COL Questions With Complete Solutions
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"

rope rescue practices? NFPA 1983
What reference established safety practices and protocols for Permit Required Confined Spaces?
29 CFR 1910.146

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
