3.1 HEAD
3.1.1 POSITIVE LOCKING PIN (1):
There are two plates welded to the underside of the
head near its center. A hole is drilled into each plate
and the ball lock pin fits through these aligned holes.
A thumb button on the end of the pin will release
pressure on the locking ball at the opposite end of the
pin. This allows disengagement and engagement of
the Positive Locking Pin during assembly and removal
of compatible accessories. The Positive Locking Pin is
the smaller diameter of the two pins on the underside
of the head. The plates and the Positive Locking Pin
are used together to create a temporary intermediate
anchorage connector for compatible accessories such
as the MSA Split-Mount Pulley, P/N 506222. Refer
to the separate User Instructions included with these
products for installation and use of each of these
optional components.
3.1.2 HITCH PIN (1):
There are two plates welded to the
underside of the head, A hole is drilled
into each plate and the hitch pin fits
through these aligned holes. A cotter pin
fits through a hole in the end of the hitch
pin and must be removed to disengage
the pin during assembly or removal of
compatible accessories. The hair pin
cotter must be in place on the hitch pin
during use of the pin. The plates and
the hitch pin are used together to create
an intermediate anchorage connector
for compatibleaccessories such as the
MSA Boom-Mounted Lynx Hoist, MSA
Dyna-Lock and MSA Lynx Rescuer.
3.1.3 MOUNTING HARDWARE FOR OPTIONAL LYNX TRIPOD ACCESSORIES:
3.1.3.1

5.1 COMPATIBILITY OF SYSTEM PARTS
5.1.1 COMPATIBILITY OF COMPONENTS AND SUBSYSTEMS:
Lynx Tripod anchorage connectors are designed to be used with MSA approved components and connecting
subsystems. Use of the Lynx Tripod with products made by others that are not approved in writing by MSA may
adversely affect the functional compatibility between system parts and the safety and reliability of the complete
system. Connecting subsystems must be suitable for use in the application (e.g. fall arrest, climbing protec-
tion, rescue or evacuation). MSA produces a complete line of connecting subsystems for each application.
Contact MSA for further information. Refer to the manufacturer’s instructions supplied with the component or
connecting subsystem to determine suitability. For fall arrest applications using the Lynx Tripod, the maximum
fall arrest force must not exceed 1,800 lbf (8 kN). Contact MSA with any questions regarding compatibility of
equipment used with the Lynx Tripod.
5.1.2 COMPATIBILITY OF CONNECTORS:
Connectors, suchas D-rings,snaphooks, andcarabiners, mustbe rated at5,000 lbf(22 kN)minimum breakingstrength.
MSA connectors meet this requirement. Connecting hardware must be compatible in size, shape, and strength.
Non-compatible connectors may accidentally disengage (“rollout”). Always verify that the connecting snaphook
or carabiner and the D-ring on a full body harness or Lynx Tripod anchorage connector are compatible. Use only
self-closing, self-locking snaphooks and carabiners (as defined and required by ANSI Z359.1) with the Lynx
Tripod.
5.1.3 ANCHORAGES AND ANCHORAGE CONNECTORS:
Anchorages for personal fall arrest systems must have a strength capable of supporting a static load, applied in
directions permitted by the system, of at least: (a) 3,600 lbf (16 kN) when certification exists, or (b) 5,000 lbf (22.2
kN) in the absence of certification. See ANSI Z359.1 for definition of certification. The Lynx Tripod is designed for
connection by a single personal fall arrest system. See section 7.1 for considerations in selecting an appro-
priate anchorage for use with the Lynx Tripod anchorage connector. See ANSI Z359.1, section 7.2.3. This
requirement is consistent with OSHA requirements under 20 CFR 1910, Subpart F, Section 1910.66, Appendix
C. In addition, it is recommended that the user of personal fall arrest systems refer to ANSI Z359.1, Section
7, for important considerations in equipment selection, rigging, use, and training. Contact MSA for information
regarding custom design applications for the Lynx Tripod anchorage connector.
6.0 PLANNING THE USE OF SYSTEMS
Do not use the Lynx Tripod unless a qualified person has inspected the workplace and determined that identified
hazards can neither be eliminated nor exposures to them prevented.
Prior to selecting a Lynx Tripod or other personal protective equipment, the user must make a workplace as-
sessment of hazards and conditions where the equipment is required. Such assessment must, at a minimum,
identify the presence of:
·Hot objects ·Chemicals ·Abrasive surfaces ·Climatic factors
·Sparks ·Electrical hazards ·Moving equipment ·Weather factors
·Flames ·Environmental contaminants ·Moving materials
·Unstable/uneven surfaces ·Heat-producing operations ·Sharp objects · Unguarded openings
·Slippery surfaces ·Confined space hazards
Foreseeable changes in any of these conditions, taken individually or collectively, must be identified, evaluated
and controlled. The materials and construction of the Lynx Tripod and associated equipment must be considered
in the selection process such that these workplace conditions are suitably addressed and responded to. The
equipment must match the work situation and workplace environmental factors.

