WARNING!
Do NOT change the design or configuration of the MSA stanchion. Use only exact replacement parts in the
configuration specified by MSA. Do NOT make unauthorized repairs, modifications, or additions to this
product.
The beam or concrete to which the stanchion is attached must be able to supply support for the Anchor Load
(AL) and Anchor Moment (AM) limits specified in Figures 4 and 6 during a fall arrest. When more than one
system is installed on a beam or concrete, the beam or concrete must be able to supply support for the
cumulative Anchor load (AL) and Anchor moment (AM) of the total number of systems.
Be careful when you lift or move the stanchions. The beam clamp assembly can disconnect from the stan-
chion base.
Before installation starts, make sure that the fall clearance is sufficient.
During installation and removal of the stanchion and HLL system, prevent exposure to fall hazards. If neces-
sary, use an aerial work platform. During installation and removal of the stanchion and HLL system at height,
take necessary precautions to prevent stanchion and HLL system components from falling from height.
Remove any surface contamination (such as, but not limited to, concrete, stucco, roofing material) that can
prevent correct attachment of the stanchion to the beam.
Failure to obey these warnings can result in serious injury or death.
HLL System Height, Elevation, and Slope
Install the stanchions at a location that limits user free fall distance to 6 ft (1.8 m). Install both stanchions at
approximately the same elevation. Make sure that the slope of the HLL is 5 degrees or less. Make sure that
the HLL is straight and horizontal, and does not have turns or bends.
