  1. Knot Tying Terminology • Knot: a weaving or interlacing of rope • Loop: a turn of rope that crosses itself • Round Turn: a 540 degree turn • Turn: an 180 degree turn • Bend: two pieces of ropes or webbing that are connected • Hitch: a loop of rope around an object and pulled against itself

  2. Terminology • Bight: a rope that is bent back and does not cross over itself • Working End: the end used to tie off to an object • Running End: the end that is free • Standing Part: all of the rope that is not attached to the anchor and used for work, such as hoisting or pulling

  3. Turns Ends, Bight, Loop Terminology

  4. Constructing a Knot Three Rules • Dress • Set • Safety

  5. Overhand Knot • A safety or keeper knot to secure loose ends Overhand Knot Loose

  6. Half Hitch • To keep another knot drawn up or to keep the main rope taut

  7. Water Knot / Ring Bend • To attach two pieces of webbing

  8. Clove Hitch • To anchor rope or webbing around bars, poles, and handles • Method 1: • Note: minimum 1 m tag end (running end)

  9. Clove Hitch • Method 2: • Note: minimum 1 m tag end (running end)

  10. Munter Hitch • A two directional friction hitch • Do not load open carabiners.

  11. Three Wrap Prussik • To cinch one rope of smaller diameter to another rope of larger diameter

  12. Figure-Eight Stopper • To stop the running end of the rope from moving through a friction device or rope bag, and to identify the end of the rope quickly

  13. Figure-Eight on a Bight • A secured loop to create an anchor knot

  14. Figure-Eight Bend • To join two ropes together

  15. Figure-Eight Follow Through • Anchor knot used to tie around an object

  16. Double-Loop Figure-Eight • Anchor knot used to create a bigger surface area for load bearing

  17. Running Loop Figure-Eight • To create a loop which can tighten upon itself

  18. In-Line Figure-Eight • To create a loop mid-line in the rope • Note: one directional knot

  19. In-Line Butterfly knot • To create a loop mid-line in the rope • Note: multi-directional knot

  20. Double Fisherman’s Knot • To join two ropes together

  21. Overhand Slip Knot • To safely tie off a rope with the capability of quick release • Note: The aerial stretcher evolution uses a Munter, overhand slip, and overhand keeper

  22. Handcuff Knot • Provide rescuers with the ability to package a patient in order to remove the individual from the dangerous environment • Note: Used as last resort; may cause injury

  23. Hasty Harness To provide rescuers with the ability to package a patient in order to move him or her • Method I: Chalk Line • Method II: Standing

  24. Tie the ends of the webbing together with a water knot. Place webbing on ground around the patient. Step 1 Chalk Line: Method I

  25. Move the webbing at the patient’s head behind the patient’s shoulders and back. Move the webbing at the patient’s feet under the patient’s legs to mid-thigh. Step 2 Chalk Line: Method I

  26. Pull the webbing between the patient’s legs and lay it on the torso. Pull the side sections of the webbing up onto the patient’s torso and over the top of the webbing pulled between the legs. Step 3 Chalk Line: Method I

  27. Lay the chest loops over the leg loops. Step 4 Chalk Line: Method I

  28. Pull the leg loops through the chest loops to form two handholds. Note: The location of the webbing is high on the back and mid-chest. Step 5 Chalk Line: Method I

  29. Tie the ends of webbing together with a water knot. Double up the webbing and drape it over the patient’s shoulder. Reach between the patient’s legs and pull the webbing up to the torso. Step 1 Standing: Method II

  30. Move the leg loops up to the patient’s torso. The rescuer places both arms through the leg loops. The rescuer reaches around the torso and grabs the two loops behind the patient’s back, one in each hand. Step 2 Standing: Method II

  31. Pull the torso loops through the centre of the leg loops to form two handholds. Note: The location of the webbing is high on the back and mid-chest. Step 3 Standing: Method II

  32. Self-Rescue Kit Aluminum Carabiner and Webbing • To provide a firefighter with the knowledge, skill, and equipment to aid the firefighter in rescue situations • Webbing is flat rope

  36. Tool Application Ladders • Large loop, figure eight on a bight • One third from top between the beams • Loop to tip of ladder • Loop over beams • Pull main rope to tighten • Tip away from building

  37. Tool Application Object with Handle • Figure-eight stopper • Running end through handle • Trace figure eight, figure-eight follow through • Safety knot

  38. Tool Application Pike Pole • Clove hitch on handle • Two half hitches toward tip • Tip up

  39. Tool Application Axe / Sledge Hammer • Figure eight on a bight • Safety knot • Loop over handle • Bend rope over axe head • Two half hitches on handle
