Roco QUICK DRILL #8 - Petzl ID

Maintain Proficiency with Ground Station Drills

The Petzl ID is a great device. However, as with any device or technique, if you don’t practice, you risk forgetting some of the basic principles and functions involved in its proper use. Using quick and easy-to-set-up ground stations will help to keep proficiency levels up while reducing risk, logistics, and time required.

Here are some drills and ground station ideas that will help the Petzl ID operator stay proficient. Keep in mind, these hands-on ground stations can often be applied to other devices and techniques as well – not every training session requires suspending rescuers!

Station Set-Up

Choose a solid anchor at ground level with about 10 feet of space to move and pull rope. This can be done in a classroom, apparatus bay or other area since the drill is about proficiency in using the ID and its different functions.

Taking-in Slack “TENSION”

Have the participant load and anchor the device as a lower. Pull at least 5-to-10 feet of slack out of the device and have participant pull the slack out of the system through the device as if setting a plumb point.

Have the operator stand in front of the ID, facing the anchor. Hold the two ends of the rope in front of the device and close together. This will prevent the safety cam from grabbing the rope while the participant strips rope on the standing end of the device (the 11 O’clock) to take-in (tension) slack.

Remember, taking in slack (tensioning) is also important when starting a Z-rig haul as the system may not automatically start stripping/cleaning the rope through the device if it should be locked. In this case, the load would not be captured and any progress gained would be lost or dropped if the haul team let go of the haul line. This may also occur initially with a 5:1 Z-rig, even if the device is unlocked, until the full load is on the system.

Giving-out Slack “SLACK”

To give out (or feed) slack, have the operator remain in the descent control position (behind the device). Keeping the device with the top or bottom plates facing the ground, simply use the left hand to turn the body of the ID perpendicular to the direction of the load travel as rope is pulled with the right hand from the 7 O’clock position of the ID. Simulate adjusting a plumb point or feeding slack once a lower is complete and the patient is on the ground.

Rappel Ground Exercise

Have participants anchor the rope for a rappel and attach the ID to the rope and their harnesses. Have them lean away from the anchor and walk backwards while using the device to control speed. Review hand and body positions and have operators pull the ID into panic mode and reset. Direct participants to let go of the rope in order to build confidence in the automatic braking of the device. Also, have them practice tensioning and feeding slack (adjusting rappel plumb point) while in the rappel mode.

This drill may seem too simple to be of any benefit, but how many of us have watched our teammate fumble with loading, or fumble while trying to adjust the tension or give slack on an anchored ID? The more hands-on time operating this device, the better! Practicing a technique at ground level will help rescuers be more proficient when they “live load” a system during training, or when performing a real rescue.

Roco QUICK DRILL #7 - Anchor Selection and Rigging

Wednesday, April 08, 2015

Maintaining proficiency when building rescue systems requires skills and experience – that’s why regular practice is critical!

With continued practice in keeping it safe and simple (KISS), rescuers can learn to be more efficient with their equipment as well as in selecting and setting up rigging anchors. Proficiency with this allows them to get a running start in constructing the foundation of all rescue systems.

1.  Use an area that has a variety of simulated anchor opportunities. Try to create a mix of bombproof, substantial, and inappropriate anchors.

2.  Clearly state the objectives and point out exactly where the lines have to fall in terms of plumb line, and whether it’s to be set up as a lowering system, safety line belay or static line (rappel line).

3.  Have a variety of anchoring material and equipment available, such as utility straps, webbing, extra rope shorts, carabiners, tri-links, etc. Lay out limited amounts of this equipment.

4.  Here are the rules:
  • • For each rotation, define the type of system to be built (lowering, static or belay) and the type of anchor system such as: bombproof, substantial (multi-point) or self-equalizing.
  • • After each rotation, participants must give up a piece of equipment they used (i.e., if they used utility belts as anchors, remove the belts from available equipment for the next rotation).
  • • Repeat as many times as participants can come up with solutions as you switch between anchor types, systems and available equipment.

5. With a little planning, you can come up with an order and number of rotations possible along with an equipment list that should end with just the rope and a device. This drill can be adjusted to help newer team members better understand rigging principles and techniques, or to challenge more experienced team members based on the number and type of rotations and equipment available.

6. Another way to challenge more experienced team members is to limit the knots to be used by providing a master list of knots. Then, eliminate a knot from the list after it has been used.

This drill will help new rescuers better understand their options while taking a good anchor rigger to the next level.

