How is the Rope measured to get 1 and a 1/2 arm lengths?

Measurement of rope required to form the various knots and hitches is made by stretching the

hand.

Q

The bowline on a bight is used in conjunction with what 2 hitches?

A

The bowline on a bight is a very important knot. It is commonly used to lower a firefighter to rescue persons trapped at windows which are not readily accessible to ladders. Other rescue purposes include the lifting of persons from excavations, sewers, etc., and the lowering of persons from places where safer escape routes are not available. The bight forms a cradle to support the firefighter and the bowline prevents the rope from tightening or slipping. The bowline on a bight is used in conjunction with a half hitch and a slippery hitch tied about the chest.

Q

When do we use a rolling hitch?

A

The rolling hitch is used to secure a hose line which has been hoisted via the outside of a building. It is tied directly beneath the couplings just below the edge of the roof or window. The free end of the rope is taken back on roof and secured to some substantial object. The rolling hitch relieves the couplings of the weight of the hose.
