minimum breaking strength of 3,000 pounds

|
|
Term
|
Definition
jacketed rope; composed of a braided sheath over a core (kern) of the main load-bearing strands
core strands run parallel with the rope's length and work in conjunction with the covering
core is usually nylon, making up for 75% of the rope's total strength
comes in both high-stretch and low-stretch |
|
|
Term
|
Definition
typical of most natural fiber and some synthetic
three strands are twisted around to make the final rope
susceptible to abrasion and physical damage
exclusively utility ropes |
|
|
Term
|
Definition
most are synthetic
uniformly twisting strands, similar to braiding hair
subject to direct abrasion and damage
most commonly used as utility rope |
|
|
Term
|
Definition
often confused with kernmantle rope
both a braided core and a braided sheath
herring-bone pattern appearance
very strong, but does not resist abrasion as well as kermantle, and the sheath may slide along inner core
most often utility rope |
|
|
Term
|
Definition
all types after each use
unused rope annually |
|
|
Term
| Inspecting kernmantle rope |
|
Definition
slight tension on rope; feel for any lumps, depressions or soft spots
look for irregularities in shape or weave, foul smells, discoloration, roughness, abrasions or fuzziness |
|
|
Term
|
Definition
inspect for soft, crusty, stiff or brittle spots
look for excessive stretching
can be untwisted and checked internally |
|
|
Term
|
Definition
look for exterior damage such as heat sears, nicks, and cuts
look for excess or unusually fuzziness |
|
|
Term
| Inspecting braid-on-braid rope |
|
Definition
look for heat sears, nicks and cuts
look for sheath sliding on the core; if found, cut the end of the rope and pull off the excess material, then seal the end
inspect for lumps and reduction in diameter that indicate core damage |
|
|
Term
| Cleaning natural fiber rope |
|
Definition
Cannot be cleaned effectively because water damages the rope
wipe or gently brush to remove as much dirt and grit as possible |
|
|
Term
| Cleaning synthetic fiber rope |
|
Definition
cool water and mild soap; do not use bleaches or strong cleaners
Can be dried on a rack OUT OF DIRECT SUNLIGHT |

Term
|
Definition
| part of the rope used for work such as hoisting, pulling or belaying |

|
Term
|
Definition
part of the rope that is to be used in forming the knot
also called Bitter End or Loose End |
|
|
Term
|
Definition
| part of the rope between the working end and running end |
|
|
Term
|
Definition
| knot tied at the working end of the rope to prevent slipping |
|
|
Term
|
Definition
one of the most important knots used in fire service
easily tied and untied, good for forming a single loop that will not constrict the object it is placed around
used on natural fiber rope |
|
|
Term
|
Definition
useful in stabilizing long objects that are being hoisted
always used in conjunction with another knot
half-turn around the object |
|
|
Term
|
Definition
consists of two half-hitches
not regarded as suitable for anchoring a life-safety rope
principal use to attach a rope to an object such as a pole, post or hose |
|
|
Term
|
Definition
foundation knot, used as a stopper so that the rope will not pass through the rope bag or rescue pulley
used in place of a bowline knot when working with synthetic rope |
|
|
Term
|
Definition
'Flemish bend'
used primarily on life-safety rope to tie ropes of equal diameters together |
|
|
Term
|
Definition
good way to tie a closed loop at the end of a rope
bight on either end of the rope, and then tying a simple figure eight with the bight in the doubled part of the rope |
|
|
Term
| Figure-eight follow-through |
|
Definition
secures a rope around an object
starts off with a single figure eight, the end is wrapped around an object and follows back through the single figure eight
outcome is a figure eight on a bight that is around an object |
|
|
Term
|
Definition
used for joining two ropes of unequal diameters or joining a rope and chain
unlikely to slip when wet
useable and dependable, but not suitable in life-safety applications |
|
|
Term
|
Definition
preferred knot for joining two pieces of webbing or the ends of the same piece when a loop is needed
tie a simple overhand knot in one piece or end, and follow it through in the reverse direction with another piece or end |

Definition
easier and safer to hoist dry hoseline, but charged can be hoisted too
do not damage coupling or the nozzle |
