NOTE:
Do not allow the lifeline to exceed a 30
degree working angle from the anchor point;
OR,
work outside of a 6 ft working radius from the anchor
point, whichever comes

BEFORE EACH USE:
Inspect this equipment carefully to ensure it is in good working condition. Check for worn or
damaged parts. Ensure all parts are present and secure. Check the entire system for damage and corrosion. Do
not use if inspection reveals an unsafe condition.
PLANNING:
Plan your system and how it will function before starting your work. Consider all factors that affect
your safety during use. Some important points to consider when planning your system are:
A. HAZARD EVALUATION:
Evaluate job site hazards prior to starting work. Consult applicable OSHA (or
CE) and industry standards for guidelines and regulatory requirements on equipment such as personal
fall arrest systems (PFAS).
B. WORK SITE GEOMETRY:
The use of the frame system and attached PFAS must be consistent with the
geometric requirements stated in the manufacturer’s instruction manual(s). Check for obstructions or
sharp edges in the work path. Avoid working where the user may swing and hit an object, or where lines
may cross or tangle with that of another worker.
C. FALL
CLEARANCE:
There must be sufficient clearance in your fall path to prevent striking an abject or
lower level in the event of a fall. A minimum of 6 ft. (1.8 m) from the working level to the lower level
or nearest obstruction is recommended but may vary with you application and attached PFAS. See the
PFAS manufacturers’ instructions.
D. SWING
FALLS:
Swing Falls occur when the anchorage point is not directly overhead. The force of
striking an object in a Swing Fall may cause serious injury or death. Minimize Swing Falls by maintaining
a work position as directly below the anchorage point as possible. In planning your system, increased
clearance is required with Self-Retracting Lifelines or other variable length subsystems to negate the
possibility of Swing Falls.
E. SHARP
EDGES:
Avoid working where components of the Boxed-Frame Rail Fall Arrest System and
attached subsystem(s) will contact with or abrade against unprotected sharp edges.
F. RESCUE:
When using this equipment, the employer must have a rescue plan and the means at hand to
implement it and communicate that plan to authorized persons, users, and rescuers.
G. AFTER A FALL:
Any equipment which has been subjected to the forces of arresting a fall or exhibits
damage consistent with the effect of fall arrest forces as described, must be removed from service
immediately and destroyed by the user, the rescuer, or an authorized person.
REQUIREMENTS FOR PERSONAL FALL ARREST SYSTEMS (PFAS):
PFAS used with the frame system must
meet applicable OSHA requirements.
The PFAS should be rigged to minimize any potential free fall and never allow a free fall greater than six (6) ft.
(1.8 m). The PFAS used with this equipment are required to include a full body harness as the body support
component. PFAS that incorporate full body harnesses must maintain fall arrest forces below 1,800 lbs. (8.0 kN)
and arrest the fall within 42 in. (1.1 m). Body belts, unless incorporated into a full body harness, are not allowed
for use with this equipment. A typical PFAS includes a full body harness, connecting subsystem or component (self
retracting lifeline or shock absorbing lanyard), and the necessary connectors to couple the system together.
PFAS may only be attached to the Trolleys which move along the Rail Assembly.
