2.2 Component Warnings and Limitations
ANCHORAGES
• Anchorages must be capable of supporting 5,000 pounds (22.2kN) per worker or meet OSHA
1926.502 requirements for a safety factor of two.
• Anchorage requirements based on ANSI are as follows:
• For fall arrest systems, anchorages must withstand a static load of 5,000 lbs. (22.2kN) for non-certified
anchorages or two times the maximum arresting force for certified anchorages.
• For positioning systems, anchorages must withstand a static load of 3,000 lbs. (13.3kN) for non-certified
anchorages or two times the foreseeable force for certified anchorages.
• For travel restraint, anchorages must withstand a static load of 1,000 lbs. (4.5kN) for non-certified
anchorages or two times the foreseeable force for certified anchorages.
• For rescue systems, anchorages must withstand a static load of 3,000 lbs. (13.3kN) for non-certified
anchorages or five-times the applied load for certified anchorages.
• When more than one personal fall arrest system is attached to an anchorage, the above anchorage strengths
must be multiplied by the number of personal fall arrest systems attached to the anchorage.
• Always work directly under the anchor point to avoid a swing-fall injury.
• Ensure that the anchorage connector is at a height that will not allow a lower level to be struck should
a fall occur. When selecting an anchorage point, always remember that shock absorbers will elongate
when subjected to fall arrest forces. Refer to the labels and instructions provided with the connecting
device to obtain the maximum elongation distance. This maximum elongation distance must be
considered when choosing an anchor point.
• Ensure that the anchor point is at a height that limits free fall distance to 6 feet (1.8m) or less.
• Anchorage connector must be compatible with snap hook or carabiner and must not be capable of
causing a load to be applied to the keeper.
• Never use an anchorage connector which will not allow snap hook or carabiner keeper to close.
BODY WEAR
• Visually check all buckles to assure proper and secure connections before each use. All straps
must be connected and adjusted to provide a snug fit.
• Fall protection connecting devices should be attached to the back D-ring of a full-body harness. A
front D-ring attachment element may be used for fall arrest only in rescue, work positioning, rope
access, and other ANSI Z359.1 recognized applications where the personal fall arrest system limits
the maximum free fall distance to 2 ft. (0.6m) and limits the maximum arrest force to 900 lbs. (4.0kN).
• Side and front D-rings should be used for positioning only. (Note front D-ring exception above.)
• Shoulder D-rings should be used for retrieval only.
• Never attach non-locking snap hooks to a harness D-ring.
• Never attach rebar (pelican) hooks to a harness D-ring.
• Body belts should be used for positioning only.

CONNECTING DEVICES

• Make only compatible connections.
• Use only connecting devices containing locking snap hooks or auto-locking carabiners.
• Always visually check that each snap hook and carabiner freely engages the D-ring or anchor
point, and that its keeper is completely closed and locked.
• Never disable or restrict locking keeper or alter connecting device in any way.
• Make sure snap hook/carabiner is positioned so that its keeper is never load bearing.
• The use of shock absorbers is required to reduce fall arresting forces.
• Tie-off in a manner which ensures a lower level will not be struck should a fall occur.
• Connect in a manner that limits free fall to the shortest possible distance. [6ft. (1.8m) maximum]
• Never allow a retractable lanyard or lifeline to become slack.
• Never allow a lanyard, or either leg of a two-legged lanyard, to pass under or entwine around the
user's arms, legs, neck or any other obstacle.
• Do not tie knots in lanyards or lifelines, or wrap around sharp, rough edges, or small diameter
structural members.
• Do not attach multiple lanyards together, or attach a lanyard back onto itself unless it is specifically
designed for that purpose.
