First line is in the building. Person is at the window, fire escape, or other exposed position. Immediate application of water is needed. 2nd hoseline should be operated so as not to drive heat, smoke or fire into the building. This is accomplished by operating the hose line into the window at a ———- angle, direct in the stream at the ceiling. The stream should we kept stationary it should not be moved in circular motion that is used to advance an interior hose line. The circular motion can create an air current in the fire area and negatively affect conditions opposite the stream.3.3.5 B.

Standpipe Operations. For residential occupancies what size hose would you use? 4.8.5.

2” lightweight hose as do to relative speed and mobility is more appropriate for the compartment conditions encountered in these occupancies. In other situation, such as commercial, subways, etc. all lengths should be 2 1/2 inch light weight hose.

T/F The presence of commercial occupancy in a OLT with a store does not mandate the use of 2 1/2 inch unless one of the conditions described above is met, the use of 1 3/4 may be appropriate. 4.9.1 A

True Defense Unknown size or extent of fire area Advanced fire Large UNcompartmented fire area

Fire 1 or 2 story taxpayer the large fire area will require use of — hose line. 4.9.1 B.

2 1/2 inch hose line

For fires in a commercial portion of a mixed occupancy building 2 or 3 story building with a store on the first floor and one or two apartments above the use of —- hose may NOT be necessary. 4.9.1 C

2 1/2 These occupancies are usually not more than 50 feet wide

T/F Standpipe equipped buildings. When a hoseline is hand stretched from the appartus into a building with a standpipe the use of 2 1/2 hose is mandated. 4.9.28.

False not mandated This is true for high-rise and low rise fireproof multiple walls. 4.9.3.

When stretching the 1st hoseline, it should be stretched in away to protect the ——- —- of the building while accessing the fire area 5.2

Primary egress PS rare situations, in the building characteristics may need the 1st hoseline be stretched an alternative method. In this case, the path of attack should protect the primary egress as best as possible. These situation situations should be noted In CIDS

NEW Buildings with multiple stairways once the stairway is selected —— —— shall notify the IC of the identity of the attack stairway. 5.3.

Engine officer

NEW Consideration should be given to using the stairway to provide the shortest stretch on the fire floor. This is particularly relevant when —- stairs are used 5.3.1

Scissor Stairs

Consideration should also be given to reserve a evacuation stairway for building occupants. This is relevant if there are multiple stairways, but only one is enclosed in which case it should be used as ——- stairway. 5.3.3.

Evacuation stairway and not for fire attack. Hose line will have to be stretched a different stairway.

Who determines when a well stretch is to be executed. The presence of a well hole and the intention to use. It should be clearly communicated to the nozzle firefighter. This info is critical to the control firefighter for estimating the stretch 5.4.

Engine officer

T/F The presence of a well hold does not mean it must be used. 5.4.1.

True

T/F If the 2nd hose line is stretched, to same location as the 1st line, it should be stretched using the same path as the 1st hoseline and access the fire floor using the same attack stairway. A 2nd dry hoseline should not be stretched into a building until the first hoseline has been charged with water. 5.5.1.

True

Only 2 hoselines ——- be stretched on a stairway 5.6 point

Should

T/F Do not bring an uncharged line to the fire floor. 5.6.3

False It should only be done if the hose can be flaked out AND charged in a safe area before being advanced to the point of operation

Interior stairs Rope Fire escape Portable ladder Aerial ladder I Ran For President, America.

If the door to the fire department or fire area is controlled and conditions in the public hallway are tenable, the hose should be flaked out and charged ————-. 6.4

At the apartment door.

Exterior fire between buildings. If the fire is showing on the exterior between two buildings and it is unclear, which of the two is the original fire building, the first hose line may need to be charged and operated from the ————of the building hitting the ——— point of fire first and moving the stream down to the fire base to determine from which building if any of the fire is extending. 7.7.8.

Exterior Highest PS if this first hose line is repositioned a subsequent hoseline should be placed to ensure the exterior fire does not reignite.

Members inside the building ——- be notified that an exterior stream will be utilized and positioned to a safe area prior to water application. 7.8.1

Should

When using an exterior hoseline stream should be operated at a ——- angle by placing members as CLOSE to the structure as possible. 7.8.2.

Steep angle PS aim water towards the ceiling

Operation of an exterior stream. How do you create a tight stream which minimizes air entrainment? 7.8.4

Nozzle should be fully opened as a fully opened smooth bore nozzle creates a tight stream which minimizes air entrainment.

Exterior handline. After operating it off of the ceiling, the stream should be moved upwards towards the —- of the ——— and operate for a few seconds. 7.8.5.

Top of the window opening (lintel) and operate for a few seconds off of the lintel.

Exterior handlines only be used as long as necessary to visually see improvement in the fire conditions. Normally this is approximately? 7.8.6.

