53
Q

To place portable monitors into operation, the following steps are necessary:

A

Place the monitor in the desired location.

Connect hose lines to the intake(s), allowing for approximately 15m of slack for repositioning.

Make sure that hose lines are led in from straight behind (minimum 2 meters).

Before the monitor is charged with water, make sure the footing is secure.
** The monitor’s reach of stream is most effective at 35 degrees of elevation. Care must be taken when operating below 35 degrees due to nozzle reaction. **

59
Q

siamese

When using charged lines on a ladder the hose can be secured to the working side or in the center of the ladder as circumstances dictate

61
Q

A

used to tighten or loosen intake hose couplings equipped with extended lugs

62
Q

TFT 125mm hydrant gate

o Hydrant wrench
o Hose spanners
o Hydrant gate

64
Q

CFD teaches five methods for coupling/uncoupling hose

A

One firefighter foot tilt method

Two firefighter method of coupling a fire hose

One firefighter knee press method of uncoupling

Two firefighter stiff-arm method of uncoupling a fire hose

One-firefighter over the hip method

65
Q

anatomy of a hydrant

A
66
Q

opening hydrants

A

slowly open the hydrant valve until water begins to flow past the seat. Pause to allow the pressure in the barrel to equalize on both sides of the valve before continuing to fully open the hydrant slowly.

Allowing pressure to equalize before opening fully prevents water-hammer and reduces torsional stressors on the hydrant valve stem and couplings

Slowly continue to open the hydrant until fully open, and then turn the hydrant key back one full turn

67
Q

hydrant closing procedure

A

set the spindle into the neutral position

The neutral position is located by rotating the operating nut from the fully closed position in a counter-clockwise direction until you feel resistance on the key. Resistance on the hydrant key is caused by the valve starting to open, pushing the disc against the water pressure in the main. The operating nut must be left in the midpoint between fully closed and starting to unseat the disc.

68
Q

hydrant evolutions or “lays” can be divided into the following

A

forward lay
reverse lay
initiating a relay operations (cutting in)

69
Q

surfing the line

A

term used to describe the procedure for deploying the125 mm hose during reverse lay operations

For safety, it is preferred to surf the hose on the opposite side to the traffic flow.

Position yourself so that the driver can see you in the mirror

Fold the hose back onto itself so that the coupling is in front of the firefighter performing the surfing

Remain surfing the line until 1 - 2 lengths of hose have been deployed and the firefighter no longer feels tension of the hose being pulled

70
Q

estimating the stretch

A

estimate the known distance
estimate the foot print size
calculate the number of floors

71
Q

estimate the known distance

A

Visible distance from the apparatus to the door of entry

72
Q

estimate the foot print size

A

one length should be able to cover a square floor area of 2000ft2

73
Q

calculate the number of floors

A

add one length of hose for every level

74
Q

flaking the hose

A

Lay the hose on the ground so that it extends to the point of entry. Ensure that there is sufficient covering amount and that the hose is free from kinks and will pay itself into the building with limited chance of snagging on the way once charged with water

75
Q

3 common techniques of flaking hose

A

S flake (most common)

U flake (quick option in areas where space is not a problem)

Coil (ideal for limited space/stairwells)

76
Q

Coil (ideal for limited space/stairwells)

A

should never be smaller than 1 meter (40inches) in diameter

77
Q

traditional V stretch

A

used when space is not an ussie and when there are limited obstructions between the engine and the entry point

78
Q

hose handling - 44mm handline

A

requires a min of 2 FF for interior attack

79
Q

hose handling - 65mm handline

A

requires a min of 3 FF for interior attack

80
Q

hose grips

A

tanaka
clamp
65mm pressure loop

81
Q

tanaka grip

A

This technique uses the firefighters skeletal system to take the reactionary force created by the hose line, instead of the using their muscles to counter act force

82
Q

clamp grip

A

This technique uses the firefighter’s body weight and low center of gravity to pin the nozzle to ground using back leg and shin thus reducing firefighter fatigue.

83
Q

65mm pressure loop

A

This technique allows a single firefighter to operate a 65mm hose line for long periods unassisted.

It should only be used in an exterior application where the firefighter can set up without being in the collapse zone as it may prohibit quick egress by the firefighter

84
Q

advancing hose lines

A

over the shoulder
straight arm pull
modified straight arm pull
clamp slide

85
Q

advancing hose lines - over the shoulder

A

this method uses firefighter skeletal system to take majority of the weight of hose line instead of using smaller muscle groups

86
Q

advancing hose lines -straight arm pull

A

Allows for quick movement that can be sustained for moderate distances

87
Q

advancing hose lines - clamp slide

A

Used for advancing both 44mm and 65mm hose lines over short distances

This technique can be used while spraying water

88
Q

feeding hose

A

All firefighters within the team must have physical contact on the same hose line and have verbal or visual contact.
