Question 1

Which throw bag deployment technique is best when the victim is close and time is critical?

Accepted Answer

Coiled underhand with bag held in non-throwing hand

Answer

The coiled underhand throw with the bag in the non-throwing hand and coils in the throwing hand offers accuracy and speed for short-range rescues.

Question 2

When rescuing a victim in a hydraulic (hole), a throw bag should be aimed:

Accepted Answer

Just downstream of the hydraulic's boil line

Answer

Throwing the bag to land just downstream of the boil line allows the victim, if they escape the recirculation, to grab the rope as they exit.

Question 3

What is the recommended minimum number of shore-based personnel for a live bait rope rescue?

Accepted Answer

3 rescuers — one swimming, two managing the rope

Answer

A minimum of three personnel is needed: one tethered swimmer and two shore-based rope handlers to manage the load and control the pendulum swing safely.

Question 4

What is 'rope entrapment' in swiftwater rescue?

Accepted Answer

A rope looping around a victim's limb or body part and pinning them underwater under current force

Answer

Rope entrapment occurs when current forces drive a rope loop against a victim's body or limb against a fixed object, creating a potentially fatal pin.

Question 5

A throw bag rope rated at a 'working load' should be used at what fraction of its minimum breaking strength (MBS)?

Accepted Answer

1/10 (10%)

Answer

A safety factor of 10:1 (working load = 10% of MBS) is standard for life-safety rope systems to account for dynamic loads, wear, and repeated use.
