Q

Kernmantle Rope

A

Is a jacketed synthetic rope composed of a braided covering or sheath (mantle) over a core (kern) of the main load-bearing strands

The core is made of high-strength fibers, usually nylon, which accounts for 75 percent of the total strength of the rope

The sheath provides the rest of the ropes overall strength and protects the core from abrasions and contamination

Q

Static rope

A

(low-stretch)

Used for most rope rescue operations

It is designed for low stretch without breaking

Low-stretch rope must not elongate more than 10 percent when tested under a load equal to 10 percent of its breaking strength

Used for rescue, rappelling, and hoisting and where falls are not likely to occur or only very short falls are possible

25
when inspecting kernmantle rope
put a slight tension on the rope while feeling for lumps, depression or soft spots Soft sports are caused by knots or bends, but they may not be signs of permanent damage to the core because core fibers may only be temporarily misaligned
26
when inspecting laid rope
Synthetic rope should be untwisted so that all sides of each strand can be inspected
27
Braid-on-braid rope inspection
Feel for lumps, which indicates core damage If the ropes diameter has shrunk, this may indicate a break in the core
28
Maintaining Rope
- Avoid abrasion and unnecessary wear - Avoid sharp angles, bends and knots - Protect ends from damage - Avoid sustained loads - Avoid rust - Prevent contact with chemicals - Reverse ends of the rope periodically - Do not walk on rope
29
Cleaning synthetic fiber rope
To loosen imbedded dirt particles, wash synthetic fiber ropes with a mild detergent or fabric softener added in lukewarm to warm water
30
Cleaning synthetic fiber rope - 3 methods
Wash by hand Rope-washing device Washing machine
31
Cleaning synthetic fiber rope - After you have washed and rinsed the rope you must dry the rope immediately
Never place it near a heat source or use a heated dryer because heat can reduce the ropes tensile strength
32
cleaning natural fiber ropes
Wipe or gently brush the rope to remove as much or the dirt and grit as possible Do not use water, as this will damage the rope
33
Maintaining a Rope Log
Keep a rope log for every life safety rope throughout the ropes working life
34
rope log must include
Product label, identification label and manufacturers instructions Information regarding purchase date, use, maintenance and inspection Incidents that result in impact loading
35
Rope Storage
Should be stored in a clean, dry, unheated area with freely circulating air currents
36
what kind of bag to store rope
Best method for storing rope is to place it into a nylon or canvas storage bag The bag makes the rope easy to transport and protects it from abrasion and contamination
37
Webbing - Material and Construction
Webbing is constructed from the same materials used to make synthetic rope
38
flat webbing
Is constructed of a single layer of material that resembles an automobile seat belt It is stiffer and more difficult to tie into knots Mainly used for straps and harnesses
39
tubular webbing
Commonly used for rescue applications Easier to tie than flat webbing
40
two types of tubular webbing
edge-stitched spiral weave
41
edge-stitched tubular webbing
formed by folding a piece of flat webbing lengthwise and sewing the edges together
42
spiral weave tubular webbing
preferred for rescue work
43
knots - Rope is divided into three parts
working end running part standing part
44
working end
used to tie the knot or hitch
45
Running part
free end that is used for hoisting or pulling
46
standing part
section between the working end and running part
47
dressing the knot
after tying all slack should be removed
48
49
overhand safety knot
One way to prevent failures is to tie a overhand safety knot in the tail of the working end
50
To be suitable for use in the fire service, a knot must:
Be easy to tie and untie Be secure under load Reduce ropes strength as little as possible
51
Overhand safety knots
As an added measure of safety, an overhand safety knot can be used when tying any type of knot
52
Clove Hitch
Principally used to attach a rope to an object such as a pole, post or hose line
53
Figure-eight
It can be used as a stopper knot so that the rope will not pass through a rescue pulley or the grommet of a rope bag
54
figure-eight bend
Primarily used on life safety rope to tie ropes of equal diameter together
55
figure-eight on a bite
Good way to tie a closed loop
56
figure-eight follow through
Used for securing objects
57
water knot
Preferred knot for joining two pieces of webbing or the ends of the same piece when a loop is needed
58
Rope and webbing are frequently used to raise or lower tools and equipment, with one notable exception
Prohibits hoisting pressurized cylinders
59
Tag line
A separate tag line may be tied to the equipment or part of the hoisting line may also serve as a tag line Are non-load-bearing and help prevent tools from spinning or snagging while being hoisted Firefighters on the ground use the tag line to prevent the equipment from striking the structure or other objects
60
Carabiner
Is a snap link made from aluminum, titanium or steel with a spring or screw gate that connects ropes to other mechanical gear
61
Pulley
Simple device used to create a mechanical advantage or change in direction Consist of a grooved wheel which a rope can run to change the direction or point of application of a force applied to the rope
62
Personnel should never use utility rope during rescue operations, instead use life safety rope for:
Rappelling Lifting victims and rescuers Removing victims from ice and swift weather situations
63
Control Zone Perimeter
Utility rope has traditionally been used to establish the perimeter to control access to required control zones Clove hitch with overhand safety knots are used to tie the rope to trees, sign posts or other stationary objects
64
Search lines
Used to assist search teams working in dark, smoke-filled or confined spaces They allow team members to remain in contact with each other and with firefighters at the lines entry point They also provide a physical means of finding an exit route
65
Object stabilization
Utility rope and webbing are sometimes used to stabilize an object
66
Before any work is performed around the object, you must be certain that:
The rope or webbing and the anchor point are strong enough to hole the weight of the object The knots are tight and safety knots are in place The attachment points at both ends are secure and will not pull free Personnel are clear from the stabilizing line in case it breaks and snaps back
