1. A fire protection contractor is preparing a project involving the
installation of an automatic sprinkler system in a commercial
building. Which document should be treated as the primary basis
for determining the required sprinkler system design criteria,
subject to the adopted codes and approved plans?
A. The contractor's preferred installation method
B. The manufacturer's sales brochure
C. The approved construction documents and applicable adopted codes
and standards
D. The building owner's maintenance records
A.
The approved construction documents, together with the applicable
adopted codes and referenced standards, establish the governing design
and installation requirements. Contractor preferences or product
literature cannot override approved requirements.
, 2. Which organization publishes NFPA 13, the principal standard
governing the design and installation of automatic sprinkler
systems?
A. International Code Council
B. National Fire Protection Association
C. Occupational Safety and Health Administration
D. American Society of Mechanical Engineers
B.
The National Fire Protection Association (NFPA) publishes NFPA 13,
which provides detailed requirements for the design and installation of
automatic sprinkler systems in many commercial and industrial
applications.
3. What is the primary purpose of an automatic sprinkler system?
A. To replace the building fire alarm system
B. To provide emergency lighting during a fire
C. To detect and control or suppress a developing fire
D. To prevent all combustible materials from igniting
C.
Automatic sprinklers are intended to respond to heat from a developing
fire and discharge water to control or suppress the fire, limiting its
growth and reducing risks to occupants and property.
, 4. A sprinkler contractor is determining the hazard classification for an
occupancy. Which factor is most important in determining the
appropriate classification?
A. Building exterior color
B. Occupancy use, combustible loading, and fire characteristics
C. Number of parking spaces
D. Type of roofing contractor used
B.
Sprinkler hazard classification is based primarily on the characteristics of
the occupancy, including its use, combustible contents, storage
arrangements, heat-release potential, and other factors affecting fire
severity.
5. In hydraulic sprinkler calculations, what does the term “density”
generally represent?
A. Pipe wall thickness
B. Required water flow per unit area
C. Static pressure at the water main
D. Total number of sprinkler heads
B.
Sprinkler density represents the required water application rate over a
specified area, commonly expressed in gallons per minute per square
foot, and is a fundamental design parameter.
, 6. A contractor is calculating the flow from a sprinkler using the
standard sprinkler discharge relationship. Which formula is
generally used?
A. Q = P/K
B. Q = K√P
C. Q = K/P
D. Q = P²/K
B.
The sprinkler discharge equation is Q = K√P, where Q is flow, K is the
sprinkler discharge coefficient, and P is pressure at the sprinkler.
7. A sprinkler has a K-factor of 5.6 and is supplied with 25 psi at the
sprinkler. Approximately how much water will it discharge?
A. 14 gpm
B. 28 gpm
C. 56 gpm
D. 140 gpm
B.
Using Q = K√P, the discharge is 5.6 × √25 = 5.6 × 5 = 28 gpm. This
illustrates how sprinkler flow increases with the square root of pressure.
8. What is the principal purpose of a fire sprinkler waterflow alarm?
A. To manually close the building water supply
B. To indicate that water is flowing through the sprinkler system
