RBT(Rigging/Techniques) Flashcards
rigging
the assembly of rope and components used to form anchoring and associated rope systems.
3 principles of rigging
safety
efficiency
effectiveness
when rigging, keep it _____ .
simple
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.
secondary anchors should be _____ the
primary anchor.
directly behind
minimize _____ between the primary and
secondary anchor
slack
For load-sharing anchors the angle
created where the 2 anchor systems come together must be less than _____ .
90 degrees
8 Bombproof Anchors
Steel beams Stairwell support beams Concrete columns BFRs Large trees Motor Vehicles Large machinery Secured eye bolts
directional
any rigging that changes the direction of the rope.
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!
high point anchors are good for 3 things
lowering operations
traverse lines
elevating hauling systems
5 rigging precautions
kiss use edge protection avoid hard links avoid nylon on nylon contact safety check all components before loading
Rappelling
the controlled descent by using the friction
created by the rope passing through a
device.(descender)
“proper rappel”
is a controlled descent with minimal
physical effort.
Never _____ the rate of descent for a
specific height.
exceed
HFD uses 3 devices for descending
carabiner
figure 8 descender(8 plate)
rappel rack
Rate of descent(figure 8 descender) is controlled by which 2 things?
the angle of the rope coming out of the 8
plate.
the amount of rope contacting your body.
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.
Rescuers should be able to rappel utilizing
_____ .
either hand as a brake hand
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.
HFD uses Rappel Racks that are _____
only.
right-handed
When loading a rappel rack, _____ on the line.
keep tension
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

pick-off.
figure 8 on a bight
if rappelling down for a pick-off, the diaper
must be attached to the _____ using a

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

_____ .

u must load them slowly into the diaper

do a line transfer?
an extra descender
an extra carabiner
what additional equipment do you need to
perform a diaper pick-off?
an extra carabiner
the diaper
what additional equipment do you need to

to your system.
safety touch checks
