KNOT TERMS

• Working end — Used for forming knot

• Standing part — Between working and running ends

• Running end — Used to hoist, pull, belay, etc.

• Bight — Loop that does not cross over itself

• Loop — Side of bight crossed over or under standing part

• Round turn — End of rope continued around top of loop until standing lengths are parallel

PRIMARY KNOT APPLICATIONS

• Overhand knot A foundation knot for beginning other knots A safety knot or backup to secure other knots (particularly

those of synthetic rope) to prevent the working end from slipping back through the knot and causing it to fail

• Half hitch Hoisting tools Stabilizing tall objects

PRIMARY KNOT APPLICATIONS (cont.)

• Bowline — Various utility and life safety (rope rescue harness) applications

• Clove hitch Attaching ropes to objects Hoisting (with overhand knot)

• Figure-eight — Foundation knot for other knots in family

• Figure-eight follow through — Joining ropes of equal diameters

PRIMARY KNOT APPLICATIONS (cont.)

• Figure-eight on a bight — Securing a loop in middle or end of a rope for a safety line, safety harness, litter and rescue equipment, anchor lines

• Double-loop figure-eight — Constructing a rope rescue harness

• Becket bend (sheet bend) Joining ropes of unequal diameter Joining rope to chain

BOWLINE KNOT

• Is used to form a loop that will not constrict the object it is placed around

• Is untied easily

• Shares degree of acceptability in both life safety and utility applications

CLOVE HITCH

• Is easily formed of two half hitches

• May be used with overhand safety knot for hoisting tools and equipment

• May be formed anywhere on the rope

• Withstands pull in either direction without slipping, when properly tied

BECKET BEND

BECKET BEND

• Is not likely to slip when the rope is wet

• Is dependable and useful for fire service utility applications

FIGURE EIGHT KNOT

• Has replaced the bowline since the introduction of synthetic rope

• Is not as likely as the bowline to damage the rope

• Is stronger than the bowline

• Is an easy knot to tie, untie, inspect, and keep neat

HOISTING A LADDER

HOISTING A LADDER

• Use bowline or figure eight on a bight.

• Place knot through two rungs of ladder about one-third down from top.

• Place loop over top of ladder.
