time during use. The following list gives some important points to
consider when planning your system:
1. ANCHORAGE: Select an anchorage point that is rigid and
capable of supporting the required loads. Locate the roof anchor
in accordance with Section II.
2. PERSONAL FALL ARREST SYSTEM REQUIREMENT: PFAS's
used with this roof anchor must meet applicable OSHA, state,
federal, and ANSI requirements. PFAS's incorporating a full
body harness must be capable of arresting a worker's fall
with maximum arresting force of no greater than 900 lbs. and
limiting the free fall distance to 6 feet or less. Reference OSHA
requirements.
3. FREE FALL: PFAS's must be rigged to limit any free fall to a
maximum of 6 feet (OSHA). Restraint systems must be rigged
such that no vertical free fall is possible. Avoid working above
your anchorage level since an increased free fall distance will
result.
4. RESTRAINT SYSTEMS:
applicable state and federal requirements.
5. FALL CLEARANCE: Should a fall occur, there must be sufficient
clearance in the fall area to arrest the fall before striking the
ground or other objects. The actual clearance required is
dependent upon the type of fall arrest connecting subsystem
used (energy absorbing lanyard, self retracting lifeline, etc.).
Refer to manufacturer's instructions for fall clearance information.
