The employer must provide training in the proper use, inspection, and
maintenance of all components in the system, and these instructions
can be used as part of that training. The equipment should be used
ONLY in accordance with these instructions, local ordinances and
codes, the applicable OSHA and ANSI standards, and the employer’s
safety plan. Alterations or misuse of this product or failure to follow
instructions may result in serious injury or death.
IF YOU HAVE ANY QUESTIONS ABOUT ANYTHING IN THESE
INSTRUCTIONS, THE EQUIPMENT, OR PROPER USE OF THE
EQUIPMENT, CONTACT WERNER CO. FOR MORE INFORMATION.
I. Before Using the D-Bolt Anchor
Before using this equipment the user should take certain steps to
ensure that it is in suitable condition and safe for use. Users must
read and understand these instructions. It is the employer’s obligation
to ensure that all users have been trained in safe work procedures
as well as in the use and limitations of fall protection equipment. All
users should be aware of and comply with all applicable OSHA, ANSI
and local or regional regulations concerning fall protection equipment
and its use.
a. Inspect
Examine all equipment thoroughly, daily before use by the user,
and periodically by a competent person who is not the user.
1. Ensure that the D-Bolt Anchor is free from rust, corrosion and any
damage. Clean with warm soapy solution to prevent damaging
the D-Bolt Anchor or structure.
ENGLISH
2. Ensure that the nut is securely tightened and the Lock Washer
remains engaged. If the nut and lock washer become loose, re-
Page 4
D-BOLT ANCHORS
USER INSTRUCTIONS
tighten the nut to the torque speci ed in section II.f.
3. Inspect the D-Bolt Anchor to ensure there are no cracks, dents
or marks on the anchorage.
4. Make sure labels are attached to the D-Bolt Anchor and are
legible.
5. Record the inspection date and results in the Inspection and
Maintenance Log.
6. If inspection reveals a defective condition or abnormalities in
any of these areas, remove unit from service immediately. A
competent person should be consulted to determine if that item
is safe for continued use or if it should be destroyed.
IMPORTANT: If this equipment has been subjected to forces
resulting from the arrest of a fall, it must be immediately removed
from service.
b. Compatibility
Werner Co. equipment is designed for use with Werner Co. approved
components and subsystems only. Substitutions or replacements
made with non-approved components or subsystems may
jeopardize compatibility of equipment and may affect the safety and
reliability of the complete system.
Connectors are considered to be 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.
Contact Werner Co. if you have any questions about compatibility.
Connectors (hooks, carabiners, and D-rings) must be capable of
supporting at least 5,000 pounds (22.2kN). 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. Connectors must be compatible in
size, shape, and strength. Self locking snap hooks and carabiners
are required by ANSI Z359 and OSHA.
c. Fall Protection Plan
Plan your fall arrest or restraint system before starting your work.
Take into consideration all factors affecting your safety at any
time during use. The following list gives some important points to
consider when planning your system:
Page 5
ENGLISH
1. ANCHORAGE: Select a rigid anchorage point that is capable of
supporting the required loads. See section II.b.
The anchorage location must be carefully selected to reduce
possible free fall and swing fall hazards and to avoid striking an
object during a fall. For restraint systems the anchorage must be
located such that no vertical free fall is possible. For fall arrest
systems OSHA requires the anchorage be independent of the
means suspending or supporting the user.
2. FREE FALL: Do not work above the anchorage level; increased
fall distance will result. Personal fall arrest systems must be
rigged such that the potential free fall is never greater than 6
feet (1.83 m). Restraint systems must be rigged such that there
is no possible vertical free fall.
3. FALL ARREST FORCES: The assembled fall arrest system
must keep fall arrest forces below 1,800 pounds (8 kN) when
used with a full body harness. Do not use a body belt for fall
arrest.
SWING FALL
4. SWING FALLS: Swing
falls occur when the
Anchorages
HAZARD
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 or death.
Minimize swing falls by
working as close to the
Correct Incorrect
anchorage point as possible. Do not permit a swing fall if injury
could occur. Swing falls will signi cantly increase the clearance
required when a self-retracting lifeline or other variable length
connecting subsystem is used.
ENGLISH
Page 6
5. FALL CLEARANCE: Make certain enough clearance exists
in your fall path to prevent striking an object. The amount of
clearance needed is dependent upon the type of connecting
subsystem used and anchorage location. See connecting
subsystem user instructions for more information.
6. RESCUE: Should a fall occur, the user (employer) must have a
rescue plan. If a worker falls and is forced to remain suspended
for any length of time, physical damage to the body or even
death can result. For this reason Werner, OSHA, ANSI and
D-BOLT ANCHORS
USER INSTRUCTIONS
most local regulations require that a rescue plan and the means
to implement the rescue plan are in place before use of this
equipment.
7. AFTER A FALL: Any equipment which has been subjected
to the force of arresting a fall must be removed from service
immediately.
WARNING!
Never connect more than one personal fall arrest or restraint system
to this device.
