discretion of selecting the tools deemed necessary to complete his/her assignment? (2.6D)
a Officer
b Chauffeur
c OV FF
d Roof FF

Answer 9

9. B
10. For a Top Floor Fire:
    A. Raise and position aerial to roof of exposure for use by roof
    firefighter and OV (who will be going to roof).
    B. Commence venting top floor windows as coordinated with the
    Ladder Company Officer inside the fire area to be vented.
    C. The top floor fire often permits search of all but the immediate fire
    area by members of the Inside Team. One of these members may
    make their way to a front window to inform the chauffeur that they
    are “in”, relieving him/her of the necessity of performing VEIS
    from the aerial.
    When the chauffer is not contacted by a member of the Inside
    Team, the chauffeur must assume that they have been unable to get
    past the fire, or are otherwise heavily engaged. In such instances
    and where fire conditions permit, the chauffeur should attempt
    entry and search.

11. D
12. TOP FLOOR FIRE
    For a fire on the top floor, the OV will proceed to the roof with the saw
    and halligan tool.

ROOF POSITION (Second Arriving Ladder – Brownstone Building)

in a Brownstone, would be following Department procedures if carrying what set of tools to the
roof? (2.7)
a Saw and 6ft Halligan hook
b Saw and Halligan tool
c Saw and 6ft hook
d Saw and LSR

Answer 15

15. A

ROOF POSITION (Second Arriving Ladder – Brownstone Building)

   at an intersection where the units can come in from one direction and
   leave by another. This Foam Assembly Point and direction of access
   should be relayed to the dispatcher for transmittal over the department
   radio. A Battalion Chief, preferably a Foam Coordinator, should be
   assigned this duty.
