I have been doing a BSA course this week for rappelling. I really didn't know how much I belonged on @Deathcricket (http://www.bogley.com/forum/member.php?u=278)'s "Z-Crew" before now. I have always gone rappelling with as few of knots possible but this course is all about knots, and numbers (so far).
Here are the notes from the BSA Course Test:
Knots:
• Water knot
• Figure 8 knots
o Figure 8
o Double Figure 8
o Finished up in a Yosemite
• Prusiks
• Munter Hitch
• Mule Hitch
• Alpine Butterfly
• Tied Harness
Setup:
• Top Belay
• Fireman’s Belay
• Z-Rig Rescue Setup
Edge:
Explain
Demonstrate
Guide
Enable
Check:
Clothes
Harness, Helmet, Hair
Environment
Connections
Knots
Earnest
• Equalized. Develop each anchoring system so the load is distributed as equally as possible among all the anchor points. That will reduce the strain on a given point and reduce the chances of any of the points failing.
• Angle. Keep the angle less than 90 degrees between the outside legs of the anchor system, unless the anchoring system is designed for larger angles. Belay cable systems with 10 percent drape form much larger angles but are designed to withstand much higher forces.
• Redundant. All anchors must be fail-safe or backed up. If you have even the slightest suspicion that an anchor is anything but completely reliable, build enough redundancy into the system so that the failure of an anchor will not imperil a climber, rappeller, or belayer.
• No extension. If an anchor point fails, the anchor system will not extend and be shock loaded.
• Solid. Anchors must be reliable. There is no room for compromise. Take all the time you need to do the job right. If you are unsure of your expertise, find someone who is qualified to provide guidance.
• Timely. Use your time wisely and efficiently. Send staff ahead to set up so that the program is ready to go when the participants arrive. Watch the weather
Random:
• The breaking strength of carabiners must be 5,000 pounds
• Static pulley doesn’t help but a moving pulley does
• 6 minutes of staying still on rope can be lethal. Must encourage stuck rappeller to keep their legs moving regularly to prevent blockage.
