1.0 Warnings and Important Informaon
This product is part of a personal fall arrest, restraint, work posioning, suspension, or rescue system. A Personal Fall Arrest System (PFAS) is
typically composed of an anchorage and a Full Body Harness (FBH), with a connecng device, i.e., a Shock Absorbing Lanyard (SAL), or a
Self-Retracng Lanyard (SRL), aached to the dorsal D-ring of the FBH.
These instrucons must be provided to the worker using this equipment. The worker must read and understand the manufacturer’s instrucons for
each component or part of the complete system. Manufacturer’s instrucons must be followed for proper use, care, and maintenance of this
product. These instrucons must be retained and be kept available for the worker’s reference at all mes. Alteraons or misuse of this product, or
failure to follow instrucons, may result in serious injury or death.
A Fall Protecon Plan must be on le and available for review by all workers. It is the responsibility of the worker and the purchaser of this
equipment to assure that users of this equipment are properly trained in its use, maintenance, and storage. Training must be repeated at regular
intervals. Training must not subject the trainee to fall hazards.
Consult a doctor if there is reason to doubt your tness to safely absorb the shock of a fall event. Age and tness seriously aect a worker’s ability
to withstand falls. Pregnant women or minors must not use this equipment.
ANSI limits the weight of fall protecon equipment users to a maximum of 310 lbs. Products in this manual may have a rated capacity exceeding
ANSI capacity limits. Heavy users experience more risk of serious injury or death due to falls because of increased fall arrest forces placed on the
user’s body. In addion, the onset of suspension trauma aer a fall event may be accelerated for heavy users.
The user of the equipment discussed in this manual must read and understand the enre manual before beginning work.
NOTE: For more informaon consult the ANSI Z359 body of standards.
• Avoid moving machinery, thermal, electrical, and/or chemical hazards as contact may cause serious injury or death.
• Avoid swing falls.
• Follow the weight restricons and recommendaons in this manual.
• Remove from service any equipment subjected to fall arrest forces.
• Remove from service any equipment that fails inspecon.
• Do not alter or intenonally misuse this equipment.
• Consult FallTech when using this equipment in combinaon with components or subsystems other than those described in this manual.
• Do not connect rebar hooks, large carabiners, or large snap hooks to the FBH dorsal D-rings as this may cause a roll-out condion and/or
unintenonal disengagement.
• Avoid sharp and/or abrasive surfaces and edges.
• Use cauon when performing arc welding. Arc ash from arc welding operaons, including accidental arcs from electrical equipment, can
damage equipment and are potenally fatal.
• Examine the work area. Be aware of the surroundings and workplace hazards that may impact safety, security, and the funconing of fall arrest
systems and components.
• Hazards may include, but are not limited to, cable or debris tripping hazards, equipment failures, personnel mistakes, or moving equipment
such as carts, barrows, fork lis, cranes, or dollies. Do not allow materials, tools, or equipment in transit to contact any part of the fall arrest
system.
• Do not work under suspended loads.

2.1 Purpose: The Conned Space Davit is designed to work as part of a system to raise or lower a person or material to work in a conned
space for entry, retrieval, fall arrest applicaons, and material handling. The Conned Space Davit is a modular design and allows
mulple conguraons with oponal Davit Arms, Lower Mast Extensions, and Bases.
2.2 Applicaon Limits: The FallTech Conned Space Davit is a dynamic anchorage system that will vary in its performance depending upon
congured oset. Care should be taken to understand the capacity of the system and anchorage strength requirements.
2.3 System Capacity: The maximum capacity of the Conned Space Davit is one worker for conned space entry and egress, with the
worker weighing no more than 310lbs (140kg) including clothing, tools, etc. For rescue applicaons, the Conned Space Davit has a
maximum capacity of two workers with each worker weighing no more than 310lbs including clothing, tools, etc.
2.4 Davit Anchorage Strength: When using the FallTech Conned Space Davit with the 3-Piece Portable Base, the mounng surface must
support 5000lbs. When using the FallTech Conned Space Davit with any other base, please refer to the user instrucon manual

2.0 Applicaon
3.0 System Requirements
3.1 Compability of Connectors: Connectors are considered to be compable with connecng 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 FallTech if you have any quesons about compability. Connectors must be compable
with the anchorage or other system components. Do not use equipment that is not compable. Non-compable connectors
may unintenonally disengage. Connectors must be compable in size, shape, and strength. Self-closing, self-locking snap hooks
and carabiners are specied by OSHA and ANSI Z359.12.
3.2 Compability of Components: Equipment is designed for use with approved components and subsystems only. Substuons or
replacements made with non-ANSI Z359 compliant components or subsystems may jeopardize compability of equipment and may aect
the safety and reliability of the complete system, see Figure 1. Ensure compability between the connectors if non-FallTech components
are used for fall protecon.
3.3 Connectors: Only use self-locking snap hooks, rebar hooks, and carabiners with this equipment. Only use connectors that are suitable to
each applicaon. Ensure all connecons are compable in size, shape and strength. Do not use equipment that is not compable. Visually
ensure all connectors close and lock completely. Connectors (snap hooks, rebar hooks, and carabiners) are designed for use only
as specied in this manual.

