4.1 General Installation Requirements: The tripod is designed for confined space entry and egress, fall protection, rescue and evacuation, and
material handling. The user must perform specific job hazard analyses in accordance with OSHA regulations. Mitigate hazards in accordance with
OSHA guidelines.
The tripod is most efficient when used at its maximum working extension height.
Ensure the installation surface is solid, free of loose sand, gravel, anything that might compromise footing. For more information on confined space
practices and procedures, see Appendix C of this manual.
4.2 First Time Pre‐Use Assembly: This step installs the device brackets. Once the brackets are installed, removal is unnecessary. Remove all
components and pieces from the packing materials. Place the tripod on a work bench or on a flat surface.
Stand the tripod up, spread the legs out until all three head locking detent balls in the legs click into the holes in the head assembly. Refer back to
Figure 1A. Note that the leg length adjustment pins will be in the transit/storage holes, approximately 14" below the head assembly. These holes
are for storing the pins during transit and storage. Remove the pin from one leg. Extend that leg to the first adjustment hole and insert the pin.
Repeat on the other two legs.
The tripod is at approximately half its working height, to facilitate bracket installation.
4.2.1 Install The Device Brackets: The tripod is designed to use up to three device brackets. Bracket part number 7291B is the compatible bracket.
Note on the head assembly the two pulleys at the top of two legs. The brackets install on one or both legs. To install a third bracket, an additional
pulley is required. Find the bracket components. Fit the components for one bracket to one leg at approximately the bottom edge of the black and
yellow safety tape. See Figure 3. Ensure the stationary device locking bar is at the bottom. Insert the bolts, place a lock washer on each one, thread
the nuts on and tighten securely. Ensure the bracket is installed on the outside of the leg(s).
Fit the remaining bracket(s) to line up to a head pulley and tighten the nuts. Device bracket installation is complete.
Remove the leg securing detent pins from the legs, retract the legs all the way and put the pins into the storage location. Disengage the detent
balls in the head assembly and put the legs together. Place the tripod in the provided carrying bag.
4.3 Tripod Set‐up: Remove the tripod from the carrying bag. Before each use, inspect the tripod and ensure it is in proper working order, in
accordance with the inspection procedures in Section 7 of this manual.
Stand the tripod up, near or over the confined space entry point. Use caution. Avoid stepping, falling, or dropping tools or parts into the confined space.
Spread the legs out until all three head locking detent balls in the head assembly click into the holes in the legs.
Remove one leg securing detent pin from its storage location, extend that leg to its first adjustment hole and insert the leg securing detent pin.
Repeat with the remaining legs. The tripod is at approximately half its working height, to facilitate device installation, as shown in Figure 4.
NOTE: Leg height may be adjusted to accommodate uneven surfaces or raised edges. Before attaching the entrant to the leg end connector, ensure
the tripod is straight upright, and the head assembly is level, as shown in Figure 8.
4.3.1 Install the Winch/Devices: This step installs the device(s) on the tripod. The winch and device should have one half of the mating bracket
already installed.
Place the winch/device bracket onto the leg bracket. Ensure the mating slots on the winch/device bracket engage the leg bracket rod as shown in
Figure 5A and 5B. Align the top holes, and insert the integral device securing detent pin.
Remove enough cable from the device(s) to drop the leg end connector down through the tripod head assembly to the working surface. Slip the
cable under the cable retainer as shown in Figure 6.
4.4 Use of the Tripod: Ensure the tripod is centered over the confined space opening, and that the attendant and entrant, or any personnel
involved in a rescue, would not inadvertently step into the confined space opening during normal operation or in a rescue situation.
Ensure the feet are deployed to the proper application for the surface, i.e., on the rubber pads for firm surfaces. Flip the feet up and out to deploy
the teeth for loose, shifting, or soft surfaces.
With the devices installed, extend the legs to raise the tripod height. Remove the leg securing detent pin on one leg extend that leg out until the leg
locking detent ball clicks into place, as shown in Figure 4. Insert leg securing detent pin in the leg. Repeat with the two remaining legs.
Pass the leg securing chain through the eye bolts at the bottom of the legs, take up as much slack as possible, and fasten with the threaded link to
prevent the legs from spreading due to a fall arrest event. See Figure 4.
WARNING
Ensure the leg securing detent pins are inserted through the appropriate holes in the tripods legs, and the detent ball pins are properly inserted.
The device should be at a comfortable height for use. Adjust device bracket if necessary. The leg end connector for the device should be within
reach.
4.5 Install Additional Fall Protection Devices: The eye bolts under the head assembly are for additional devices such as SRDs, a Fall Arrestor
Connecting Subsystem (FACSS), or a rope rescue system. See Figure 7. Do not use winch or 3‐Way SRL‐R device cables in a secondary pulley
installed in eyebolts. Winch and device cables must be installed in the pulleys on the head assembly. The tripod is normally equipped with two
pulleys in the head assembly, with an option for a third. Ensure the brackets are installed on the outside of the leg(s).
4.6 Connect to the Device: Grasp the device leg end connector, keep the line taut, and wind enough cable from the device to connect to the dorsal
D‐ring of the entrant's full body harness.
Ensure working lines are free of entanglement and contact with sharp edges. Avoid swing fall. Use of the tripod for suspension or personnel riding
requires a back‐up fall protection system. The tripod discussed in this manual is equipped with provisions for a back‐up fall protection system.
Fall protection applications require the user to meet OSHA requirements. Ensure the working surface will support fall protection loads. See Section
3. Fall protection systems must include a FBH as the body wear component. A typical PFAS would include a FBH, a connecting subsystem or
component (SRL or lifeline and a rope grab) and approved connectors to connect the system together. Position the entrant for entrance into the
confined space. For additional information on using the devices, consult the manufacturer's user instruction manual supplied at time of shipping.
4.7 Dismantle the Tripod: To dismantle the tripod, reverse the order of set‐up.
Store in the bag provided.
For additional information on confined space, see Appendix C of this manual.
