Q

What are the methods of rolling hose? And describe each one.

A
  • Service Roll, Male coupling at the core. Used when cleaning up hose and storing on racks
  • Damaged Roll, female coupling at core. Hose that needs to be repaired.
  • Single Doughnut Roll, 125mm pony, hose will be used directly from its rolled form. Both couplings on the outside

Q

When should hose testing and inspections be done?

A
  • Annually
  • After repairs
  • After hard use
  • On any suspicious of damage

Damaged hose should be tagged and marked and a FD1205 made and sent into stores

17
Q

What are we looking for when we inspect the hose prior to testing?

A
  • Vandalism
  • free of debris
  • mildew or rot
  • chemical damage
  • burns or cuts
  • excessive abrasion
  • vermin damage
  • internal inspection at couplings for delamination of liner
18
Q

What are we looking for when we inspect the hose couplings prior to testing?

A
  • Damaged threads
  • corrosion
  • slippage on the hose
  • out of round
  • connections no roating freely
  • missing lugs
  • loose external color
  • internal gasket
19
Q

What is the color of the first and second transverse hose loads?

A
  • first is yellow 44mm second is orange 44mm
20
Q

What is the coupling part of the truck the transverse loads are connected too?

A

supply header

21
Q

What are the components of a leader line/ transverse load?

A
  • 4 lengths of 15m hose (44mm or 65mm), preconnected to each other and the truck, with a nozzel.
22
Q

What row of the transverse hose do you make the grab loops? How long should they be?

A
  • The second and third rows for the first set at 15-20cm (height to reach the side of the hose bed)
  • The second set of grab loops is after the second coupling has been placed. approx. 15 cm or height of the hose bed.
23
Q

Describe the 65mm attack bed. How many total length, and of what kind of load?

A
  • 18 lengths of 65mm, 3 loads of 6 lengths (666)

- 2 rows of fast attack and 1 row of shoulder load.

24
Q

What sex of coupling is loaded first in the fast attack and shoulder load?

A
  • Fast attack: female

- shoulder load: male

25
Q

Aprox how long should the grab loops be in the shoulder load? Do you need to use setbacks to prevent the load from bananaing?

A

4-6 inches and no setbacks in this load.

26
Q

How deep should the setbacks be for the fast attack loads? How deep for 125mm supply bed?

A
  • 2 inches fast attack

- 4 inches supply bed

27
Q

How many firefighters are needed for loading each type of hose load?

A
  • Scorpion/ bumper 1
  • transverse lines 3 (1 on each side, 1 up top)
  • devils load 3 (2 up top, one on the ground)
  • supply bed 4 (2 in the bed, 1 on the tailboard, 1 on the ground) can be done with 3, tailboard and ground is 1 guy
28
Q

What is the name for the 125mm supply bed load

A

coupling forward column load post 2016 engines and all quints

29
Q

What are the 2 hose bundles?
How are the couplings orientated?
How long is the fold?

A
  • Single length of 30m 44mm
  • Single length of 15m of 65mm
  • 44 has male coupling on the inside with TFT nozzle, female coupling is on the outside of the same side
  • 65 has the male coupling on the inside with the female coupling attached to it to protect the threads.
  • 32 inches from the tip of the male coupling
