FP Pro Vest Style Harness
P/N 623244, Rev. D
6.2.2 COMPATIBILITY OF CONNECTORS
Connectors, such as D-rings, snaphooks, and carabiners, must be rated at 5,000 lbf (22 kN) minimum
breaking strength. MSA connectors meet this requirement. Connecting hardware must be compatible in size,
shape, and strength. Non-compatible connectors may accidentally disengage (“rollout”). Always verify that
the connecting snaphook or carabiner and the D-ring on the harness or anchorage connector are compatible.
Use only self-closing, self-locking snaphooks and carabiners with the FP Pro Harness.
6.2.3 ANCHORAGES AND ANCHORAGE CONNECTORS
Anchorages for personal fall arrest systems must have a strength capable of supporting a static load, applied
in directions permitted by the system, of at least: (a) 3,600 lbf (16 kN) when certification exists, or (b) 5,000
lbf (22.2 kN) in the absence of certification. When more than one personal fall arrest system is attached to an
anchorage, the anchorage strengths set forth in (a) and (b) must be multiplied by the number of systems
attached to the anchorage. This requirement is consistent with OSHA requirements under 29 CFR 1910,
Subpart F, Section 1910.66, Appendix C.
7.0 PLANNING THE USE OF SYSTEMS
Perform the hazard identification and evaluation described in section 3 of these instructions. Then plan the
system(s) before starting work. Consider all possible paths of user movement and all factors that could affect
the user’s safety before, during, and after a fall anywhere along these paths. A qualified person must select
the components, materials, anchorage and anchorage connectors to match the system application, the
work, workplace hazards, and the environment. Consider the following points when planning the system(s).
7.1 ANCHORAGE AND ANCHORAGE CONNECTOR SELECTION
Determine the necessary locations of anchorages to assure that the user will be continuously connected
when exposed to hazards of falling. Select anchorages that are stable and have the strength required by
section 6.2.3 of these instructions. Carefully select the locations of the anchorages to: (a) reduce possible
free fall distance, (b) prevent swing fall hazards, and (c) provide clear space in the potential fall paths to avoid
striking an object. Do not select anchorage locations that will require the user to work above them as this will
increase the potential free fall and total fall distances. Plan the types of anchorage connectors that will need
to be selected and refer to the instructions for same.
7.2 FREE FALL DISTANCE, TOTAL FALL DISTANCE AND SYSTEM
ELONGATION
Personal fall arrest systems must be selected and rigged to ensure that potential free fall distances will never
exceed 6 ft (1.8 m) as required by OSHA. ANSI A10.14 restricts free fall distance to 5 ft (1.5 m)]. See
separate instructions for connecting subsystems to determine the deceleration distance and dynamic
elongation which must be allowed for in the space of potential fall paths. Total fall distance is the sum of free
fall distance and deceleration distance. Dynamic elongation of the system (temporary elastic stretch of
connecting components and subsystems) must be added to total fall distance and clearance allowed.
