Question 1
Dry powder extinguishers are specifically rated for use on which of the following?
A) Flammable liquids
B) Ordinary combustibles
C) Combustible metals
D) Energized electrical equipment
E) Cooking oils and fats
Correct Answer: C) Class D
Rationale: Class D fires involve combustible metals such as magnesium or potassium. Dry
powder agents are designed to smother these metals, whereas "dry chemical" agents are
used for Classes A, B, or C.
Question 2
Halon fire extinguishers are primarily designed for use on which classes of fire?
A) Class A and B
B) Class B and C
C) Class C and D
D) Class A and K
E) Class D only
Correct Answer: B) Class B and C
Rationale: Halon is a liquefied gas extinguishing agent that is effective on flammable liquids
(B) and electrical fires (C) because it leaves no residue and is non-conductive.
Question 3
A portable fire extinguisher featuring a blue circle with a letter designation in the center is rated
for use on:
A) Ordinary combustibles
B) Flammable liquids
C) Energized electrical equipment
D) Combustible metals
E) Kitchen grease fires
Correct Answer: C) Class C
Rationale: The NFHS/NFPA coding system uses color-coded shapes: Green Triangle (A),
Red Square (B), Blue Circle (C), and Yellow Star (D).
Question 4
Pump tank extinguishers are most commonly used to apply which extinguishing agent?
, 2
A) Aqueous Film Forming Foam (AFFF)
B) Carbon Dioxide
C) Dry Chemical
D) Water
E) Halon
Correct Answer: D) Water
Rationale: Pump tank extinguishers are manual devices used primarily on Class A fires,
allowing a firefighter to pump water from a tank onto the fire.
Question 5
When drying synthetic fiber rope after cleaning, which of the following precautions should be
taken?
A) Dry it in an industrial oven
B) Hang it in direct sunlight to speed up the process
C) Keep it out of direct sunlight
D) Apply a thin layer of oil to prevent brittleness
E) Coil it tightly while still wet
Correct Answer: C) Out of sunlight
Rationale: Synthetic fibers are susceptible to ultraviolet (UV) degradation. Sunlight can
weaken the rope's core and mantle over time.
Question 6
Which substance should be applied to wooden tool handles to prevent roughness, splintering, and
warping?
A) Engine oil
B) Boiled linseed oil
C) Polyurethane gloss
D) Red paint
E) Grease
Correct Answer: B) Boiled linseed oil
Rationale: Linseed oil preserves the wood by keeping it hydrated and flexible. Painting
handles is prohibited as it can hide cracks or damage.
Question 7
What is the main advantage of the donut roll when preparing fire hose?
A) It is the easiest roll to perform by one person
B) It protects the male coupling inside the roll
C) Both ends of the hose are available on the outside of the roll
D) It creates a smaller diameter roll for storage
E) It allows the hose to be dragged through debris without snagging
Correct Answer: C) Both ends are available on the outside of the roll
, 3
Rationale: The donut roll allows the firefighter to access both couplings immediately,
facilitating quicker connections compared to a straight roll.
Question 8
When a hose is unloaded at the scene of a fire and the pumper proceeds to the water source, this
operation is known as:
A) A reverse lay
B) A tandem lay
C) A forward lay
D) A split lay
E) A pre-connect lay
Correct Answer: C) A forward lay
Rationale: In a forward lay, the pumper stops at the hydrant to drop off the hose and then
drives toward the fire. A reverse lay is when the pumper starts at the fire and drives to the
hydrant.
Question 9
In kernmantle rope construction, approximately what percentage of the rope’s total strength is
provided by the outer sheath (the mantle)?
A) 10 to 15 percent
B) 25 to 30 percent
C) 50 percent
D) 70 to 75 percent
E) 90 percent
Correct Answer: B) 25 to 30 percent
Rationale: The inner core (kern) provides the majority of the strength (70-75%), while the
mantle (sheath) protects the core and provide the remaining 25-30% of the strength.
Question 10
The overall strategy of a fire incident is determined by the Incident Commander and is generally
categorized into which two modes?
A) Primary and Secondary
B) Fast and Slow
C) Interior and Exterior
D) Offensive and Defensive mode
E) Search and Suppress
Correct Answer: D) Offensive and Defensive mode
Rationale: Offensive mode involves an aggressive interior attack, while defensive mode
focuses on exposure protection and exterior streams when the building is too dangerous to
enter.

Question 11
What does the "Automatic Number Identification" (ANI) feature of an enhanced 911 system
provide to the emergency dispatcher?
A) The caller's GPS coordinates
B) The caller's name and billing address
C) The caller's phone number
D) The nearest fire station's location
E) The caller's medical history
Correct Answer: C) Show the caller's phone number
Rationale: Enhanced 911 systems use ANI to display the phone number and ALI (Automatic
Location Identification) to display the address/location.
Question 12
Which of the following is NOT a physical or psychological limitation that affects a firefighter's
ability to use an SCBA?
A) Claustrophobia
B) Physical conditioning
C) Facial hair
D) Oxygen cylinder size
E) Respiratory capacity
Correct Answer: D) Oxygen cylinder size
Rationale: Cylinder size is an equipment specification, not a human limitation. Human
limitations include physical fitness, lung capacity, and the presence of facial hair which
prevents a proper seal.
Question 13
When refilling an SCBA cylinder, the cylinder must be:
A) Placed in a bucket of ice water
B) Hand-held to monitor for heat buildup
C) Placed in a fragmentation containment or other shielded device
D) Filled as quickly as possible to increase pressure
E) Emptied completely before the refill starts
Correct Answer: C) Placed in a fragmentation containment or other shielded device
Rationale: A fill station or fragmentation chamber protects the operator in the event of a
catastrophic cylinder failure (explosion) during the high-pressure filling process.
Question 14
What is the approximate flame temperature of an oxyacetylene cutting torch?
A) 1000 degrees F
B) 2500 degrees F
C) 5000 degrees f
