Question 3
National Fire Incident Reporting System (NFIRS) information is transmitted to
the:
A. Emergency Management Agency
B. Department of Homeland Security
C. National Fire Protection Association
✅D. U.S. Fire Administration
Rationale: NFIRS data is collected and managed by the U.S. Fire Administration
to support national fire analysis.
Question 4
Tracking personnel working at an incident requires a standardized system to
establish:
A. Chain of command
B. Unity of command
C. Span of control
✅D. Accountability
Rationale: Accountability systems track personnel location, assignments, and
safety status.
Question 5
A firefighter receives conflicting orders from multiple supervisors. Which ICS
principle has been violated?
A. Chain of command
B. Division of labor
C. Span of control
✅D. Unity of command
Rationale: Unity of command requires each individual to report to only one
supervisor.

Question 6
One effective method for extinguishing fires in stacked Class A materials is to:
✅A. Use Class A foam
B. Use AFFF with a penetrating nozzle
C. Apply sand
D. Ignite a backfire
Rationale: Class A foam improves water penetration and cooling in porous,
stacked fuels.
Question 7
Which substance is classified as a hydrocarbon?
A. Ketone
✅B. Kerosene
C. Alcohol
D. Acetone
Rationale: Hydrocarbons consist solely of hydrogen and carbon; kerosene fits this
definition.
Question 8
Which nozzle is used with foam solution to produce low-expansion, short-lasting
foam?
✅A. Fog nozzle
B. Mechanical blower
C. Solid-bore nozzle
D. Water-aspirating foam nozzle
Rationale: Fog nozzles produce low-expansion foam suitable for quick
knockdown.

Question 9
Friction loss is best defined as:
A. The volume of water delivered by a nozzle
B. The force causing nozzle reaction
C. Pressure as water exits an opening
✅D. Pressure lost as water moves through hose
Rationale: Friction loss results from resistance between water and hose interior.
Question 10
Which statements regarding foam application are correct?
AFFF can be applied through a standard fog nozzle
Air-aspirating foam nozzles produce high-quality foam
Air-aspirating nozzles are recommended for protein foams
A. Statement 1 only
B. Statements 1 and 2 only
C. Statement 3 only
✅D. All three statements are true
Rationale: Each statement accurately reflects foam application principles.
Question 11
An advantage of Class A foam is that it:
A. Resists hydrocarbons
B. Self-seals on liquid surfaces
✅C. Allows water to penetrate dense materials
D. Works equally on Class B fires
Rationale: Class A foam reduces surface tension, improving penetration.