P/N 10022053 Copyright © 2002, MSA
Page 10 USER INSTRUCTIONS LYNX TRIPOD
The workplace assessment must identify all paths of intended user movement and all hazards along such paths.
The user must identify the required range of mobility in each hazard zone and note the location and distance to all
obstructions in potential fall paths. Lateral obstructions which could be contacted in a pendular fall arrest must
be noted. An assembly connecting a harness to the anchorage must be selected which will satisfactorily limit
total fall distance and allow for dynamic elongation and activation distance of the assembly. If the Lynx Tripod
is to be used for confined space entry operations, the workplace assessment must comply with the requirements
of OSHA regulation 29 CFR 1910.146 and ANSI Z117.1.
6.1.1. LEG BASE CLEARANCE (INSIDE AND OUTSIDE)
Clearance between the position of the Lynx Tripod feet when erected and in working position and the access
through which the worker will be lowered shall be such that none of the Lynx Tripod legs will be positioned above
the access or be allowed to fall into the opening. Clearance between the working position of each of the Lynx
Tripod feet and the outside of the anchorage shall be a minimum of 3 ft (0.9 m) and shall allow unrestricted
movement of support personnel above during erection, use and compaction.
! CAUTION
Keep work area free from obstructions, trip hazards and spills which could impair
the safe operation of the Fall-Rescue Work System.
6.1.2 EXTERIOR CLEARANCE
AND INTERIOR HEADROOM:
There must be sufficient exterior clearance above
the anchorage to fully erect the Lynx Tripod. This
clearance, for each model, is given in section 1.1.
upon the system components (optional accessories)
that may be attached to the mounting pins of the Lynx
Tripod head. Refer to the User Instructions supplied
with each system component to determine the effect
on overhead clearance due to such installation.

USER INSTRUCTIONS LYNX TRIPOD Page 11
Copyright © 2002, MSA P/N 10022053
6.1.3 REQUIREMENTS FOR ADDITIONAL ANCHORAGES
AND ANCHORAGE CONNECTORS:
The Lynx Tripod is intended for use by a single person. Other personnel working in this immediate area as part
of a support team will require separate and independent safety systems depending on their purpose and work
function. Each person working in a given area must have systems provided to suit the hazards that may be
present. This determination must be made by a qualified safety engineer in accordance with sections 3 and 6
of these instructions, or corresponding sections of User Instructions from any optional components.
6.2 FREE FALL DISTANCE, TOTAL FALL DISTANCE,
AND SYSTEM ELONGATION:
Personal fall arrest systems must be selected and rigged to ensure that potential free fall distances will never
exceed 6 ft (1.8 m) as required by OSHA and ANSI Z359.1. [In Canada, free fall distance is limited to 5 ft (1.5
m) by regulation. ANSI A10.14 also restricts free fall distance to 5 ft (1.5 m)]. See separate instructions for con-
necting subsystems to determine the deceleration distance and dynamic elongation which must be allowed for
in the space of potential fall paths. Total fall distance is the sum of free fall distance and deceleration distance.
Dynamic elongation of the system (temporary elastic stretch of connecting components and subsystems) must
be added to total fall distance and clearance allowed.
6.3 CLEAR SPACE IN FALL PATH:
Make certain that enough clearance is available in all potential fall paths to prevent striking an object. The
amount of clearance needed depends upon the type of connecting subsystem used, and the location of the
anchorage or anchorage connector. Consult the manufacturer’s instructions for the particular connecting
subsystem or component for clearance needed.
1 Free fall distance. Limited to 6 ft (1.8 m) by OSHA and ANSI Z359.1. Limited to 5 ft (1.5 m) by
ANSI A10.14 and Canadian regulations.
2 Total fall distance. The sum of the free fall distance and deceleration distance.
3 Deceleration distance. Must not exceed 3.5 ft (1.1 m).

