USING THE AZ VORTEX
Assembly of the AZ VORTEX
It takes at least two people to assemble the AZ VORTEX and is easier with more. Installing
the AZ VORTEX at ANY edge without handrails requires the use of Travel Restraint within the
Hazard Zone. There are two ways to assemble the AZ VORTEX:
1) Build in place. This allows easier movement but individual sections must be supported
and belayed until the assembly is complete. Assemble as much as possible, such as each
head piece to a leg, before moving into position.
2) Build it away from the edge and then walk it out as one unit to the edge. This may require
three to four people to move it into place but only requires a single Tether Line for safety.
Sometimes a combination of both ways works well, but remember that it is difficult to change
pins at the head while standing on an edge by a large drop. Make these changes back from the
edge and then move the AZ VORTEX into position and tie down the feet only after making your
final changes. Several attempts at getting it right may be needed before tie down commences.
This process will become less cumbersome with experience.
Each method has advantages and disadvantages depending on the location and the
available personnel. Practicing both will prepare the team to select the best option under difficult
set up positions.
Always attach a Tether Cord to the individual sections or to the entire unit until the AZ
VORTEX is secured. Tether Cords should be belayed on a separate anchor to prevent the AZ
VORTEX from toppling over during installation. The Tether Cords can be left in place during the
operation for later disassembly.
Never leave an unsecured AZ VORTEX unattended.
Support each leg section until the unit is secured to prevent toppling during set up. As in any
rigging situation, one person should be in charge of the set up and communication should be
deliberate and precise.
Disassembly of the AZ VORTEX
Disassembly of the AZ VORTEX is less problematic. With adequate personnel on travel
restraint devices, remove the anchoring at each foot and carry the entire device back out of the
hazard zone for disassembly. Again, the Tether Cord should be in place during this movement
away from the edge. Once the AZ VORTEX is well away from any hazard, it may be taken
apart, inspected for any damage, and stowed in its proper storage compartments.
