Fall Clearance; Compatibility Of Components, Connectors, And Subsystems - MSA Stanchion Mode D'emploi

1.5.3 Fall Clearance

Make sure that there is sufficient clearance in the fall path to prevent collisions with objects during a fall. Fall
clearance is calculated from the type and length of the connecting subsystem (rope grab, lanyard), number
of users, anchorage location, and span length of the HLL. Stanchion deflection must also be considered
when determining fall clearance. Refer to the Lifeline instructions for its required clearance then add the
stanchion clearance from the chart below.

1.5.4 Compatibility of Components, Connectors, and Subsystems

Use only compatible MSA components, connectors, and subsystems with this MSA equipment. Make sure
that connectors are compatible with the anchorage and other system components. Make sure that connec-
tors are compatible in size, shape, and strength. Use only self-locking snap hooks and carabiners to meet
the requirements of ANSI Z359.12 and OSHA. Connectors that are not compatible can accidentally disen-
gage. Make sure that all compatible hooks, carabiners, and D-rings can give support for at least 5,000 lbf
(22 kN).
Use an MSA full-body harness and connecting sub-systems with the HLL system.