P/N 10022053 Copyright © 2002, MSA
Page 12 USER INSTRUCTIONS LYNX TRIPOD
6.4 RESCUE AND EVACUATION:
The user must have a rescue plan and the means at hand to implement it. The plan must take into account
the equipment and special training necessary to effect prompt rescue under all foreseeable conditions. If the
rescue is from a confined space, the provisions of OSHA regulation 1910.146 and ANSI Z117.1 must be taken
into account. Although a rescue plan and the means to implement it must always be in place, it is a good idea
to provide means for user evacuation without assistance of others. This will usually reduce the time to get to a
safe place and reduce or prevent the risk to rescuers. If the Lynx Tripod is to be included as part of rescue or
evacuation systems, the optional system components required (see section 4), the time required to erect the
Lynx Tripod and attach any optional components, and the anchorage requirements (see section 7.1) should
be considered when planning these systems.
7.0 USAGE
7.1 LYNX TRIPOD INSPECTION BEFORE EACH USE:
Inspect the Lynx Tripod to verify that it is in serviceable condition. Examine every inch of the Lynx Tripod for
severe wear, missing or broken elements, corrosion, or other damage. See section 11 for inspection details.
Do not use the Lynx Tripod if inspection reveals an unsafe condition.
7.2 ERECTING AND COMPACTING LYNX TRIPOD:
! CAUTION
Do not open the confined space access cover before completing installation of
the Lynx Tripod and all other system components.
7.2.1 ERECTING AND ADJUSTING THE ROPOD:
Step 1:
Tilt the ROPOD into an upright,
feet-down position.
Step 2:
Hinge each leg, one at a time, into the outward
and locked position. You will note that each leg
automatically snaps upwardly when the hinge locks.
Check to be certain of hinge locking.
! CAUTION
Potential pinch point. DO NOT touch tripod leg
within six (6) inches of the tripod head.

USER INSTRUCTIONS LYNX TRIPOD Page 13
Copyright © 2002, MSA P/N 10022053
Step 3:
Position the feet about the hatch cover in
accordance with work area geometry and
surface conditions.
Step 4:
Optional components such as the Split-Mount Pulley
or the Dynevac with leg-mount bracket should be
assembled to the LynxTripod at this time. Follow the
appropriate user instructions for each optional
component that is to be connected to the Lynx
Tripod.
Step 5:
Raise the LynxTripod one leg at a time by pulling
the positive-locking pin (attached to the upper leg
section), incrementally sliding out the lower leg
section, and repinning. Repeat for each leg un-
til the Lynx Tripod head is at the desired height.
Each leg may be extended to different lengths to
accommodate variations in surface elevation.
The LynxTripod head should be horizontal when
installation is complete. Be careful not to
extend each leg too far in each increment so
as to cause the Lynx Tripod to topple.

