Ropes:

Ropes


    A length of thick strong cord made by twisting together strands of Hemp, Sisal, Nylon, or similar material.
    A rope is the one essential element in the high-angle system.
            -It is in essence a tool.
            -As with all tools, the correct rope should be chosen to fit the job.
The rope is a tool that is used in emergency situations to save human lives.
A rope is a multipurpose tool used from ancient times. Ropes are essentially required to lower, lift, and pull a victim or any load in any emergency situation.

Parts Of a Rope (According to use):

1. Working End: 

            Part of the rope which is tied with the anchor point is called the working end.

2. Running End:

            Part of the rope is used for work such as hosting.

3. Standing Part:

            Part of the rope between the working end and the running end.

Rope Construction:

            The choice of a rope for a specific job depends not only on the fiber from which the rope is made but also on how the rope is constructed.

        1. Laid

        2. Plated

        3. Braided

        4. Kernmantle

1. Laid:



     -   Also known as twisted or hawser lay
     -   Small fiber bundles of material are twisted and then combined in larger bundles, usually in groups of three, which are twisted around one another in the opposite direction.

2. Plaited:



        - Usually consists of bundles of fiber plaited together.
        - Tend to be soft and pliable.
        - Prone to picking 

3. Braided:



     > Hollow-braid rope

        - Essentially a very thick sheath.
        - Sometimes has a filler, such as a scrap yarn or filament plastic.
        - Typically found in inexpensive hardware store-type rope, not in life safety line.
    > Essentially a rope constructed of a solid braid covered with a hollow braid.
    > One braid acts as the rope core.
    > The second braid is constructed around it too :
        - Act as a sheath
        - Help protect the inner braid

4. Kernmantle



        - kern means "Core"
        - Mantle means "sheath" or "cover"

2. Types of Rope:

2.1. Utility Rope

2.2. Life Safety Rope

2.1. Utility Rope

        This rope is made of natural fibers and cannot be used in life-saving activities. It is used to secure the equipment. it is made by connecting several fibers. Its strength is in doubt, Water and other chemicals may damage this type of rope.

2.2.1 Life Safety Rope:

        Rope intended to support people during a rescue, fire fighting, other emergency operation, or during training.

        Life safety rope is divided into two types.

        2.2.1. Static Rope

        2.2.2. Dynamic Rope

2.2.1. Static Rope (Low-stretch)

        A type of rope designed to be used in applications such as rescue, rappelling, and ascending which high or moderate stretch would be a disadvantage in which no falls, or only shortfalls, are expected before the climbers are caught by the rope.
        A static rope is one designed with low elongation characteristics these ropes normally elongate around 2% to 3% under one person's body weight, and not more than 20% at the ultimate breaking point,

2.2.2. Dynamic Rope (high-stretch)




        A type of rope designed to high stretch to reduce the shock on the climber and anchor system. This type of rope usually is used in rock climbing and mountaineering. It is also called high-stretch rope.

3. Care and maintenance of Ropes:

        A rope's performance, how long it lasts and its safety still depends on how well it is carried. The condition of a rope ultimately depends on its history.

3.1. Care of rope BEFORE USE:

        - Remove the kinks in the rope.
        - Secure the end of the rope with a stopper.
        - Inspect the rope thoroughly.
        - Do not use it if there is any damage.

3.2. Care of Rope DURING USE:

        - Do not drag on the ground.
        - Do not use it in wet places.
        - Do not pass over the sharp edges.
        - Avoid contact with heat, grease, oil, and chemicals.
        - Avoid walking or standing on the rope.

3.3. Care of Rope AFTER USE:

         - Inspect the rope thoroughly. If there is damage tie a knot there. Report immediately to the concerned person and do not use it again.
        - Secure/Fold/Coil the rope after removing kinks.
        - Do not leave knots in a rope as they can reduce its strength.
        - Do not dry ropes in front of the fire or other heat sources.

Knot:          An intertwined loop of rope is used to fasten two ropes to each other. Hitch:          A hitch is a knot that attaches a rope to any object. Bight:          Any curved section between the ends of the rope. Loop:          A bight becomes a loop when the ends of the rope are crossed. Bend:          A class of knots that joins two ropes or webbing pieces. 10 Most Important Basic Rescue Knots: 1. Stopper Knot          This knot is applied on the ends of the rope to rescue the fibers of the ropes. It is also used after every knot to secure the knot. Stopper 2. Clove Hitch          The clove hitch is used to fasten the rope on the anchor point. It is the advantage of being easy to tie and adjust. when it is under load it will have a tighter grip on the anchor point Clove Hitch 3. Reef Knot    ...
