Rescue: The structure to which rescue system is attached must sustain static loads applied in
the directions permitted by the work positioning system of at least 3,000 lbs., or five times the
potential impact load, whichever is greater. See OSHA1926.502. When more than one work
positioning system is attached to an anchorage, the strengths stated above must be multiplied
by the number of work positioning systems attached to the anchorage.

Non-Certified Anchorage
5,000 lbs (22.2kN)
Multiple Systems: When more than one of the
defined systems is attached to an anchorage, the
strength defined shall be multiplied by the
number of systems attached to the anchorage.

Certified Anchorage: An anchorage for Personal
Fall Arrest, Work Positioning, Restraint or Rescue
systems that a qualified person certified to be
capable of supporting the potential fall or that
meets the criteria for a certified anchorage point,
as prescribed by relevant ANSI and OSHA
standards.

Free Fall:
Maximum free fall distance allowed for use in a Personal Fall Arrest System is 6 ft. For use in a
Restraint or Rescue System, no Free Fall is permitted. For use in a Work Positioning System,
maximum free fall distance allowed is 2 ft. Do not work above the anchorage level to avoid increased
Free Fall Distance.
Fall Arrest Forces:
The Personal Fall Arrest System must limit fall arrest forces to 900 lbs. (4kN). Deceleration distance
shall not be allowed to exceed 42 in.
Swing Falls:
Minimize swing fall by working as directly below the anchorage point as possible. Do not permit a
swing fall if injury could occur.
Fall Clearance:
Consider the following when calculating fall
clearance. Clearance required is dependent
on the following factors:
•
Elevation of Anchorage
•
Connecting Subsystem Length
•
Deceleration Distance
•
Free Fall Distance
•
Worker Height
•
D-ring / connector length
•
Movement of Harness Attachment Element
•
Length of Full Body Harness (FBH) Stretch
•
Working Level
