Per OSHA 1926.500 and 1910.66: Anchorages used for attachment of personal fall arrest
systems shall be independent of any anchorage used to support or suspend platforms and
capable of supporting at least 5,000 pounds (22.2 kN) per attached user; or, be designed,
installed, and used as part of a complete PFAS which maintains a safety factor of at least two
and is under the supervison of a qualifi ed person.
B. RESTRAINT: Anchorages selected for restraint and travel restraint systems shall have a
strength capable of sustaining static loads applied in the directions permitted by the system of
at least:
•
1,000 pounds (4.5 kN) for non-certifi ed anchorages; or,
•
Two times the forseeable force for certifi ed anchorages.
When more than one fall arrest systems is attached to an anchorage, the applicable strength
requirement should be modifi ed by the number of systems attached to the anchorage.
3.0 OPERATION AND USE
WARNING: Do not alter or intentionally misuse this equipment. Consult DBI/SALA when using this equipment
in combination with components or subsystems other than those described in this manual. Some subsystem
and component combinations may interfere with the operation of this equipment. Use caution when using this
equipment around moving machinery, electrical hazards, chemical hazards, and sharp edges.
WARNING: Consult your doctor if there is reason to doubt your fi tness to safely absorb the shock from a fall
arrest. Age and fi tness seriously affect a worker's ability to withstand falls. Pregnant women or minors must not
use DBI/SALA Vertical Lifelines or subsystems.
3.1 BEFORE EACH USE of this equipment, carefully inspect it according to steps listed in section 5.0
of this manual.
3.2 PLAN your fall arrest or restraint system before using this equipment. Consider all factors that
will affect your safety during use of this equipment. Consider the following points when planning
your system:
A. ANCHORAGE: Select a rigid anchorage point that is capable of sustaining the loads specifi ed
in section 2.3. For fall arrest applications, select anchorage locations that will minimize free
fall and swing fall hazards. For restraint applications, locate the anchorages such that no
vertical free fall is possible.
B. FREE FALL: To avoid increased free fall distance, do not work above the anchorage level. Rig
personal fall arrest systems so that the free fall is limited to 6 ft. (1.8 m) (ANSI Z359.1). Rig
restraint systems such that no vertical free fall is possible.
C. FALL ARREST FORCES: The personal fall arrest system
must limit fall arrest forces to 1,800 lbs (8 kN). and
deceleration distance must not exceed 42 in. (1 m). Do not
use a body belt for fall arrest applications.
D. SWING FALLS: See Figure 5. Swing falls occur when the
anchorage point is not directly above the point where a
fall occurs. The force of striking an object in a swing fall
may cause serious injury. Minimize swing falls by working
as directly below the anchorage point as possible. Do not
permit a swing fall if injury could occur.
