1 illustrates SRDs covered by this instruction manual. They may be used in most situations where a combination of worker
mobility and fall protection is required (i.e. inspection work, general construction, maintenance work, oil production,
confined space work, etc.).
1.2 STANDARDS: Your SRD conforms to the national or regional standard(s) identified on the front cover of these
instructions. Refer to the local, state, and federal (OSHA) requirements governing occupational safety for additional
information regarding Personal Fall Protection.
1.3 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 assure they are familiar with these instructions and are trained in the correct care and use
of this equipment. Users must also be aware of the operating characteristics, application limits, and the consequences of
improper use.
1.4 LIMITATIONS: Always consider the following limitations when installing or using this equipment:
• Capacity: Per ANSI Z359.14 requirements, SRDs are for use by one person with a combined weight (clothing,
tools, etc.) from 130 lbs (59 kg) to 310 lbs (141 kg).

Make sure all of the components in your system are rated to a
capacity appropriate to your application.
• 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:
1. 5,000 lbf (22.2 kN) for non-certified anchorages, or
2. Two times the maximum arresting force for certified anchorages.
When more than one fall arrest system is attached to an anchorage, the strengths set forth in (1) and (2) above shall
be multiplied by the number of systems attached to the anchorage.
FROM OSHA 1926.502 AND 1910.140: 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.
per user attached, or be designed, installed, and used as part of a complete personal fall arrest systems which maintains
a safety factor of at least two, and is under the supervision of a qualified person.
• Locking Speed: Situations which do not allow for an unobstructed fall path should be avoided. Working in confined
or cramped spaces may not allow the body to reach sufficient speed to cause the SRD to lock if a fall occurs. Working
on slowly shifting material, such as sand or grain, may not allow enough speed buildup to cause the SRD to lock. A
clear path is required to assure positive locking of the SRD.
• Free Fall: When used correctly, SRDs will limit the free fall distance to 2 ft. (61 cm). To avoid increased fall distances,
do not work above the anchorage level. Do not lengthen SRDs by connecting a lanyard or similar component without
consulting 3M. Never clamp, knot, or prevent the lifeline from retracting or being taut. Avoid slack line.
• Swing Falls: Swing Falls occur when the anchorage point is not directly above the point where a fall occurs. The
force of striking an object in a swing fall may cause serious injury (see Figure 3A). Minimize swing falls by working as
directly below the anchorage point as possible.
• Fall Clearance: Figures 3B and 3C illustrate Fall Clearance. SRD Fall Arrest Systems should have a minimum Fall Clearance
of 6 ft (2 m) for falls from a standing position where the SRD is anchored directly overhead (Figure 3B). Falls from a
kneeling or crouching position will require an additional 3 ft (1 m) of Fall Clearance. In swing fall situations (Figure 3C),
the total vertical fall distance will be greater than if the user had fallen directly below the anchorage point and requires
additional Fall Clearance. Figure 4 and the accompanying table defi ne the Maximum Work Radius (C) for various SRD
Anchorage Heights (A) and Fall Clearances (B). The Recommended Work Zone is limited to the area located within the
Maximum Work Radius.
• 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, or overhead materials that may fall and contact the user or fall arrest system. 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.
• Sharp Edges: Avoid working where the lifeline will be in contact with or abrade against unprotected sharp edges. Where
contact with a sharp edge is unavoidable, cover the edge with a protective material.
1 Capacity:
130 lbs -310 lbs (59 kg- 141 kg) is the capacity range required by standard ANSI Z359.14 Class B. Some SRDs also support a 420
lbs (191 kg) Maximum Capacity per OSHA. See Figure 1 for the SRD models covered by this instruction and their Maximum Capacities.
