ALLOWED ANCHOR APPLICATIONS
LIMITATIONS
Always select a lanyard and anchor point location that limits free fall and swing fall as much as
possible. A free fall of more than 6 ft. could cause excessive arrest forces that could result in
serious injury or death.
Structures for the attachment of the Concrete Anchor Strap shall support a minimum 5,000 lbs. (22
kN) or be designed with a safety factor of two to one by a Qualified Person.
Fall Clearance:
There must be sufficient clearance below the anchorage connector to arrest a fall
before the user strikes the ground or an obstruction. When calculating fall clearance, account for all
applicable factors (Figure 1). A Competent Person must reference the entire system’s components
to calculate Fall Clearance.
FIGURE 1: FALL CLEARANCE DIAGRAM
*These diagrams are examples of fall clearance calculations ONLY.
Swing Falls:
Prior to installation or use, make considerations for eliminating or minimizing all
swing fall hazards. Swing falls occur when the anchor is not directly above the location where
a fall occurs. Always work as close to, or in line with, the anchor point as possible. Swing falls
significantly increase the likelihood of serious injury or death in the event of a fall (Figure 2)
FIGURE 2: SWING FALL
WORKER CLASSIFICATIONS
Read and understand the definitions of those who work in proximity of, or may be exposed
to, fall hazards:
Qualified Engineer:
“Qualified Engineer” means a person with a Bachelor of Science in
Engineering degree from an accredited college or university. They are able to assume personal
responsibility for the development and application of engineering science and knowledge in the
design, construction, use, and maintenance of their projects.
Qualified Person:
“Qualified Person” means one who, by possession of a recognized degree,
certificate, or professional standing, or who by extensive knowledge, training, and experience, has
successfully demonstrated their ability to solve or resolve problems relating to the subject matter,
the work, or the project.
Competent Person:
“Competent Person” means one who is capable of identifying existing and
predictable hazards in the surroundings or working conditions which are unsanitary, hazardous,
or dangerous to employees, and who has authorization to take prompt corrective measures to
eliminate them.
Authorized Person:
“Authorized Person” means a person approved or assigned by the employer
to perform a specific type of duty or duties, or to be at a specific location or locations, at the jobsite.
It is the responsibility of a Qualified Person or Engineer to supervise the jobsite and ensure
safety regulations are complied with.
COMPATIBILITY OF COMPONENTS/CONNECTORS
•
Safewaze equipment is designed for, and tested with, associated Safewaze components or
systems. If substitutions or replacements are made, ensure all components meet the applicable
ANSI requirements. Read and follow manufacturer’s instructions for all components and
subsystems in your PFAS. Not following this guidance may jeopardize compatibility of equipment
and possibly affect the safety and reliability of the system.
• Connectors are compatible with connecting elements when they have been designed to work
together in such a way that their sizes and shapes do not cause their gate mechanisms to
inadvertently open regardless of how they become oriented.
• Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbs.
(22 kN).
• Connectors must be compatible with the anchorage or other system components.
•
Do not use equipment that is not compatible. Non-compatible connectors may unintentionally
disengage (Figure 3).
•
Connectors must be compatible in size, shape, and strength.
•
Self-locking snap hooks and carabiners are required by OSHA guidelines.
•
Some specialty connectors have additional requirements. Contact Safewaze if you have any
questions about compatibility.
FIGURE 3: UNINTENTIONAL DISENGAGEMENT
Using a connector that is undersized or irregular in shape (1) to connect a snap hook or carabiner
could allow the connector to force open the gate of the snap hook or carabiner. When force is
applied, the gate of the hook or carabiner presses against the non-compliant part (2) and forces
open the gate (3). This allows the snap hook or carabiner to disengage (4) from the connection
point.

ANCHORAGE INSTALLATION LOCATION
A Qualified Person or Engineer must conduct an analysis of the workplace and ensure the
anchorage location is capable of withstanding loads from a fall. An anchorage location selected
for a Personal Fall Arrest System (PFAS) must have a strength capable of sustaining a static load
applied in the direction permitted by the PFAS of at least:
•
5,000 lbs. (2267.9 kg) for non-certified anchorages, or
•
Two times the maximum arresting force for certified anchorages, or
•
3,100 lbs. for Rescue applications.
When more than one fall arrest system is attached to an anchorage, the strengths set forth in one
of the above shall be multiplied by the number of systems attached to the anchorage.
MAKING CONNECTIONS
Snap hooks and carabiners used with this equipment must be double locking and/or twist lock.
Ensure all connections are compatible in size, shape, and strength. Do not use equipment that is
not compatible. Ensure all connectors are fully closed and locked.
Safewaze connectors (hooks, carabiners, and D-rings) are designed to be used only as specified
in each product’s manual. See Figure 4 for examples of inappropriate connections. Do not connect
snap hooks and carabiners:
• To a D-ring to which another connector is attached.
• In a manner that would result in a load on the gate (with the exception of tie-back hooks).
• In a false engagement, where features that protrude from the snap hook or carabiner catch on
the anchor, and without visual confirmation seems to be fully engaged to the anchor point.
• To each other.
•
By wrapping the web lifeline around an anchor and securing to lifeline, except as allowed for
tie-back models.
•
To any object which is shaped or sized in a way that the snap hook or carabiner will not close
and lock, or that roll-out could occur.
• In a manner that does not allow the connector to align properly while under load.
FIGURE 4: INAPPROPRIATE CONNECTIONS
Large throat snap hooks must not be connected to standard size D-rings or similar objects which
will result in a load on the gate if the hook or D-ring twists or rotates, unless the snap hook
complies with ANSI Z359.12 and is equipped with a 3,600 lb. (16 kN) gate.

Restraint:
Safewaze Anchors are authorized for use in Restraint applications. The
structure to which the anchor is attached must withstand loads applied in the directions
permitted by the system of at least 1,000 lbs. NO free fall is permitted. Restraint
systems may only be used on surfaces with slopes up to 4/12 (vertical/horizontal). For
Restraint applications, the allowable attachment points to the harness are Dorsal,
Front/Sternal, Side, and Shoulder D-rings.
Work Positioning
:
Safewaze Anchors are authorized for use in Work Positioning
applications. Work Positioning allows a worker to be supported during suspension while
freeing both hands to conduct work operations. The structure to which the Anchor is
attached must withstand loads applied in the directions permitted by the system of at
least 3,000 lbs. Maximum allowable free fall is 2’ ft. For positioning applications, the
allowable attachment points to the harness are the Side D-rings.
Rescue/Confined Space
:
Safewaze Anchors are authorized for use in Rescue/
Confined Space applications. Rescue systems are utilized to safely recover a worker
from a confined location or after exposure to a fall. Composition of rescue systems
can vary based upon the type of rescue involved. The structure to which the Anchor
is attached must withstand loads applied in the directions permitted by the system
of at least 3,100 lbs. NO free fall is permitted. For rescue applications, the allowable
attachment points to the harness are Dorsal, Front/Sternal, and Shoulder D-rings.
Personal Fall Arrest
:
Safewaze Anchors are designed as an anchor point to support a
maximum of 1 PFAS when utilized for fall protection applications. The structure to which
the anchor is attached must withstand loads applied in the directions permitted by the
system of at least 5,000 lbs. (22 kN) or be designed with a safety factor of two to one.
Maximum allowable freefall is based on the connector used.