4.0 Installaon and Use
4.1 General Rescue Requirements: The equipment specied in this manual is designed to work as part of a system to help facilitate non-entry
rescue and entry rescue from conned spaces.
Conned spaces vary in size, shape, conguraon, and hazard. The equipment/device(s) detailed in this manual may not be suitable
for use during some permit-required conned space entries. Hazards such as entanglement, electric arc, engulfment, and general li
obstrucons may interfere with safe rescue and cause greater harm to the entrant.
All conned space entries should be planned whenever possible in such a manner that any foreseeable hazard is migated and non-entry
rescue can be facilitated.
In the case that non-entry rescue is not feasible, a rescue plan must be in place that provides rescuers with knowledge about the specic
conned space hazards they may encounter during a rescue, training on appropriate rescue methods for the conned space they will be
entering, and the correct equipment and PPE to perform the entry rescue. Please reference OSHA code CFR 1926.1211 and ANSI
Z117.1-2016 for further details on employer responsibilies in preparing for both entry and non-entry rescue.
4.2 System Conguraons for Non-Entry Rescue Methods: When entering a permit-required conned space, non-entry rescue is required
unless retrieval equipment would increase the overall risk of entry or would not contribute to the rescue of the worker. Mechanical
devices must be available to retrieve personnel from vercal type permit spaces more than 5 feet deep. When using mechanical devices
for non-entry rescue, consideraon must be given to the means of entry/egress, the migaon of fall hazards and the method of
emergency retrieval.
4.2.1 Single Line – Winch Only – Entry/Egress Using Ladder
When a single mechanical device is used for non-entry rescue into a conned space it serves only as backup to the worker’s primary
entry/egress method. In most cases the primary means of entry/egress into a vercal conned space is a ladder. When using only a
winch as the backup to the entrant’s primary means of entry and egress, the aendant should take care to keep the winch line taut to
avoid any potenal overload due to a fall event on the winch line. The winch is not a fall arrest device and must not be subjected to fall
forces. The winch is for emergency retrieval only. See Figure 2.
4.2.2 Single Line – 3-Way Only – Entry/Egress Using ladder
When a single mechanical device is used for non-entry rescue into a conned space it serves only as backup to the worker’s primary
entry/egress method. In most cases the primary means of entry/egress into a vercal conned space is a ladder. When using an SRL-R
only as a back up to the worker’s primary means of entry and egress the device cable will pay freely in and out of the housing as
the entrant moves into the vercal conned space. In the event the entrant falls the SRL-R will arrest the fall and reduce fall forces
applied to the body. The aendant may then engage the backup emergency retrieval winch to raise the entrant out of the conned
space. The emergency retrieval winch is not to be used for ordinary entry/egress in and out of the conned space. See Figure 3.

4.2.3 Dual Line – Winch and SRD/Alternate PFAS - Entry/Egress Using Ladder
When a conned space has an exisng ladder but the aendant is unable to maintain a taut winch line as the entrant descends and
ascends from the conned space, it is possible to use a regular SRD or Fall Arrestor Connector Subsystem (FACSS) to provide protecon
from impacng and overloading the winch during a fall event.
In this case the PFAS provides fall protecon as the worker freely moves vercally, and the winch provides backup as the emergency
retrieval device from the conned space. See Figure 4.
4.2.4 Dual Line – Winch and 3-Way – Entry/Egress Using a Winch
When no alternate method of entry/egress (such as a ladder) exists the conned space entrant will be suspended, raised and lowered
with the winch line aached to a shoulder yoke or sternal D-Ring of a Full Body Harness. An SRL-R is then aached to the dorsal
D-ring of the Full Body Harness to provide fall arrest and emergency retrieval. Suspended workers are required to have a backup system
to their primary means of entry/egress that will limit fall forces to the body and provide emergency retrieval in the event of a winch
malfuncon. See Figure 5.