P/N 10022053 Copyright © 2002, MSA
Page 14 USER INSTRUCTIONS LYNX TRIPOD
Step 6:
Once at the proper height, check to be sure the
Lynx Tripod is stabilized and plumb. Feed the
stabilizing chain through the chain connector at
the base of the Lynx Tripod legs and continue to
adjust the legs to the proper height. Some final leg
length adjustment may be necessary to properly
distribute the load to each leg. Check all leg pins to assure
secure fastening and set the feet in either the tread-down
or spike-down position (according to anchorage surface
conditions). Tighten the chain through all connectors, bring
the last link of one end of the chain and the closest link
available at the other end of the chain and fasten using
When all equipment is in place on the Lynx Tripod, make a last check for plumbness, foot traction and stability.
Make final adjustments. On uneven terrain it may be necessary for the “downhill” leg(s) to be extended farther
to stabilize the Lynx Tripod by equalizing the weight borne by each leg. On uneven terrain it is better to have
optional equipment such as the Lynx Rescuer or Lynx Hoist mounted on the “uphill” legs for greater stability.
The Lynx Tripod head should be horizontal when installation is complete.
Now remove the hatch and manhole cover. For a descriptive brochure on MSA implements to assist in manhole
cover removal, contact MSA.
7.2.2 COMPACTING THE LYNX TRIPOD:
To compact the Lynx Tripod for transport or storage, reverse the setup procedure. To disengage the leg
hinge locks, pull down on the leg and hinge it inward. Attach Lynx Tripod legs together securely with lower
strap as shown. After use, return the Lynx Tripod to the proper person and place for cleaning and storage as
described in section 9.
7.3 MAKING PROPER CONNECTIONS
7.3.1 USE OF ATTACHMENT PINS:
The Positive Locking Pin is used to mount the optional MSA Split-Mount Pulley P/N 506222, and may also be
used to connect directly with a MSA Carabiner. The Split-Mount Pulley is designed to work in conjunction with
a Lynx Rescuer, where the cable of the Lynx Rescuer would pass through the Side-Mount Pulley and descend
into the center of the work access. The MSA Carabiner may be used as an intermediate connector for system

USER INSTRUCTIONS LYNX TRIPOD Page 15
Copyright © 2002, MSA P/N 10022053
components, such as the MSA Fallbloc Lifeline. The Hitch Pin is used to mount the optional Lynx Boom Hoist.
See section 7.5. Contact MSA for information about connection of optional components to the Lynx Tripod or
refer to the separate User Instructions provided with each component.
7.3.2 MAKING CONNECTIONS:
When using a snaphook to connect to an anchorage or when coupling components of the system together,
be certain accidental disengagement (“rollout”) cannot occur. Rollout is possible when interference between
a snaphook and the mating connector causes the snaphook’s gate or keeper to accidentally open and release.
Rollout occurs when a snaphook is snapped into an undersized ring such as an eye bolt or other non-compatibly
shaped connector. Only self- closing, self-locking snaphooks and carabiners should be used to reduce the
possibility of rollout when making connections. Do not use snaphooks or connectors that will not completely
close over the attachment object. Do not make knots in a lanyard. Do not hook the lanyard back onto itself.
Snaphooks and carabiners must not be connected to each other. Do not attach two snaphooks into one D-
ring. Do not attach a snaphook directly to a horizontal lifeline. Always follow the manufacturer’s instructions
supplied with each system component. Refer to Section 2 of these instructions.
7.4 INSTALLATION OF SIDE-MOUNT HOIST & LYNX RESCUER
TO LYNX TRIPOD
To install the side-mount hoist, follow the instructions below and refer to Figure 11.
Step 1: In accordance with the tripod instructions, raise the tripod only to a height where the tripod head is
easily reachable by the installer.
Step 2: Mount the pulley bracket P/N 506473 (A) to the top of the tripod leg (B) to the LEFT of the Lynx Rescuer/
Dyna-Lock mounting leg with green label. Pin the bracket in place with the ball lock pin (C).
Step 3: Place the hoist to the right side (when facing the leg) of the leg to which the pulley bracket is mounted,
and extract approximately 9 ft (2.7 m) of line (D). Attach the pulley (E) to the pulley bracket (A) with
the clevis pin (F). Secure the clevis pin with the hairpin cotter (G). Note: The hoist snaphook must
hang to the interior of the tripod.
Step 4: If using a fall arrester that’s leg-mounted to the tripod (ie: the Lynx Rescuer, Dynevac II, or Dyna-Lock
retractable lifeline) it is attached to the leg with the green labels. Lay the fall arrester on the ground
next to this leg. Extract sufficient fall arrester line and reeve the line over the split-mount pulley, P/N
506222. Pin the pulley in the head of the tripod using the attached ball lock pin. See step 4 of section
7.2.1.
Step 5: Raise the tripod to the desired working height.
Step 6: Insert the tripod leg pin (H) for the leg to which the hoist will be mounted partially through the tripod
leg, starting from the left side of the ouside face of the leg. See Figure 11.