Roco QUICK DRILL #6 - Splitting One Rope Between Two Systems

Wednesday, January 28, 2015

At times, it may be necessary to use a single rope split between two different rescue systems. This can be useful when all ropes are being used for other purposes, such as taglines, extending anchors, etc. Being proficient in using a single rope between two systems helps spread the resources and may be more than just another tool in your toolbox. Someday, it could be crucial to a successful rescue!

Here’s the drill:

1.  Choose an elevated location that is less than one half the length of the rope – plus, allow a good margin of extra rope. For example, if using a 150 ft. rope, you could use a platform that is about 40 feet high.

2.  Select two appropriate anchor points near each other. One will be for the main line; the other for the safety.

3.  Build a lowering system using one end of the rope and the main line anchor. Anchor the descent control device and prepare for a lower.

4.  Build your safety line using the other end of the rope and the second anchor.

5.  Lower the rescuer, package your patient, and recover them both.

6.  Try doing this using different descent control devices and different types of systems (piggy back vs. Z-rig). Play "what if" and problem solve.


Tips/Hints:

•  Pre-measure your lines. We say start where you want to end up! This drill is nothing more than lowering the end knots to the ground to assure you have enough rope to do the lower. It also allows you to inspect the rope for damage before life loading the lines.

•  If you do this with both ends of your rope and you have enough rope to reach from the ground to your two anchor points independently, you now know you have enough rope for both the mainline and safety line system.

•  Any additional line left between the two systems can be used to extend anchor points, rigging or build mechanical advantage systems.

•  Many times we use this technique of splitting rope from a single rope bag as our safety/retrieval line for rescue entrants during confined space rescue. We use rope bags that allow us to work from either end of the rope easily. We take two different color ropes usually 125 ft., tie them together, and load the bag from both ends with the knot in the middle (double fisherman). This allows us to run safety lines to two rescuers out of one bag. Since each rope is a different color it helps with line management, communications, identification and emergency retrieval. If your rescue scenarios require entrants to advance more than 125 ft., then longer ropes can be substituted. The rope can also be used as a single 250 ft. safety line provided you have knot passing capabilities.

  • •  Manage your ropes! Without good rope management, your work area can easily turn into a tangled mess.

This drill forces rescuers to think ahead and “outside the box” in order to allocate appropriate lengths of rope for each system or how to better use limited equipment resources. It is an excellent exercise in efficiency, rope management, and housekeeping – while demonstrating the importance of each when managing this type of system.

Roco QUICK DRILL #5 - Building Complete Rescue Systems

Thursday, October 16, 2014

Due to time restraints in refresher training, oftentimes individual team members may only get to build a portion of a rescue system – for example, setting up a mainline or performing patient packaging. In order to have maximum team efficiency, it is important to keep all team members proficient in all aspects of the rescue operation.

1. Lay out enough equipment to build a mainline and a safety line system and for a particular type of packaging. Describe which system is to be used and how the patient will be packaged (i.e. vertical stokes raise, or horizontal SKED lower with attendant).

2. Identify what will be used as anchors. If working in a classroom or apparatus floor, a chair leg could be designated as bombproof or substantial anchor depending on the rigging the team member is being asked to do. If you are in the field, use whatever anchors are available.

3. Assign a team member to construct or rig the entire system on their own, including packaging the patient.

This drill allows a Team Leader to identify potential weaknesses in individual performance skills, while improving the team member's understanding of how the systems work. The knowledge gained will also help in planning future training sessions to correct any deficiencies. For the individual team member, this drill will reinforce all aspects of putting systems together and identifying weak points or areas of confusion that need to be corrected.

Roco QUICK DRILL #4 - Selecting the Proper Knot and Tying Correctly

Wednesday, August 13, 2014

Being able to tie a knot in the classroom with a rope short vs. selecting the proper knot and tying it correctly in the field during an emergency requires experience. With a little imagination, you can provide your team members numerous scenarios to practice in just a short period of time while they are still within a controlled environment. This practice will help them to gain more experience that should pay off in the long run if needed during a real life emergency.

1.  Identify the knots your team uses, and where they are used in various systems.

2.  Lay out a series of applications where team members would need to tie a knot. Decide in advance what knots are acceptable in these applications since many times more than one knot may get the job done.

3.  Once you have established the acceptable knots, lay out a gauntlet of knot tying stations.

4.  Each team member will go through each station... first, deciding which knot to use, and then tying it as it would be used in the application (examples: end knot in a lower line, vertical bridle knot, lashing a backboard, adjustable anchor, self-equalizing anchor, etc.)

The goal is to have team members choose an appropriate knot, tie it correctly, and apply it properly based on the rescue system presented. Two examples for knot stations are: (1) Backboard lashing - have the lashing complete except for the knot at the end; and (2) Mainline rigged except for the knot attaching it to the anchor.
