Question 83: Standard search priorities of the ___ search include largest numbers, remainder of hazard zone, and exposures.

tertiary (Correct answer)
primary (Correct answer)
secondary
rapid intervention

Correct answer: tertiary

While primary and secondary searches are fundamental, some advanced firefighting curricula or larger departments define a 'tertiary search' phase. This search typically occurs after the main fire is controlled and focuses on areas that were less immediately threatened but still within the hazard zone, or on adjacent exposures, to ensure all potential victims are found. It also includes a thorough check of areas where the 'largest numbers' of occupants might have been, ensuring no one was overlooked in earlier, more rapid searches.

Question 84: Which factor increases the water pressure available at the top of a tall standpipe?

Cooler water
A longer hose alone
A wider nozzle only
A more powerful pump at the base (Correct answer)

Correct answer: A more powerful pump at the base

A stronger pump overcomes elevation loss and boosts pressure at higher floors.

Question 85: What is a 'pancake collapse'?

A collapse where exterior walls fall outward away from the structure
A collapse where multiple floors fail and stack horizontally on top of one another (Correct answer)
A partial collapse of a roof section that falls into the attic space below
A collapse where one end of a floor slab falls while the other end remains partially supported by a wall

Correct answer: A collapse where multiple floors fail and stack horizontally on top of one another

A pancake collapse occurs when floors fail and fall flat, stacking on top of each other like pancakes, typically leaving very little survivable void space for occupants.

Question 86: Which type of control valve uses a circular disk inside a flat plate on top of the vale housing?

OS&Y
PIV
PIVA (Correct answer)
WPIV

Correct answer: PIVA

A Post Indicator Valve Assembly (PIVA) is a type of control valve commonly used in fire protection systems, such as those for sprinkler or standpipe systems. It features a circular disk inside a flat plate on top of the valve housing, which visually indicates whether the valve is in the open or closed position. This clear indicator allows firefighters to quickly assess the status of the water supply.

Question 87: Which of the following is 1/3 of 3/4?

3/4
2/3
1/4 (Correct answer)
1/3

Correct answer: 1/4

To find '1/3 of 3/4,' you multiply the two fractions together. Multiplying (1/3) by (3/4) gives (1 * 3) / (3 * 4) = 3/12. This fraction can then be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3, resulting in 1/4.

Question 88: A firefighter is using a Halligan bar to pry open a window. To achieve the maximum mechanical advantage and prying force, where should they apply force on the handle?

With short, rapid jolts near the adz end.
As far from the pry point (fulcrum) as possible. (Correct answer)
At the exact center of the handle.
As close to the pry point (fulcrum) as possible.

Correct answer: As far from the pry point (fulcrum) as possible.

This is a direct application of the principle of a Class 1 lever. Mechanical advantage is maximized by increasing the length of the lever arm where force is applied. Therefore, applying force at the end of the handle, furthest from the fulcrum (the point where the tool pivots), will generate the most prying force.

Question 89: A nozzle flows 95 gallons per minute. How many gallons flow in 7 minutes?

650
665 (Correct answer)
700
595

Correct answer: 665

95 x 7 = 665 gallons.

Question 90: 48\/-6

-8 (Correct answer)
8
-16
16

Correct answer: -8

This problem involves dividing a positive number by a negative number. When performing division with numbers of opposite signs, the result is always negative. Dividing 48 by 6 yields 8, so 48 divided by -6 results in -8.

Question 91: Which component of a Halligan bar is a broad, flat prying blade set at an angle to the shaft, primarily used for gapping and prying doors and windows?

The Pike
The Fork
The Adz (Correct answer)
The Horn

Correct answer: The Adz

The adz is the flat, wedge-shaped blade at the top of the Halligan bar, set at an angle to the main shaft. It is specifically designed to be driven between a door and its frame to create a gap for prying. The pike is the pointed end, and the fork is the two-pronged end.

Question 92: Which public alerting systems were installed on street corners and connected to a wired telegraph circuit within all fire stations in the jurisdiction?

Wired telegraph circuit boxes (Correct answer)
Basic alarm boxes
Telephone fire alarm boxes
Radio fire alarm boxes

Correct answer: Wired telegraph circuit boxes

Wired telegraph circuit boxes were early public alerting systems installed on street corners, allowing citizens to manually activate an alarm. These boxes were directly connected via a dedicated wired telegraph circuit to all fire stations in the jurisdiction, transmitting a coded signal that indicated the precise location of the alarm. This system was a foundational precursor to modern emergency call systems.

Question 93: Convert 0.27 + 0.33 to a fraction.

2/7
3/6
4/7
3/5 (Correct answer)

Correct answer: 3/5

First, sum the given decimal numbers: 0.27 + 0.33 equals 0.60. To convert 0.60 to a fraction, write it as 60/100, representing sixty hundredths. This fraction can then be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 20, resulting in the simplified fraction 3/5.

Question 94: What is the primary use of a roof ladder's hooks?

To connect two ladders together
To attach to a fire engine
To hoist equipment
To anchor the ladder over a roof ridge (Correct answer)

Correct answer: To anchor the ladder over a roof ridge

The folding hooks at the top secure the ladder over the peak of a pitched roof for stability.

Question 97: To the lowest terms, reduce 2/4 X 3/4.

6/4
5/16
3/8 (Correct answer)
6/12

Correct answer: 3/8

To multiply fractions, multiply the numerators together and the denominators together. So, (2/4) * (3/4) equals (2*3) / (4*4), which results in 6/16. To reduce this fraction to its lowest terms, divide both the numerator and the denominator by their greatest common divisor, which is 2, yielding 3/8.

Question 98: A tank loses 25 gallons per minute. How long until a 500-gallon tank empties?

25 minutes
20 minutes (Correct answer)
30 minutes
15 minutes
