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

are being hoisted.ii) Examples:(1) Hoisting an axe (along a with clove
hitch).(2) Hoisting a pike pole (along a with

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.

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
