of the equipment. The user must understand how to safely and effectively use the 021-4042 Wood Truss
Anchor, and all fall protection equipment used in conjuction with the Wood Truss Anchor.
APPLICABLE SAFETY STANDARDS
When used according to instructions, the 021-4042 Wood Truss Anchor meets all applicable ANSI
Z359.1 standards and OSHA regulations for fall protection. Applicable standards and regulations depend
on the type of work being done, and may include state-specific regulations. Refer to local, state, and
federal (OSHA) requirements for additional information concerning the governing of occupational safety
regarding Personal Fall Arrest Systems (PFAS).
WORKER CLASSIFICATIONS
Understand the definitions of those who work in proximity of or may be
exposed to fall hazards.
Qualified Person:
“Qualified” means one who, by possession of a recognized degree, certificate,
or professional standing, or who by extensive knowledge, training, and experience, has successfully

project.
Competent Person:
“Competent person” means one who is capable of identifying existing and predict
-
able 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

PRODUCT SPECIFIC APPLICATIONS
Purpose:
The Safewaze 021-4042 Wood Truss Anchor is designed to be used as part of a Personal
Fall Arrest System (PFAS).
- A competent person shall train users on this equipment in accordance with OSHA
and ANSI.
- Never exceed a free fall distance of 6 ft. A free fall of more than 6 ft could cause
excessive arrest forces that could result in serious injury or death.
- The Safewaze 021-4042 Wood Truss Anchor has a maximum capacity of 310 lbs
including any tools, clothing, accessories, etc..., unless otherwise rated by
Safewaze.
- Structures for attachment of Safewaze 021-4042 Wood Truss Anchor shall support
a minimum 1,800 lbs or be designed with a safety factor of two by a Qualified Person.
- All Safewaze anchors must IMMEDIATELY be removed from service if subjected
to fall arrest forces.
- Safewaze anchors shall be inspected by the end user prior to each usage and
by a Competent Person other than the user every 6 months. These inspections shall
be documented.

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 a
MINIMUM 2’ safety factor, deceleration distance, user height, length of lanyard/SRL, and all other
applicable factors. (See Figure 1)

(including all clothing, tools, and equipment) is 130-310 lbs
FIGURE 1
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 in line with the anchor point as possible. Swing falls significantly increase the likelihood
of serious injury or death in the even of a fall. (See Figure 2)

COMPATIBILITY OF CONNECTORS
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. (22.2 kN). Connectors must be compatible with the anchorage
or other system components (see Figure 4).
Do not use equipment that is not compatible
. Non-
compatible connectors may unintentionally disengage (see Figure 3). Connectors must be compatible
in size, shape, and strength. Self-locking snap hooks and carabiners are required by ANSI Z359 and
OSHA guidelines. Contact Safewaze if you have any questions about compatibility
.

NOTE:
SOME SPECIALITY CONNECTORS HAVE ADDITIONAL
REQUIREMENTS. CONTACT SAFEWAZE WITH QUESTIONS.

FIGURE 4 - INAPPROPRIATE CONNECTIONS
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 (snap hooks and carabiners) are designed to be used only as specified in each
product’s user’s instructions. 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). NOTE:
Large snap hooks must not be connected to objects which will result in a load on the gate if the hook
twists or rotates. Snap hooks marked with ANSI Z359.12 and are equipped with a 3,600 lb (16 kN)
gate. Check the marking on your snap hook to verify its compatibility.
NOTE:
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 Z359.1-2007 or ANSI Z359.12 and is equipped with a
3,600 lb (16 kN) gate. Check the marking on your snap hook to verify that it is appropriate
for your application.
•
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.
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.

SPECIFIC ANCHOR APPLICATIONS
Personal Fall Arrest:
The 021-4042 Wood Truss Anchor is designed as
an anchor point to support a maximum of 1 Personal Fall Arrest System
(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. User must be
equipped with a means of limiting the dynamic forces exerted on the user
during the arrest of a fall to a maximum of 900 lbf (4kN).
Restraint:
The 021-4042 Wood Truss Anchor is 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 harness are
Dorsal D-ring, Chest D-ring, Side D-rings, and Shoulder D-rings.
Work Positioning:
The 021-4042 Wood Truss Anchor is 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 Wood Truss 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’. For positioning
applications, the allowable attachment points to harness are the Side
D-rings.
Rescue/Confined Space:
The 021-4042 Wood Truss Anchor is
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 a Wood
Truss Anchor is attached must withstand loads applied in the directions
permitted by the system of at least 3,000 lbs. NO free fall is permitted.
For rescue applications, the allowable attachment points to harness are
Dorsal D-ring, Chest D-ring and Shoulder D-rings.
All above referenced applications have a worker weight capacity range of 310 lbs
(including all clothing, tools, and equipment).
