#515 ITRA Level 3V Swiftwater Theory TEST ONLY - International Technical Rescue Association

The extended platform method for swiftwater vehicle rescue involves:

Using a raft/sled lashed to a ladder and being pushed out to the vehicle (with tag line)
Using an fire service aerial appliance (or snorkel) to gain access to the victims
Creating a zip line on a 45 degree angle, that intersects with the vehicle allowing going out and coming back access
Lowering a raft/sled from a bridge upstream

In regards to glass management during rescue operations involving vehicles in swiftwater, what statement is FALSE?

Be aware of damaged and sharp vehicle body panels including broken or cracked windows

Use spring loaded window punch or window hammer to shatter glass
Side and rear windows are always made from toughened/tempered glass

When using only one rope to secure a vehicle to the shore during a swiftwater rescue…

If the vehicle is on a soft bottom, it may be prone to creating a siphon hazard
If the vehicle is on a hard bottom, it is likely to be very stable.

In high flow situations involving rescue of people from a vehicle on soft ground, the best option for the extraction of heavily pregnant or obese victims is to:

Using a specialist battery powered glass saw to remove the front windscreen to take them through
Remove rear window, lay their seat backwards as flat as possible, and drag them head first via the rear window

Instruct them to exit via the door window head first and position downstream personnel to provide cover

What are common effective tactics when arriving at a vehicle in swiftwater rescue?

If the river width allows, attempt to stabilise the vehicle from the shore with the assistance of the occupant using throwbags and a capture plate
Instruct the occupant to immediately take off their seatbelt and wind down (or break) the door window
If the vehicle is side on to the flow, consider occupants move upstream inside the vehicle to minimise roll over or move onto the vehicle roof if safe to do so
All of these

What statement is FALSE in regards to door management during vehicle rescues (such as the vehicle example below) in the swiftwater environment?

With an engine upstream oriented vehicle, the chance of finger or hand entrapment increases when opening the door.
With an engine downstream oriented vehicle, opening the door may significantly destabilise the vehicle.
With an engine downstream oriented vehicle, the chance of finger or hand entrapment increases when opening the door.
With an engine upstream oriented vehicle, opening the door may significantly destabilise the vehicle.

This swiftwater rescue technique is best described as?

Curtain capture
V lower
Strainer drill
Zip line

Which method best describes deflecting a zip line?

A throwline is held by rescuers on both sides of the river, ideally on a 45 degree angle, and when the victim grabs hold of the rope while floating down the river, one of the rescuers (sides) lets go and the victim pendulums to the shore.
A throwline, from a single side of the river is thrown to form a loop (deflection) around an entrapped person and pulled upstream to release the entrapment.
A throwline is attached to the rear of a PFD’s quick release harness on the rescuer. The rescuer enters the water while the other end of the throwline is held by crew on the shore.
Once a zip line is established, an additional line is attached to the zip line with a moving karabiner to change the angle of the zipline to prevent the load stalling or maneuvering around an object in the water.

[A] accelerate [B] recirculates [C] greater
[A] accelerate [B] recirculates [C] lesser
[A] slow down [B] recirculates [C] greater
[A] accelerates [B] creates a cushion [C] greater

What statement is correct when dealing with wrapped rafts/boats in a swiftwater environment?

The 3:1 or another mechanical advantage (i.e. raft to shore) should generally be the first method to unwrap a boat.
It is important to use additional force, rather than rely on the force of the water to create the pressure required to unwrap a boat.
The two key ingredients to safely and quickly unwrap boats is by shifting weight and/or changing the shape of the boat.
In someone is trapped under a wrapped boat, they generally will have an air pocket so focus should be on quickly setting up a mechanical advantage to free the raft so not to unnecessarily damage the boat.
