1.0 PRODUCT APPLICATION
1.1 PURPOSE: The DBI-SALA Climb Assist/Fall Arrest System is a component used in a personal fall arrest system (PFAS).
This equipment is to be used in situations where worker mobility and fall protection is needed (inspection work, general
construction, maintenance work, oil production, confined space work, etc.). The DBI-SALA Climb Assist/Fall Arrest System
can also provide assistance in climbing fixed ladders.
Normal operation will allow the full length of the lifeline to extend and retract as the worker moves. If a fall occurs, the
locking pawls will engage into the grooves (or teeth), stopping the fall. The cable will slide on the drum a limited distance
to absorb much of the energy created in the fall. If a fall has been arrested, the Climb Assist/Fall Arrest System must be
taken out of service and inspected. See Section 5.
1.2 STANDARDS: Your DBI-SALA Climb Assist/Fall Arrest System conforms to the national or regional standard(s) identified
on the front cover or Table 1 of these instructions. If this product is resold outside of the original country of destination,
the re-seller must provide these instructions in the language of the country where the product will be used.
1.3 SUPERVISION: Use of this equipment must be supervised by a Competent Person¹.
1.4 LIMITATIONS: Always consider the following limitations when using the DBI-SALA Climb Assist/Fall Arrest System:
• Anchorage: Structure on which the DBI-SALA Climb Assist/Fall Arrest System is mounted must meet the Anchorage
specifications defined in Table 1.
• Fall Path and Locking Speed: A clear path is required to assure positive locking of a Climb Assist/Fall Arrest
System. 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 Climb Assist/Fall Arrest System 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 Climb Assist/Fall Arrest System to lock.
• Fall Clearance: Ensure adequate clearance exists in your fall path to prevent stricking an object. A minimum of 6
feet from the working level to the lower level or nearest obstruction is recommended.
• 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. 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 the total free fall distance
and the area required to safely arrest the user. In order to minimize wear and friction between the lifeline and the
cable bushing on the housing and to decrease swing fall hazards, DBI-SALA recommends your work zone be within
5° of the anchorage point. Minimize swing falls by working as directly below the anchorage point as possible. Never
permit a swing fall if injury could occur. If a swing fall situation exists in your application contact DBI-SALA before
proceeding.
• Sharp Edges: The DBI-SALA Climb Assist/Fall Arrest System must be installed so deflection of the anchor line in a
fall arrest does not bring the anchor line into contact with a sharp edge or any other article that may damage the
anchor line.
Avoid working where Lifeline or Lanyard components of the attached Personal Fall Arrest System (PFAS) can contact
or abrade against unprotected sharp edges. Where contact with a sharp edge is unavoidable, cover the edge with
protective material.
2.0 SYSTEM CONSIDERATIONS
2.1 RESCUE PLAN: When using this equipment and connecting subsystem(s), the employer must have a rescue plan and
the means at hand to implement and communicate that plan to users, authorized persons
2
, and rescuers
3
. A trained, on-
site rescue team is recommended. Team members should be provided with the equipment and techniques to perform a
successful rescue. Training should be provided on a periodic basis to ensure rescuer proficiency.
2.2 INSPECTION FREQUENCY: The DBI-SALA Climb Assist/Fall Arrest System shall be inspected by the user before each
use. Additionally, a Periodic Examination should be performed by a Competent Person or Certified Installer⁵ at intervals
of no more than one year
4
. Inspection procedures are described in the “Inspection and Maintenance Log” included in
these instructions. Results of each Competent Person or Certified Installer Inspection should be recorded on copies of the
Inspection and Maintenance Log .
2.3 AFTER A FALL: If the Climb Assist/Fall Arrest is subjected to the forces of arresting a fall, it must be removed from the
field of service immediately and inspected per Section 5.
2.4 PERSONAL FALL ARREST SYSTEM: Figure 1 illustrates typical Fall Arrest applications of this DBI-SALA
Climb Assist/Fall Arrest System. Personal Fall Arrest Systems (PFAS) used with the system must meet applicable Fall
Protection standards, codes, and requirements. The PFAS shall incorporate a Full Body Harness and limit Maximum
Arresting Force (MAF) to 1,800 lbs (8 kN) and Total Arrest Distance to 42 inches (1.06 m).
2.5 COMPONENT COMPATIBILITY: 3M FALL Protection equipment is designed for use with 3M approved components and
subsystems only. Substitutions or replacements made with non-approved components or subsystems may jeopardize
compatibility of equipment and may effect the safety and reliability of the complete system.
1 Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which is unsanitary, hazardous, or
dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
2 Authorized Person: A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard.
3 Rescuer: Person or persons other than the rescue subect acting to perform an assisted rescue by operation of a rescue system.
4 Inspection Frequency: Extreme working conditions (harsh environments, prolonged use, etc.) may require increasing the frequency of Periodic Examinations.
5 Certified Installer: A person certified by 3M with extensive knowledge, training, and experience in the fall protection and rescue field who is capable of designing,
analyzing, evaluating, and specifying fall protection and rescue systems to the extent required by applicable regional and national standards.
