Inland Water Rescue & Emergencies 2019

Question 1

This feature is evident downstream of low head dam type hydraulic. It marks the area where the current splits direction of flow. The lighter aerated water further upstream is moving back towards the hydraulic while the darker water is moving downstream.

Answer 1

Boil Line

Question 2

A reversal of water flow from downstream to upstream, caused by a negative pressure void formed by passing water.

Answer 2

Eddy

Question 3

Using the force to assist the movement of a boat or a swimmer’s body to the target. Maintaining a 45 degree angle to the current the swimmer or boat can traverse the water with less difficulty.

Answer 3

Ferry Angle

Question 4

As water passes along the sides of the shore it creates circular swirls resulting from friction. This pattern lends itself towards drawing water from the shoreline and pulling it in towards the main current flow in the center.

Answer 4

Helical Flow

Question 5

Water pouring over an underwater feature creating a void that will be backfilled by water traveling the opposite direction (upstream)

Answer 5

Hydraulic

Question 6

Area in or over the water/ice is considered the IDLH.

Answer 6

Hot Zone

Question 7

Area within 10 feet of the water/ice. PFD’s are required.

Answer 7

Warm Zone

Question 8

Area greater than 10 feet from the water/ice.

Answer 8

Cold Zone

Question 9

Object or structure that allows water to pass through but not the rescuer.

Answer 9

Strainer

Question 10

Victim Recognition: Everyday swimmer, no trouble following commands and assisting in own rescue.

Answer 10

Normal

Question 11

Can follow simple commands, can usually help themselves with proper direction.
