CHAPTER 13 HOSE OPERATIONS & STREAMS UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS VERIFIED 2027 EDITION
1. What is the difference between a fire hose and a supply hose?
A fire hose carries water from the hydrant or water source to the pumper and then to the fire Supply hoses
transfer the water from its source to an apparatus fire pump
2. Failures or reduction and water supply or pressure from hydrants can result from. (7)
Damaged hydrant valves, and connections Broken water mains Greater demand than the system can
provide Hydrants located on dead end water mains Closed isolation valves Restricted MAINS Pipes or
hydrants that are frozen
3. What are the two primary types of fire hydrants used in North America?
Dry barrel and wet barrel
4. Regardless of location, designer type hydrant, discharge outlets are considered standard if they
contain the two following components
At least one large four or 4 1/2 inch outlet often referred to as pumper outlet nozzle or steamer connection
Two hose outlet nozzles for 2 1/2 inch couplings
5. Hydrant specifications require a blank inch valve opening for three-way standard hydrants, and a
blank inch connection to the water main
5 inch opening 6 inch to water main
6. Which standard sets the regulations for the number of threads per inch in the outside diameter of
the male thread
NFPA1963
7. What is a tri barrel hydrant designed for?
Use and climate with freezing temperatures
8. Where is the main control valve of the dry barrel hydrant located?
At the base or foot of the hydrant below the frost line
9. On a dry barrel hydrant, turning the stem in a counterclockwise direction opens or closes the
valve?
Opened the valve
10. What barrel hydrants are usually installed in which climate
Climate without prolonged periods of sub, freezing weather
11. Picture of a dry barrel hydrant

,12. Picture of a wet barrel hydrant
13. Firefighters use tools when making fire hydrant connections these include
Spanner wrenches Hydrant wrenches Rubber mallets Gate valves Hydrant valves
14. hydrant wrenches are primarily used to
Remove discharge caps from the fire hydrant outlets, and to open fire hydrant valves
15. Gate valves control the
Flow from a hydrant
2
, 16. What are a hydrant valves for main functions?
Allow additional hose lines to be laid to the hydrant Connect a Supply pumper to the hydrant Boost the
pressure in the original supply line without interrupting the flow of water in the line Allow the original
supply line to be connected to the hydrant and charged before the arrival of another pumper at the
hydrant
17. Four types of hose clamps
Screw down, press down, hydraulic press, wildland,
18. Pictures of different types of hose clamps
19. Opening a hydrant too fast may cause
The connected fire hose to flail uncontrollably as water pressure straightens the hose
20. Closing a hydrant too fast may cause
A surge and pressure(water hammer) within the water supply system, which can damage the system
piping or appliances attached to the system
21. If a hard intake is marked for vacuum, use only do not use it for
Hydra connections and pressurized systems only use it for static sources of water
22. What are two common rural water supply operations
Water shuttle operations and relay pumping
23. Water Shuffle Operation
Method of water supply by which mobile water supply apparatus continuously transport water between a
fill site and the dump site located near the emergency scene.
24. Relay Pumping
Use of two or more pumpers to move water over a long distance by operating them in series. Water
discharged from one pumper flows through hoses to the inlet of the next pumper, and is then pumped to
the next pumper in line.
