1.0 APPLICATIONS
1.1 PURPOSE:
DBI-SALA Energy Absorbing Lanyards and Energy Absorbers are intended to be used as part of a personal
fall arrest system. Applications for these products include inspection work, construction and demolition, maintenance, oil
production, confined space rescue, and similar activities where there exists the possibility of a fall. This equipment is specially
designed to dissipate fall energy and limit fall arrest forces transferred to the body.
1.2 LIMITATIONS:
The following application limitations must be considered before using this product:
A. CAPACITY:
This equipment is for use by persons with a combined weight (person, clothing, tools, etc.)
of no more than 310 lbs. (140.6 kg). CSA models meet Z25911-05 E4 or E6 classifications. See back
cover for associated capacities and model numbers.
B. PHYSICAL AND ENVIRONMENTAL HAZARDS:
Use of this equipment in areas containing physical
or environmental hazards may require that additional precautions be taken to reduce the possibility
of damage to this equipment or injury to the user. Hazards may include, but are not limited to: high
heat, strong or caustic chemicals, corrosive environments, the possibility of electric current flowing
through this equipment when working near high voltage power lines, explosive or toxic gases,
moving machinery, sever cold, or sharp edges. Contact DBI-SALA if you have any questions about the
application of this equipment in areas where physical or environmental hazards are present.
C. TRAINING:
This equipment is intended to be installed and used by persons who have been properly
trained in its correct application and use.
1.3
Refer to national standards including ANSI Z359 (.0, .1, .2, .3, and .4), family of standards on fall protection, ANSI A10.32,
and applicable local, state, and federal (OSHA) requirements governing occupational safety for more information on Energy
Absorbing Lanyards, Energy Absorbers and associated components. In Canada, see the Z259 group of CSA Standards.
2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF CONNECTORS:
DBI-SALA equipment is designed for use with DBI-SALA approved
components and subsystems only. Substitutions or replacements made with non-approved components
or subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the
complete system.
COMPATIBILITY:
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. See Figure 2.
Connectors must be compatible in size, shape, and strength regardless of orientation. Self-locking snap hooks
and carabiners are required by ANSI Z359.1 and OSHA. Contact DBI-SALA if you have any questions about
compatibility.
Connectors ( hooks, carabiners, and D-rings) must be capable of supporting a tensile load of at least 5,000 lbs. (22.2
kN). Per ANSI Z359.1, connector gates must be able to withstand a load of 3,600 lbs (16 kN): the face of the gate
must withstand 3,600 lbs (16 kN); the side of the gate must withstand 3,600 lbs (16kN), and the minor axis of a
snap hook or carabiner must withstand 3,600 lbs (16 kN), except for those with captive eyes.
If the connecting element that a snap hook (shown) 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 (of either a self-locking or a non-locking snap hook) to open, allowing the snap hook or carabiner to disengage
from the connecting point.
1. Force is applied to the
snap hook.
2. The gate presses against
the connecting ring.
3. The gate opens allowing the
snap hook to slip off.

2.2 MAKING CONNECTIONS:
Only use self-locking snap hooks and carabiners with this equipment. Only use
