$$75^{\circ}$$

How far should the butt of the ladder be placed from the building?

$$2-3\,ft$$

Which hose maintenance task must be performed annually versus monthly?

Hose testing is performed annually, while hose inspection is performed monthly.

What is the ideal span of control according to ICS standards?

$5$ (with a range of $3-7$).

What is the target angle for approaching a vehicle fire?

$$45^{\circ}$$

At approximately what temperature does flashover occur?

$$\approx 1000^{\circ}F$$

What are the priority areas to check during a search and rescue operation?

Bedrooms and areas near exits.

In the ICS structure, which officer has the authority to stop unsafe acts?

What is the difference between Direct and Indirect fire attack?

Direct attack puts water on the fuel, while indirect attack puts water on the gases.

Which class of foam is specifically used during overhaul?

What is the leading cause of death for firefighters?

Cardiac-related issues.

What is the recommended temperature for a rehabilitation (rehab) area?

$$70^{\circ}F$$

What is the difference between chemical penetration and permeation in HazMat?

Penetration occurs when chemicals enter through cuts or openings, whereas permeation is when a chemical passes through the PPE material itself.

Identify the three HazMat zones and their safety status.

Hot Zone (hazard present), Warm Zone (decontamination), and Cold Zone (safe area).

Which building construction type is considered "fire-resistive"?

Type I.

Why is balloon frame construction more dangerous than platform frame construction?

Balloon frame construction allows fire to spread vertically very fast through wall cavities.

What characterizes a "Crown fire" in wildland firefighting?

It burns fuels above ground in the treetops.

Which fuel size is considered a common indicator for wildland fire behavior?

10-hour fuels.

What volume of water defines a master stream?

$$\geq 350\,gpm$$

Should a sprinkler system be shut off immediately upon arrival at a scene?

No, it should operate until the fire is controlled.

Which NFPA standard covers Firefighter Professional Qualifications?

NFPA 1001.

Which NFPA standard governs PPE (turnout gear)?

Which hose deployment method is specifically used for stairs?

The S method.

What is the Z method of hose deployment used for?

Upper floors or standpipe operations.

What does the term "Overlay" refer to in hose operations?

Placing a second hose over a first hose when fire extends upward; it is a deployment method, not an attack method.

In HazMat operations, what is the difference between Gross decon and Technical decon?

Gross decon is the quick removal of bulk contamination, while Technical decon is detailed, step-by-step cleaning.
