INSTRUCTIONS FOR USE
1. Function and Application: The MSA Workman Tripod head is aluminum alloy and legs are high-tensile, aluminum alloy. The Tripod conforms to standard EN 795-
2012 class B and meets requirements of Customs Union Technical Regulation "Safety of Personal Protective Equipment" TP TC 019/2011, the Ukrainian "Technical
Regulation for Personal Protective Equipment" and DSTU EN 795:2006 Standard. The Tripod is a transportable temporary anchor device of a personal fall arrest
and rescue system. It may be used for fall arrest, rescue, retrieval, evacuation, depending on which attachment elements are included. The MSA Workman Tripod
is designed for use by one person with a combined total weight no greater than181 kg, including clothing, tools, and other user-borne objects. This capacity is in
conformity with EN795. When the MSA Workman Winch is assembled on the MSA Workman Tripod as described in the next section, this configuration is suitable for
lifting, lowering, and positioning either personnel with a maximum weight of 140 kg., or materials with a maximum weight of 225 kg. These applications and capacities
are in conformity with the Directive 2006/42/EC on machinery. When the tripod is used as part of a fall arrest system, the user shall be equipped with a means of limiting
the maximum dynamic forces exerted on the user during the arrest of a fall to a maximum of 6 kN. Never use the Workman Tripod to lift, lower, or position personnel
and materials at the same time. Figure 32 show configurations of optional accessories and typical applications of these systems.
2. Use of MSA Workman Tripod attachments: (1) The side-mount swivel eyes (FIG 6) are to be used for personal fall arrest systems, such as a flexible anchor line
(EN353-2, DSTU EN 353-2:2006, TP TC 019/2011), an RTFA (Retractable Type Fall Arrester), or a Rescue RTFA. Refer to the separate user instructions included with
these products for installation and use of each of these optional components. (2) The center swivel eye is used to attach accessories such as the MSA Split-Mount
pulley, P/N 506222, for MSA Workman Winch (FIGS 4&7). If the center swivel eye is not used for the MSA Workman Winch, then the center swivel eye can be used
to attach a flexible anchor line, RTFA, or Rescue RTFA. (3) The MSA Rescue RTFA and Workman Winch are mounted to the Tripod in conjunction with the MSA Split-
Mount pulleys, P/N 506222, and carabiners, P/N 10129888. (4) The MSA Rescue RTFA and Workman Winch attach to the Tripod by means of integral leg mounting
brackets. (5) There is one positive-lock pin in each extension leg. Each pin is inserted through the selected holes in the upper and lower legs when the desired leg
extension is achieved. The button on the end of the pin must be depressed and held while the positive-lock pin is inserted or removed from the tripod (FIG 8). The
MSA RTFA or Rescue RTFA can also be mounted directly to a side-mount swivel eye using a carabiner certified to EN 362. The load capacity of a Rescue RTFA when
mounted directly to the side swivel eye of the MSA Workman Tripod is 140 kg. (6) The leg base strap is necessary to maintain the position of the Tripod legs and to
distribute the applied loads during system use (FIG 52).Tripods have attachments at the base of each lower leg, through which the leg base strap is threaded. It is fully
assembled when the end is passed through all three attachments, connected through the cam buckle, and tightened. (7) The leg strap may also be connected to the
head of the tripod using a carabiner, and used as a carrying strap (FIG 9). (8) The nylon tote bag is used to protect the Tripod during transport and storage (FIG 10).
(9) Carabiner, P/N 10129888, is used to mount the optional MSA Split-Mount pulley P/N 506222 to the side attachment points on the Tripod head. (10) The Split-Mount
pulley is designed to work in conjunction with a Rescue RTFA or MSA Workman Winch, where the cable of the Rescue RTFA or MSA Workman Winch would pass
through the Split-Mount Pulley and descend into the center of the work access (FIG 3). (12) Contact MSA for information about connection of optional components to
the Tripod or refer to the separate user instructions provided with each component.
3. Operating Instructions: It is the responsibility of the user of MSA Workman Tripod to assure that they are made familiar with these user instructions and trained by
a competent person. Ensure that you have been adequately trained in the use of this MSA Workman Tripod and make sure that you fully understand how it works.
4. Operating Procedure: Do not open the confined space access cover before completing installation of the Tripod and all other system components. Erecting and
adjusting the tripod (FIGS 13-18): Step 1: Tilt the Tripod into an upright, feet-down position. Step 2: Hinge each leg, one at a time, into the outward and locked position.
Note that each leg automatically snaps upward when the hinge locks. Check to be certain of hinge locking. Step 3: Position the feet about the hatch cover in accordance
with work area geometry and surface conditions. Refer to 6. Design Statements: section 4 for clearance requirement. Step 4: Optional components to be attached to the
Tripod head, such as the Split-Mount pulley, should be assembled to the Tripod head at this time. Follow the appropriate user instructions for each optional component
that is to be connected to the Tripod. Step 5: Raise the Tripod one leg at a time by pulling the pin (attached to the upper leg section), incrementally sliding out the lower
leg section, and repinning. Repeat for each leg until the Tripod head is at the desired height. The Tripod head should be level when installation is complete. Be careful
not to extend each leg too far in each increment so as to cause the Tripod to topple. The Tripod legs must not be pulled out more until the maximum mark, see FIG 8.
Step 6: Once at the proper height, check to be sure the Tripod is stabilized and plumb. Feed the leg base strap through the feet at the bottom of the Tripod legs. Check
all leg pins to assure secure fastening and set the feet in the tread-down position. Tighten the strap through all connectors by pulling the loose end of the web through
the cam buckle. When all equipment is in place on the Tripod, make a last check for plumbness and stability. Make final adjustments. Then, remove the hatch and
manhole cover. To compact the 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 Tripod legs together securely with lower strap as shown (FIG 18).
5. Inspection Guidelines: Step 1: Inspect the Tripod labels to verify that they are present and legible. Check the formal inspection grid to be sure a formal inspection
has been performed within the last 12 months. If the grid does not indicate that a formal Inspection has been performed within the last 12 months (by being punched),
or if any labels are missing or illegible, remove the 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, cracks, deformation, fractures, 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) for deformation, 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, labels, and leg
base strap) for cut, broken, excessively worn, missing and loose parts. Inspect for evidence of burns and excessive heat and chemical exposures. Step 5: Check
the function of the 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. Tripod feet should pivot easily and remain flat on the ground when the Tripod is erected. Step 6: Inspect
each component and subsystem of the complete system in accordance with the associated manufacturer's instructions. Detailed inspections must be recorded in the
inspection checklist. After inspection, mark or punch out the inspection tag to indicate a complete formal inspection was completed.
6. Design Statements: (1) The surface (anchorage) where a Tripod is installed should be inclined by no more than 152 mm over a distance of 3 m. Any incline greater
than this amount 2.8° could allow the Tripod to slide or tip over.
(2) The strength of the ground (base, floor) when the Tripod will be placed shall be not less 10 KN. The 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.
