A

The apparatus stops near the tire hydrant, and a fire fighter steps off the apparatus and secures the hose around the fire hydrant. Once the hose is secured, the apparatus proceeds to the fire. As the apparatus moves forward, a length of supply hose unfolds from the apparatus and onto the ground.

Q

Describe a horseshoe hose load

A

The horseshow hose load is accomplished by placing the hose on its edge and positioning it around the perimeter of the hose bed in a U shape.

22
Q

What is a major advantage of the horseshoe hose load?

A

It contains fewer sharp bends than the other hose loads.

23
Q

What hose cannot be used for horseshoe hose load and why?

A

A LDH cannot be used for horseshoe hose load because the hose tends to fall over when it stands on its edge.

24
Q

What is the advantage of accordion hose load

A

The load is easy to implement and makes the hose easy to carry.

25
Q

What is the disadvantage of accordion hose load?

A

Hose experience more wear and not recommended for LDH.

26
Q

What is a split hose bed?

A

A hose bed that is divided into two or more sections.

27
Q

What are 4 benefits of a split hose bed?

A

One compartment can hold a hose with a male coupling and the other with a female coupling on top, two parallel hose lines can be laid at the same time, can store hoses of different sizes and all the hose from both sides can be laid out as a single hose line.

28
Q

What is a combination hose load?

A

When a hose from a split hose bed is attached to the end of the last length of hose in the opposite bed to make a long hose.

29
Q

What is the benefit of a dutchman fold?

A

It prevents the coupling from turning and becoming stuck as the hose is laid out.

30
Q

What is the purpose of a supply hose?

A

It is used to deliver as much water as possible over a short distance.

31
Q

What is a working hose drag?

A

It is used to deploy hos from a hose bed and advance the hose line over a relatively short distance to the desired location. Several firefighters may be required.

32
Q

When is a shoulder carry used?

A

It is used to transport full lengths of hose over a longer distance.

33
Q

When is a standpipe system used?

A

It is used to provide a water supply for attack lines that will be operated inside the building. The firefighters inside the building depend on the firefighters outside the building to supply the water.

34
Q

What are the two types of standpipe systems?

A

Dry - depends on fire department for all of the water, Wet - has a built in water supply but the FDC is provided to deliver a higher flow or boost pressure.

35
Q

What is the purpose of a preconnected attack line?

A

The preconnected length of hose and nozzle allow for immediate use.

36
Q

What is a trash line?

A

A short preconnected line that can be used when the apparatus can get close to the fire, such as a vehicle fire or a dumpster fire

37
Q

What do you NOT use a booster hose for?

A

It should not be used for structural or vehicle fires.

38
Q

What is the purpose of a minuteman hose load?

A

It allows a single fire fighter to flake out, or drop, one fold or loop of hose at a time from the shoulder, as they advance towards the fire.

39
Q

What is a preconnected flat hose load?

A

Similar to a flat hose load for supply lines except that the female end of the hose link is reconnected to a pump discharge outlet and a nozzle is attached to the male end.

40

A

It is those places along the hose line where the hose is changing directions, turning a corner, going through a doorway or going up or down stairs.

44
Q

How should you position a hose going around a corner?

A

Pull the hose to the outside of the corner to create surplus hose and avoid contact with the inside corner friction point.

45
Q

How to advance an attack line up a stairway

A

Arrange an adequate amount of extra hose close to the bottom of the stairs. Use a shoulder carry with the minuteman hose load. It is difficult to move a charged hose up stairs with water flowing through the nozzle.

46
Q

What is the best way to advance an attack line down a stairway?

A

Move down the stairway feet first, use your feet to feel for the next step.

A

Should be done before the line is charged. The hose line should be placed across your chest with the nozzle draped over your shoulder.

A

Disconnect the hose from the attack pump and add the extra hose here or add the extra hose at the discharge end of the attack line.

49
Q

What can you use on a defective section of hose is the hose line cannot be shut down at the fire pump, the fire hydrant or at a control valve?
