B) Owner's Certificate
C) Architect’s Program Statement
D) Fire Marshal’s Occupancy Permit
E) Hydraulic Data Plate
Correct Answer: B) Owner's Certificate

of a K-5.6 sprinkler at the same pressure?
A) 110%
B) 120%
C) 140%
D) 160%
E) 200%
Correct Answer: C) 140%
Rationale: As shown in NFPA 13 Table 7.2.2.1, the K-8.0 sprinkler has a nominal discharge
capacity that is 140% of the standard K-5.6 sprinkler.
Question 3

rectangular area having a dimension parallel to the branch lines at least how many times the
square root of the sprinkler operation area?
A) 1.0
B) 1.2
C) 1.4
D) 1.5
E) 2.0
Correct Answer: B) 1.2
Rationale: NFPA 13 (28.2.4.2.1) stipulates that for hydraulic calculations using the
density/area method, the dimension of the design area parallel to the branch lines must be
at least 1.2 times the square root of the total area of sprinkler operation.

Question 4
In the International Building Code (IBC), an intermediate level between the floor and ceiling of
any story is defined as a:
A) Crawl space
B) Penthouse
C) Mezzanine
D) Attic
E) Balcony
Correct Answer: C) Mezzanine
Rationale: According to IBC Section 202, a mezzanine is an intermediate level or levels
between the floor and ceiling of any story.

B) Flow location and residual pressure
C) Color of the hydrant and location of the nearest valve
D) Name of the water treatment plant operator
E) The depth of the water main below grade
Correct Answer: B) Flow location and residual pressure
Rationale: NFPA 13 (4.5.1) requires water supply information to include the static pressure,
residual pressure, and the flow location to accurately calculate the available water for the
system.

EXCEPT:
A) Melamine
B) Fluoroplastics
C) Phenolic
D) Polystyrene
E) Urea formaldehyde
Correct Answer: D) Polystyrene
, 4
Rationale: Polystyrene is a Group A plastic because of its high heat release rate. Group C
plastics (NFPA 13-20.4.7) include less combustible plastics like Phenolic and Fluoroplastics.
Question 11

B) Ordinary Hazard (Group 2)
C) Extra Hazard (Group 1)
D) Extra Hazard (Group 2)
E) Special Occupancy
Correct Answer: C) Extra Hazard (Group 1)
Rationale: NFPA 13 (3.3.141.1) defines Extra Hazard Group 1 as occupancies with very high
combustibility and high heat release but little or no flammable/combustible liquids.
Question 12
All threaded pipe and fittings used in water-based fire protection systems must have threads cut
to which specific standard?
A) ASTM A53
B) ASME B1.20.1
C) NFPA 70
D) AWWA C110
E) ANSI B16.1
Correct Answer: B) ASME B1.20.1
Rationale: NFPA 13 (7.4.1) requires that all threaded pipe and fittings have threads cut to
the ASME B1.20.1 Pipe Threads, General Purpose standard.
Question 13
During a water flow test, what coefficient (C) is used to calculate the discharge of a hydrant
outlet that is smooth and well-rounded?
A) 0.70
B) 0.80
C) 0.90
D) 0.95
E) 1.0
Correct Answer: C) 0.90
Rationale: According to NFPA 291 (Figure 4.9.1), an outlet that is smooth and well-rounded
is assigned a coefficient of 0.90 for flow calculations.
