chapter 8 basic ropes and systems Flashcards
In rope rescue, refers to nylon webbing, rope and harnesses
software
the three general classifications of rope
utility rope, lifeline, accessory cord
construction method that produces a continuous strand of fiber that runs the entire length of the ropes core
Block creel construction
rope that consist of a protective shield (mantle) over the load bearing core strands (kern)
kernmantle rope
the manufacturers recommended maximum load for a rope or other system componenet
working load
a dynamic and sudden load placed on a rope
impact load
A record of a rope’s working life maintained in accordance with department policy
rope log
simple, open u-shaped fold in a rope
bight
free end of the rope, between the working end and the running end
running part
middle of the rope, between the working end and the running part
standing part
end of the rope used to tie a knot
working end
supplemental overhand knot tied to prevent the primary knot from failing
overhand safety knot
knot used to form a loop in the end of a rope; should be used in place of a bowline knot when working with synthetic fiber rope
figure-eight knot
extra hitch or overhand knot tied in the loose end of a knot to prevent the working end from being pulled through the knot
safety knot
knot that consists of two half hitches; its principal use is to attach a rope to an object such as a pole, post, or hose
clove hitch
method of attaching a piece of software to an anchor; if attached improperly, it can create a weak link in an anchor system
girth hitch
Length of low stretch kernmantle rope, six to eight mm in diameter
prusik cord
a prusik attached onto a main line using a three-wrap prusik hitch to grab the line and prevent it from moving
braking prusik
prusik loop wrapped three times around a line, forming a hitch that can slip along the rope or seize the rope and hold it.
prusik knot
climbers term for a safety line
belay
knot used to form a loop; it is easy to tie and untie, and does not constrict
bowline knot
ancillary equipment used in rope systems
hardware
rescue hardware and equipment that is designed, tested, and labeled for lifting and lowering specific loads
general use
steel or aluminum snap link device for attaching components of rope rescue systems together; 5,000 lb minimum breaking strength
carabiner
friction or mechanical hardware device used to control a descent down a fixed lie or to lower a load
descent device
to descend a rope in a controlled manner using a friction device
rappel
forged metal device in the shape of an eight; used to help control the speed of a person descending a rope
figure-eight plate
device used to create friction for rappelling and as a connection point. This style has extra protrusions to prevent the rope from slipping out of place while the device is in use
rescue eight
a descent device that allows the user to apply or disengage friction bars to change the amount of weight that can be controlled by the device
rappel rack
mechanical contrivance that allows upward but not downward movement when climbing a rope
ascending device
steel or aluminum rollers used to change direction and reduce friction in rope rescue systems
pulley
a single object used to secure a rope rescue system
anchor
total combination or anchor points, slings, and carabiners used to create attachment points for a rope rescue system
anchor system
slang reference to an anchor hat is seemingly immovable
bombproof anchor point
loads that involve motion; includes the forces from falling objects
shock loading
ropes or cables used with lifting or pulling devices such as block and tackle
rigging
method of building a strong anchor system from a weak or inadequate anchor point
tied-back anchor