WARNING!
Follow manufacturer’s instructions for associated equipment used in
your fall protection or restraint system.
d. Training
OSHA, ANSI, and most local ordinances require that workers using
this product receive adequate training before use of this product.
These instructions and their entire contents should be a part of that
training.
II. D-Bolt Anchor Installation and Use
WARNING!
Do not alter or intentionally misuse this equipment. Consult with
Werner Co. if using this equipment 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!
Do not use this device if you are unable to tolerate the impact of
a fall arrest. Age and tness can seriously affect your ability to
withstand a fall. Pregnant women and minors must not use this
equipment.
a. Making Connections
1. Only use self-locking snap hooks and carabiners with this
equipment. Only use connectors that are suitable to each
Page 7
ENGLISH
application. 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.
2. Werner Co. connectors (snap
hooks and carabiners) are
designed to be used only as
speci ed in each product’s
user’s instructions. See
inappropriate connections.
INAPPROPRIATE CONNECTIONS
NO! NO! NO! NO!
PROPER CONNECTION
NO!NO!NO!NO!
WARNING!
Large throat opening snap hooks should 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. Large throat snap
hooks are designed for use on xed structural elements such as
rebar or cross members that are not shaped in a way that can capture
the gate of the hook.
Werner Co. snap hooks and carabiners should NOT be
connected:
i. to a D-ring to which another connector is attached.
ii. in a manner that would result in a load on the gate. If the
connecting element that a snap hook or carabiner attaches
to is undersized or irregular in shape, a situation could occur
where the connecting element applies a force to the gate of
the snap hook or carabiner. This force may cause the gate
ENGLISH
(of either a self-locking or a non-locking snap hook) to open,
allowing the snap hook or carabiner to disengage from the
Page 8
connecting point.
D-BOLT ANCHORS
USER INSTRUCTIONS
iii. in a false engagement, where features that protrude from
the snap hook or carabiner catch on the anchor and without
visual con rmation seems to be fully engaged to the anchor
point.
iv. to each other.
v. directly to webbing or rope lanyard or tie-back (unless
the manufacturer’s instructions for both the lanyard and
connector speci cally allow such a connection).
vi. to any object which is shaped or dimensioned such that the
snap hook or carabiner will not close and lock, or that rollout could occur.
3. When using an energy-absorbing lanyard, connect the energy
absorber “pack” end to the harness.
b. Anchorage Strength
Depending on the application, the anchorage to which the D-Bolt
Anchor is installed must meet strengths as given below:
1. FALL ARREST: Anchorages selected for personal fall arrest
systems (PFAS) shall have a strength capable of sustaining
static loads, applied in the directions permitted by the PFAS, of
at least; (A) 3,600 pounds (16kN) when certi cation exists (see
ANSI Z359.1 for certi cation de nition), or (B) 5,000 pounds
(22kN) in the absence of certi cation. When more than one
PFAS is attached to an anchorage, the anchorage strengths
set forth in (A) and (B) above shall be multiplied by the number
of personal fall arrest systems attached to the anchorage. Per
OSHA 29 CFR 1926.500 and 1910.66; Anchorages used for
attachment of PFAS shall be independent of any anchorage
being used to support or suspend platforms, and capable of
supporting at least 5,000 pounds (22kN) per user attached, or be
designed, installed, and used as part of a complete PFAS which
maintains a safety factory of at least two, and is supervised by
a quali ed person.
2. RESTRAINT: Anchors selected for restraint applications must be
attached to a roof member capable of sustaining a static load of
at least 3,000 pounds (13 kN) applied in any direction permitted
by the restraint system when in use. Each roof member anchor
installation must be independently capable of sustaining this
load.
Page 9
ENGLISH
WARNING!
Restraint anchorages may only be used where there is no possible
vertical free fall. Restraint anchorages do not have sufficient strength
for fall arrest. Do not connect personal fall arrest systems to restraint
anchorages.
c. Connector
For fall arrest systems Werner Co. recommends using energy
absorbing lanyards incorporating self locking snap hooks or selfretracting lifelines. Lanyards labeled ANSI A10.14 Type II must
not be used for fall arrest applications. All lanyards must have a
minimum breaking strength of 5,000 pounds (22kN).
NOTE: Applications such as working near high voltage may require
special lifeline materials, consult Werner Co. before using such
lifelines.
d. Body Support
The recommended body support for fall arrest applications is a full
body harness. For restraint applications a body belt may be used.
e. Mounting location
The D-Bolt Anchor should be positioned on the mounting surface
ENGLISH
so that the attached connector will never be subjected to dynamic
loading on the keeper system . Werner D-Bolt Anchors may
be installed on overhead horizontal or vertical surfaces. Other
installation applications must be approved by Werner Co.
1. The entire base of the D-Bolt Anchor must be ush with the
mounting surface.
2. The area of the mounting surface for the D-Bolt Anchor must
be such that no dynamic forces get applied to the attached
connector’s keeper system.
