How To... Tie the Two Basic Firefighter knots

Today we are talking about the two most basic knots taught to those learning to become Bush Firefighters in the NSW Rural Fire Service. These are the Clove Hitch and the Round Turn and Two Half Hitches.

Both of these knots have practical uses elsewhere, such as in sailing or in everyday maintenance around the home (i.e. in the Garden). Both knots are generally used around a round object, such as a pole, or a tree branch, among others.

If the instructions sound confusing, don't worry, they become clear when you put them together with the illustrations.

The Knots:

1. The Clove Hitch

a) This knot consists of two half hitches with the second reversed

b) Procedure:

    i. Pass the end of your rope over the object leaving enough length on the end for another pass.

    ii. For the second pass, make sure to cross the rope over the first length, then bring the end up through the gap between the two lengths of rope, creating your knot. 

    iii. Pull the rope tight to strengthen the knot.


This knot does have its failings. If the tension on the rope is not consistant and the rope is not kept straight, the knot may slip and come undone.

2. The Round Turn and Two Half Hitches
a) This knot consists of a round turn around the object, and then two half hitches around the original length of rope

b)Procedure:
    i. Pass the rope around the object, then do so a second time

    ii. Then, instead of making another pass over the object, this time pass it over your original length of rope, threading the end through the gap created, thus creating your first Half Hitch

    iii. Repeat the second process by passing the rope over the original length a second time

    iv. Pull the rope tight, and you have created your knot


This knot is better than the Clove Hitch, in that it can withstand any tension without jamming or coming undone, and can be easily undone when the tension is lifted.

The Clove Hitch is generally used for jobs that do not require alot of effort, for example it is used to lift wet hoses up the pole so that they can dry.

The Round Turn and Two Half Hitches is used for harder jobs that require more effort, such as lifting or lowering equipment or shifting large branches off the road.
