a. The ladder should be placed so the top rung is even with the top of the roof
b. One full rung should extend beyond the roof line
c. Several rungs should extend beyond the roof

A fire has extended from the building of origin to the cockloft of an adjoining store.
The proper fire attack would involve
a. Opening the roof of the exposure and operate a fog pattern into the roof opening of the exposure only
b. Opening the roof of the exposure, pulling the ceiling and attacking the fire from below
c. Opening the roof of the fire building and attacking the fire by placing ladders into the cockloft and attacking from the unburned side of the cockloft
d. Do not open the roof of the fire building or exposure but pull the ceiling and attack the fire from below
b. Opening the roof of the exposure, pulling the ceiling and attacking the fire from below.
There is a working fire in the basement of a large structure with only one opening to the basement that is being used to attack the fire. The best venting option would be to
a. Vent through the one opening to the first floor and then attack the fire after the heavy smoke has been relieved
b. Open the floor between the basement and the first floor directly over the fire if possible and then open all windows on the first floor
c. Open the floor between the basement and the first floor near a first floor window and vent out the first floor window
d. Do not vent this fire and attack via the one available opening
b. Open the floor between the basement and the first floor directly over the fire if possible and then open all windows on the first floor.
Fire-resistive construction
a. Restricts fire spread.
b. Results in extremely high temperatures in the fire area.
c. Results in extremely heavy accumulations of smoke and fire gases.
d. All of the above.
d. All of the above.
The best way to ventilate an occupied fire resistive structure is
a. At the top of the stairways, particularly when there is a scuttle opening to the roof
b. Using vertical shafts that serve the entire building
c. By any vertical means
d. Through the windows
d. Through the windows
When venting an occupied fire resistive building, start
a. By venting the fire floor
b. By venting the floor above the fire
c. By venting the hallway and stairway
d. At the top and work down
a. By venting the fire floor.
Elevator controls are

When indications of a smoldering fire are visible from the exterior
a. Vent from the highest point possible before entering the building
b. Vent from the highest point possible once a charged attack line is in position on the interior
c. Vent from the lowest possible point before entering the building
d. Vent from the lowest possible point once a charged attack line is in position and charged on the interior
a. Vent from the highest point possible before entering the building.
