ROPES & KNOTS

DEFINITIONS

Remember these definitions to better understand and remember the knots used:

Knot - when a strand of material is tied to itself (knot is a general term for all knots, bends, and hitches. The definition given is a more descriptive term.)

Bend - when two or more strands of material are tied to each other.

Hitch - when a strand or strands of material is tied around another object in such a manner that if that object were removed, the hitch would undo itself.

Running end - the end of the rope that is being worked with.

Standing end - the bulk of rope not being actively used.

Bight - a 180° turn in a strand of rope. Loop - a 360° turn in a strand of rope.

KNOT DEFINITIONS

BACK-UP KNOT: A knot used to back-up the main load-bearing knot. Back-up knots should be nestled against the main knot to limit shock-load. Typically, a double overhand is used as a back-up. BOWLINE KNOT: A knot used throughout the fire service. The advantage of this knot is that it is easy to untie after being loaded, which is why a back-up knot is required. The Yosemite finish is preferred. The variations that will be used in this class consist of long tail, interwoven and the interlocking long tail. DOUBLE OVERHAND BEND: Also known as a double fisherman's knot. Used to join two ends of rope together, commonly used for joining the ends of Prusik loops.

DOUBLE OVERHAND KNOT: Preferred back-up knot.

DIRECTIONAL EIGHT OR IN-LINE EIGHT: This knot is used for re-directing a rope. Used for tensioning or securing a system. The directional knot enables the rope to stay inline while securing the load. FIGURE EIGHT FOLLOW THROUGH: Used extensively in rope rescue. This knot is used to tie around an object.

FIGURE EIGHT ON A BIGHT: Used to tie a loop in the end of a rope. FIGURE EIGHT: Used as a stopper knot in the end of a rope. Also to begin a figure eight follow through. OVERHAND FOLLOW THROUGH: Knot typically used for webbing. Also known as ring bend or water knot. A tail of one hand width is required after the knot is tied. REMEMBER: A rule of thumb important to remember is that knots weaken rope approximately 1/3. So our 9000# rope just became 6000# with a knot in it. Do you need the knot? Can the knot be placed in the system where there is no strain on it? A knot isn't properly tied unless it is "stressed and dressed." Ropes and webbing are pieces of equipment that deteriorate over time. Take care of them and replace as per the WAC. This includes personal gear.
