Question: Is manila rope a good type of rope for water rescue?

Know Basics on ropes for water rescue and regular rescues.

Question: Cotton Rope: Cotton’s tensile strength is slightly less than that of sisal and considerably less than that of manila.

A       Uses of knots:a)      Bowline:i)        Use- to form a loop that will not

constrict using a natural fiber rope.ii)       Examples:(1)   Hoisting a rope.(2)   Hoisting a smoke ejector.(3) Cannot be used in life safety

situations.

a)      Clove Hitch:i)        Use- to attach a rope to an object and

will stand a pull from either direction.ii)       Examples:(1)   Hoisting an axe (along with half hitches).(2)   Hoisting a pike pole (along with half

hitches).(3)   Hoisting a section of hose (along with half

hitches).

3-7.1. Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1)

a)      Half hitches:i)   Use- to stabilize tall objects that

are being hoisted.ii) Examples:(1)   Hoisting an axe (along a with clove

hitch).(2)   Hoisting a pike pole (along a with

clove hitch).(3)   Hoisting a section of hose (along

with a clove hitch).

3-7.1. Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1)

a)      Double figure of eight:i)        Use- connecting two ropes of equal

diameter together.ii)       Example: to rope off an area.

b)      Figure of eight on a bight:i)  Use- same as the bowline for synthetic

rope and also as an anchoring attachment or harness tie- in.

ii) Figure 8s are tighter and stronger than the bowline.

iii) They are also not as apt to damage the synthetic rope as the bowline will.

iv)  Examples:(1)   Hoisting a ladder.(2)   Hoisting a smoke ejector.

a)      Becket or sheet bend:i)        Use- to attach two ropes of unequal

diameter or a rope and chain together.ii)       Examples:(1)   Tag line.(2)   Attachment of a rope to a chain.b)      Overhand safety:i)        Use- to add a measure of safety to

any knot.ii)       Examples- used with every knot

already mentioned.

Overhand Safety Knot

As an added measure of safety, use an overhand safety knot whenever tying any type of knot.

Question: Use a clove hitch around the head of the axe and at least on half hitch around the handle

A half hitch should be tied through the bale of a charged hoseline, so that it will hold the bale in the closed position as the hoseline is hoisted
