18
Q

Prior to establishing water supply ___________ must be notified to Engine OIC

19
Q

Prior to establishing water supply _________ can be charged

A

only one attack line

20
Q

Prior to establishing water supply additional lines can be charged for

What must be notified to crew using these lines

A

Exposure Protection

Line to the Attic

RIT

Controlling exterior fires

Engine driver advises the requesting officer that water supply has not been ESTABLISHED

21
Q

Evacuation Order

A

Given verbally, signaled over radio via tones or blasted over on-scene apparatus airhorns

22
Q

Signs of Backdraft

A

Dense Smoke no visible flame

Black Smoke Pushing around closed doors

Stained Glass

Air Movement Reversal

23
Q

HRR

A

Heat Release Rate

24
Q

Forward Lay

A

Places Supply line at closest hydrant preceding the incident

25
Split Lay
Supply Line dropped off at intersection 2nd engine can complete or 3rd engine create a relay
26
Reverse Lay
2nd Arriving engine lays out from scene to hydrant Mindful of narrow streets and poorly positioned apparatus
27
Nozzle Reaction explanation
Force produced at nozzle and transmitted backward while flowing the stream 2 factors: Nozzle Pressure & Flow
28
Stream Velocity Formula
12.14 x √NP = ft/s directly related to nozzle pressure
29
Drivers ultimate responsibility
Safe Delivery of personnel to and from scene
30
Engine Positioning
Position to create the most direct access for advancing attack hoselines allowing truck company to position directly in front
31
Misc Engine Driver Duties on fireground
Placing portable ladders and advancing exterior hose lines
32
Offensive vs Defensive
Offensive mode involves taking direct action to mitigate the problem (Direct Fire Attack) Defensive: Used to prevent damage to the area around a structure
33
2 1/2 hoseline is typically appropriate for fires in..
Commercial Buildings Exterior Attacks Exposure Protection
34
Residential Roadway width is in average how many feet
12 ft
35
Dimensions of a single vehicle driveway
12 ft wide by 25 ft long
36
Grimwood Maximum Nozzle reaction firefighters can handle
1 FF = 60 lbf 2 ff = 75 lbf 3 ff = 95 lbf
37
How does Increased fire-stream velocity help combat large volume fires
Lessens negative impacts of wind and heat on streams Streams hit harder and better distribute water
38
Describe Blitz Attack Transition should be ________ and _________
Use of exterior master streams to knock down main body of fire Once darkened down the engine company transitions to handline transition should be rapid and coordinated
39
Drivers must choose the appropriate ________ that allows for a ______ _______ while leaving access for the remainder of the assignment
Must Choose the Appropriate Intake that allows for a quick connection while leaving access for the remainder of the assignment
