Carabiners
- Rope on rope or rope on webbing should be avoided as it can overheat from friction
and cause rope damage
Natural Anchors - Answer-- Most commonly trees and boulders
- Their strength is estimated based on their size and the condition of the surrounding
soil and slope
- Whenever possible, anchor webbing should be placed as close to the base (bottom)
as practical
Vehicles can be used as anchors provided that.... - Answer-- The engine is shut off
- Keys are removed
- Brake is set
- Wheels are chocked
- A person is assigned to make sure that the vehicle is not started or driven

structural member of the chasis
If you are attaching an anchor to a wheel, how should you do it, and what do you need
to be aware of? - Answer-- Through the wheel rim
- Be aware of hot brakes when anchoring to a rim
90 Degree Rule - Answer-It is important that any strap or webbing used to create an
anchor should not be wrapped so tight around an object as to create an interior angle
greater than 90*
- This rule also applies to multiple point anchors and high line system
Why is it important to keep the interior angle less than 90*? - Answer-As the angle
increases, the load on the anchors multiplies dramatically
What is a "full strength tie-off" also known as? - Answer-Tensionless anchor
How is a full strength tie-off constructed? - Answer-By using only the rope itself around
an object, eliminating the need for an anchor strap. The rope is wrapped around the
anchor a minimum of 2 times and then attached back on itself utilizing a figure 8 on a
bight and a carabiner
, What knot is used during lowering operations? - Answer-Munter hitch
What is a downfall of the Munter Hitch? - Answer-The twists that it can put in a rope on
a longer descent
T/F: When raising loads, a simple 1:1 straight pull is usually sufficient. - why? - Answer-
True - Due to manpower availability
What is usually the smoothest and most efficient way of pulling? - Answer-Grasping the
rope and walking away
What pieces of equipment are still necessary for a straight pull 1:1? - Answer-Prusik
and Prusik minding pulley
- Will allow the pull to be in the most convenient direction and the prusik will grip and
hold the load in the case of slippage or if the haul team needs to take another purchase
What 2 things can be done if the haul team as difficulty raising the load? - Answer-- Call
for more personnel
- 3:1 pulley system can be implemented
After a line has been anchored at both ends, how is a tensioning system created? -
Answer-The line is run through a prusik minding pulley with a prusik. Two haulers pull
tension on the line and one person engages the prusik.
Steps for creating a 3:1 system: (5) - Answer-1. Begin with the standard raising
operation set up
2. Find another anchor - a webbing basket sling anchor will be needed
3. If another pulley is not available, pass the rope over the carabiner at the second
anchor
4. Place a prusik back on the line heading toward the 1st pulley
5. Finish by placing a carabiner on the prusik and running the rope through the
carabiner
Define "Low Angle" - Answer-Low angle is defined as any sloped surface that a FF can
travel up or down using the surface as the primary means of support
Define "High Angle" - Answer-High angle is a surface or a slope that the FF's full weight
will be borne by the rope at any time
Inventory of the Low Angle Rope Bag - Answer-- 200' Rope (1)
- 12' Anchor Strap (2)
- 20' Webbing (4)
- Short Prusik Sling (2)
- Long Prusik Sling (2)
- Prusik Minding Pulley (1)
- Carabiners (5)
