Q1: Fire Behavior & Chemistry
Which phase of fire development is characterized by the transition from fuel-controlled to
ventilation-controlled burning, often signaled by a sudden increase in compartment
temperature and rollover?
A. Incipient
B. Growth
C. Flashover
D. Fully developed
Answer: B
Rationale: IFSTA 7th Edition, Chapter 2 (Fire Behavior & Chemistry), identifies the growth phase
as the period when heat release rate increases rapidly, flame spread accelerates, and the fire
may become ventilation-controlled. Rollover (flames rolling across the ceiling) is a key indicator.
Incipient (A) is too early; flashover (C) is near-end of growth phase; fully developed (D) is post-
flashover.
Q2: Building Construction
Which type of wall, extending from the foundation to the roof, is designed to limit fire spread
vertically within a structure?
A. Fire wall
B. Party wall
C. Fire barrier wall
D. Partition wall
Answer: A
Rationale: IFSTA 7th Edition, Chapter 3 (Building Construction), defines a fire wall as a
continuous wall from foundation to roof with fire-resistance ratings (typically 3–4 hours) that
remains structurally stable even if the building on either side collapses. Party walls (B) are
shared but not always fire-rated; fire barrier walls (C) are not continuous; partition walls (D) are
non-load-bearing and low-rated.
,Q3: Firefighter Safety & Health
Under NFPA 1500, how often must a fire department conduct a comprehensive safety and
health program evaluation?
A. Annually
B. Biennially
C. Every 3 years
D. Every 5 years
Answer: C
Rationale: NFPA 1500 (2022 ed.) §4.2.1 requires a formal written evaluation of the entire safety
& health program at least every three years. Annual (A) reviews are encouraged but not
mandatory for the full program.
Q4: Personal Protective Equipment (PPE) & SCBA
What is the minimum service-life temperature (in °C) that the NFPA 1971 structural firefighting
ensemble must withstand before thermal shrinkage exceeds 10 %?
A. 200 °C
B. 260 °C
C. 300 °C
D. 350 °C
Answer: B
Rationale: NFPA 1971 (2018 ed.) §7.3.1 specifies 260 °C (500 °F) for 5 min with ≤10 % shrinkage.
200 °C (A) is too low; 300–350 °C (C, D) exceed test parameters.
Q5: Forcible Entry, Search & Rescue
When forcing an outward-opening metal door with a hydraulic spreader, the FIRST attack point
recommended by IFSTA is:
A. Hinge side top
B. Latch side mid-point
C. Lock edge at the strike
D. Threshold
Answer: C
,Rationale: IFSTA 7th Edition, Chapter 9 (Forcible Entry), prioritizes the lock edge (strike area) on
outward doors because spreading the latch/bolt from the jamb is fastest. Hinge attack (A) is
secondary; threshold (D) is ineffective.
Q6: Water Supply, Hose, Streams
Which friction-loss coefficient (C) for 2½-in. (65 mm) hose is used in the formula FL = C × Q² × L
when calculating engine pressure?
A. 0.8
B. 1.1
C. 2.0
D. 12.0
Answer: C
Rationale: IFSTA 7th Edition, Chapter 13 (Water Supply), Table 13.2 lists C = 2.0 for 2½-in. hose.
0.8 (A) is for 3-in.; 1.1 (B) for 2-in.; 12.0 (D) for 1½-in.
Q7: Ventilation, Fire Suppression
During positive-pressure attack (PPA), the blower is placed how many diameters from the entry
door to maximize airflow efficiency?
A. 1–2
B. 3–6
C. 8–10
D. 12–15
Answer: B
Rationale: IFSTA 7th Edition, Chapter 10 (Ventilation), specifies 3–6 blower diameters from the
entry to create a tight air cone. Closer (A) causes turbulence; farther (C, D) reduces pressure.
Q8: Loss Control, Fire Cause Determination
Which NFPA standard guides the professional practice for fire and explosion investigations?
A. NFPA 921
B. NFPA 1033
C. NFPA 1500
D. NFPA 1730
, Answer: A
Rationale: NFPA 921 (2022) is the Guide for Fire & Explosion Investigations. NFPA 1033 (B) sets
investigator professional qualifications; 1500 (C) safety; 1730 (D) prevention.
Q9: Fire Behavior & Chemistry
The heat-release rate (HRR) at which flashover typically occurs in a residential room is closest to:
A. 100 kW
B. 500 kW
C. 1 MW
D. 5 MW
Answer: C
Rationale: IFSTA 7th Edition cites ≈1 MW (C) as the HHR threshold for flashover in typical 12 ×
14 ft room. 100 kW (A) is incipient; 500 kW (B) pre-flashover; 5 MW (D) fully-developed.
Q10: Building Construction
A Type IV (Heavy Timber) building must have columns that are at least ___ in. × ___ in. nominal
dimension.
A. 4 × 6
B. 6 × 8
C. 8 × 8
D. 10 × 10
Answer: C
Rationale: NFPA 220 and IFSTA 7th Edition require minimum 8 × 8 in. nominal wood columns for
Type IV construction. 6 × 8 (B) is insufficient.
Q11: Firefighter Safety & Health
According to NFPA 1582, which condition is an absolute contraindication to firefighting duties?
A. Controlled hypertension
B. Corrected 20/40 vision
C. Current insulin-treated diabetes with hypoglycemic episodes
D. Prior ACL reconstruction
