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
