Question 6

Fires in vapors of ______________fuel develop slowly at the start, but progress rapidly as vapor production intesifies. Heat developed will be for a longer duration than that involving gasoline, igniting more of the combustible materials in the area

Answer 6

diesel fuel

Question 7

Answer 7

gasoline

Question 8

All members responding to vacant building fires, (especially ___________ & _________ ff’s) are cautioned to note the method used to seal these buildings in their size-up

Answer 8

roof/outside vent

Question 9

Proper size-up is most important for the officer in command. In execution of the fire attack plan, the same order of priorities apply as in firefighting in occupied buildiings, i.e. _______, _________, ________ & _______

Answer 9

life, exposures, confinement, & extinguishment (L.E.C.E.)

Question 10

What is the most important aspect in determining the initial attack strategy (interior or exterior)?

Answer 10

Structural Stability

Question 11

The officer in command at a vacant building fire must take into account how many sides of the building?

Answer 11

six sides (four sides at the same level, as well above and below)

Question 12

What is the most important consideration in size-up at a vacant building fire?

Answer 12

Protection of life

Question 13

When a vacant building is heavily involved on arrival, where are the first hose streams placed?

Answer 13

between the involved building and the most “severe life exposure”

Question 14

When a vacant building is heavily involved on arrival and no life is endangered in the exposures, where do you position the first stream?

Answer 14

to protect the greatest amount of property

Question 15

What does “R.O.” over the vacant building marking mean and where is it placed?

Answer 15

Roof Open – if the roof has been previously opened or burned away, to the degree that the need for future vertical ventilation appears minimal, place R.O. over the vacant building marker (and both inside and outside of the bulkhead as well)

Question 16

What are advantages of in-line pumping?

Answer 16

1) fast water on fire – 2) pumper in position for exterior stream – 3) equipment on pumper closer to fire – 4) shorter/faster hand liine – 5) lower engine pressure – 6) ECC in better position to observe op’s if needed

Question 17

What are disadvantages of in-line pumping?

Answer 17

1) water supply limited to line layout/hydrant potential – 2) it may not be possible to attain full pumper capacity – 3) engine could block out ladder – 4) if hydrant OOS, may not be able to proceed to next hydrant b/c blocked in – 5) possible damage by falling debris

Question 18

If backstretching at a vacant building fire and it is evident that more than one line will be needed on the fire, what shall the office order?

Answer 18

second line to be droppend in front of the fire building before the pumper proceeds to the hydrant

Question 19

When supplying aerial to TL pipes, what diameter hose shall be used?

Answer 19

Largest diameter hose shall be used

Question 20

When stretching hand lines into exposures for operations into the fire building, what should be considered in a vacant building fire?

Answer 20

2 1/2” lines with solid stream nozzles should be considered

Question 21

What is the main objective in the placement of exterior streams at a vacant building fire?

Answer 21

to obtain the greatest coverage, while bearing in mind the safety of members involved. Tower ladders should be positioned to cover TWO sides of a building

Question 22

Who surveys the lot at a vacant building fire if a TL is going to be set up in it to operate?

Answer 22

MUST be surveyed by both officer and chauffeur (to determine the condition of the rubble and whether it will support the weight of the rig)

Question 23

At a vacant building fire where a T.L. is operating in a vacant lot, how should the T.L. boom be operated?

Answer 23

Narrow angles, over the front or rear of the apparatus. (SHOULD NOT be operated at right angles to the chassis at low elevations)

Question 24

Answer 24

No need for it

Question 25
