Close to the primary knot.

Question 4

Prussic Cord

Answer 4

• We use two sizes
  - Black 54”
  - Green 65”
• We use these for backups in life safety rescues. Use two of these in tandem to anchor the rope if it slips. We secure the prussic cords.
• When mining the Belay Line if the person falls let go of the prussics and the friction will stop the rope from falling.
