SRT Rescue Techniques and Operations 2

Question 1

When performing a live-bait rescue in swiftwater, which body position should the rescuer maintain while being swept downstream?

Accepted Answer

On their back, feet downstream, toes up

Answer

The defensive swimming position—on your back with feet downstream and toes up—protects the rescuer from foot entrapment and allows them to push off rocks.

Question 2

A 'strainer' in swiftwater rescue terminology refers to:

Accepted Answer

An obstruction that allows water to pass through but traps solid objects

Answer

Strainers (e.g., fallen trees, rebar, fences) are among the most lethal swiftwater hazards because water flows through while a victim is pinned against them by hydraulic force.

Question 3

What is the primary advantage of a vector pull (V-pull) when extracting a pinned boat?

Accepted Answer

It multiplies force by creating a perpendicular angle on the tensioned line

Answer

A vector pull applies a perpendicular force to a tensioned line, creating significant mechanical advantage that can multiply the input force several times over.

Question 4

During a helicopter rescue over moving water, the primary hazard of static discharge is mitigated by:

Accepted Answer

Allowing the rescue line or basket to ground in the water before touching it

Answer

A hovering helicopter builds up significant static charge; allowing the line or basket to touch water or ground first dissipates that charge before rescuers touch it.

Question 5

Which knot is most commonly used to tie a tensionless hitch for anchoring in a swiftwater highline system?

Accepted Answer

Tensionless wrap (tree saver)

Answer

The tensionless hitch (multiple wraps around an anchor with a locking carabiner) preserves nearly full rope strength because the load is distributed across the wraps rather than a single knot.
