RRC Rope Systems & Throw Bag Techniques 3

Question 1

In a 'live bait' rescue, the rope is attached to which point on the rescuer's body?

Accepted Answer

Waist, using a quick-release PFD tow belt

Answer

The rope is attached to a quick-release tow belt at the rescuer's waist so the rescuer can swim to the victim and instantly shed the rope if entangled.

Question 2

What is the primary safety hazard when using a fixed rope (line) for assisted wading rescues in swift current?

Accepted Answer

The rope can pin a rescuer against a submerged obstacle if they fall

Answer

A taut fixed line can act as a trap, holding a fallen rescuer underwater against a submerged rock or strainer where current keeps them pinned.

Question 3

What does the term 'rope entrapment' mean in a swiftwater rescue context?

Accepted Answer

A person becoming caught or pinned by a rope under hydraulic pressure

Answer

Rope entrapment occurs when hydraulic forces trap a swimmer against a rope stretched across current, which can be more dangerous than the original hazard.

Question 4

A 'vector pull' technique applies force to a tensioned rope perpendicular to its length. What is its practical use in river rescue?

Accepted Answer

To shift a pinned boat or object using minimal force by deflecting the midpoint of the rope

Answer

Applying sideways force to the midpoint of a tensioned rope creates a large mechanical advantage that can un-pin wrapped boats or move heavy loads with less effort.

Question 5

How should rescue ropes be stored after use in river operations to maintain their performance characteristics?

Accepted Answer

Loosely coiled, rinsed with fresh water, and stored away from UV, heat, and chemicals

Answer

Polypropylene and nylon ropes degrade when exposed to UV light, heat, and chemicals, so rinsing and dry storage in a dark, cool location extends service life.
