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

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
