IFSTA CHAPTER 13: HOSE
OPERATIONS AND HOSE STREAMS
(LATEST 2026/ 2027 UPDATE)
QUESTIONS AND 100% CORRECT
VERIFIED ANSWERS| GRADE A+
1. According to NFPA 1962, how often should service testing be performed on fire hose?
A. Annually
B. Every six months
C. Every two years
D. After every structural fire use
Answer: A
Conceptual Explanation: NFPA 1962 requires that fire hose be service tested at least
annually to ensure its integrity and safety during operations.
2. Which type of hose roll is primarily used when the hose will be deployed directly from the
roll for a connection?
A. Donut roll
B. Twin donut roll
C. Straight roll
,D. Self-locking twin donut roll
Answer: A
Conceptual Explanation: The donut roll is used when the hose will be deployed for use
because both couplings are on the outside, allowing for easy access and preventing kinks.
3. What is the primary disadvantage of a non-collapsible intake hose?
A. It cannot be used for drafting.
B. It is prone to internal vacuum collapse.
C. It is heavy and difficult to maneuver.
D. It cannot be used for pressurized hydrants.
Answer: C
Conceptual Explanation: Non-collapsible intake hose (hard suction) is designed to
withstand vacuum but is heavy and lacks flexibility compared to soft sleeve hose.
4. Which hose load is best suited for departments that frequently use large diameter hose
(LDH) for supply lines?
A. Accordion load
B. Flat load
C. Horseshoe load
D. Triple layer load
, Answer: B
Conceptual Explanation: The flat load is the easiest to load and results in less wear on the
hose lining, making it ideal for large diameter hose.
5. What occurs when the flow of water through a fire hose is suddenly stopped?
A. Friction loss
B. Water hammer
C. Cavitation
D. Laminar flow
Answer: B
Conceptual Explanation: Water hammer is a pressure surge caused by the sudden stop or
change in direction of water flow, which can damage hose, pumps, and water mains.
6. Which nozzle type is designed to produce a stream with the greatest reach and
penetration?
A. Fog nozzle
B. Smooth bore nozzle
C. Broken stream nozzle
D. Cellar nozzle
Answer: B
