Question 9

Those places where a hose line encounters resistance, such as corners, doorways, and stairs.

Answer 9

Friction points

Question 10

A hose and nozzle that can be held and directed by hand.

Answer 10

Handline

Question 11

A hose loading method in which the hose is laid on its edge around the perimeter of the hose bed so that it resembles a horseshoe.

Answer 11

Answer 15

Split hose bed

Question 16

A scenario in which the attack engine forward lays a supply line from an intersection to the fire, and the supply engine reverse lays a supply line from the hose left by the attack engine to the water source.

Answer 16

Split hose lay

Question 17

Answer 17

Supply line operations

Question 18

A hose loading method in which the hose is folded back onto itself to reduce the overall length to one-third before loading the hose into the hose bed. This load method reduces deployment distances.

Answer 18
