1.0 APPLICATIONS
1.1 PURPOSE:
LAD-SAF
®
fl exible cable ladder safety systems are designed to provide protection against falling
for persons connected to the system while climbing fi xed ladders or similar climbing structures.
A. APPLICATIONS: LAD-SAF
®
systems include installations on fi xed ladders or ladder like climbing
surfaces that are part of a structure. Examples include; water tank ladders, mono poles (wood, steel, or
concrete) buildings, manways, antenna structures, and towers.
1.2 LIMITATIONS: LAD-SAF
®
systems are not intended to be installed on portable ladders. These systems are
designed for use on ladders that are generally vertical. Ladders must be at least 75 degrees from horizontal
for proper system operation, except for curved top bracket installations. The following application limitations
must be considered before installing or using the LAD-SAF
®
system.
A. LADDER STRUCTURE: The ladder structure to which the system is installed must be capable of
withstanding the loads applied by the system in the event of a fall (see Section 2.3).
B. SYSTEM CAPACITY: The number of users allowed on the system at one time varies depending on the
type of system and installation. Generally, system capacities range from one to four users. See sections
2.0 and 3.0 for more information on capacity limitations. System capacities are based on a maximum
user’s weight, including tools and clothing, of 310 lbs (140.6 kg).
C. FALL CLEARANCE: Fall clearance below the feet of the user and the ground or other surfaces must not
be less than 7 ft. (2 m).
D.
ENVIRONMENTAL
HAZARDS:
Use of this equipment in areas with environmental hazards may
require that additional precautions be taken to reduce the possibility of injury to the user or damage
to the equipment. Hazards may include, but are not limited to: high heat caused by welding or metal
cutting; caustic chemicals; seawater; high voltage power lines; explosive or toxic gases; moving
machinery; sharp edges.
E. COMPONENT
COMPATIBILITY:
LAD-SAF
®
systems must be installed and used as a complete
system. Only DBI-SALA’s detachable cable sleeve (see Figure 5) may be used with this system. DBI-
SALA recommends using a full body harness with a front attachment for ladder climbing. A body belt
is not recommended for use with the LAD-SAF
®
system. If a fall occurs when using a body belt it may
cause unintentional release and possible suffocation because of improper body support. Substitutions of
equipment or system components must not be made without the written consent of DBI-SALA.
WARNING: Before using a LAD-SAF
®
Ladder System in combination with a climb assist system,
consult the climb assist system manufacturer’s instructions for any restrictions or limitations
concerning simultaneous use of these systems. Capital Safety has found that some connection
combinations may interfere with proper operation of the LAD-SAF
®
Detachable Sleeve and may result
in failure to arrest a fall. Avoid connecting the sleeve used on the LAD-SAF
®
Ladder System into the
same harness connection D-ring as is occupied by the climb assist system. Ensure that movement of
the arm of the LAD-SAF
®
sleeve is not restricted or interfered with by the climb assist system or its
connectors. Failure to heed this warning may result in serious injury or death.
F. TRAINING:
This equipment is intended to be installed and used by persons who have been trained in
its correct application and use.
1.3 Refer to applicable local, and national requirements governing this equipment for more information on
ladder safety systems and associated components, including OSHA 1910.27.
2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS AND SUBSYSTEMS: This equipment is designed for use with DBI-
SALA approved components and subsystems. The use of non-approved components and subsystems may
jeopardize compatibility of equipment, and could affect the safety and reliability of the complete system.
2.2 COMPATIBILITY OF CONNECTORS: Connectors used with this system (hooks, carabiners, D-rings)
must be capable of supporting a minimum of 5,000 lbs (22.2 kN). Use caution to assure compatibility of
hooks and the connection point. See section 4.4 on making connections. Non-compatible connectors may
unintentionally disengage (roll-out). Connectors must be compatible in size, shape, and strength. Self
closing/self locking connectors are highly recommended by DBI-SALA.