! CAUTION
Be sure to insert the tripod leg pin (H) completely through the tripod leg and hoist
housing.
Step 7: Insert the ball lock pin (J) through the holes (K) at the top of the hoist mounting bracket and behind
the tripod leg.
Step 8: If using a leg-mounted fall arrester, mount that product to the tripod leg with the green instruction
label using the mounting bracket, P/N 506216 & 506232. Pin the borrom pin of the bracket through
one of the holes in the lower leg of the tripod. The upper pin of the bracket pins on the inside face
of the Tripod leg. For most applications, it is ergonomically preferrable to mount the fall arrester at
waist level.
Step 9: Install the tripod leg base chain and check to be sure the tripod is stabilized and plumb. Some final
leg length adjustment may be necessary to properly distribute the load to each leg. Check all leg pins
to ensure secure fastening. Set the feet in either tread-down or spike-down position, according to the
condition of the surface on which the tripod rests.
Step 10: With all equipment now in place on the tripod, make final adjustments and last check for plumbness,
foot traction, leg base chain tautness and stability. On uneven terrain, it may be necessary for the
“downhill” leg(s) to be extended to stabilize the tripod by equalizing the weight borne by each leg. On
uneven terrain it’s better to have the Lynx Rescuer and Lynx Hoist mounted on the “uphill” leg(s) for
greater stability.
7.5 INSTALLATION OF BOOM-MOUNT HOIST TO TRIPOD
To install the boom-mount hoist to the tripod, read the following instructions and refer to Figure 12.

7.6 INSTALLATION OF LYNX RESCUER TO LYNX TRIPOD
The LYNX RESCUER may be used in many different system arrangements for fall arrest and emergency
retrieval. Most of these systems require special engineering design, testing, controlled installation and su-
pervised training and use in order to be safe. MSA has developed a system offered as part of its product line
which does not require special engineering to be put into use. This is the FRWS (Fall-Rescue Work System)
utilizing the Lynx Tripod (portable tripod). This system, nevertheless, must be cautiously applied under the
supervision of a competent person.
The Lynx Tripod portable anchorage connector system facilitates access to confined spaces with topside
openings such as manholes. The Lynx Hoist provides personnel and materials lifting and lowering while the
Lynx Rescuer provides backup fall arrest, which is further backed-up by the Lynx Rescuer’s built-in emergency
rescue mechanism. Use of leg mounting of both the Lynx Rescuer and Lynx Hoist lowers the system’s center
of gravity by adding their weights to lower sections of the Lynx Tripod, which reduces the Lynx Tripod toppling
hazard. Leg mounting also permits topside workers and rescuers to operate the Lynx Tripod and Lynx Hoist
at waist level and away from the hatch opening.
In the complete FRWS, a worker in a full body harness can be
attached to the Lynx Rescuer for fall protection. The Lynx Rescuer
is mounted on a Lynx Tripod leg and the Lynx Rescuer working line
is reeved over the Split-Mount pulley attached at the Lynx Tripod
head. The user can then be seated and strapped into a suspension
seat which is attached to the Lynx Hoist snap hook. Lynx Hoist is
mounted on another Lynx Tripod leg and its extension tube with
hook end is connected at the Lynx Tripod head. With Lynx Tripod
positioned over a hatch opening, the worker seated in the suspen-
sion seat can be lowered by the Lynx Hoist. See separate User
Instructions for information regarding the Lynx Hoist.
If the suspended worker intentionally leaves the suspension seat
at the floor of the confined space, he will remain connected to the
Lynx Rescuer at the fall arrest D-ring on the harness. The Lynx
Hoist is therefore free to lower and lift materials and equipment
to and from the downside worker’s elevation. When not in use
for materials handling and personnel transport, the Lynx Hoist is
available for rescue of downside workers (one at a time). If the
downside worker falls (or is overcome) while connected to the Lynx
Rescuer, his fall is arrested and the Lynx Rescuer’s emergency
rescue mechanism can be activated topside for retrieval.
8.0 CARE MAINTENANCE AND STORAGE
8.1 CLEANING INSTRUCTIONS:
Clean the Lynx Tripod with a solution of water and mild laundry detergent. Dry hardware with a clean cloth. Do
not speed drying with heat. Excessive accumulation of dirt, paint, or other foreign matter may prevent proper
function of the Lynx Tripod and, in severe cases, weaken the material and joints. Questions concerning Lynx
Tripod conditions and cleaning should be directed to MSA.
8.2 MAINTENANCE AND SERVICE:
Equipment which is damaged or in need of maintenance must be tagged as “UNUSABLE” and removed from
service. Corrective maintenance (other than cleaning) and repair, such as replacement of elements, must be
performed by the MSA factory. Do not attempt field repairs.

