A) Purchase order B) Construction drawings C) Material safety data sheet D) Daily job log Answer: B Explanation: Construction drawings provide the detailed plans and specifications necessary to define the scope of work for the project. Question 2. Which calculation is essential when estimating the total cost of piping material for a fire sprinkler installation? A) Volume of water in the system
B) Linear footage of pipe required C) Number of laborers needed D) Total area of the building Answer: B Explanation: Estimating the linear footage of pipe needed is crucial for accurately calculating material costs. Question 3. Who is responsible for approving fire protection plans before installation begins? A) Project manager B) Authority Having Jurisdiction (AHJ) C) Building owner D) Fire sprinkler manufacturer
Question 5. In cost estimation, which factor is necessary to calculate labor costs for installing a fire main? A) Size of water storage tank B) Number of fire department connections C) Estimated labor hours D) Brand of sprinkler heads Answer: C Explanation: Labor cost is based on the estimated number of labor hours required for completion. Question 6. Which document typically contains the specifications for the types of sprinkler heads to be used? A) Purchase order B) Submittal package
C) Job hazard analysis D) Daily report Answer: B Explanation: The submittal package includes detailed specifications for all system components, including sprinkler heads. Question 7. What is the primary safety concern during trench excavation for underground fire main installation? A) Sprinkler head placement B) Pipe corrosion C) Soil collapse D) Water pressure Answer: C
Question 9. Which type of pipe joint is commonly used for underground fire mains? A) Threaded B) Solvent welded C) Mechanical joint D) Soldered Answer: C Explanation: Mechanical joints are preferred for underground use due to their strength and ease of assembly. Question 10. Why are thrust blocks installed in underground fire main systems? A) To prevent corrosion B) To anchor pipes against water pressure
C) To increase flow rate D) To support sprinkler heads Answer: B Explanation: Thrust blocks prevent pipe movement caused by internal water pressure at changes in direction or pipe size. Question 11. Which material is NOT commonly used for underground fire main piping? A) Ductile iron B) PVC (C900) C) Galvanized steel D) Copper Answer: D
Question 13. Which valve type is commonly used as an underground isolation valve for fire mains? A) Gate valve B) Ball valve C) Butterfly valve D) Check valve Answer: A Explanation: Gate valves provide reliable, full-flow isolation for underground fire main systems. Question 14. What is a Fire Department Connection (FDC) used for? A) Connecting the system to the public sewer B) Allowing fire department to supply water to the system
C) Testing the alarm system D) Venting trapped air Answer: B Explanation: FDCs allow firefighters to supplement system water supply during an emergency. Question 15. When installing a fire hydrant, which is the correct orientation for the steamer port? A) Facing the building B) Facing the street C) Facing away from the street D) Any direction Answer: B
Question 17. Which type of sprinkler system is typically used in areas subject to freezing temperatures? A) Wet-pipe B) Dry-pipe C) Deluge D) Preaction Answer: B Explanation: Dry-pipe systems are filled with air and only deliver water when activated, making them suitable for cold areas. Question 18. In a wet-pipe sprinkler system, what is the primary medium filling the pipes? A) Air B) Nitrogen
C) Water D) Carbon dioxide Answer: C Explanation: Wet-pipe systems are always filled with pressurized water, ready for immediate discharge. Question 19. What activates a deluge sprinkler system? A) Sprinkler head heat activation B) Manual pull station C) Activation of a separate detection system D) Loss of air pressure Answer: C
Question 21. Which component is required to prevent backflow from a fire protection system into the public water supply? A) Flow switch B) Backflow preventer C) Test header D) Alarm valve Answer: B Explanation: Backflow preventers keep system water from contaminating the public supply. Question 22. When is a fire pump required in a sprinkler system? A) When the municipal supply meets demand B) When system demand exceeds supply pressure
C) In all residential buildings D) Only for foam systems Answer: B Explanation: Fire pumps are installed when the available water pressure is insufficient for system needs. Question 23. What is the primary purpose of a jockey pump? A) Provide main system pressure B) Maintain system pressure, compensating for small leaks C) Suppress fire in the kitchen D) Test alarm activation Answer: B
Question 25. Which standard governs the installation of fire sprinkler systems? A) NFPA 10 B) NFPA 13 C) NFPA 24 D) NFPA 25 Answer: B Explanation: NFPA 13 is the standard for installation of sprinkler systems. Question 26. What is the K-factor of a sprinkler head? A) The activation temperature B) The orifice size
C) The discharge coefficient D) The sensitivity rating Answer: C Explanation: The K-factor is a discharge coefficient that relates flow to pressure for a sprinkler head. Question 27. Which type of pipe is most commonly used for aboveground fire sprinkler systems? A) Polyethylene B) Black steel C) Galvanized iron D) Ductile iron Answer: B
