Ch6 supply hose loads and deployment procedures

Question 1

forward lay

Answer 1

hose is laid from the water source ot the fire/emergency scene, female coupling is deployed first

Question 2

reverse lay

Answer 2

fire hose is laid from the fire to the water source, male coupling is deployed first

Question 3

The reverse lay is used when?

Answer 3

hydrant spacing is under 200 feet, the driver operater can see the incident scene, the water pressure is low(under 40 psi), and the supply line is over 500 feet

Question 4

split lay

Answer 4

is a hoseline deployed in part as a forward lay and in part as a reverse lay by two pumping apparatus from a point between the incident and the water source

Question 5

dual lay

Answer 5

The term dual lay can refer to any one of a number of ways to deply multiple supply hoselines; two or more same-sized hoselines deployed as supply hoselines by one pumping apparatus

Question 6

combination lay

Answer 6

when two different-sized hoselines are deployed form one pumping apparatus and laid parallel to each other

Question 7

A blank hose bed with 2 hose sizes offers the command officer a number of choices when determining the best way to commit limited resources

Answer 7

divided

Question 8

what are the three basic hose loads?

Answer 8

accordion, horseshoe, and flat

Question 9

what is a combination load

Answer 9

in a divided hose bed, where one side is set up for a forward lay and the other side is for a reverse lay

Question 10

blank has a direct bearing on the manner in which hose is loaded and deployed and on the size of the hose used

Answer 10

pump size

Question 11

accordion load

Answer 11

hose is laid preogressively on edge in folds that lie adjacent to each other

Question 12

advantages of an accordion load

Answer 12

simple design for ease of loading, hose for shoulder carries can be easily taken from the load by simply picking up a number of folds and placing them on the shoulder

Question 13

disadvantages of an accordion load

Answer 13

hose contains sharp bends which require it to be reloaded periodically, hose tends to wear on its edges, this load is not recommended for LDH

Question 14

horseshoe load

Answer 14

it is loaded on edge but it is laid around the perimeter of the hose bed in a U-shape configuration

Question 15

advantages of a horseshoe load

Answer 15

fewer shap bends in the hose

Question 16

disadvantage of a horseshoe load

Answer 16

hose sometimes deploys in a wavy or snakelike pattern lay in the street as the hose is pulled, 10 -15% of the total length will be lost, shoulder folds cannot be obtained as easily, not recommended for LDH

Question 17

flat load

Answer 17

where the hose is laid so that its folds lie flat rather than on edges

Question 18

disadvantages of a flat load

Answer 18

folds contain sharp bends, requiring the hose to be reloaded periodically, requires 2 persons to make folds for shoulder carries

Question 19

An apparatus configured to carry large diameter supply hose on a reel is often designated as a?

Answer 19

hose wagon

Question 20

In jurisdictions where the primary water source is a water system with hydrants, it is usually best to use the hydrant closest to the fire scene. true or false

Answer 20

true

Question 21

the procedure for anchoring and connecting hose to a hydrant starts when the driver/operator stops the pumping apparatus with the tailboard approzximately blank feet past the hydrant

Answer 21
