Ops – COL Exam Questions and
Answers 100% Pass
How do knots affect rope strength and efficiency? - ✔✔Knots will cause a loss of 30%
rope strength overall. Sharp/acute bends increase loss of efficiency as only part of the
rope is supporting the load.
What are the three procedures to tie a knot? - ✔✔Dress, load, and safety the knot.
What are the min and max tail lengths for webbing and rope? - ✔✔Rope: 2-10"
Webbing: 3-5"
What reference developed the standards for safety concerning rope, harnesses, and
equipment for rope rescue practices? - ✔✔NFPA 1983
What reference established safety practices and protocols for Permit Required Confined
Spaces? - ✔✔29 CFR 1910.146
What is the minimum breaking strength (MBS) for one and two person rope? - ✔✔One:
4500lbf MBS

This type of rope is surrounded by a woven sheath or _____. The internal core or _____
is made of synthetic fibers. - ✔✔Outside: Mantle
Inside: Kern
What are the two types of kernmanle rope? What are the differences in their stretching
capacity? - ✔✔Static is a taught rope that stretches around 5% with a 220lb load.
Dynamic stretches around 20%, making it better for rappelling and mountaineering.
NFPA 1983 states that rope must be inspected before and after use by
_______________________ - ✔✔Inspect the ropes by sight and touch. Run the entirety of
the rope through your bare hands to feel for any damage.
When must rope be retired? - ✔✔After 10 years, severe shock or degradation (dropping
or overloading), misuse, contamination, internal fibers are visible through the mantle,
unsure history
What is the Static System Safety Factor (SSSF)? What is the ideal ratio? - ✔✔SSSF is the
ratio of load to the strength of individual components of the system (ropes, pulleys,
harnesses, etc.);
