CHAPTER 8 - ROPES, WEBBING, AND KNOTS Flashcards
Rope designed for any use except rescue; can be used to hoist equipment, secure unstable objects, or cordon off an area
Utility rope
Rope designed exclusively for rescue and other emergency operations.
Life safety rope
Method of manufacturing rope without any knots or splices; a continuous strand fiber runs the entire length of the rope core
Block creel construction
Dynamic and sudden load placed on a rope, typically during a fall.
Impact load
Rope made from continuous, synthetic fibers running the entire length of the rope; it is strong, easy to maintain, and resists mildew and rotting.
Synthetic fiber rope
Utility rope made of Manila, Sisal, or cotton; not excepted for life safety applications.
Natural fiber rope
Rope that consists of a protective shield over the loadbearing core strands
Kernmantle rope
Rope designed to stretch under load, reducing the shock of impact after a fall.
Dynamic rope
Rope designed not to stretch underload
Static rope
Rope constructed by twisting several groups of individual strands together
Laid rope
Rope constructed by uniformly intertwining strands of rope together
Braided rope
Record of all use, maintenance, and inspection throughout a ropes working life; also includes the product label and manufacturers recommendations
Rope log
Device used for creating anchors and lashings, or for packaging patients and rescuers; typically constructed from the same material as synthetic rope
Webbing
Belt with a hook that secures the firefighters to the ladder
Ladder belt
Term used for tying a rope around itself
Knot
End of the rope used to tie a knot also known as bitter end or loose end
Working end
Free end of the rope used for hoisting, polling, or belaying
Running part
Middle of the rope, between working and running part
Standing part
Temporary not that falls apart if the object held by the rope is removed. Loop that secures the rope but is not part of the standard rope knot
Hitch
Supplemental knot tied to prevent the primary knot from failing; Prevents the running end of the rope from slipping back through the primary knot
Overhand safety knot
Knot used to form a loop; it is easy to tie and untie; does not constrict
Bowline knot
Knot typically used to stabilize long objects that are being hoisted; always used in conjunction with another knot
Halfhitch
Knot that consists of two half-inch is; it’s principal use is to attach a rope to an object such as a pole, post, or hose.
Clove hitch
Knot tied on a bite with two adjustable loops and opposing directions; used during rescues to secure hands or feet, so that a victim can be raised or dragons to safety
Handcuff knot
Knot used for joining two ropes, particularly well-suited for joining two ropes of unequal diameters were joining a rope and a chain
Becket bend
Non-loadbearing rope attached to a hoisted object to help steer it in a desired direction, prevent it from spinning or snagging on obstructions, or act as a safety line
Tagline
Advantage created one levers, pulleys, and tools are used to make work easier during rope rescue or while lifting heavy objects
Mechanical advantage
NFPA 1973 lists life safety rope regulations. True or false?
False – NFPA 1983
There is no NFPA standard that lists requirements for utility rope. True or false?
True
NFPA 1983 requires that all types of ropes have a rope log. True or false?
False – only life safety ropes require a log
Natural rope is resistant to water, mildew, mold, and writing. True or false?
False – it is prone to mildew, mold, and rot
Synthetic fiber rope is very strong yet lightweight. True or false?
True
Some fuzziness in a kernmantle construction rope is normal. True or false?
True
Natural fiber and synthetic fiber ropes are washed in the same way. True or false?
False – natural fiber ropes cannot use water
A rope log is usually stored in a pocket sewn into the side of the rope storage bag. True or false?
Who
Webbing used for life safety must be NFPA compliant. True or false?
True
Both life safety and utility webbing are regulated by NFPA standards. True or false?
False – life safety only
The load carrying ability of a rope must exceed the weight of the object hoisted or stabilized. True or false?
True
This rope is constructed of a braided sheath over a core of mainn loadbearing strands
Kernmantle
This rope is constructed by uniformly intertwining strands together in a diagonally overlapping pattern
Braided rope
This rope is constructed by twisting fibers together to form strands, then twisting the strands together to make the final rope
Lead rope
This rope is constructed of a braided core enclosed in a braided, herringbone patterned sheath
Braid on braid
This webbing fastens around the waist, under the size or by text and over the shoulders; it is rated for loads up to 600lbs
Class III life safety webbing
This webbing fastens around the waist and under the thighs or buttocks and is rather for a load up to 600lbs
Class II fire safety webbing
This webbing is used for a variety of uses and is not regulated by any specific standard.
Utility webbing
This webbing is known as a seat harness and is intended for emergency escape with a load of up to 300lbs
Class I life safety webbing
This aspect of the knot is the section between the working end and the running part.
Standing part
This aspect of the knot is formed by bending the rope back on itself while keeping the sides parallel
Bight
This aspect of the knot is made by further bending one side of the loop
Round turn
This aspect of the knot is the free end used for hoisting or pulling
Running part
This aspect of a knot is made by crossing the side of the night over the standing part.
Working end
A life safety rope should be removed from service or replaced if:
It has been subjected to any impact load.
According to NFPA 1983 a rope log must include:
Purchase date