8.3 STORAGE:
Store the Lynx Tripod in a cool, dry and clean place. Avoid areas where heat, moisture, oil, and chemicals
or their vapors or other degrading elements may be present. Equipment which is damaged or in need of
maintenance should not be stored in the same area as usable equipment. Heavily soiled, wet, or otherwise
contaminated equipment should be properly maintained (e.g. dried and cleaned) prior to storage. Prior to
using equipment which has been stored for long periods of time, a Formal Inspection should be performed by
a competent person. See section 12.
9.0 LABELS AND MARKINGS
9.1
The following labels must be present, legible and securely attached to the Lynx Tripod. The Formal Inspection
Grid must be punched with a date (month/year) within the last six months. If not, remove the Lynx Tripod from
use and mark it as “UNUSABLE” until a Formal Inspection is performed in accordance with section 12. See
section 4 for location of labels.

9.0 INSPECTION BEFORE EACH USE
9.1 INSPECTION FREQUENCY
The Lynx Tripod Fall-Rescue Work System must be inspected by the user before each use. Additionally, the
Lynx Tripod must be inspected by a competent person other than the user at intervals of no more than six
months. The competent person inspection is referred to as Formal Inspection.
If the Lynx Tripod has been subjected to fall arrest forces, it must be immediately removed from use and
marked as “UNUSABLE” until subjected to a Formal Inspection and approved for use by a competent person
inspector.
9.2 PROCEDURE FOR INSPECTION BEFORE EACH USE
Step 1: Inspect the Lynx Tripod labels to verify that they are present and legible. See section 4 for location of
labels. See section 10 for the specific labels that should be present and the information contained on
them. Check the Formal Inspection Grid to be sure a Formal Inspection has been performed within
the last six months. If the Grid does not indicate that a Formal Inspection has been performed within
the last six months (by being punched), or if any labels are missing or illegible, remove the Lynx
Tripod from use and mark it as “UNUSABLE” until a Formal Inspection is performed by a competent
person.
Step 2: Inspect head assembly for corrosion, broken or cracked welds, deformation, fractures, cracks, altered
or missing elements, burns, and heat and chemical exposures.
Step 3: Inspect all metallic parts (i.e. head, legs, leg pins, attachment pins, feet, leg base chain) for deforma-
tion, fractures, cracks, corrosion, deep pitting, burrs, sharp edges, cuts, deep nicks, missing or loose
parts, improper function, and evidence of excessive heat or chemical exposures.
Step 4: Inspect all non-metallic parts (i.e. skid-resistant foot pads and labels) for cut, broken, excessively worn,
missing and loose parts. (Labels are to be additionally checked in accordance with Step 1 above.)
Inspect for evidence of burns and excessive heat and chemical exposures.
Step 5:Check the function of the Lynx Tripod legs. Legs should move smoothly in the leg pockets and should
seat firmly when moved to the fully open position. The lower legs should slide smoothly within the
upper legs along their entire length. Lynx Tripod feet should pivot easily and remain flat on the ground
when the Lynx Tripod is erected.
Step 6: Inspect each component and subsystem of the complete system in accordance with the associated
manufacturer’s instructions. See section 6 for a description of the make-up of the different system
types.
9.3 CORRECTIVE ACTION
When inspection in accordance with section 11.2 reveals signs of inadequate maintenance, the Lynx Tripod
must be immediately removed from service and marked as “UNUSABLE” until destroyed or subjected to
maintenance by the user’s organization in accordance with section 9. Defects, damage, excessive wear and/or
aging are generally repairable by the factory. If detected, immediately remove the Lynx Tripod from use and
mark it as “UNUSABLE” until repaired. For final disposition, submit the Lynx Tripod to a competent person
who is authorized to perform Formal Inspection. If there is any question as to repairability, contact MSA or a
service center authorized in writing by MSA before further use of the Lynx Tripod.
