DAY 1 OBJECTIVES
  • 1. The student will be able to tie the
    following knots.
  • a. Figure-eight stopper.
  • b. Figure-eight on a bight.
  • c. Figure-eight follow-through.
  • d. In-line figure-eight.
  • e. Overhand bend.
  • f. Square bend.
  • g. Double overhand bend.
  • h. Prussik hitch.
  • I. Bowline.

4
OBJECTIVES CONT.
  • 2. Properly tie rescuer harness and attach to a
    safety line.
  • a. Pelvic harness.
  • b. Chest harness.
  • 3. Set up and operate a figure-eight friction
    device.
  • 4. Set up and operate a tandem Prussik brake
    system.

5
OBJECTIVES CONT.
  • 6. Use four methods to attach webbing slings to
    anchors and build two- and three-point
    load-distributing self-protecting anchor systems.
  • 7. Construct three types of picket anchor
    systems.
  • a. Single picket.
  • b. Double picket.
  • c. Combination picket.
  • 8. Set up and operate a simple 21 pulley system
    for application with ladder rescue systems.
  • 9. Set up and operate a simple 31 Z-pulley
    system.

6
BASIC ROPE RESCUE EQUIPMENT
  • 1. Software.
  • a. Rescue rope.
  • b. Webbing.
  • c. Prussik cord.
  • d. Commercial harnesses.
  • 2. Hardware.
  • a. Carabineers.
  • b. Friction devices.
  • c. Pulleys.

7
3. RESCUE ROPE USE
  • a. Raise loads.
  • b. Lower loads.
  • c. Traverse.
  • d. Ensure safety.
  • e. Build pulley systems.

8
ANCHOR SYSTEMS
  • Definitions An anchor (also called anchor
    point) is a stationary object that is heavy
    enough, stable enough, and strong enough to hold
    the load attached to it with rescue rigging.

9
PICKET CAPACITIES
  • Based on average soil
  • a. Single picket 700 pounds.
  • b. 11 1,400 pounds.
  • c. 111 1,800 pounds.
  • d. 321 4,000 pounds.

10
SAFETY LINES
  • Definition A safety line (commonly referred to
    as a belay line) is a backup system to the main
    lowering or raising system which protects rescuer
    and victim in the event of a main line failure.
    Its anchors and components must be as strong or
    stronger than the main line system due to the
    potential for shock loading.

11
RAPPELLING
  • 1. A rappel is a slow, controlled descent down a
    rescue rope using a friction device.
  • 2. Two-line systems are used in training for
    safety.
  • a. A rappel line.
  • b. A safety line.
  • c. Both ½ inch, 9,000 pounds.

12
RESCUE KNOTS
  • 1. Qualities of a good rescue knot.
  • a. Easy to tie.
  • b. Easy to see if tied correctly.
  • c. Will not untie itself.
  • d. Minimal loss in rope strength.
  • e. Relatively easy to untie after being
    loaded.

13
KNOT TERMINOLOGY
  • 1. Knot.
  • A rope that is intertwined.
  • 2. Bend
  • Two rope ends connected together.
  • 3. Hitch
  • A rope around an object.
