1.0 APPLICATION
1.1
PURPOSE: Sealed-Blok™ Self Retracting Lifelines (SRLs) are designed to be a component in a personal fall
arrest system (PFAS). 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, confi ned
space work, etc.). Some Sealed-Blok™ SRL models incorporate a built-in retrieval feature. These models
have the same fall arrest capabilities as those described above when used in their non-retrieval mode.
In the retrieval mode these models may be used for emergency rescue (raising or lowering) of personnel
within the capacity range stated below. It is also permissible to use retrieval models for raising and lowering
of materials within the stated capacity range. Other Sealed-Blok™ SRL models include the DBI-SALA RSQ
controlled descent feature for self-rescue/descent or assisted rescue. See Capital Safety manual 5903060
(Sealed-Blok™ Self Retracting Lifeline with Retrieval) and 5903061 (Sealed-Blok™ RSQ Controlled Descent
Self Retracting Lifeline).
IMPORTANT: This equipment may not be suitable for applications requiring frequent or continual use as a
material hoist. Consult Capital Safety before using this product for such applications. The retrieval models
listed above are not designed to be used for general purpose work positioning or man-riding applications.

STANDARDS: Refer to local, state, and federal (OSHA) requirements governing occupational safety for
additional information regarding Personal Fall Arrest Systems. Refer to the following national standards on fall
protection:

Z359.1
ANSI
Z359.2
ANSI
Z359.4
CSA
Z259.2.2-98
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.
2.0 SYSTEM LIMITATIONS & REQUIREMENTS
Always consider the following limitations/requirements when installing or using this equipment:
2.1
CAPACITY: Sealed-Blok™ SRLs are designed for use by persons with a combined weight (person, clothing,
tools, etc.) of 75 lbs. to 310 lbs per ANSI Z359. Some units have a capacity of 420 lbs. per OSHA. Refer to
the instruction label to determine the capacity of your unit. At no time shall more than one person connect
to a single SRL for fall arrest applications.
2.2
ANCHORAGE: Select a rigid anchorage point that meets strength requirements for Fall Arrest and Rescue
systems. In accordance with ANSI Z359.1, anchorages selected must have a strength capable of sustaining static
loads applied in the directions permitted by the system of at least:
Fall Arrest Applications:
Rescue Applications:
NOTE: When more than one rescue system is attached to an anchorage, the strengths set forth above shall be
multiplied by the number of systems attached to the anchorage.
2.3
RESCUE PLAN: When using this equipment, the employer must have a rescue plan and the means at hand
to implement it and communicate that plan to users, authorized persons, and rescuers.
2.4
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 SRL 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 SRL to lock. A clear path is required to assure positive locking of the SRL.
2.5
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 and absorbing much of the
energy created. For falls which occur near the end of the lifeline travel, a reserve lifeline system has been
incorporated to assure a reduced impact fall arrest. If a fall has been arrested, the SRL must be taken out of
service and inspected (see Section 5). Sudden or quick movements should be avoided during normal work
operation, as this may cause the SRL to lock up.
