DESIRABLE KNOT ELEMENTS
Easy to tie Easy to identify Easy to untie Secure under load (not subject to slippage) Tied with few abrupt bends Strong enough for required job
3
ELEMENTS OF A KNOT I Underhand Loop Bight Loop Round Turn Overhand
4
ELEMENTS OF A KNOT II Working End Standing Part Running End
5
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
6
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
7
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
8
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

2 BOWLINE 1 2 3 4
11
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 AROUND OBJECT
4 CLOVE HITCH AROUND OBJECT 1 2 3
14
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
15
5 BECKET BEND 1 2 3
16
BECKET BEND Is not likely to slip when the rope is wet
Is dependable and useful for fire service utility applications
