Fall Clearance:
There must be
sufficient clearance below the
anchorage connector to arrest
a fall before the user strikes
the ground or an obstruction.
When calculating fall clearance,
account for a MINIMUM 3’
safety factor, deceleration
distance, user height, length
of lanyard/SRL, and all other
applicable factors.
