1. ANCHORAGE: Select a rigid anchorage point that is capable of
supporting the required loads. See section II.b.
The anchorage location must be carefully selected to reduce
possible free fall and swing fall hazards and to avoid striking an
object during a fall. For restraint systems the anchorage must be
located such that no vertical free fall is possible. For fall arrest
systems OSHA requires the anchorage be independent of the
means suspending or supporting the user.
2. FREE FALL: Do not work above the anchorage level, increased
fall distance will result. Personal fall arrest systems must be
rigged such that the potential free fall is never greater than six
feet. Restraint systems must be rigged such that there is no
possible vertical free fall.
3. FALL ARREST FORCES: The assembled fall arrest system
must keep fall arrest forces below 1,800 lbs. when used with a
full body harness. Do not use a body belt for fall arrest.
4. SWING FALLS: Swing falls
occur when the anchor is
not directly above the point
where a fall occurs. The
force of striking an object
while swinging can be great
and cause serious injury.
Minimize swing falls by
working as directly below the
anchorage as possible (the
worker must be positioned
within 30 degrees of the
roof anchor). It is acceptable
to captivate a lifeline (i.e.
rope grab system) to an
anchorage close to the work
area with a carabiner. Do
not captivate the lifeline of a
self retracting lifeline as this may affect the performance of its
internal braking.
5. FALL CLEARANCE: Make certain enough clearance exists
in your fall path to prevent striking an object. The amount of
clearance needed is dependent upon the type of connecting
subsystem used and anchorage location.
