Q1: A water-based fire protection systems layout technician is preparing a submittal package for a
new wet-pipe sprinkler system in a fully sprinklered office building. Which NFPA standard governs
the installation and layout requirements for this sprinkler system in the 2026/2027 exam reference
cycle?
A. NFPA 13, Standard for the Installation of Sprinkler Systems (2022 edition) [CORRECT]
B. NFPA 14, Standard for the Installation of Standpipe and Hose Systems (2019 edition)
C. NFPA 20, Standard for the Installation of Stationary Fire Pumps (2022 edition)
D. NFPA 25, Standard for Water-Based Fire Protection Systems (2020 edition)
Correct Answer: A
Rationale: NFPA 13 (2022) is the governing installation standard for sprinkler system layout, spacing,
obstruction, and hydraulic design criteria and is the referenced edition for the 2026/2027 NICET Water-Based
Systems Layout exams. Option B applies to standpipe and hose system installation, not general sprinkler layout.
Option C applies to stationary fire pump installation and performance, and Option D (NFPA 25) governs
inspection, testing, and maintenance after acceptance, not design or layout.
Q2: During the design of a combined sprinkler and standpipe system for a 24-story office tower, the
layout technician must document the type, location, and pressure requirements of Class I hose
connections. Which NFPA standard provides the governing requirements for standpipe system
classification and installation?
A. NFPA 22, Standard for Water Tanks for Private Fire Protection (2018 edition)
B. NFPA 20, Standard for the Installation of Stationary Fire Pumps (2022 edition)
C. NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants (2022 edition)
D. NFPA 14, Standard for the Installation of Standpipe and Hose Systems (2019 edition)
[CORRECT]
Correct Answer: D
Rationale: NFPA 14 (2019) governs standpipe system types (Class I, II, and III), hose connection placement,
minimum outlet pressures, and maximum system working pressure for standpipe systems. Option A governs
private fire service water tanks, Option B governs fire pump installation, and Option C is a recommended practice
for hydrant flow testing and color marking; none of these classify hose connections or set standpipe outlet pressure
criteria.

Q3: A hydraulic design for a high-rise project indicates that the street water supply cannot meet the
combined sprinkler and standpipe demand, so a stationary fire pump will be installed. Which NFPA
standard establishes the performance, controller, and acceptance testing requirements the layout
technician must reference in the pump specification?
A. NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants (2022 edition)
B. NFPA 13, Standard for the Installation of Sprinkler Systems (2022 edition)
C. NFPA 20, Standard for the Installation of Stationary Fire Pumps (2022 edition) [CORRECT]
D. NFPA 22, Standard for Water Tanks for Private Fire Protection (2018 edition)
Correct Answer: C
Rationale: NFPA 20 (2022) governs stationary fire pump selection, rated capacity and pressure curve
requirements, controllers, power supply, sensing lines, and field acceptance testing. Option B covers the sprinkler
system downstream of the pump but not pump unit performance. Option A addresses public hydrant flow testing
and marking, and Option D addresses water storage tanks, so none of these substitutes for NFPA 20 pump
requirements.
Q4: The project water supply will be augmented by an on-site ground-level steel suction tank serving
the fire pump. The layout technician must document tank sizing, refill arrangements, and freeze
protection details on the plans. Which NFPA standard governs these water storage tank requirements?
A. NFPA 291 (2022)
B. NFPA 22, Standard for Water Tanks for Private Fire Protection (2018 edition) [CORRECT]
C. NFPA 14 (2019)
D. NFPA 72, National Fire Alarm and Signaling Code
Correct Answer: B
Rationale: NFPA 22 (2018) governs private fire protection water tanks, including sizing for the required
duration, refill arrangements, heat circulation and heating equipment, and documentation of the tank supply
arrangement. Option A is only a recommended practice for flow testing and hydrant marking. Option C governs
standpipes and hose systems, and Option D governs fire alarm and signaling, none of which address tank
construction, heating, or refill.
Q5: Before finalizing hydraulic calculations, the layout technician needs to evaluate the municipal
water supply and observes that hydrants on the public main are painted different colors indicating
available flow. Which NFPA document establishes the recommended fire flow testing procedures and
the hydrant color-marking classification system?
A. NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants (2022 edition)
[CORRECT]
B. NFPA 291 is not applicable; flow testing is covered by NFPA 13 only
C. NFPA 20 (2022), because flow testing applies only to fire pumps
D. NFPA 14 (2019), because flow testing applies only to standpipe systems
Correct Answer: A
Rationale: NFPA 291 (2022) establishes the two-hydrant flow test procedure and the hydrant marking classes:
Class AA (1,500 gpm or more, light blue), Class A (1,000 to 1,499 gpm, green), Class B (500 to 999 gpm, orange),
and Class C (fewer than 500 gpm, red). Option B incorrectly dismisses the document, Option C wrongly ties flow
testing to pumps, and Option D wrongly ties it to standpipes; supply evaluation for any water-based system uses
NFPA 291 methods.
