1.0 APPLICATIONS
1.1 PURPOSE: DBI-SALA
Full Body Harness and Fall Arrest Equipment such as a Lanyard or Self-Retracting Device. The Self-Rescue System
allows the user to descend from a suspended height in an emergency. Figure 1 defines available Self-Rescue
models and their capabilities.
1.2 STANDARDS: This Self-Rescue System conforms to the national or regional standard(s) identified on the front cover of
these instructions.
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. The Self-Rescue TRAINING System can be used to train personnel in the use of the Self-Rescue System
(see Appendix A)
1.4 LIMITATIONS: In addition to the limitations defined in the manufacturer instructions for the Full Body Harness and Fall
Arrest Equipment, always consider the following limitations when installing or using the Self-Rescue System:
!
WARNING: Failure to observe the following restrictions may result in injury or death.
• Capacity: The Self-Rescue System has been compliance tested 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 the system are
rated to a capacity appropriate to the application.
• Anchorage Strength: Anchorages suspending the Self-Rescue System shall have a strength capable of
sustaining static loads applied in the directions permitted by the system of at least: 5,000 lbs. (22.2 kN) for non-
certified anchorages, or two times the maximum arresting force for certified anchorages.
• Maximum Number of Descents: The Self-Rescue 50 and Self-Rescue 100 Systems are single-descent devices.
After a descent, remove the Self-Rescue System from service and contact 3M regarding repair.
L IMPORTANT: Only 3M or parties authorized in writing may make repairs to this equipment.
L SeLf-ReSCue TRAINING SySTeM: The Self-Rescue TRAINING System can be used for up to 20
descents in a controlled training environment with secondary fall protection (see Appendix A).
• Maximum Descent Speed: Per ANSI Z359.4, Maximum Descent Speed of the Self-Rescue System shall not
exceed 6.6 ft/s (2 m/s). Descent Speed will vary with the weight of the user. See the Figure 1 performance
specifications for the "Approximate Descent Speed".
• 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
Self-Rescue 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 Self-Rescue Lifeline will be in contact with or abrade against unprotected
sharp edges. Where contact with a sharp edge is unavoidable, cover the edge with abrasion resistant material.
2.0 uSe
2.1 FALL PROTECTION AND RESCUE PLAN: The employer must have a Fall Protection and Rescue Plan in place that
meets ANSI Z359.2 Minimum Requirements for a Comprehensive Managed Fall Protection Program. The plan
should provide guidelines and requirements for an employer's managed fall protection program, including policies,
duties and training; fall protection procedures; eliminating and controlling fall hazards; rescue procedures;
incident investigations; and evaluating program effectiveness.
2.2 INSPECTION FREQUENCY: The Self-Rescue 50 and Self-Rescue 100 Systems must be inspected by an Authorized
Person or Rescuer
1 2
other than the user. Extreme working conditions may necessitate more frequent Competent Person inspections.
The Self-Rescue TRAINING System shall be inspected by a Competent Person before each use. The Competent
Person shall use the Inspection Schedule (Table 1) to determine appropriate inspection intervals. Inspection
procedures are described in the "Inspection Checklist" (Table 2). Results of the Competent Person inspection should
be recorded in the "Inspection and Maintenance Log" on the back pages of these instructions or recorded with the
i-Safe™ system (see Section 5).
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 employer'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.
