5 anchoring principles

use a bombproof one if possible such as a
BFR.
use edge protection for rope.
if in doubt, use a secondary anchor or
create a load-sharing anchor.
test the anchor’s sturdiness prior to using.
visually inspect the anchor prior to using.

extending an anchor

creating another place to attach rope that
is in a better location the original anchor
point. normally done by extending/lowering a rope with a pulley attached…which allows the rope system to pass through the pulley
at that location. good for creating high points!

Rate of descent(figure 8 descender) is controlled by which 2 things?

plate.

3 ways to increase the amount of rope
contacting your body and increasing
friction.

wrap tighter with brake hand.
pull rope into body with brake hand.
wrap rope around body towards the
small of your back.

Locking off the Figure 8
what does the guide hand do?
what does the brake hand do?
what do both hands do?

grips base of 8 plate and top of carabiner
and angles 8 plate towards the incoming
brake hand.
brings the rope up and behind the 8 plate
and between the rope and around the
ears (2x).
form a bight and bring it through the
opening of the 8 plate and wrap it
around the ears. then cinch tight. or…
form a bight and tie an overhand knot around the standing(loaded) line.

when loading a rappel rack,
use right hand to _____ .
use left hand to _____ .

grip/control rope (bring lines together).

position bars.

Controlling the rate of descent (rack)
the left hand _____ .
the right hand _____.

with palm up, use thumb and fingers to 
grip bars from below and move then 
up(slower) or down(faster).
holds the rope, move upward to slow
move down to go faster.

Locking off the Rappel rack(no tie off bar). the left hand _____ . the right hand _____ .

slides bars together tight and holds them. moves rope upward and around standing line forcefully. then secures around the bottom of the short leg with a half-hitch.

Locking off Rappel Rack with tie-off bar

same as other rack except you make a complete wrap around the bars and then tie a half-hitch around the tie-off bar.

when rappelling, 2 types of safety belays | may be used.

bottom belay | safety line belay(Munter Hitch + XL carabiner)

can safety belays used simultaneously?

yes

2 safety belay precautions

be alert and ready by watching the rappeler at all times. have just enough slack so as not to impede the rappeller and you are able to apply tension quickly enough to stop the rappeller.

bottom belay has two methods to stop | rappeller

bring hands together. | roll body to the side of the rear foot.

4 keys to the correct stance for bottom belay

stand within 45 degrees of the top of rappel. rope is under armpits feet shoulder-width apart one foot behind the other so that you are standing sideways but facing the rappeller.

proper position for the safety belay person

between the 2 ends of the rope facing | anchor with the carabiner/munter hitch.

4 safety command initiated prior to rappel

on rappel on belay on safety good to go

what do both the bottom belay man and the rappeller do when shouting their safety commands?

tap the top of their heads.

the basic body position for rappelling is an | _____ .

L shape.

upper body is _____ while rappelling.

parallel to the wall/cliff

legs are _____ while rappelling.

perpendicular to the wall/cliff.

safety touch checks are _____ .

mandatory. performed by the rappeller. performed by the rappel master.

for self-rescue you attach a _____ to the rope above the ______ . then if necessary, you add another one to extend it. Then you step into it and stand up using it to hold your weight. use your hands _____ and _____.

pruski loop descender. to grab the rope clear yourself as needed.

to perform a line transfer you will need to have at least one extra _____ and one extra _____ .

carabiner | descender

10 line transfer steps

rappel down to desired location. lock off. gather second line. rig second line to your harness taking out all the slack. lock off second line. transfer as much load as possible to second line. conduct a safety touch check. unlock and slowly unload from first line to second line. stow 1st line hardware. unlock 2nd line and continue rappel.

When should u double wrap a figure 8 | descender?

any time you will be supporting a 2 person | load.

Rescue 2 attaches a 2nd carabiner to the _____ when being belayed for a diaper pick-off.

figure 8 on a bight

if rappelling down for a pick-off, the diaper must be attached to the _____ using a separate carabiner.

rappeller's carabiner.

if rappelling down for a pick-off, the pick-off strap is attached to the ______ or the ______ using a separate carabiner.

smaller ring of the 8-plate. | eye of the rappel rack.

if you will be using a diaper, level off _____ .

even with the victim.

if you will be using a pick-off strap, level | off _____ .

above the victim so that you can pull them up tight to you using the pick-off strap. (this should unload the victim's line)

When diapering, the orange reflective stripe | _____ and the 3rd D-ring goes _____ .

goes around the victim's upper torso. | between the victim's legs from behind.

remember to unlock and slowly unload a victim from their own line when doing _____ .

diaper pick-offs | u must load them slowly into the diaper

Which end of the pick-off strap will be | attached to the victim?
