I. Applications:
A.
Purpose:
The purpose of the portable truss anchor is to be used as an anchor point of a personal fall arrest system. It is
designed to be used with a full body harness with back D-Ring, a carabiner, and a connecting subsystem consisting of
a self-retracting lifeline (SRL).
B.
Limitations:
•
Capacity – The portable truss anchor is not to be used by persons with a total weight over 420 pounds. This
total weight includes body weight, and the weight of any clothing, tools, and equipment.
•
Fall Clearance – In general industry, when working on a surface 4 feet or higher from ground level, per
OSHA, fall protection is required. This system is designed to prevent serious injury or death in the event of a
fall. There must be sufficient clearance below the user to arrest a fall before the user strikes the ground or

least 6'6" from the ground surface when user is in upright standing
position to prevent serious injury and/or death.
•
Swing Falls – A swing fall occurs when the anchor point is not directly above
where a fall occurs. Minimize this hazard by working with the anchor overhead
as much as possible. The suggested safe work area is within a 30º downward facing cone from an overhead
anchor point to harness D-Ring (See Figure 3). The extra force of striking an object in a swing fall may cause
serious injury or death and should therefore be avoided whenever possible. The required clearance
significantly increases when a variable length subsystem such as a web lanyard is used.
•
Environmental Hazards – Extra precautions may be required to safely use this system if other hazards in the
surrounding environment exist. Such hazards include, but are not limited to: extreme temperatures, power
lines, moving machinery, sharp edges, corrosion, and toxic fumes. Please contact DFP if you have concern
of any such conditions existing where this equipment is being used.
•
Training – This equipment is only permitted to be installed and used by competent persons that have been
trained in the correct use and application of the portable truss anchor.
C.
Standards:
•
Please refer to all families of standards regarding occupational safety for more information on work positioning
systems and fall protection. These include ANSI, OSHA, and any applicable local or state requirements.
II. System Requirements:
A.
Compatibility:
•
Compatibility shall follow all requirements of OSHA 1926.502 (d) as well as these instructions and those of the
SRL, harness, and other components.
•
The design of the portable truss anchor is made for use only with approved components and subsystems.
Non-approved components and subsystems may jeopardize the compatibility of equipment and affect the
safety and reliability of the complete system.

other obstruction. Clearance required may increase depending on but not
limited to some of the following factors: worker height, worker weight,
movement of attachment element, elevation of anchorage connector, SRL
length, other obstructions, deceleration distance and free fall distance.
