Q

What is true regarding carrying heavy extension ladders with one fire fighter verse two firefighters?

A

With staffing of four or more on a truck company, the need to single-handedly carry the large extension ladder is outweighed by the efficiency of using more personnel.

A

Masonry firewalls that paraput through the roof may act as one way off of the roof

34
Q

If a portable ladder is to be used for bridging, what type of portable ladder should be considered?

A

Extension ladders should be used for bridging as the ladder is being used against its intended design and the extension ladder provides a more stable surface

35
Q

What four movements should be used when moving in Ariel device from the truck bed to the target to rescue a victim?

A

When using an aerial ladder for rescue, Raise, rotate, extend, and lower into the objective is preferred to ensure the occupant doesn’t jump onto the moving ladder

36
Q

What is the preferred method for entering and exiting the aerial platform when affecting a rescue?

A

Entering and exiting from the platform shall be through the swinging gates and not over the railing if possible

37
Q

 When multiple rescues via the aerial ladder are considered upon arrival to the fire scene, what is the rescue priority based on fire conditions?

A

Occupants most threatened by fire. Apartment directly above the fire.

38
Q

If multiple rescues are to be made using the aerial device in a multi story building, how can the tower operator remove occupants without lowering to the ground level each time?

A

The tower operator can remove occupants to lower levels not affected by fire. This action shall be communicated to the incident commander to ensure companies can assist in the removal of the occupants via interior means

39
Q

Where must the truck company operator be positioned during any rescue operation involving the aerial or when personal ascend the Ariel and enter an IDLH

A

The truck company operator shall not leave the turntable

40
Q

What must the aerial operator do if the aerial encounters in electrical power line?

A

Use the hydraulic controls to move away from ladders if possible.
Stay on the turntable and warn others to stay 30 feet away.
Notify the incident commander.
If the vehicle catches fire, jump from the turntable onto the ground and Bunnyhop for at least 30 feet.
Isolate and deny entry to the area around the vehicle.

41
Q

As a general rule, how far away from the structure should the aerial apparatus be positioned if it is to be used for its elevated stream and there is potential for collapse?

A

It shall be parked from the structure outside the collapse zone, 1.5 times the structure height and or an outside corner

42
Q

Where should the aerial apparatus be positioned to operate master streams with no hazard for collapse exists?

A

When no hazard exists for collapse, position in the area device in front of the fire so that the elevated stream will be most effective

43
Q

What are the three main uses for elevated stream (aerial) operations?

A

Extinguishment.
Exposure protection.
Flying standpipe.

44
Q

What stream pattern should be used on an elevated master stream for attic fires?

A

Narrow fog/straight stream

45
Q

What stream pattern should be used from an elevated master stream for exposure protection?

A

Fog stream

46
Q

What stream pattern should be used from my elevated master stream for a warehouse/commercial building fire?

A

Smoothbore Nozzle

47
Q

When in elevated stream is being prepared to flow onto a fire, but does not yet have water at the nozzle, when should it be rotated into attack position?

A

It shall not be rotated into a tech position until the water is flowing to prevent fire damage to the aerial

48
Q

What smooth bore tip should be used during all elevated master streams?

A

All elevated streams using smoothbore tips should begin with the largest tip available unless directed otherwise, or if it is known that the municipal water supply will not support the flow

49
Q

At what degree should a master stream be directed upward through an open window or opening to achieve the maximum benefit of the stream inside the structure?

A

As a general rule, to achieve the maximum benefit of any stream inside a structure, the stream should be directed upwards at a 30° angle through a window or opening

50
Q

When directing an elevated master stream into a window, how close should the nozzle will be placed to the window opening?

A

The nozzle should be placed as close to the window as possible. If the nozzle cannot position through the window it should position at the level of the sill and flow at an upward angle

51
Q

Why should the elevated master stream be directed to bounce off the ceiling, floor members, or walls?

A

This creates the maximum amount of droplets to absorb the massive amount of BTUs generated by the fire. The steam generated by the broken stream will follow the waves of convection generated by the fire in can extinguish fires in upper floors.

52
Q

Where should the aerial master stream operator start the fire attack if a large volume of fire is on several floors?

A

Attack the fire on the lowest floor first, then move up attacking each successive floor. If a large fire is spreading horizontally, stop its horizontal progress first and extinguish back towards its apparent origin

53
Q

Which stream is typically more effective for sweeping the burning roof material at the roof height?

A

A narrow fog is typically more effective than a smooth board stream for sweeping the burning roof materials at roof height

54
Q

Which Ariel master stream pattern should be used if operating upwards through lower windows into an attic fire?

A

A smoothbore should be used to penetrate the ceiling, as the steam or bounce off the underside of the roof acting as a large sprinkler

55
Q

What size threaded discharge connection is located on the tower bucket to be used in a flying standpipe operation?

A

Most aerial towers will have a small 1.5 inch threaded discharge connection located on the bucket. The main purpose of the hose in connection on the bucket is from mop up in over haul scenarios.

56
Q

If placing an elevated stream into operation after a change in strategic modes, what must be insured through command and verified prior to initiating a water flow?

A

A par check must be completed and insured that no personnel are working in the area where the stream will operate.

57
Q

What level of PPE is required for all personnel operating any elevated master stream?

A

Full PPE and SCBA

58
Q

How should the aerial tower bucket be placed in relationship to a window when used for hasty egress or victim rescue?

A

For hasty egress or victim rescue, the top rail of the aerial tower bucket should be level to the windowsill so a victim may be pulled into the bucket and not needing to use the doors.

59
Q

Where, add a minimum, will most towers have emergency shut off switches?

A

Most towers will have emergency shut off switches at a minimum located in the bucket in on the turntable to prevent accidental operation of the aerial while personnel are operating.

60
Q

What is the effective range in vertical feet that an elevated master stream operation can prevent auto exposure?
