Chapter 8 Flashcards
What rope is designed exclusively for rescue and other emergency operations?
life safety rope
What is life safety rope used for?
to raise, lower, and support people at an incident or during training
What is NFPA 1983?
NFPA 1983, Standard on Life Safety Rope and Equipment for Emergency Services
What rope is designed for any use except rescue?
utility rope
What is utility rope used for?
to hoist equipment, secure unstable objects, or cordon off an area
What is a single use rope intended for emergency self-rescue situations? This rope is designed to carry the weight of only one person and must be destroyed after its use
escape rope
What is a method of manufacturing rope without any knots or splices? A continuous strand of fiber runs the entire length of the rope’s core
block creel construction
What is a dynamic, sudden load placed on a rope? (typically during a fall)
impact load
What must be kept for every life safety rope?
rope log
What rope loses its strength when it gets wet and rots rapidly?
natural fiber rope
What rope is made from continuous, synthetic fibers running the entire length of the rope?
synthetic fiber rope
What are synthetic fiber ropes resistant to?
water, mildew, mold, rotting, shrinkage, and UV light
What are advantages of synthetic fiber rope?
longer life span than natural fiber rope, strong yet lightweight, easy to maintain
What are disadvantages of synthetic fiber rope?
they will melt when exposed to heat
What is a utility rope made of manila, sisal, or cotton? (not accepted for life safety applications)
natural fiber rope
What are advantages of natural fiber rope?
resistant to sunlight, does not melt when exposed to heat, and holds a knot firmly
What are disadvantages of natural fiber rope?
prone to mildew and mold; deteriorates when exposed to chemicals and burns when in contact with ember or flames
What are the most common type of rope construction?
kernmantle, laid, braided, and braid-on-braid
What rope is the only one used for life safety?
kernmantle
What rope consists of a protective shield (mantle) over the load-bearing core strands (kern)?
kernmantle rope
What rope is designed to stretch under load, reducing the shock of impact after a fall?
dynamic rope
What rope is designed not to stretch under load?
static rope
What are the two types of kernmantle rope?
dynamic (high-stretch) and static (low-stretch)
What rope is constructed by twisting several groups of individual strands together?
laid rope
What is a disadvantage of laid rope?
susceptible to abrasion and other physical damage
What rope is constructed by uniformly intertwining strands of rope together?
braided rope
What rope consists of a braided core enclosed in a braided herringbone patterned sheath?
braid-on-braid rope
Why is braid-on-braid rope sometimes confused with kern mantle?
bc both are jacketed
What is a disadvantage of braid-on-braid rope?
doesn’t resist abrasion as well as kernmantle; sheath may slide along the inner core of the rope
How do you inspect laid rope?
by untwisting it so that all sides of each strand can be inspectd
What is a device used for creating anchors and lashings or for packaging patients and rescuers? This is typically constructed from the same material as synthetic rope
webbing
What are the two types of webbing?
flat and tubular
What is the most common webbing for rescue applications?
tubular webbing
What is a belt with a hook that secures FF to the ladder?
ladder belt
What webbing/rope is regulated by a standard? (NFPA 1983)
life safety
What is a term used for tying a rope around itself?
knot
What is the end of the rope used to tie a knot? also known as bitter end or loose end
working end
What is the free end of the rope used for hoisting, pulling, or belaying?
running part
What is the middle of the rope between the working end and running end?
standing part
What is a supplemental knot tied to prevent the primary knot from falling? This prevents the running end of the rope from slipping back through the primary knot
overhand safety knot
What is a temporary knot that falls apart if the object held by the rope is removed? This loop secures the rope but is not part of a standard rope knot
hitch
What are the names for the bends that a rope undergoes when tying a knot or hitch?
bight, loop, or round turn
What knot is used to form a loop? It is easy to tie and untie and does not constrict.
bowline knot
What knot is typically used to stabilize long objects that are being hoisted? This is always used in conjunction with another knot
half-hitch
What knot consists of two half-hitches? Its principals is to attach a rope to an object such as a pole, post, or hose
clove hitch
What knot is tied in a bight with two adjustable loops in opposing directions? This is used during rescue to secure hands and feet so that the victim can be dragged out
handcuff knot
What figure eight knot is used primarily on life safety rope to tie ropes of equal diameter together?
figure eight bend
What figure eight knot is a good way to tie a closed loop?
figure eight on a bight
What figure eight knot is used for securing objects?
figure eight follow through
What knot is used for joining two ropes? Particularly suited for joining ropes of unequal diameter or joining a rope and a chain
becket bend
What is the preferred knot for joining two pieces of webbing?
water knot
How much webbing should be left for the tail of a water knot?
at least 3”
What is a non-load bearing rope attached to a hoisted object to help steer it in a desired direction preventing it from spinning or snagging on obstructions? Can also act as a safety line
tag line
What is an advantage created when levers pulleys and tools are used to make work easier during rope rescue or while lifting heavy objects?
mechanical advantage
What rope and knot is used when controlling zone perimeter? This knot is used to tie the rope to trees, sign posts, or other stationary objects
utility rope; clove hitch with a half-hitch overhand safety knot
What is used to help search teams working in dark, smoke-filled or confined spaces? This allows team members to remain in contact with each other and with FF at the line’s entry point.
search lines