Approximately 10 seconds

Manual technique of applying water correctly from an exterior handline to the interior of a building is? 7.9

SSSS Solid bore stream (full open) Steep Angle Steady (no circular or whipping motion) Sprinkler

Exterior stream. If another hoseline is not available, the hoseline operating from the exterior must be repositioned to the interior as soon as the fire is? 7.13.

Sufficiently knocked down

In all cases, exterior hoseline operations need to be communicated to and coordinated by? 7.14

Engine officer should confirm with whom before calling for water? 8.1.2.

Nozzle and back up firefighters.

At standpipe Operations a ——- will be necessary to allow control firefighters to properly set the operating pressure at the standpipe outlet. 8.2.1

Long bleed PS same concept applies when a 2 1/2 inch hose on a stretch from the apparatus.

T/F The nozzle team must begin every interior fire attack through the door to the fire area, crouched low, near the floor, regardless of conditions 8.5

True Reason, sudden ceiling collapse, rapid self venting or wind, driven fire.

Who makes the decision to open the nozzle 8.6

Engine officer

Do we open the nozzle on smoke? 8.6

Yes, you can, smoke is to be considered fuel and flowing water on the approach of the fire can cool the fire area preventing flashover and rapid fire development.

T/F If turbulent smoke is encountered at the entry point, the nozzle should be opened and operated at this location until is able to advance 8.6.1

True

Once the hoseline arrives at the fire area the line should be operated into the overhead area initially to wet the ceiling and adjacent walls, then lowered to hit burning objects in the room, then ——- the floor and enter for final extinguishment. 8.6.5

Sweep

The engine officer should be positioned as close as possible to the nozzle firefighter, but needs to avoid ——— ——— the nozzle and backup firefighters. The backup firefighter needs to maintain contact with the nozzle firefighter in order to support them as they operate the hoseline. 9.3.

Coming between

In open spaces or wide hallways, an ideal position for the engine officer would be? 9.4

Directly alongside the nozzle firefighter

In narrow hallways, cluttered or crowded spaces, and smaller areas, the position for the engine officer would be? 9.5.

Either behind the back up firefighter or in front of the nozzle itself. If conditions allow.

The preferred position in a tight hallway for the engine officer would be 9.5.1

Behind the back up firefighter

Touch signals with verbal commands for the engine Open or close the nozzle? 9.7.1.

One or two slaps on the back or shoulder

Touch signals with verbal command commands for the engine. Direction of stream? 9.7.2.

Tug on the arm or nozzle either left or right

Touch signals with verbal commands for the engine. Advanced hoseline? 9.7.3

Steady push on back or SCBA

Touch signals with verbal commands for the engine. Stop line advance? 9.7.4.

Pull back on shoulder, bunker coat or SCBA

Touch signals with verbal commands for the engine. Emergency withdrawal? 9.7.5.

4 slaps on shoulder and pull in direction of retreat

Touch signals/verbal commands for engine. 1-Open and close nozzle? 2-Direction of stream? 3-Advanced hose line? 4-Stop line advance 5-Emergency withdrawal? 9.7.

1- 1 or 2 slaps on back or shoulder 2- tug on arm or nozzle either left or right 3- steady push on back or SCBA 4- pull back on shoulder, bunker coat, or SCBA 5- 4 slaps on shoulder and pull in direction of retreat

T/F Advanced Celler fire, if flames are visible from the top of the stairs, the line should be opened to knock down the fire from this position and quickly advance to the bottom of the stairs. 9.10

False In a Non-Fireproof structure OLT, taxpayer, row frame, etc. it is frequently safer and more efficient to initially attack the fire by using and exterior entrance if such access exists. PS if the word advanced is not used, then you can do what it says in the question.

When does the engine officer order the nozzle to be shut down? 9.11

After all visible fire has been knocked down PS only the engine officer may order the nozzle shut down.

After final extinguishment the engine officer may also order a —— or —— directed at the window in the fire area to assist and removal of heat and smoke conditions.. 9.12

Fog or broken stream

How do you create a broken stream for venting. 9.12

Removing the MST and partially shutting down the control handle.

2nd arriving engine officer responsibilities upon arrival must ensure? 11.2.

The 1st arriving engine has a positive water source

T/F 2nd arriving engine when assisting the 1st arriving engine, the 2nd arriving engine officer should ensure their members are spread out on the line and position themselves out of the IDLH if possible. 11.3

True

When arriving as a later assigned engine at a multiple, the engine officer should anticipate the possibility of stretching a line into the building by an alternate means ( rope, stretch, fire, escape, stretch,etc) with this in mind, the engine officers should report in with the necessary tools, such as? 13.1

Rope Hose Roller ETC

Before stretching a hoseline from an apparatus the office who should confirm with the —-———- that the apparatus has enough water capacity supply their hoseline 13.3
