List four defects that might be found during rope inspection that would require a rope to be retired.
|
a. cuts
b. excessive fraying c. puffs d. pulled or herniated fibers e. abrasions f. changes in diameter g. discoloration h. glazing of the fibers |
|
|
Before climbing a tree, a climber should inspect the tree for hazards such as
|
a. broken limbs
b. electrical hazards c. dead limbs d. decay e. splits |
|
|
True/False---The load on any piece of climbing or rigging equipment can be many times higher than the weight of the climber or the limb being rigged.
|
true
|
|
|
The ___________ __________ reported by the manufacturer is the breaking strength of a rope or piece of hardware.
|
tensil strength
|
|
|
Climber may also choose to use a _____________-___________ device when tying in. This can reduce the wear on the rope and damage to the tree and can, in some cases, facilitate climbing.
|
friction-saving
|
|
|
A _________-_________ knot is often tied in the tail from the climbing hitch as a ___________ _________ to prevent the end from going through climbing hitch.
|
figure-8, stopper knot
|
|
|
A ___________ is a type of knot used to secure a rope around an object, another rope, or the standing part of the same rope. A __________ joins two rope ends together.
|
hitch, bend
|
|
|
Two methods of using a climbing line to ascend a tree are _________-_________ and _____________ ____________.
|
body-thrust, secured footlock
|
|
|
True/False---When footlocking, putting the hands on or above the Prusik hitch could cause it to slide down the climbing line, creating a fall.
|
true
|
|
|
Because ___________ ___________ can damage a tree, they are approved for use only on trees to be removed, or for aerial rescues.
|
climbing spurs
|
|
|
For added stability and safety, a climber should be secured with a _________-_________ ___________ in addition to the climbing line when using a chain saw in a tree.
|
work-positioning lanyard (or another line)
|
|
|
True/False---The most important factor in any aerial rescue situation is speed--getting the victim to the ground in the shortest amount of time possible.
|
false
|
|
|
____________ is the use of ropes and other equipment to take down trees or remove limbs.
|
rigging
|
|
|
__________-__________ ropes are not recommended for natural-crotch rigging, where the friction of the cover with the tree causes an imbalance in the load taken by the core and cover braids.
|
double-braid
|
|
|
The ___________ __________ of a rope is the tensile strength divided by the working-load limit.
|
design factor
|
|
|
Carabiners must always be loaded along their _________ _________, and never across the gate.
|
major axis
|
|
|
____________ _____________ are heavy-duty pulleys with a large, rotating sheave for the lowering line, and a smaller, fixed sheave to accept a rope sling. In contrast, __________ ___________ are designed for static, overhead rigging, where the loads are known and very low friction is required.
|
arborist blocks, rescue pulleys
|
|
|
True/False---Natural crotches can be fast and effective for use as a rigging point, but the consistent friction and versatility of placement of an arborist block is often a great advantage.
|
true
|
|
|
When the pieces must be removed without dropping either the butt or tip, it can be tied so it is _____________, then lowered to the ground.
|
balanced
|
|
|
A technique in which a piece is tied above the point where it will be cut, and the line is run through a block or crotch below the cut is called __________ __________.
|
butt hitching
|
|
|
The __________ __________ is the classic three-point cut, which dates back to the early years of arboriculture.
|
drop cut
|
|
|
The __________ _________ is a variation of standard tree-felling techniques that employes the use of a notch and back cut to form a hinge and "steer" the limb.
|
topping cut
|
|
|
