Q

Where heat conditions require a very LOW APPROACH to the fire area?

A

CRAWLING

17
Q

Where rubble/debris cannot be swept and may cause injury to nozzle team?

A

DUCK WALK

-beneficial in OFFICER/PROJECTS with concrete floors

18
Q

Where the INTEGRITY OF FLOOR IS IN DOUBT….use?

A

LEG FORWARD (OUTSTRETCHED LEG)…..used to feel for holes in floor before full weight of FF moves forward

-good in COMMERCIAL PREMISES

19
Q

Stream is directed?

A
  • forward and upward
  • side to side rapid/clockwise motion
  • as progress is made,lower towards main body of fire
20
Q

Stream should NOT be operated directly overhead….EXCEPTIONS:

A

EMERGENCY:

  • ROOM LIGHTS UP OVERHEAD
  • FIRE ROLLS OVERHEAD FROM BEHIND
21
Q

CARDINAL rule of Engine?

A

DO NOT PASS FIRE

22
Q

“KNOCKDOWN” means?

A

CONTROL OF FIRE ARE

without

complete extinguishment

23
Q

If it becomes necessary to withdraw an attack hoseline from a position due to fire intensity…

A

steam MUST be kept in operation and the line should be BACKED OUT.
-FF withdrawing hosline should NEVER turn their back on fire

24
Q

When Nozzle FF wants to change direction or elevation of the stream, BACK UP must maneuver the section of hose behind nozzle in ?

A

opposite direction

-initially back up must maintain hoseline BELOW the operating nozzle and keep line STRAIGHT as possible

25
Q

Door FF:

A

assist in flaking out
maintain BOW/RISE
do not push nozzle team
MONITOR /OBSERVE HEAT, SMOKE, FIRE at entrance doorway

26
Q

Most important ?

A

CONTROL position

  • PRIMARY FUNCTION to assure CORRECT AMOUNT OF HOSE
  • minimize number of lengths to reduce friction loss and kinks
27
Q

Assigning Control to DETAILED LADDER MEMBERS or unfamiliar (with building types /apparatus ) Engine members should?

A

be AVOIDED

-where possible, most experienced and knowledgeable

28
Q

Factors when estimating stretch:

A
  • distance from apparatus to building entrance
  • distance to foot of stairs
  • type of stairs
  • number of floors
  • distance to fire area
  • size of fire area
29
Q

Control FF must remain LAST IN STRETCH, in order to keep track of number of lengths ….must complete control function (whether assisted or not), prior to other functions

A

especially true with BACK STRETCH…when ECC is waiting for sufficient hose to be removed prior to proceeding to a hydrant (if control leaves back step area, ECC will be delayed, as will water on the fire)

30
Q

T or F….First Due control can delegate or transfer the control position to the second due control firefighter

A

FASLE

FIRST DUE CONTROL should NOT DELEGATE control duties to 2nd due control

1st due control should remain at the hose bed and complete the hose estimate and removal

31
Q

When is CONTROL’S HOSE ESTIMATE FUNCTION considered complete?

A

A. required number of lengths is removed from bed, line is broken and connected to a pump discharged outlet (this occurs when hydrant is in close proximity to fire building or ILP is used and apparatus will remain near front of building)

or

B. required number of lengths is removed from bed, and control FF signals to ECC to proceed to MORE DISTANT hydrant (back stretch)

32
Q

After ESTIMATING STRETCH, control fF must?

A
  • assit ECC with hydrant connection (fire on lower floor/hydrant in close proximity)
  • flake out hose between apparatus and building entrance door
  • check any doors that dry line is stretched through to ensure chocked open
  • eliminate kinks in the CHARGED HOSELINE while moving toward fire area
33
Q

Single 90 degree kink in a 1 3/4” hoseline can result in a loss of 20 gmp or more

A

successive kinks have cumulative effect—3 kinks, 90 gPm or more , ineffective and unsafe stream

34
Q

2nd Engine:

A
  • assist stretching initial handline
  • assure first due engine is connected to adequate water supply
  • relieve first due engine personnel
35
Q

2nd Engine OFFICER:

A
  • WATER RESOURCE for first hoseline
  • PROVIDE COMM LINk between first due engine and IC
  • CONTROL number of members on fire floor
  • keep track of members going to FLOOR ABOVE (before fire is controlled)

all members going above (before fire is controlled) shall communicate identity to 2nd due engine before proceeding above

36
Q

2nd ECC .., position apparatus and TEST , ?

A

prior to assisting first due ECC

-monitor Dept. radio and answer for BATT or Div aide

37
Q

When 10-70 is give, who is water resource UNIT?

A

2ND DUE ENGINE

38
Q

If ladder company is forcing door..engine officer can proceed to area BELOW FIRE ARE..

A

determine layout
-look at ceiling for signs of weakness
-look out a window determine fire location
look out stairway window.

39
